A case of per-surgery discovery of a pneumolabyrinth referred to the oval window is reported. Such was associated with a post-stapedectomy perilymphatic fistula. Revealing clinical signs were invalidating vertigo, transmission-type hearing loss, and tinnitus. Surgical plugging of the fistula caused the dizziness spells to regress completely, as well as improving tinnitus and restoring hearing markedly. Literature data confirm the fact that pneumolabyrinths are always associated with perilymphatic fistulas. Moreover, pneumolabyrinths seem to play an important role in the genesis of cochlear signs accompanying perilymphatic fistulas.
报告了一例术前发现累及卵圆窗的气迷路病例。该病例与镫骨切除术后外淋巴瘘相关。明显的临床症状为严重眩晕、传导性听力损失和耳鸣。手术封堵瘘管使眩晕发作完全消退，耳鸣改善，听力明显恢复。文献资料证实气迷路总是与外淋巴瘘相关。此外，气迷路似乎在伴随外淋巴瘘的耳蜗症状的发生中起重要作用。
