Otosclerosis is a familial hereditary genetic disease which manifests with progressive conductive hearing loss and tinnitus. In the majority of cases the disease affects both ears. In 5% of cases otosclerosis is an unilateral disease.
The disease is characterized by conductive hearing loss and tinnitus. The diagnosis is basically instrumental and achieved by tonal and vocal audiogram and study of the stapedial reflex.
The otosclerosis has 4 stages going from stage 1 disease with moderate deafness and normal cochlear function up to stage 4 with profound deafness and severe cochlear function compromised. Surgery is the treatment of choice because, despite it is not curing the disease, is the only one able to allow an almost complete recovery of hearing loss.
Stapedotomy is performed under local anesthesia, with microdrill or diode laser depending on the cases.
The patient is treated in a Day Surgery regimen. The first postoperative control is after 8 days. The first audiometric test to verify the hearing recovery is performed one month after surgery.
In the personal series of more than 1500 cases the success rate is about 90%. Revision surgery was performed in approximately 5 cases / year.
