目的:探讨颞骨高分辨率CT(HRCT)和咽鼓管功能检查对胆脂瘤型中耳炎患者术前咽鼓管鼓室口病变的诊断价值。方法:回顾性分析38例(41耳)胆脂瘤型中耳炎患者术前颞骨HRCT扫描和咽鼓管功能综合测试仪检查结果,并与术中显微镜下探查咽鼓管鼓室口处病变情况进行对比分析。结果:颞骨HRCT发现咽鼓管鼓室口软组织占位影34耳;术中发现鼓室口病变32耳,其中为肉芽组织22耳和胆脂瘤4耳,脓团堵塞3耳,鼓室口周围黏膜肥厚肿胀2耳,黏膜粘连闭锁1耳。咽鼓管功能障碍37耳,其中为阻塞型32耳,闭锁不全型5耳。结论:对胆脂瘤型中耳炎患者术前进行颞骨HRCT扫描和咽鼓管功能检查,对术中有目的地处理咽鼓管鼓室口的病变,制定手术方案和预估治疗效果具有重要意义。
Objective: To investigate the diagnostic value of temporal bone high resolution CT (HRCT) and eustachian tube function in preoperative eustachian tube tympanostomy in patients with cholesteatoma otitis media. Methods: 38 cases (41 ears) of cholesteatoma otitis media in patients with temporal bone HRCT scan and Eustachian tube function tester test results, and intraoperative exploration under the eustachian tube tympanic cavity lesions were compared analysis. Results: Temporal bone HRCT found 34 cases of soft tissues of eustachian tube tympanic cavity; 32 cases of tympanic cavity lesions were found in operation, including 22 ears of granulation tissue and 4 cases of cholesteatoma, 3 ears of pus group, mucosa hypertrophy around tympanic cavity 2 swelling, mucosal adhesions lock 1 ear. Eustachian tube dysfunction 37 ears, including obstructive 32 ears, incomplete obstruction 5 ears. Conclusion: The temporal bone HRCT scan and eustachian tube function examination in patients with cholesteatoma otitis media before operation is of great significance for the purposeful treatment of the eustachian tube tympanic cavity lesions, the development of surgical procedures and the prediction of the therapeutic effect.
