Aim of the study: For surgery of otosclerosis, broughting to the fore interest of crossing informations achieved by using AAO-HNS guidelines for conductive hearing loss and Glasgow Benefit Plot (GBP). Secondary aim: compare stapedotomy with and without veinous interposition. Institutions: Referential otologic center in semi-country-side general hospital and private institution in urban zone. Materials and method: retrospective bi-centric study comparing 129 cases of primary surgery for otosclerosis between 1998 and 2004. 3 groups: stapedotomy without veinous interposition (92 cases), stapedotomy with veinous interposition (27 cases), stapedectomy (10 cases). Results given following AAO-HNS guidelines and GBP. Statistical analysis used: variance analysis test and t-Student test (p ? 0,05), graphic analysis of inter-aural difference before and after surgery. Results: Main benefit in air conduction (AC) threshold is 23 to 25 dB, no statistical difference between both techniques of stapedotomy. Stapedotomy gives better results than stapedectomy in this serie. Stereophony is achieved in 75% of overall cases with stapedotomy but normal hearing is achieved in only 53% of unilateral pre operative hearing loss. Comments: Stapedotomy is a more effective technique in this serie. Crossing informations achieved using AAO-HNS guidelines and GBP leads to give a more realistic and comprehensive understanding to patients who will undergo surgery for otosclerosis.
