目的观察联合进路鼓室成形术治疗慢性化脓性中耳炎手术疗效。方法应用联合进路鼓室成形术治疗慢性化脓性中耳炎４２例共４８耳，其中Ⅰ期手术者２４例２８耳，分期手术者１８例２０耳，术后随访３—５年。结果Ⅰ期及分期手术后鼓膜愈合率分别为７５％和９０％，胆脂瘤复发率为２１４３％及５％，语言频率（０５、１、２ｋＨｚ）纯音听阈均值气骨导差小于２０ｄＢＨＬ者分别为１３耳（４６４３％）和１５耳（７５％），其中儿童患者分期手术术后胆脂瘤无一例复发。结论联合进路鼓室成形术分期手术治疗慢行化脓性中耳炎远期效果显著，儿童患者行该术时以分期手术为宜。
Objective To observe the effect of combined approach tympanoplasty in the treatment of chronic suppurative otitis media. Methods Forty-eight cases of chronic suppurative otitis media were treated by tympanoplasty combined with approach, including 24 cases of stage Ⅰ surgery, 28 cases of ears and 18 cases of stage surgery, 20 cases were followed up for 3 to 5 years. Results The healing rates of stage Ⅰ and stage eardrum were 75% and 90% respectively, the recurrence rates of cholesteatoma were 2143% and 5%, and the frequency of pure tone threshold (05,1,2 kHz) Thirteen ears (46.43%) and 15 ears (75%) were less than 20dBHL, respectively. There was no recurrence of cholesteatoma in pediatric patients after operation. Conclusions The combined approach of tympanoplasty staged surgery for chronic suppurative otitis media long-term effect is significant, pediatric patients underwent surgery to staging surgery is appropriate.
