Abstract
Among congenital ossicular anomalies without external ear atresia, malleus fixation is least common. We report a case of congenital malleus fixation by a bony bar connecting the malleus neck to the posterior tympanic wall, which was depicted on thin-section CT scans.
摘要
在无外耳道闭锁的先天性听小骨异常中，锤骨固定最为少见。我们报告一例先天性锤骨固定病例，其锤骨颈与鼓室后壁之间由一根骨棒相连，此情况在薄层CT扫描中得以显示。
