However, pregnancy seems to hasten presentation. The incidence of otosclerosis also increases with age. [asams.org]

The CT and clinical findings are considered typical, and a family history need not be present to suggest the diagnosis of X-linked congenital hearing loss. In four patients reported by Talbot and Wilson ( 4 ), a family history was not present. [ajnr.org]

Differential diagnosis Differential diagnosis should include minor ossicular malformations presenting with a normal otoscopy, a conductive hearing loss, and abolished stapedial reflexes. [orpha.net]

• Hearing Impairment

  X-linked Disorders Alport syndrome X-linked mixed hearing impairment with stapes fixation and perilymphatic gusher. Hereditary causes of hearing loss are suspected in all cases of hearing impairment. [pediatric-ent.com]

  CAUSES OF HEARING IMPAIRMENT If there is some difficulty in the external (outer) or middle ear, a conductive hearing impairment occurs. [potomacaudiology.com]

  Affiliated tissues include bone, and related phenotypes are bilateral conductive hearing impairment and stapes ankylosis [malacards.org]

  Affected females manifest bilateral, moderate hearing impairment that affects the high frequencies ( Fig. 2 C). [academic.oup.com]

  Synonym: otospongiosis Otosclerosis (OTSC) is the single most common cause of hearing impairment. [patient.info]

Prognosis OTSC treated surgically has a good prognosis in the vast majority of cases. The rate of hearing deterioration with time after stapedotomy does not exceed that due to presbyacusis [ 21 ] . [patient.info]

Prognosis In 90 of 100 patients, the operation is completely successful, in that the hearing is markedly improved. In 8 out of 100 patients, the hearing is improved, but not quite as much as hoped for. [bcm.edu]

Prognosis People with otosclerosis almost never become totally deaf, and will usually be able to hear with a hearing aid or with surgery plus a hearing aid. [medical-dictionary.thefreedictionary.com]
