摘要
目的探讨中耳先天性胆脂瘤的诊断及预后。方法回顾性分析9例中耳先天性胆脂瘤。结果平均年龄为6.1岁,均有听力下降,耳镜检查见6例鼓膜后象限白色团块。8例患者术前CT发现鼓室内圆形或卵圆形软组织影。所有病例均行手术,复发率为44.4%(4/9)。随访平均7.4年,术前平均听阈28dB,术后平均听阈26dB。结论中耳先天性胆脂瘤临床少见。单侧传导性耳聋为主要表现。术前诊断可根据Levenson诊断标准和CT检查结果。其预后和复发率与病变范围、手术方式、是否二次手术有关。
Objective To investigate the location,clinical symptoms,image features,treatment and prognosis of congenital middle ear cholesteatoma. Methods A retrospective analysis was made in 9 patients with congenital middle ear cholesteatoma. Results The mean age of the patients was 6.1 years ,and all the patients suffered from conductive hearing loss. The otoscopic examination showed typieal cholesteatoma behind posterior tympanic membrane in 6 cases.Preoperative CT in 8 of 9 eases showed spheroid or ovoid masses in the tympanic cavities. All the patients underwent surgery,and the recurrence rate was 44.4%（4/9）. All of the cases were followed up for a mean period of 5.3 years,the preoperative hearing threshold was 28dB and postoperative heating threshold was 26dB. Conclusion Congenital middle ear cholesteatoma is a rare and hiding lesion. The typical symptom is unilateral conductive hearing loss.Preoperative diagnosis may be based on Levenson diagnostic criteria and CT imaging. The prognosis and recurrence rate are correlated with the lesion scope,surgical approach,and second operation.
