ObjectivesTo compare hearing outcome and surgical complications between endoscopic classic and reversal stapedotomies.Patients and methodsA prospective single blinded randomized clinical study carried out on 60 patients with otosclerosis who were randomized into two groups; each containing 30 patients. Patients in group 1 underwent endoscopic classic stapedotomy. Patients in group 2 underwent endoscopic reversal stapedotomy. Both groups were compared as regards hearing outcome and surgical complications.ResultsThe difference in the hearing outcome between the two groups was statistically non-significant. Post-operative closure of the air bone gap (ABG) within 10 dB was attained in 76.67% and 80% of patients in groups 1 and 2, respectively. The differences in the surgical complications between the two studied groups were statistically non-significant.ConclusionEndoscopic classic and reversal stapedotomies are comparable to each other as regards hearing outcome and surgical complications. The authors recommend further studies with relatively larger sample size.
