Abstract
BackgroundStapedotomy is being performed endoscopically for otosclerosis in Sudan since 2011 with increasing number of patients. This prospective hospital-based study from Nov 2016 to Nov 2020 states the clinic-demographic features of otosclerosis; it describes this surgical technique and hearing outcome following endoscopic stapedotomy.ResultsTotal number included in the study was 91 patients. Females were 48, and males were 43 with a female to male ratio of 1.1:1. Age ranged from 19 years to 52 with a mean age of 30.6± 7 SD years. The main symptom was decreased hearing in all patients (100%); in 82 patients (90%), it was bilateral, followed by tinnitus in 80 patients (88%) while two patients (2.2%) had vertigo. Family history was stated by 2 patients (2.2%) only. Audiological assessment by pure tone audiogram (PTA) for each ear (total of 182) revealed that conductive hearing loss (CHL) is the commonest type of hearing loss in 148 ears (81.3%), mixed type in 30 ears (16.5%), while 4 ears (2.2%) were normal.Endoscopic stapedotomy was performed for 74 patients; this technique was safe; few complications were managed successfully: one gusher and one revision, with no facial nerve injury. Majority of complications happened during the first year. Mean air bone gap (ABG) gain was 23.3± 7.2 dB, air conduction (AC) gain was 18.3 ± 8 dB, and Carhart notch disappeared in 79.5%.ConclusionsEndoscopic stapedotomy is a safe and effective procedure with a steep learning curve and a satisfactory hearing outcome. The air bone gap (ABG) gain was comparable to international studies.
Highlights
Stapedotomy is being performed endoscopically for otosclerosis in Sudan since 2011 with increasing number of patients
This study aims at addressing the clinicodemographic features of otosclerosis in the studied group of patients; it describes the technique of endoscopic stapedotomy and reviews the audiological outcome of this technique
Endoscopic stapedotomy was performed for 74 patients, as a primary procedure for 73 patients (98.6%) and as revision for 1 patient (1.4%)
Summary
Stapedotomy is being performed endoscopically for otosclerosis in Sudan since 2011 with increasing number of patients. This prospective hospital-based study from Nov 2016 to Nov 2020 states the clinicdemographic features of otosclerosis; it describes this surgical technique and hearing outcome following endoscopic stapedotomy. The clinical form of otosclerosis is more common in women than in men; interestingly, in the histological form of the disease, the ratio between women and men was found to be 1:1 [7]. Otosclerosis is one of the most common causes of adult-onset hearing loss in the Caucasian population, where it has a prevalence of Abdullah et al The Egyptian Journal of Otolaryngology (2021) 37:81
