Anterior Clinoid Process in Chiari Malformation Type 2: Measurements, Classifications, Pneumatization Ratio, and Clinical Relevance
(Lippincott Williams and Wilkins, 2025) Karaaslanli, A.; Aslanoǧlu, B.; Erdem, M.Z.; Yalinkiliç, A.; Beger, B.; Şerifoǧlu, L.; Beger, O.
Objective: To reveal differences in morphologies of the anterior clinoid process (ACP) in patients with Chiari malformation type 2 (CMT2) by comparing normal subjects. Methods: Computed tomography slices of 50 CMT2 (sex: 21 females and 29 males, and mean age: 9.04±5.85 y) and 50 controls (sex: 21 females and 29 males, and mean age: 8.69±5.34 y) were included in the work. The angle (AACP), width (WACP), and length (LACP) of ACP, the width (WOS), and length (LOS) of the optic strut (OS), and the distance (DisOSACP) of OS to ACP were measured. Results: Patients with CMT2 had smaller LACP (P<0.001) and DisOSACP (P=0.007) than controls, but similar WACP, AACP, LOS, and WOS (P>0.05). ACP pneumatization was observed in 10% of CMT2s (10 ACPs) and 12% of controls (12 ACPs). CMT2 did not correlate with the pneumatization (P=0.651). Three configurations regarding ACP pneumatization were detected in CMT2 (types 0: 90%, 1: 8%, and 2: 2%) and controls (types 0: 89%, 1: 9%, and 2: 2%). Four types related to OS position were detected in CMT2 (types B: 5%, C: 30%, D: 51%, and E: 14%) and controls (types B: 3%, C: 15%, D: 69%, and E: 13%). This classification was affected by CMT2 (P=0.041). Conclusions: CMT2s have more anteriorly located OS, and shorter ACP by comparison controls. There is no association between CMT2 and the incidence of ACP pneumatization. Copyright © 2025 Mutaz B. Habal, MD. Unauthorized reproduction of this article is prohibited.
Morphometric Properties of the Tensor Fascia Lata Muscle in Human Foetuses
(Via Medica, 2018) Beger, O.; Koc, T.; Beger, B.; Uzmansel, D.; Kurtoglu, Z.
Background: In neonatal and early childhood surgeries such as meningomyelocele repairs, closing deep wounds and oncological treatment, tensor fasciae lata (TFL) flaps are used. However, there are not enough data about structural properties of TFL in foetuses, which can be considered as the closest to neonates in terms of sampling. This study's main objective is to gather data about morphological structures of TFL in human foetuses to be used in newborn surgery. Materials and methods: Fifty formalin-fixed foetuses (24 male, 26 female) with gestational age ranging from 18 to 30 weeks (mean 22.94 +/- 3.23 weeks) were included in the study. TFL samples were obtained by bilateral dissection and then surface area, width and length parameters were recorded. Digital callipers were used for length and width measurements whereas surface area was calculated using digital image analysis software. Results: No statistically significant differences were found in terms of numerical value of parameters between sides and sexes (p > 0.05). Linear functions for TFL surface area, width, anterior and posterior margin lengths were calculated as y = -225.652 + 14.417 x age (weeks), y = -5.571 + 0.595 x age (weeks), y = -4.276 + 0.909 x age (weeks), and y = -4.468 + 0.779 x age (weeks), respectively. Conclusions: Linear functions for TFL surface area, width and lengths can be used in designing TFL flap dimensions in newborn surgery. In addition, using those described linear functions can also be beneficial in prediction of TFL flap dimensions in autopsy studies.
Pediatric Tracheotomy: Indications, Timing, and Clinical Outcomes
(Yuzuncu Yil University Tip Fakultesi, 2026) Yalınkılıç, A.; Yürektürk, E.; Aydın, M.; Beǧer, B.; Ağırbaş, S.; Kaçmaz, F.; Beger, O.
This study aimed to evaluate the indications, timing, and clinical outcomes of pediatric tracheotomy cases managed at a single tertiary center over a 13-year period. A retrospective review was conducted of 110 pediatric patients (1 day–18 years) who underwent tracheotomy between 2010 and 2023. Demographic data, indications, tracheotomy timing (TIT), duration of hospitalization, complications, and mortality were analyzed. Statistical analyses included Mann-Whitney U, Kruskal-Wallis, and chi-square tests, with p<0.05 considered significant. Among 110 pediatric patients, 66 were male, and 44 were female. The most common indication for tracheotomy was prolonged mechanical ventilation (80.9%), followed by airway obstruction (19.1%), which was more frequent in newborns (p=0.004). Hospital stay duration and tracheotomy timing were significantly shorter in airway obstruction cases than in prolonged ventilation (p<0.001), with significant differences among age groups (p=0.008 and p<0.001). Overall mortality was 31.8%, predominantly among patients with congenital or neurological comorbidities; no statistically significant association was found between mortality and tracheotomy indication (p=0.445). Pediatric tracheotomy remains a safe and effective intervention when performed with appropriate timing and multidisciplinary care. Our study reveals that early tracheotomy does not impact mortality rates; however, it does shorten hospital stay duration and reduce complications. © 2026, Yuzuncu Yil Universitesi Tip Fakultesi.
