  • Title: Temporal bone histopathologic findings in Alagille's syndrome.
    Author: Okuno T, Takahashi H, Shibahara Y, Hashida Y, Sando I.
    Journal: Arch Otolaryngol Head Neck Surg; 1990 Feb; 116(2):217-20. PubMed ID: 2297420.
    Abstract:
    Six temporal bones obtained from four individuals with Alagille's syndrome, aged 4 months and 3, 6, and 7 years, were studied histopathologically. The external auditory canals and tympanic membranes were normal. Although the stapes, the interossicular joints, and the subarcuate fossae were slightly underdeveloped in the majority of cases, the other structures in the middle ear were almost normal. However, severe anomalies were observed in structures in the inner ear. In all cases, both the bony and membranous structures of the posterior semicircular canal were partially or totally absent, and, in three ears, those of the anterior semicircular canal were also partially absent; the lateral semicircular canal, however, was normal in all cases. The cochlea was observed to be shortened in only one case.
