I．はじめに

　外傷性髄液耳漏は側頭骨錐体部の骨折直後に出現することが多く，その大多数は自然治癒する^11）．われわれは受傷6年後に発症した遅発性髄液耳漏の症例を経験し，修復術を行った．遅発性髄液耳漏の機序と手術適応について若干の文献的考察を加えて報告する．

A 16 year-old female was admitted to our hospital because of left temporal hone fracture and brain contu-sion in the left temporal lobe. CSF otorrhea was also present for a week. Four years later, when she was 20 years old, she was noticed to have a white mass in the left external auditory canal. One and a half year later, left CSF otorrhea reappeared, and she was readmitted to our hospital.

High resolution coronal CT revealed that the left temporal bone fracture had opened widely and brain tissue had herniated into the left external auditory can-al. Metrizamide CT cisternography showed that CSF was leaking around the mass.
