    摘要:

    目的 探讨中耳神经源性肿瘤的临床特征、诊治方法及预后。方法 回顾性分析2010-2022年间我院经病理确诊为中耳神经源性肿瘤的7例患者的临床资料。结果 7例患者中以听力下降为主诉的有3例,耳流脓3例,周围性面瘫1例(H-B分级为VI级)。肿瘤侵犯外耳道并以外耳道肿物为表现4例,鼓膜紧张部穿孔3例。中耳CT肿瘤累及面神经水平段2例,侵犯面神经颞骨内段全程并侵入中颅窝1例,其余病变位于中鼓室及鼓岬表面4例。7例患者均在彻底清除病变的基础上一期行鼓室成形术。术后病理确诊为:鼓室体瘤3例、面神经纤维瘤2例、面神经鞘膜瘤1例、中耳神经内分泌腺瘤1例;其中面神经鞘膜瘤和中耳神经内分泌腺瘤术前活检分别诊断为中耳胆脂瘤和慢性化脓性中耳炎,术前病理误诊率为28.6%。术后随访1年-8年,目前尚无复发病例。结论 中耳神经源性肿瘤发病率较低且临床表现各异,存在一定的误诊率,术前完善CT和增强MRI检查以及术后病理及免疫组化有助于明确诊断。手术是治疗该病的有效手段。

    Abstract:

    Objective To investigate the clinical features, diagnosis and treatment methods and prognosis of neurogenic tumors in the middle ear..Method The clinical data of 7 patients who were pathologically diagnosed with neurogenic tumors of the middle ear in our hospital during 2010-2022 were retrospectively analyzed.Result Among the 7 patients, 3 complained of hearing loss, 3 of them had purulent ear flow, and 1 of them had peripheral facial paralysis (H-B grade VI). The tumor invaded the external auditory canal and manifested as external auditory canal mass in 4 cases and tympanic tensor perforation in 3 cases. CT tumors in the middle ear involved the horizontal segment of the facial nerve in 2 cases, invaded the internal segment of the facial nerve and invaded the middle cranial fossa in 1 case, and the other lesions were located on the surface of the middle tympanum and promontory in 4 cases. All the 7 patients underwent tympanoplasty on the basis of complete removal of the lesions. The postoperative pathological diagnosis was as follows: 3 cases of tympanosoma, 2 cases of facial neurofibroma, 1 case of facial schwannoma, 1 case of middle ear neuroendocrine adenoma; Cholesteatoma of the middle ear and chronic suppurative otitis media were diagnosed by preoperative biopsies of facial neurememoma and neuroendocrine adenoma of the middle ear, respectively. The preoperative pathological misdiagnosis rate was 28.6%. The patients were followed up for 1-8 years after surgery, and no cases of recurrence were reported..Conclusion The incidence of neurogenic tumors in the middle ear is relatively low with different clinical manifestations, and there is a certain misdiagnosis rate. Preoperative CT and enhanced MRI examination, as well as postoperative pathology and immunohistochemistry are helpful for definite diagnosis. Operation is an effective means to treat the disease.
