摘要
自1987年4月至1994年11月，收集鼓膜外傷性破孔面積超過30%的患者49例。造成破孔的因素以家庭暴力居多，有18例（36.7%），且全為女性。打架居次，有9例（18.3%），其中男性佔有8例。另外是挖耳道，有8例（16.3%）。49例中的43例，經過早期處理，以攤平內翻或外翻的鼓膜瓣使破孔變小，再以Gelfoam固定。術後追蹤良好的有39例。3星期癒合率是76%（30/39），3個月的癒合率是92%（36/39）。氣導骨導差平均從術前的17 dB降為術後的6 dB。除股膜破孔外，並無明顯中耳和聽小骨的合併症，只有1例挖破鼓膜並傷到鐙骨足板，造成外淋巴液外漏，經以軟組織修護成功。

From April 1987 to November 1994, 49 cases of traumatic tympanic membrane perforation with area larger than 30% were collected. The commonest cause of injury was a slap to the ear, occurring in 18 cases (36.7%), all of which were women. Other cases included: a blow to the head during a fight, ear picking, explosion, and traffic accidents. Forty-three of the 49 cases were treated early by smoothing out the infolded or out-folded flap of the tympanic membrane to reduce the size of the perforation, and then fixing this flap of the tympanic membrane between Gelfoam in the middle ear and silastic sheeting externally. Postoperatively, 4 cases were lost to follow-up. Of the remaining 39 cases, the healing rate was 76% (30/39) at 3 weeks and 92% (36/39) at 3 months. The average air-bone gap improved from 17 dB preoperatively to 6 dB postoperatively. Associated injury of the ossicles was found in one case only. This resulted from a stick being accidentally pushed into the ear, damaging the stapes foot plate and causing perilymph leakage. The perilymph fistula was closed successfully with soft tissue.
