###Human: How can otosclerosis be treated? ###Assistant: Hello. Otosclerosis often causes mixed hearing loss and can cause a maximum hearing loss of 60 to 70 db hearing loss which can be serviced to a good degree by doing stapedotomy. However, aging often causes presbyacusis that is an age-induced hearing loss which is neural and not salvageable by surgery. Since stapedotomy is a procedure done under local anesthesia, it may be still considered. However, it is possible if there is no significant SNHL (sensorineural hearing loss).
