ABSTRACTBackground: Intraoperative and late complications are directly related to the surgical technique performed in otoesclerosis surgery.
Objective: To observe if a significant difference exists in the audiologic results of stapedectomy, conventional stapedotomy and inverse stapedotomy in otosclerosis surgery.
Patients and methods: A comparative study was completed in 100 patients and 96 were included in the study. Audiologic exams were done for control three and six months after surgery. Patients were divided into three groups: Group A with 38 patients with stapedectomy; Group B with 26 patients with conventional stapedotomy and Group C with 32 patients with inverse stapedotomy.
Results: An air bone gap closure of 10 db for Group A was 78.9%, for Group B was 80.7% and for Group C 87.5%. For a closure of 20 db Group A was 84.2%, for Group B 84.6% and for Group C 90.6%. No statistical significance was found for the groups studied (p ‹ 0.05), however, the percentages were a little in favor of the inverse stapedotomy.
Conclusions: The techniques of stapedectomy, conventional stapedotomy and inverse stapedotomy result in favorable audiologic outcomes in otosclerosis surgery. No important comparative results were observed.
