Abstract
PURPOSE: 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 Selcuk 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.
