目的 :探讨分期鼓室成形手术治疗慢性化脓性中耳炎的疗效。方法 :对 36例 (36耳 )本病患者 1期手术行乳突根治术 ,其中 2 6耳为开放式术式 ,10耳为关闭式术式。次期手术主要连接听骨链 ,其中 型 2耳 , 型 2 5耳 , 型 5耳 ;另 4耳无法成形者则行单纯乳突根治术。结果 :36例中 32例成功 ,4例失败。结论 :分期鼓室成形手术可挽救大部分慢性化脓性中耳炎患者的术后听力 ,在中耳粘膜增厚、粘膜缺损较小或术前咽鼓管不通的病例可获得较好的效果 ;但对中耳粘膜缺损较大的病例效果较差 ;手术成功的关键在于术后中耳形成含气空腔
Objective: To investigate the effect of phased tympanoplasty in the treatment of chronic suppurative otitis media. Methods: Thirty-six patients (36 ears) underwent radical mastectomy with surgery of the first stage, of which 26 were open and 10 were closed. Secondary surgery is connected to the ossicular chain, which type 2 ears, type 2 5 ears, type 5 ears; the other 4 ears can not be formed were simple mastoidectomy. Results: 32 of 36 cases were successful and 4 cases failed. Conclusions: Phased tympanoplasty can save the majority of patients with chronic suppurative otitis media postoperative hearing, in the middle ear mucosa thickening, mucosal defects smaller or preoperative eustachian tube unreasonable cases can get better results; but in the Ear mucosa defects larger cases less effective; the key to the success of surgery is the formation of air-containing cavity after the middle ear
