目的总结中耳颈静脉球体瘤的临床表现、诊断和治疗体会。方法回顾分析中耳颈静脉球体瘤典型病例2例,主要症状为听力下降,反复少量出血,无眩晕、耳鸣。检查见鼓室内有暗红色新生物突向外耳道,无明显搏动,乳突CT:乳突呈硬化型,鼓室有软组织影,突向外耳道,增强扫描有均匀强化。电测听听力呈中重度感音神经性聋。行开放式乳突根治术,术后碘仿纱条填塞、换药。结果外耳道出血症状消失,但听力无明显提高,中耳乳突术腔干燥,上皮化良好,术后病理报告化学感受器瘤。结论中耳颈静脉球体瘤临床极少见,易误诊,因病灶局限于鼓室内,可行开放式乳突根治术,不易复发。
Objective To summarize the clinical manifestation, diagnosis and treatment of middle ear jugular bulb tumor. Methods Retrospective analysis of 2 cases of typical cases of middle ear jugular bulb tumor, the main symptoms of hearing loss, repeated a small amount of bleeding, no vertigo, tinnitus. Check to see the tympanic cavity dark red new biological sudden outward ear canal, no significant beating, mastoid CT: mastoid sclerosis, tympanic soft tissue shadow, protruding to the external auditory canal, enhanced scanning with uniform enhancement. Electrical audiometry was moderate to severe hearing loss of nerve deafness. Open mastoidectomy, postoperative iodoform gauze packing, dressing change. Results The symptoms of external auditory canal disappeared, but no significant improvement of hearing. The middle ear mastoid cavity was dry and the epithelialization was good. Postoperative pathological report of chemosensory neoplasm. Conclusions The middle ear jugular bulb tumor is extremely rare and easily misdiagnosed. Because the lesion is confined to the tympanic cavity, it is feasible to treat with open mastoid radical and not recur.
