Open cavity mastoidectomy techniques cause some cavity problems. We used inferior pedicled composite multifractured osteoperiosteal flap, which is our original surgical approach to obliterate the mastoid cavity, reconstruct the external auditory canal (EAC), and to prevent open cavity problems.
Composite multifractured osteoperiosteal flap was used to obliterate the mastoid cavity and reconstruct the EAC in four patients (2 females, 2 males; mean age 34; range 31 to 38 years) who previously underwent radical mastoidectomy to treat chronic otitis media with cholesteatoma. Small meatoplasty was applied in all the patients to relive their esthetical concerns. The patients were followed-up for two years.
The epithelization of the new EAC was complete at the end of the second month. Cholesteatoma, granulation, or recurrence of osteitis did not occur in any of the patients. We detected new bone formation filling the mastoid cavity on postoperative temporal bone CT images.
An almost natural EAC was obtained due to neo-osteogenesis that developed behind the composite multifractured osteoperiosteal flap.
开放式乳突根治术会引发一些术腔问题。我们采用带蒂下复合多骨折骨膜瓣，这是我们用于消除乳突术腔、重建外耳道（EAC）并预防术腔相关问题的原创手术方法。
对4例（2例女性，2例男性；平均年龄34岁；年龄范围31至38岁）既往接受过根治性乳突切除术以治疗胆脂瘤型慢性中耳炎的患者，采用复合多骨折骨膜瓣消除乳突术腔并重建外耳道。所有患者均进行了小耳廓成形术以缓解其美观方面的顾虑。对患者进行了为期两年的随访。
第二个月末，新外耳道上皮化完成。所有患者均未出现胆脂瘤、肉芽或骨炎复发。术后颞骨CT图像显示乳突术腔内有新骨形成。
由于复合多骨折骨膜瓣后方出现了新骨形成，获得了几乎自然的外耳道。
