Double Layer Crescent Graft Technique for Endoscopic Tympanoplasty
(Royal Belgian Soc Ear, Nose, Throat, Head & Neck Surgery, 2019) Aslan, M.; Duzenli, U.
Objectives: The main aim of this study was to present the surgical and functional outcomes of tympanoplasty performed using the crescent graft technique. Methodology: In this research, we used an underlay crescent cartilage-perichondrium composite graft and overlay perichondrium graft to repair tympanic membrane perforation. Pre-operative and post-operative tympanic membrane examinations and hearing evaluations were performed. Results: A total of 155 patients were included in this retrospective study. The pre-operative hearing threshold was 12.95 +/- 3.85 dB and the post-operative threshold 5.7 +/- 4.1 dB. The improvement was significant (p<0.05). Reperforation was observed in nine patients, graft lateralization in five patients, and graft retraction in four patients at the 1-year follow-up. Conclusion: Double-layer crescent graft tympanoplasty yielded successful functional and hearing outcomes.
Manubrio-Incudo for Reconstruction of Austin-Kartush Type B Ossicular Defects
(Cambridge Univ Press, 2019) Duzenli, U.; Kiroglu, A. F.
Objective Manubrio-incudo-stapedioplasty functional outcomes were compared to those of other methods for reconstructing Austin-Kartush type B ossicular defects. Methods Forty-two patients underwent Austin-Kartush type B ossicular defect reconstruction using: manubrio-incudo-stapedioplasty (13 patients), an autologous incus (19 patients) or a titanium ossicular replacement prosthesis (10 patients). For manubrio-incudo-stapedioplasty reconstruction, the malleus head was removed, the manubrium was relocated posteriorly and the incus short process was placed on the mobile footplate. The manubrium was placed on the incus body groove and bone cement was applied to stabilise the manubrium-incus junction. Pre- and post-operative hearing thresholds were assessed. Results The air-bone gap decreased from 25.9 +/- 6.0 dB to 12.3 +/- 5.0 dB (p < 0.05) in the manubrio-incudo-stapedioplasty group. The hearing gain was 13.6 +/- 5.2 dB for manubrio-incudo-stapedioplasty, 3.4 +/- 14.2 dB with the autologous incus, and 3.3 +/- 11.07 dB with the titanium ossicular replacement prosthesis. Hearing improvement was greater for manubrio-incudo-stapedioplasty compared to the other reconstruction methods (p < 0.05). Conclusion Manubrio-incudo-stapedioplasty resulted in satisfactory hearing outcomes in patients with Austin-Kartush type B ossicular defects. This technique can be considered a stable, inexpensive and effective method to reconstruct Austin-Kartush type B ossicular defects.

The Relationship Between the Abo Blood Group and Tumor Diameters in Patients With Carotid Body Tumors
(Yuzuncu Yil Universitesi Tip Fakultesi, 2018) Bozan, N.; Duzenli, U.; Arı, M.; Turan, M.; Kıroglu, A.F.; Aslan, M.
Several studies have assessed the association between blood group of ABO and many cancer types. Nevertheless, there was no data regarding the connection between blood group of ABO and tumor diameters in carotid body tumors (CBTs) patients. The purpose of our study was to analyse possible association between tumor diameters and gender, ABO blood group in CBTs patients compared to healthy controls. The demographic and laboratory data of 65 CBTs patients (57 females and 8 males) who underwent surgical intervention and 65 healthy controls (52 females and 13 males) were retrospectively analyzed. The mean age of CBTs patients was 51.81±9.82 years, and the mean age of the healthy subjects was 52.72±8.50 years. There were no statistically significant difference between two groups with regard to age and gender. The mean of tumor diameters was 3.72±1.50 cm (range=1-8 cm). There was no statistically significant difference between study groups according to AB0 blood group (p=0.87). The females/males ratio of patients was 57/8. The mean tumor diameters of females was 3.57±1.34 cm and the mean tumor diameters of males was 4.77±2.16 cm; the difference was statistically significant (p=0.03). There was a positive correlation between male gender and the tumor diameters (r=0.23, p=0.03). This is the first report investigating association between the tumor diameters and AB0 blood group in CBTs. Although CBTs were shown higher in females, tumor diameters were found significantly higher in males tha n females. However, we did not determine any association between AB0 blood group and tumor diameters. © 2018, Yuzuncu Yil Universitesi Tip Fakultesi. All rights reserved.
Sixteen Years of Experience With Otosclerosis Revision Surgery: Report of 105 Cases
(Royal Belgian Soc Ear, Nose, Throat, Head & Neck Surgery, 2019) Duzenli, U.; Cath, T.; Gur, H.; Ceylan, M. E.; Olgun, L.
Objectives: Otosclerosis is a progressive disease of the bony labyrinth characterised by bone formation, which can cause conductive, mixed and, rarely, sensorineural hearing loss. Surgery on the stapes footplate can be successful for treating conductive hearing loss. However, complaints of new issues after surgery may prompt revision surgery. This report presents the results of revision stapes surgeries. Methodology: Study population consisted of patients who had undergone revision stapes surgery. Indications, findings during surgery, and preoperative and post-operative audiological data were recorded. Success rates of the surgeries were evaluated statistically. Results: Total of 105 cases was included in this study, and the major indication for surgery was hearing loss. Mean preoperative hearing threshold of the patients was 57.1 dB and the mean air-bone gap (ABG) was 27.4 dB; the respective postoperative values were 49.7 and 19.2 dB, respectively (p<0.05). Most common intraoperative pathologies were prosthesis-related problems and fibrotic bands/adhesion in the middle ear. Conclusions: Revision stapes surgery can yield successful results, especially with regard to persistent or late-onset conductive hearing loss. Likelihood of hearing gain may be decreased after repeated surgeries.
