Aural abnormalities in Klippel-Feil syndrome.

I Ohtani, C N Dubois

    The American Journal of Otology
    |November 1, 1985
    PubMed
    Summary

    Klippel-Feil syndrome can cause severe ear anomalies, including microtia and atresia. These findings highlight the complex congenital defects associated with this condition.

    Area of Science:

    • Medical Genetics
    • Otolaryngology
    • Developmental Biology

    Background:

    • Klippel-Feil syndrome is a congenital disorder characterized by the fusion of cervical vertebrae.
    • It is often associated with other congenital anomalies affecting various organ systems.
    • Hearing loss is a frequent comorbidity, second only to neurological defects.

    Observation:

    • Histologic examination of temporal bones from an infant with Klippel-Feil syndrome was performed.
    • The study focused on the detailed anatomy of the inner and middle ear structures.
    • Specific attention was given to anomalies in the affected ear.

    Findings:

    • Severe anomalies were observed in one ear, including microtia (abnormally small ear) and aural atresia (absence of ear canal).
    • Maldeveloped ossicles, a fixed stapes, and a hypoplastic facial nerve were noted.
    • Further abnormalities included a shortened cochlea and an enlarged lateral semicircular canal.

    Implications:

    • These findings underscore the significant otologic manifestations of Klippel-Feil syndrome.
    • Early identification and management of hearing loss in affected individuals are crucial.
    • This case provides detailed insights into the complex craniofacial and otologic developmental disruptions in Klippel-Feil syndrome.
