Öğe 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 IlkayPurpose: 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.Öğe Does cartilage thickness affect hearing results in real life? Long-term results of cartilage and fascia graft in type 1 tympanoplasty(Wiley, 2019) Kalcioglu, Mahmut Tayyar; Tuysuz, Ozan; Yalcin, Muhammed Zeki; Karatas, Erkan[Abstract Not Available]Öğe 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 MahmutObjectives: 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 performedÖğe 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 ZekiObjective: 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.
