Öğe Comparison of endoscopic and microscopic methods in stapedotomy: a retrospective analysis(Springer, 2023) Celik, Turgut; Erdur, Omer; Gul, Osman; Firat Koca, Cigdem; Colpan, BaharPurpose The goal of the present study was to compare the audiologic results, complications, and advantages/disadvantages of endoscopic and microscopic stapedotomy. Methods Patients who experienced stapedotomy surgery in the Ear Nose Throat Clinic (ENT) of XXXX University Faculty of Medicine between September 2011 and January 2018 were included in the study. The data of all patients were analyzed and divided into two groups. Those who underwent endoscopic stapedotomy were included in group I, and patients who underwent microscopic stapedotomy formed group II. Surgical findings, complications, and operation times were compared for the two groups. Air and bone conduction thresholds were evaluated at the frequencies of 500, 1000, 2000, and 4000 Hz pre- and postoperatively at 1, 3, and 6 months, and the mean (+/- SD) air-bone gap value was recorded. Results While the mean pre- and postoperative air-bone gaps were 34.38 +/- 7.47 dB (23-53 dB) and 9.69 +/- 4.43 dB (0-19 dB), respectively, in group I, 34.32 +/- 7.57 dB (23-6 dB) and 9.62 +/- 4.25 dB (2-23 dB) were the respective means calculated in group II (p < 0.05). When the mean postoperative air-bone gap was compared, there was no statistically significant difference between the two groups (p = 0.774). The mean operative times for groups I and II were 57.22 +/- 4.37 min and 63.70 +/- 7.34 min, respectively (p < 0.001). The requirement for chorda tympani nerve manipulation and scutum curettage was significantly less in group I compared to group II (p = 0.003). Postoperative dysgeusia and postoperative pain were found to be higher in group II than group I, but they were not statistically significant (p > 0.05). Conclusion Endoscopic stapedotomy displayed similar audiological results, shorter operation times, and similar complication rates, as well as being a less invasive surgery, compared to the microscopic approach.Öğe Comparison of endoscopic and microscopic methods in stapedotomy: a retrospective analysis (Jun, 10.1007/s00405-022-07507-3, 2022)(Springer, 2023) Celik, Turgut; Erdur, Omer; Gul, Osman; Koca, Cigdem Firat; Colpan, Bahar[Abstract Not Available]Öğe Endoscopic Management of Maxillary Sinus Schwannoma(Lippincott Williams & Wilkins, 2022) Celik, Turgut; Koca, Cigdem Firat; Aydin, SukruSchwannomas are benign tumors originate from nerve sheath. In this article, the authors aimed to share our experience and review the literature on endonasal endoscopic intervention for a maxillary sinus schwannoma. A 30-year-old Caucasian female patient applying to ophthalmology clinic due to exophthalmos and proptosis in her left eye for the last 6 months. A well-defined mass was detected in left maxillary sinus that was filling and expanding the sinus. Endoscopic biopsy from the patient was reported as ancient schwannoma. The encapsulated mass was completely removed by performing a combined endoscopic medial maxillectomy and Caldwell-Luc procedure under general anesthesia. The authors have been following the patient for 2 years and there was no evidence of recurrence, however, a decrease in the volume of the maxillary sinus occurred, suggesting chronic maxillary atelectasis. In conclusion, schwannoma should be considered in the differential diagnosis of sinonasal masses.Öğe The effect of the severity of COVID-19 on the sequelae of the audiovestibular system(Sage Publications Inc, 2023) Aydin, Sukru; Koca, Cigdem Firat; Celik, Turgut; Kelles, Mehmet; Yasar, Seyma; Oguzturk, SaadetObjectives: The neurotropic and neuroinvasive properties of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) have been described. It remains unknown how SARS-CoV-2 affects the audiovestibular system when it causes mild or severe disease. In this study, the sequelae effect of SARS-CoV-2 on the audiovestibular systems of different patient groups was investigated using objective and subjective test batteries. Methods: In this present study, we evaluated vestibulocochlear functions of patients who previously had Coronavirus Disease-2019 (COVID-19) with pure tone audiometry, ocular vestibular-evoked myogenic potential (o-VEMP), and cervical vestibular-evoked myogenic potential (c-VEMP) tests to identify possible sequelae by comparing them with the control group. Results: We found that the amplitude of p13-n23 was lower in both groups of patients than in the control group (p < 0.001). In the results of the left ear c-VEMP, the amplitude of p13-n23 was statistically different between the outpatient, inpatient, and control groups. The amplitude of p13-n23 was lower in both groups of patients than in the control group (p < 0.001). In the evaluation of the o-VEMP in the left ear, we observed a statistically significant difference in the latency of n10 (p = 0.006) and the amplitude of n10-p15 (p < 0.001) between the groups. The n10 latency was prolonged in both groups of patients compared to the control group and there was no statistically significant difference between groups of patients. Furthermore, the amplitude of n10-p15 was lower in both groups of patients compared to the control group and there were no statistically demonstrable differences between the groups of patients. Conclusions: In conclusion, our results suggest that SARS-CoV-2 may affect the vestibulocochlear system. But we could not find a direct relationship according to the severity of the disease.
