Alışılmadık Bir Çocuk İstismarı Vakası: Şarbon Bulaştırılması
(2020) Asirdizer, Mahmut; Etli, Yasin; Demir, Uğur
Çocuk istismarı, 18 yaşın altındaki çocuklara yönelik, sorumluluk, güven veya güç ilişkisi bağlamında, çocuğun sağlığına, hayatta kalmasına, gelişimine veya onuruna zarar veren hareket, hareketler veya eylemsizlikler şeklindeki davranışlar olarak tanımlanmaktadır. Bu olgu sunumunda çocuğa yetişkinler tarafından kasıtlı bir şekilde Şarbon bulaştırılmasını içeren değişik tipte bir çocuk istismarı olgusunu tartışmak amaçlanmıştır. 14 yaşında erkek olguya yetişkinler tarafından şarbon ile enfekte bir ineğin et parçalarına ve kanına temasa zorlanarak şarbon enfeksiyonu kapmasına neden olunmuştur. Yapılan adli tıbbi değerlendirme sonucunda olgumuzun değişik tipte bir çocuk istismarına maruz kaldığı ortaya çıkarılmıştır. Ayrıca, bulaşıcı hastalıkların bildirilmesinde yetkin ve sorumlu kişilerin yeterli dikkat ve özeni göstermemiş olmalarının son derece tehlikeli durumlara yol açabileceği de görülmüştür.

(Dove Medical Press Ltd, 2023) Ozgurluk, Izzet; Tastekin, Burak; Hira, Sila Yazkan; Gungorer, Bulent; Hekimoglu, Yavuz; Keskin, Huseyin Levent; Asirdizer, Mahmut
Purpose: A significant increase in physical intimate partner violence (IPV) cases has been reported from many countries during the COVID-19 pandemic, and particularly during lockdown periods. The current study's objectives are to define the COVID-19 pandemic's impact on physical IPV against pregnant women in Ankara. Patients and Methods: During the one-year pre-pandemic and two-year pandemic, records of patients who sent by the judicial authorities to the Obstetrics and Gynecology Emergency Room (ER) at Ankara City Hospital were reviewed, and pregnant women who had been subjected to IPV were identified. Results: Of pregnant women 19.1% in the pre-pandemic period, 29.4% in the first year and 51.5% in the second year of the pandemic period exposed to IPV. The mean age of IPV victims was 28.8 & PLUSMN; 6.5 years. Most ER applications were in the evening hours (48.5%), and majority of assailants were the victim's husband (77.9%). Vast majority of victims were multigravida women (89.7), and most of the traumas were localized in abdomen and genitalia (50%). Three of the women (4.4%) had miscarriage. Conclusion: The increase in cases of IVP against pregnant women during the pandemic was striking, according to the current study. We think that this first study from Turkey on the IPV that pregnant women are exposed to during the pandemic can lead to extensive research focused on measures against IPV during pandemics, such as dissemination of telephone applications for IPV victims, increasing home visits by marriage therapists, and intensifying of education campaigns against violence.
Association of Ramadan and Death Rates in a Metropolitan City in Turkey: a Review of Literature and a Seasonally Adjusted Study
(Springer, 2024) Kartal, Erhan; Etli, Yasin; Asirdizer, Mahmut
In this study, death rates for a metropolitan city were analyzed over a period of 33 years to investigate any potential relationship between the month of Ramadan and death rates. The study also aimed to obtain seasonally adjusted results using time series analysis. Ultimately, the total evaluation of the 33-year period revealed no significant variation in death rates between Ramadan and non-Ramadan periods. Separate analyses for each season with time series also yielded no significant findings for most parameters, with the exception that the number of female deaths during Ramadan in winter was significantly higher than expected. According to these results, the increase in the number of deaths observed among women during the winter Ramadan period requires further investigation to determine whether a causal relationship exists. The use of seasonally adjusted approaches and time series analyses in future Ramadan and health studies is crucial for the accuracy of the results.

(Soc Chilena Anatomia, 2015) Tatlisumak, Ertugrul; Yavuz, Mehmet Sunay; Kutlu, Necip; Asirdizer, Mahmut; Yoleri, Levent; Aslan, Asim
The aims of this study were to determine various morphometric measurements of auricle, to investigate asymmetry and its relation with handedness in both sexes. Main morphometric measurements of both auricles and hand preferences were determined on 200 male and 200 female healthy university students. All measurements of the auricles were larger in males than the corresponding ones in females and all the differences except earlobe widths were statistically significant. All measurements of left and right auricles were statistically significantly different in both sexes except earlobe length in males, and distance from the highest point of the auricle to the bottom of the intertragic notch and earlobe length in females. Auricle length and distance from the highest point of the auricle to the bottom of the intertragic notch had higher values at the left side and all other measurements were larger at the right side. There was no significant difference between the measurements of the corresponding auricles of the righthanded and lefthanded subjects. All measurements were larger at the right side except auricle length and distance from the highest point of the auricle to the bottom of the intertragic notch in righthanded and lefthanded subjects and all differences except earlobe length were significantly different in righthanded subjects as in the total population but in lefthanded subjects the difference of the auricle width was not significant, either. There was an apparent asymmetry of right and left auricles of normal people in the current study which should be taken in to consideration in plastic surgeries of the external ear, designing the ear devices and forensic applications of earprints.
Bütan Gazı Soluması Sonucu Meydana Gelen İki Ani Ölüm Olgusunda Olay Yeri ve Otopsi Bulguları
(2023) Kartal, Erhan; Etli, Yasin; Demir, Uğur; Ata, Uğur; Asirdizer, Mahmut
Solvent inhalasyonu halen dünya çapında gençlerin morbidite ve mortalitesinden sorumlu olan ve toplum üzerinde olumsuz etkileri bulunan önemli bir halk sağlığı sorunudur. Türkiye'de solvent inhalasyonu, sigara ve alkol bağımlılığından sonra en sık görülen madde kötüye kullanımı olup, bütan ve propanın en sık solunan maddeler olduğu bildirilmiştir. Bu çalışmada, biri intihar, diğeri kaza ile n-bütan solunması sonucu meydana gelmiş iki ölüm vakasının patoloji ve toksikolojik analiz sonuçları ile olay yeri bilgileri sunulmaktadır. Literatürde, bütan gazı solunmasına bağlı olarak hastaneye kaldırılan olgularda ve ölüm olgularında klinik bulgular ayrıntılı olarak tanımlanmış ise de, olay yeri ve otopsi bulgularını tanımlayan makale sayısı sınırlıdır. Bu olgu sunumunda, özellikle olay yeri ve ölü muayenesinde pratisyen hekimlerin karşılaşabilecekleri bulguların ve otopsi bulgularının tanımlanması amaçlanmıştır. Sonuç olarak, ceset muayenesine katılan pratisyen hekimlerin doğru toksikolojik analizler ve ölüm sebebinin doğru tespit edilebilmesi için, olay yeri ve ceset üzerindeki bulgular konusunda dikkatli olmaları önemlidir. Bu hekimlerin, cesede yakın yerde bulunan tiner, yapıştırıcı veya gaz kaynağı, cesedin başına geçirilmiş naylon torba, cesedin yakınında veya giysilerinde bulunan kusmuk lekeleri gibi bulguların varlığı veya yokluğu konusunda adli tıp uzmanlarına ipuçları vermeleri gerekmektedir.

(2022) Asirdizer, Mahmut; Kösem, Mehmet Esat; Kartal, Erhan; Akburak, Ömer
Cinsel taciz, tüm halka açık yerlerde insanları etkileyen sosyal bir sorun olarak tanımlanmaktadır. İnternetin yaygınlaşması aynı zamanda cinsel taciz ve çocuk pornografisinin de yayılmasına yol açmıştır. Bu çalışmada, bir sosyal ağda 12 yaşındaki bir kız çocuğu ile paylaşılan penis-el görüntüsünün 2 şüphelisinin dermatolog ve üroloğun katkılarıyla analizi sunulmaktadır. İki zanlının elinde tutulan penislerin fotoğrafları sosyal ağda paylaşılan fotoğrafla karşılaştırıldığında, nevüs, yara izleri ve morfolojik özelliklerin zanlılardan birinin penisiyle uyumlu olduğu belirlendi. Karşılaştırmada aynı zamanda penisin dorsumundaki vasküler yapının benzerliğinden ve farklılığından da yararlanıldı. Sonuç olarak, özellikle şüpheli sayısının arttığı durumlarda, bu tür genital bölge görüntü karşılaştırmaları için bir karşılaştırma prosedürü oluşturulması önerilmiştir.
Çocuklarda Nadir Görülen Schmorl Nodülünün Yanlış Değerlendirilmesinin Yol Açabileceği Hukuki Sonuçlar (Olgu Sunumu)
(2021) Asirdizer, Mahmut; Karabag, Irem Sari; Demir, Uğur; Arslan, Mehmet; Oymak, İsmail
Schmorl nodülü (SN), kıkırdak uç plakanın bozulması ve kıkırdak plakası yoluyla nükleer madde kaybolduktan sonraki dönemde, nükleus pulposusun vertebra gövdesine herniasyonudur. Bir trafik kazasında yaralanan 12 yaşında bir erkek çocuğu hakkındaki bu makalede, travmatik vertebra kompresyon kırığı tanımlanmış ve bu lezyon ile trafik kazası arasında bir nedensellik bağı tespit edilmişti. Beyin cerrahisi, Radyoloji ve Pediatrik Radyoloji ile yapılan değerlendirmeler sonucu bu lezyonun SN olduğu ve trafik kazası ile ilişkili olmadığı sonucuna varıldı. Bu makalede sunulan olgu ile ilgili literatür gözden geçirilerek adli rapor hazırlanırken nedenselliğin tesis edilmesinin önemi ve bu tür durumlarda multidisipliner yaklaşımın gerekliliği vurgulanmıştır.

(Elsevier Sci Ltd, 2018) Asirdizer, Mahmut; Kartal, Erhan; Etli, Yasin; Tatlisumak, Ertugrul; Gumus, Orhan; Hekimoglu, Yavuz; Keskin, Siddik
Suicide is one of the most important public health problems. There was an association between suicide and several factors such as psychiatric diseases and psychological characteristics, somatic illness, cultural, socioeconomic, familial, occupational and individual risk factors. Also, high altitude and climatic factors including high temperature, cloudiness, more sunshine and low rainfalls were defined as some of these risk factors in the literature. In this study, we aimed to investigate correlation between suicide rates and altitudes of all cities in Turkey and between suicide rates and climatic factors including Rainfall Activity Index, Winter Mean Temperatures, Summer Mean Temperatures and Temperature Difference between January and July previously defined by several authors in the broad series in Turkey. In Turkey, 29865 suicidal deaths occurred in 10 years period between 2006 and 2015. Of them, 21020 (70.4%) were males and 8845 (29.6%) were females. In this study, we found that high altitude above 1500 m, winter median temperature lower than - 10 degrees C and hard temperature changes above 25 degrees C between winter and summer of settlements were important factors that affected on female suicide rates appropriate to knowledge which defined in previous studies. In conclusion, we suggested that the associations among suicide rates with altitudes and climate should be studied in wider series obtained from different countries for reaching more reliable results.
The Effect of the Presence or Absence of Skull Fractures on Intracranial Lesion Development in Road Traffic Accidents
(Elsevier Sci Ltd, 2021) Asirdizer, Mahmut; Kartal, Erhan; Ekiz, Aykut; Oymak, Ismail; Tilki, Ismail; Tilki, Gizem Demet Sever
Objective: The aim of this study was to investigate the effect of the presence or absence of skull fractures on the development of intracranial lesions in cases of head trauma associated with traffic accidents. Materials and methods: A retrospective review was made of the medico-legal reports of 774 cases with injuries sustained in a traffic accident and which applied for expert examination as forensic cases at the Department of Forensic Medicine of our University between 1 January 2014 and 31 December 2019. A total of 162 cases (20.1%) were identified which were radiologically diagnosed with at least one skull fracture or intracranial lesion. These cases were evaluated in terms of age, gender, type of accident, and localization of skull fractures and/or intracranial lesions, and they were compared statistically to determine whether the presence or absence of skull fractures affected the development of intracranial lesions. Results: The 162 cases evaluated comprised 120 males and 42 females with a mean age of 25.1 +/- 16.4 years. Intracranial lesions were accompanied by skull fractures in 77 cases, skull fracture alone was determined in 18 cases, and intracranial lesion alone in 67 cases. Skull fractures were mostly (64.5%) seen in the 1-20 years age group, and the intracranial lesions (90%) were mostly seen in the >= 41 years age group. Linear and diastatic fracture rates were highest in the temporal and frontal regions. The intracranial lesion/case ratio was 1.5/1 in cases without skull fracture, and 1.2/1 in cases with skull fracture. Conclusion: The results of this study showed that the rate of linear or diastatic fractures was higher in females, which was associated with skull thickness. Skull fractures were found to occur most between the ages of 1 and 20 years, and the presence of skull fractures was determined to reduce the incidence of intracranial lesions by decreasing intracranial pressure.

(Saudi Med J, 2017) Tatlisumak, Ertugrul; Asirdizer, Mahmut; Bora, Aydin; Hekimoglu, Yavuz; Etli, Yasin; Gumus, Orhan; Keskin, Siddik
Objectives: To define the dimensions of the frontal sinus in groups standardized for age and gender and to discuss the reasons and the effects of the variations. Methods: Frontal sinus measurements were obtained from paranasal CT scans of 180 males and 180 females in the Radiology Department of Dursun Odabas Medical Center of Yuzuncu Yil University, Van, which is located in Eastern Turkey, between February and March 2016. The width and height of sinuses were measured on a coronal plane, and the anteroposterior length was measured on an axial plane. Volumes were calculated using the Hospital Information Management Systems and Image Archiving and Management System program. The Statistical Package of the Social Science version 13 was used for statistical analyses. Results: We determined differences in the frontal sinus measurements of different age groups in a Turkish adult population. Frontal sinus dimensions were usually higher in females and lower in males after 40-49 years of age than their younger counterparts, but the measurements were lower in females and higher in males in 70 <= years of age group than 60-69 years of age. Left frontal sinus was dominant in young age groups but right frontal sinus was dominant in groups 40-49 years of age or older. Conclusion: We observed crossing of the measurements between the different age groups, which we could not find clear explanations. The results of such studies may affect forensic identification from frontal sinus measurements.
The Evaluation of Blood Ethyl Alcohol Levels of Drivers Involved in Traffic Accidents
(Nobel Ilac, 2016) Asirdizer, Mahmut; Yilmaz, Murat; Aker, Rezzan Gulhan; Kucukibrahimoglu, E. Esra; Ates, Ismail; Ince, C. Haluk
Objective: We aimed to evaluate blood alcohol concentrations (BAC) of drivers involved in traffic accidents, to define procedures of blood sampling for BAC analysis and legal sanctions. Material and Method: In 2011 blood samples from 2251 drivers sent to the Chemistry Department of the Council of Forensic Medicine for alcohol determination were analyzed by dual column head-space/gas chromatography flame-ionisation detector (HS/GC-FID). BAC levels above 10 mg/dl were back-extrapolated to the time of crime. Rate of reduction was accepted 15 mg/dl/hr and BAC effects on safe driving skills were discussed. Results: Ethanol was present in 19.4% of drivers. BAC was above 100 mg/dl in more than half of the cases (56.5-64.5%) and was above the allowed level in traffic (50mg/dl) in the majority (78.1-89%). In contravention of legislation, blood sampling was delayed more than two hours following traffic accidents and this created discrepancies in BAC level calculations. Conclusion: Accurate results can be obtained with timely and properly taken blood samples. Health care workers may face serious legal sanctions due to damages that may arise because of blood samples collected contrary to the procedure. An important part of traffic accidents can be prevented with reduction of the allowed BAC in traffic to 30 mg/dl.

(int Scientific information, inc, 2016) Gokalp, Mehmet Ata; Hekimoglu, Yavuz; Gozen, Abdurrahim; Guner, Savas; Asirdizer, Mahmut
Background: Lower limb and pelvic injuries and fractures occur at a very high incidence in motor vehicle accidents. In this study, the characteristics (e.g., body side, bone location, and fracture severity) of lower limb and pelvic fractures that occurred during front-impact collisions were correlated with the injured patients' sex, age, and position in the vehicle. Material/ Methods: We retrospectively evaluated 191 patients (136 males, 55 females) who were injured in motor vehicle accidents, specifically in frontal collisions. Results: This study revealed that most of lower limb and pelvic fractures occurred in males (71.2%; p=. 000), 19-36 years old (55.5%; p=. 000), small vehicles (86.4%; p=. 000), and rear seat passengers (49.2%; p=. 000). Fractures most commonly occurred in the left side of the body (46.6%; p=. 000) and upper legs (37.7%; p=. 000). Severity scores were higher (2.76) in males than females (2.07). No statistically significant was found in severity scores of patients and other personal characteristics and fracture features of patients with lower limb and pelvic fractures who were injured in a vehicle during front-impact collisions (p> 0.05). Conclusions: The results of this study will be useful for the automobile industry, forensics and criminal scientists, and for trauma research studies.

Investigation of Effective Factors on Traumatic Amputations Due To Road Traffic Accidents
(Elsevier Sci Ltd, 2022) Asirdizer, Mahmut; Hekimoglu, Yavuz; Keskin, Siddik
Aim: To determine factors associated with the locations, types and levels of traumatic limb amputations caused by road traffic accidents. Materials and Methods: The files sent by the courts to the expert committee chaired by the authors for the determination of applicants' disability rate over the 10-year period between 2011 and 2020 were examined retrospectively. Results: Of the 27 cases with traumatic amputations caused by road traffic accidents, 63% of them were male and the mean age of the cases was 29.0 +/- 20.0 years. The cases comprised 12 passengers, 10 pedestrians, and 5 drivers. Of all, 66.7% of the amputations were caused by automobile accidents, 59.3% of them were in lower limbs, 51.9% of them were on the right side, and most of them occurred below the elbow/knee levels. Amputations occurred more frequently in lower limbs that are contralateral to the side of the traffic flow, in drivers, and in front seat passengers. Conclusion: The findings in this preliminary study need to be confirmed in studies to be conducted in larger series. The findings of these studies will shed light on technological developments that can be used in the prevention of serious injuries that lead to post-accident traumatic amputations.

An Investigation of the Effect of the Covid-19 (sars-Cov Pandemic on Occupational Accidents (tokat-Turkey)
(Routledge Journals, Taylor & Francis Ltd, 2023) Demir, Ugur; Asirdizer, Mahmut; Kartal, Erhan; Etli, Yasin; Hekimoglu, Yavuz
The aims of this study were to compare the incidence of occupational accidents during one-year periods of the COVID-19 Pandemic and before the COVID-19 Pandemic, and to determine in which sectors occupational accidents occurred and what types of injuries were sustained in the population of Tokat, Turkey. A retrospective review was made of the records of Tokat State Hospital of patients injured in occupational accidents between 12.03.2019 and 11.03.2021. The patients injured in occupational accidents were classified according to age, gender, sector, accident type, trauma localization and type, time of the accident, and outcome of the injuries. Of 608 patients injured in occupational accidents, 384 (63.2%) were injured in the period before the pandemic and 224 (36.8%) were injured in the period during the pandemic (p < 0.001). Most work-related injuries occurred in the industry sector (n = 287; 47.2%; p < 0.001). Occupational accidents increased in the service sector (p < 0.001), but decreased in other sectors. The increase in occupational accidents in the health sector (p < 0.001) and transportation sector (p < 0.05) within the service sector caused a general increase despite the decrease in other service sectors (p > 0.05). In current study, the increase in the number of injuries in the transportation sector due to the increase of motor courier accidents, in health sector, and in pandemic quarantines were remarkable. It was evaluated that this narrow-scoped study pioneered comprehensive studies on the measures that can be taken to prevent occupational accidents in such pandemics in the future.
The Investigation of the Impacts of Major Disasters, on the Basis of the Van Earthquake (October 23, 2011, Turkey), on the Profile of the Injuries Due To Occupational Accidents
(Elsevier Sci Ltd, 2015) Hekimoglu, Yavuz; Dursun, Recep; Karadas, Sevdegul; Asirdizer, Mahmut
The purpose of this study is to identify the impacts of major disasters, on the basis of the Van earthquake (October 23, 2011, Turkey), on the profile of the injuries due to occupational accidents. In this study, we evaluated 245 patients of occupational accidents who were admitted to emergency services of Van city hospitals in the 1-year periods including pre-earthquake and post-earthquake. We determined that there was a 63.4% (P < 0.05) increase in work-related accidents in the post-earthquake period compared to the pre-earthquake period. Also, injuries due to occupational accidents increased 211% (P < 0.05) in the construction industry, the rate of injuries due to falls from height increased 168% (P < 0.05), and the rate of traumas to the head and upper limbs increased 200% (P < 0.05) and 130% (P < 0.05), respectively, in the post-earthquake period compared to the pre-earthquake period. We determined that the ignoring of measures for occupational health and safety by employers and employees during conducted rapid construction activities and post-earthquake restoration works in order to remove the effects of the earthquake increased the number of work accidents. In this study, the impact of disasters such as earthquakes on the accidents at work was evaluated as we have not seen in literature. This study emphasizes that governments should make regulations and process relating to the post-disaster business before the emergence of disaster by taking into account factors that may increase their work-related accidents.

Non-Traumatic Ecchymoses: a Literature Review From a Medico-Legal Perspective
(Elsevier Sci Ltd, 2023) Asirdizer, Mahmut; Besik, Elif Zeynep; Kartal, Erhan
Ecchymosis, as a general term, refers to discoloration of the skin due to the presence of extravasated blood into the dermis and/or subcutaneous tissue. However, it can occasionally be observed without any trauma, as a symptom of disease, a clinical condition, or even during the course of treating a disease. It is extremely important that these non-traumatic lesions are known and recognized and can be distinguished from traumatic ecchymoses by both clinicians and forensic scientists.This review of the literature includes detailed descriptions of non-traumatic periorbital ecchymosis, Slapped Cheek Syndrome, Cullen's Sign, Grey Turner's Sign, Stabler's Sign, Ransohoff Sign, Bryant's Sign, postsacral ecchymosis, perianal ecchymosis, Fox's Sign, other lower leg ecchymosis, and ecchymosis on various body regions.In this article, it is emphasized that failure to correctly identify these findings may subject practitioners to malpractice lawsuits, and failure to correctly identify findings by forensic experts may result in unjust legal judgments against people or loss of rights. It is also this review encourages accurate diagnosis of non-traumatic ecchymoses.
The Possible Effects of Altitude and Climate on the Development of the Frontal Sinus in Adults
(Soc Chilena Anatomia, 2017) Asirdizer, Mahmut; Tatlisumak, Ertugrul; Bora, Aydin; Tarhan, Serdar; Ovali, Gulgun Yilmaz; Hekimoglu, Yavuz; Keskin, Siddik
Climatic and altitude features of living region may affect human body. Many changes in several tissues and organs and several health problems due to climatic and altitude effects were defined in the literature. However, there were limited number of studies which evaluated correlation between development of frontal sinus and climatic/altitude effect. In this study, widths, heights, AP lengths and volumes of frontal sinus were compared by Paranasal CT scans in populations living in Van which has colder climate and higher altitude and Manisa which has milder climate and lower altitude. It was found that widths, antero-posterior lengths and volumes of frontal sinus were higher in populations living in colder climate and higher altitude according to populations living in milder climate and lower altitude. Heights of frontal sinuses were on the contrary of this. These results were found appropriate to increasing of cephalic index in cold climate according to Allen's Rule. We suggest that larger population study should be made with peoples having the same or similar race and genetic structure in different climate and altitude regions and the proportional comparison of frontal sinus measurements with cephalic index should be considered in future studies.
The Postman Always Rings Twice Two Cases of Shotgun Deaths Associated With an Unconventional Home Security Alarm System
(Lippincott Williams & Wilkins, 2014) Asirdizer, Mahmut; Turkmen, Nursel; Akan, Okan; Yavuz, Mehmet Sunay
Injury and death cases caused by booby traps are not common in forensic medicine practice. Besides, installation of booby traps including firearms is generally for suicidal and rarely for homicidal purposes. Although few patents were described about home security alarm system that were created by firearms in the United States, 1 sample of injury with a similar unconventional mechanism of home safety system was reported by Asirdizer and Yavuz in 2009. In the published case report, the story of an electrical technician who was invited to a summer house by the homeowner to check the home security alarm system was reported. In the so-called report, he was stated to be injured by the shotgun attached to the unconventional home security alarm system while checking the system. As a result, the homeowner was convicted of a possible intent to cause a life-threatening injury to the technician. The so-called homeowner and his wife died by the same shotgun attached to the same unconventional home security alarm system 4 years on from the first event. In the present case report, we have aimed to present the findings of the crime scene and the autopsies of these unusual 2 deaths and to discuss individual and legal factors in paving the way for the deaths of 2 people.
Sex Estimation From Measurements of the Mastoid Triangle and Volume of the Mastoid Air Cell System Using Classical and Machine Learning Methods
(Lippincott Williams & Wilkins, 2024) Sasani, Hadi; Etli, Yasin; Tastekin, Burak; Hekimoglu, Yavuz; Keskin, Siddik; Asirdizer, Mahmut
Previous studies on the sexual dimorphism of the mastoid triangle have typically focused on linear and area measurements. No studies in the literature have used mastoid air cell system volume measurements for direct anthropological or forensic sex determination. The aims of this study were to investigate the applicability of mastoid air cell system volume measurements and mastoid triangle measurements separately and combined for sex estimation, and to determine the accuracy of sex estimation rates using machine learning algorithms and discriminant function analysis of these data. On 200 computed tomography images, the distances constituting the edges of the mastoid triangle were measured, and the area was calculated using these measurements. A region-growing algorithm was used to determine the volume of the mastoid air cell system. The univariate sex determination accuracy was calculated for all parameters. Stepwise discriminant function analysis was performed for sex estimation. Multiple machine learning methods have also been used. All measurements of the mastoid triangle and volumes of the mastoid air cell system were higher in males than in females. The accurate sex estimation rate was determined to be 79.5% using stepwise discriminant function analysis and 88.5% using machine learning methods.
