目的 :探讨经扩大迷路进路摘除伴发慢性中耳乳突炎的大听神经瘤的手术方法。方法 :先一期手术彻底清除鼓室乳突病灶 ,术毕封闭中耳乳突腔 ;2周后行二期手术 ,经一期径路进行听神经瘤切除术。结果 :2例并发慢性中耳炎的大听神经瘤均得到全切 ,术后面神经功能正常 ,切口一期愈合。随访半年以上无感染发生。结论 :并发慢性中耳乳突炎的大听神经瘤同样可经扩大迷路进路进行手术切除 Objective: To explore the surgical method of enlarging acoustic pathology of large acoustic myeloma associated with chronic otitis media. Methods: The first stage of surgery to completely clear the tympanic mastoid lesions, surgery completed closure of the middle ear milk cavity; 2 weeks after the second phase of surgery, the first phase of acoustic neuroma resection. Results: 2 cases of large otolaryngitis complicated with chronic otitis media were completely resected. The facial nerve functioned normally and the incision healed one time. Follow-up more than six months without infection. Conclusions: Large acoustic neuroma with chronic otitis media can also be surgically removed by enlarging the lost path
