Three patients are reported in whom sound-conduction deafness was caused by malignant tumors in the tubal-tympanic area of the middle ear. In all patients, physical examination (inclusive of the ear and nasopharynx) had essentially been normal for a long time. In each patient, the tympanogram obtained indicated a tympanic effusion which, however, proved to be therapy-resistant. The first patient was found to have a malignant melanoma of the auditory tube while the second patient had an adenoid cystic carcinoma of the middle ear. The last patient had a primary carcinoma which at first showed only peritubal and submucosal growth.
报告了3例患者，其传导性耳聋由中耳鼓室管区域的恶性肿瘤引起。所有患者的体格检查（包括耳部和鼻咽部）长期基本正常。每位患者的鼓室图均显示有鼓室积液，但事实证明对治疗有抵抗性。第一名患者被发现患有咽鼓管恶性黑色素瘤，而第二名患者患有中耳腺样囊性癌。最后一名患者患有原发性癌，起初仅表现为咽鼓管周围和黏膜下生长。
