Familial ossicular malformations: case report and review of literature.
Familial middle ear ossicular anomalies are rare. We report on a daughter and her mother with congenital conductive hearing loss. Tympanotomy disclosed hypoplasia of long crus of incus whose tip had been replaced with a fibrous strand. A review suggests that middle ear ossicular anomalies may be inherited as autosomal dominant traits. Most individuals were bilaterally affected. Most isolated cases were affected unilaterally.
