Determination of Endoscopic Stapedotomy Technique and Its Audiological Outcome

Background: Sudan has been performing endoscopic stapedotomy for otosclerosis since 2011, with a growing number of patients. In this prospective hospital-based study, which spans from November 2016 to November 2020, the clinic-demographic characteristics of otosclerosis, as well as the surgical method and hearing result following endoscopic stapedotomy, are discussed.

The total number of patients enrolled in the trial was 91. With a female to male ratio of 1.1:1, females were 48 and males were 43. The participants’ ages ranged from 19 to 52, with a mean age of 30.6 7 SD years. The most common symptom was reduced hearing in all patients (100 percent); it was bilateral in 82 patients (90 percent), followed by tinnitus in 80 patients (88 percent), and vertigo in two patients (2.2 percent). Only two patients (2.2 percent) mentioned their family history. Audiological evaluation by pure tone audiogram (PTA) for each ear (total of 182) found that conductive hearing loss (CHL) was the most prevalent form of hearing loss in 148 ears (81.3%), mixed type in 30 ears (16.5%), and normal in four ears (2.2%).

Endoscopic stapedotomy was performed on 74 patients; it was a safe procedure with only a few complications: one gusher and one revision, and no facial nerve injury. During the first year, the majority of difficulties occurred. The average air bone gap (ABG) increase was 23.3 7.2 decibels, the average air conduction (AC) gain was 18.3 dB, and the Carhart notch vanished in 79.5 percent of the cases.

Conclusions: Endoscopic stapedotomy is a safe and effective treatment with a steep learning curve and a good outcome in terms of hearing. The increase in the air bone gap (ABG) was equivalent to that seen in other research.
