Type V tympanoplasty with fenestration of the oval window and protection of the round window in a residual hypotympanic cavity can be considered as the last-chance procedure for rehabilitation of hearing in ears with 'canal wall down' or other conditions. The review of 64 cases suggests that restoration of hearing can be adequate in the majority of cases.
对于存在残留鼓室下腔的“开放式”或其他情况的耳朵，采用卵圆窗开窗及圆窗保护的Ⅴ型鼓室成形术可被视为听力康复的最后机会手术。对64例病例的回顾表明，大多数情况下听力恢复可以令人满意。
