[Surgery of otosclerosis. Retrospective study and review of the literature].

Between 1990 and 1996 we have operated 134 patients with otosclerosis. 91 were female and 43 male with 42 years average. We report a retrospective study and collect a string of clinical preoperative variables analysing the kind of surgery performed with the findings and most relevant technical difficulties, complications and hearing improvement obtained just after the operation and one month later. Stapedectomy or stapedotomy have given good results in our serie with significant hearing recuperation on more than 90% of the cases well selected and operated by first time.
