中耳胆固醇肉芽肿8例报告

目的 :探讨中耳胆固醇肉芽肿 (CG)的病因、发病机制、诊断及治疗。方法 :回顾性分析 8例 (9耳 )CG患者的临床资料。 8例 (9耳 )均为轻～中度传导性聋 ,鼓膜呈“蓝鼓膜”征 ,鼓室压曲线图为B型 (除 1例鼓膜紧张部穿孔外 ) ,其中 7例 (8耳 )行鼓室探查术 ,开放上鼓室、鼓窦及乳突气房 ,彻底清除肉芽组织 ,有 5例行中耳置管术 ,2例行中耳乳突改良根治术 ;另 1例仅行鼓膜穿刺抽液。结果 :1例失访。 7例 (8耳 )术后随访 0 .5～ 6年 ,6例 (7耳 )无复发 ;1例 (1耳 )复发 ,再次行手术治疗 ,术后 1年无复发。结论 :对不明原因的血性耳溢液及蓝鼓膜 ,应结合CT提高术前诊断率。对CG应采取手术治疗 ,清除病变 ,建立鼓室及乳突的通气、引流。

Cholesterol granuloma media:8 cases report

Objective:To investigate the etiology, pathogenesis diagnosis and therapy of cholesterol granuloma media.Method:Eight cases (9 ears) of middle ear cholesterol granuloma were retrospectively reviewed.Nine ears all have a speciality of conductive deafness with a light to middle level,blue eardrum and tympanogram all showing B type(except one case of eardrum perforation in the tension part).Seven cases(8 ears) were cured by tympanic cavity exploration opening epitympanum ,tympanic antrum,mastoid cells and thoroughly eliminating granulation tissue. Grommet insertion and modified radical mastoidectomy were performed on 5 cases and 2 cases,respectively. The other one case was only carried out with eardrum puncture.Result:Seven cases(8 ears) after operation were followed up for six monthes to six years.Six cases(7 ears )were cured out without recuring;one case (1 ear) recured.One case was not followed up.Conclusion:Otoblennorrhea of blood without obvious reason and blue eardrum should be coupled with CT to enhance the diagnosis rate before operation.CG should be treated by operation to clean disease location, air and drainage tympanicus cavity and mastoid.
