Unlabelled: Stapes surgery is one of the approaches indicated to treat conductive hearing loss secondary to otosclerosis. The procedures requires skill and experience from the surgeon and is part of medical residency training., Aims: To assess which type of prosthesis (Teflon or metal/steel) presents the best results in surgeries performed by residents and the incidence of complications., Materials and Methods: we retrospectively assessed 189 interventions that counted on the active participation of resident physicians, and we compared the two types of prosthesis used. Audiometric results were analyzed following the guidelines from the Committee on Hearing and Equilibrium and also according to the Amsterdam Hearing Evaluation Plots., Results: Bone-air gap reduced in an average value of 21.90 dB (p<0.05) after the surgery in the group that received the Teflon prosthesis and 21.37 dB (p<0.05) in the group that received the mixed prosthesis, and gain in SRI was of 22.33 and 26.10 dB (p<0.05), and the air-bone gap was below 20 dB in 80.6% and 85.04%, respectively., Conclusions: We did not see differences in the audiometry and in the incidence of complications when we compared the type of prosthesis used. We believe it is valid to continue teaching this procedure in medical residency training programs, regardless of the type of prosthesis.

Unlabelled: Surgery of the stapedius remains the established treatment for otosclerosis. Recent publications have showed that success in surgeries done by residents have decreased and hearing results are worse than those obtained by experienced otologic surgeons., Aim: To evaluate the experience of the otorhinolaryngology unit, Parana University, relative to stapes surgery done in the residency training program., Material and Method: A retrospective study of 114 stapes surgeries done in the past 9 years in 96 patients. Audiometric results were analysed according to the Committee on Hearing and Equilibrium guidelines and the Amsterdam Hearing Evaluation Plots. The improvement of the airway postoperative gap and thresholds were taken into account., Results: 96 patients were included, most of them female adults (67.7%) and white (93.7%). Stapedectomy was done in 50.9% of cases, mostly under local anesthesia and sedation (96.5%), using mostly the Teflon prosthesis (37.7%). The surgical success rate was 50.88%, there was an 11.4% complication rate., Conclusion: Postoperative hearing gains considered as surgical success were inferior to published results in the literature, done by experienced surgeons.

Unlabelled: The number of patients with stapes otosclerosis compared to the number of otorhinolaryngologists has declined over the past several years. As a result a controversy has arisen in the literature, whether or not stapes surgery should be included in residency programs., Aim: the objective of the present study is to evaluate the results and complications of estapedotomies performed by residents between January, 1997 and January, 2000, and consequently study the feasibility of including estapedotomies in residency programs. STUD DESIGN: retrospective review of prospectively collected audiometric data., Materials and Methods: fifty charts of patients that were submitted to a total of 51 primary stapedotomies were reviewed mainly for complications and audiological results., Results: there was closure of the air-bone gap within 10 dB HL in 70.5% of ears and closure to within 20 dB HL in 86.3% of ears. There was one ear with total hearing loss (2%)., Conclusion: From the results and complications seen in the present study, and analyzing papers from the literature, it is possible to conclude that stapedotomy is a procedure that can be included in residency programs, if there are surgical cases for the residents.
