    Are long-term auditory results following ossiculoplasty with bone cement as successful as early-middle period results?
    (W B Saunders Co-Elsevier Inc, 2020) Kalcioglu, M. Tayyar; Yalcin, Muhammed Zeki; Kilic, Osman; Tuysuz, Ozan; Tan, Mehmet; Ozdamar, Osman Ilkay
    Purpose: Bone-cement (BC) ossiculoplasty is one of the options to solve ossicular chain problems. Many authors reported successful results in the early or mid-follow-up period; however, there is no long-term result in the literature. We aim to evaluate long term results of BC ossiculoplasty. Materials and methods: Forty-eight patients who underwent BC ossiculoplasty as incudostapedial re-bridging by the same surgeon were invited to evaluation. Postoperative otomicroscopic examination was performed. Preoperative and post-operative audiological results after longer follow up and graft success rate were noted. Results: Fourteen patients came for control examination. The follow-up period was between 87 and 135 months (mean 102 months). None of the patients had graft failure. Ten patients had early postoperative follow-up results (between 10 and 52; mean 24 months). In the comparison of preoperative and early postoperative air-bone gap, there were significant differences in all frequencies while the comparison of preoperative and long-term postoperative results showed a significant difference only in 250 and 500 Hz. Early postoperative results were better than late with significant difference only in the 2000 and 4000 Hz. Conclusions: As reported by many studies, bone cement application provides a significant auditory improvement in the early postoperative period. The results of the present study showed that this early auditory success may decrease over time with a long-term follow-up. Further studies should be conducted with larger patient groups to clarify the long-term benefits of this treatment and possible causes for its deterioration.

    Can artificial ıntelligence detect the anti-aging effect of rhinoplasty?
    (Medical Journal Sweden Ab, 2025) Yalcin, Muhammed Zeki; Toplu, Yuksel; Kurt, Osman
    Background: The quest for eternal youth has been a common theme in many cultures for centuries. While we have yet to discover a way to preserve youth eternally, we have made significant progress in understanding the aging process and in developing pharmaceuticals, surgical techniques, and technologies. In addition to rhinoplasty's facial beautification effect, we investigated whether it had a facial anti-aging effect using an artificial intelligence (AI)-based program. We also examined the correlation between patient satisfaction and the anti-aging effect of rhinoplasty. Methods: This study included 244 patients who underwent functional septorhinoplasty (FSRP) between postoperative photographs in our archive were evaluated using an AI-based age analysis program. In addition, the participants evaluated preoperative and postoperative nose satisfaction with the FACE-Q survey in the postoperative period. Results: One hundred two males (41.8%) and 142 females (58.2%) were included in the study. The mean preoperative age determined by the program was 25.9 +/- 6.1, and the mean postoperative age was 25.7 +/- 5.8. Despite the mean follow-up period of the patients was 25.3 +/- 8.7 months, our study showed no significant difference between the mean preoperative and postoperative ages. The mean general satisfaction of the patients increased postoperatively. Conclusion: Despite the average follow-up period, the absence of a significant difference between preoperative and postoperative perceived mean age may be interpreted as a possible anti-aging effect of rhinoplasty. This effect was more prominent in older patients and in women.

    Does Inferior Oblique Muscle Overaction Affect Ocular Vestibular Evoked Myogenic Potentials?
    (Pera Yayincilik Hizmetleri, 2023) Demir, Ismail; Yalcin, Muhammed Zeki; Cengiz, Deniz Ugur; Aydin, Sukru; Cankaya, Cem; Tekin, Ahmet Mahmut
    Objectives: Inferior oblique muscle overaction (IOOA) is a common ocular motility disorder. Ocular Vestibular Evoked Myogenic Potentials (oVEMP) are tests that evaluate the reflex pathway between the utricular macula and the inferior oblique muscle to detect vestibular diseases. Our study is of great importance as it is the first study in the literature to evaluate the effect of inferior oblique muscle overaction on oVEMP parameters. Methods: Thirty-five patients with unilateral inferior oblique muscle overaction (IOOA group) and 18 healthy volunteers without any neurological or vestibulocochlear disease were included in this study. All patients and healthy volunteers were evaluated with oVEMP. Results: No statistically significant difference was found between the n1 latency, p1 latency, n1-p1 latency measurement values of the participants included in the study (p>0.05). A statistically significant difference was found between the n1-p1 amplitude measurement values of the participants in patient groups (non-squint eyes, squint eyes) and control groups (p-value was 0.038). Conclusion: In IOOA patients, vestibulo-ocular reflex pathway may be affected, vestibular symptoms may develop thus o-VEMP responses may be affected. A careful anamnesis should be taken in IOOA patients, and it should be kept in mind that n1-p1 amplitudes and asymmetries may be significantly higher when o-VEMP is performed

    Is it taboo to elevate the tympanomeatal flap? Outcomes of endoscopic transcanal type 1 cartilage tympanoplasty with double-layer crescent graft technique
    (Aves, 2021) Aslan, Mehmet; Cicek, Mehmet Turan; Tan, Mehmet; Yalcin, Muhammed Zeki
    Objective: In this study, we aimed to examine the surgical and functional results of tympanoplasty performed with a double-layer crescent graft technique. We also aimed to investigate the anatomical and functional results of type 1 tympanoplasty with a large series without elevation of the tympanomeatal flap. Methods: The anatomical and functional results of 245 patients treated with endoscopic type 1 tympanoplasty by double-layer crescent graft between January 2015 and January 2019 were retrospectively evaluated in terms of age, sex, tympanic membrane perforation size, complication, functional hearing before and after surgery, and duration of the operation. Results: The participant cohort was 59.2% women (n=145) and 40.8% men (n=100), and the average age was 30.8286 +/- 10.29897 years (minimum 13, maximum 56). Overall, the anatomical success rate was 91.83%; in patients with medium tympanic membrane perforation of 25%-75%, it was 94.9%; and in patients with large perforation of > 75%, it was 88%. When complications were examined, the rates of graft perforation, lateralization, and retraction rates were 8.1%, 8.1%, and 3.6%, respectively. The average operation time was 33.0449 +/- 3.02348 minutes. Conclusion: Endoscopic double-layer crescent graft tympanoplasty is a successful method to ensure anatomical and physiological results in medium and large tympanic membrane perforations. In addition, it was observed that the operation could be performed with a shorter surgical time without elevating the tympanomeatal flap, and its anatomical and functional results were successful.
