目的比较改良乳突腔充填及耳甲腔成形术对开放式乳突手术的疗效。方法选取胆脂瘤型中耳炎和慢性中耳乳突炎患者76例,随机分为改良组和对照组各38例,对照组采用传统开放式乳突手术进行治疗,改良组在对照组治疗基础上改良乳突腔充填及耳甲腔成形术,2组患者均随访2年。比较2组患者耳甲腔成形所用时间、术后干耳时间、术后半年听力水平、并发症发生情况等。结果改良组耳甲腔成形所用时间与术后干耳时间均明显短于对照组,术后6个月气导听阈与骨气导差均明显低于对照组,并发症发生率明显低于对照组,差异均有统计学意义(P<0.01和P<0.05)。结论在开放式乳突手术中应用改良乳突腔充填及耳甲腔成形术,临床效果满意,值得推广应用。
Objective To compare the curative effect of open mastoid surgery with modified mastoid cavity filling and congenital cavity remodeling. Methods Sixty-seven patients with cholesteatoma otitis media and chronic otitis media were randomly divided into three groups: the modified group and the control group, 38 cases in each group. The control group was treated with open mastoid surgery. The modified group was treated on the basis of the control group Modified masticular cavity filling and congenital cavity plasty, 2 patients were followed up for 2 years. Comparing the time of forming cavum in two groups of patients, postoperative dry ear time, half a year after hearing level, complications and so on. Results The time of forming the auricular cavity and the time of postoperative dry ear were significantly shorter in the modified group than in the control group. The air conduction hearing threshold and the difference of air conduction were significantly lower at 6 months after operation than those in the control group. The complication rate was significantly lower than that of the control group , The differences were statistically significant (P <0.01 and P <0.05). Conclusions The application of modified mastoid cavity filling and congenital cavuloplasty in open mastoid surgery has satisfactory clinical effect and is worth popularizing and applying.
