Abstract:
OBJECTIVE:To describe the HRCT appearances of congenital inner ear malformations with cerebrospinal fluid leakage.
METHOD:Conducted a retrospective case review. The subjects comprised 11 patients who were decisively confirmed by HRCT and exploratory tympanotomy. The result of temporal bone computed tomography scans (HRCT) were analyzed.
RESULT:Inner ear malformations were classified into 4 types according to HRCT findings. There were 4 patients with cochlear aplasia, 2 patients with common cavity anomaly, 2 patients with IP-I anomaly, and 3 patients with IP- II anomaly. Eight patients had defects in the lamina cribrosa of the internal auditory canal. The development and aeration in the mastoid of involved ears was normal. Soft tissues were seen near the oval window in all involved ears.
CONCLUSION:HRCT image has an important value in the diagnosis and treatment of inner ear malformations with cerebrospinal fluid leakage.
