Abstract

Primary adenomatous tumors of the middle ear are preponderantly benign, resectable lesions and arise from the mucosa (adenomas) or salivary tissue (choristomas). Malignant variants are ill defined, are not characterized histologically, and represent less than 10% of the adenomatous tumors. Their presence may be signaled clinically by facial nerve paralysis, invasion of bone, and chronic otorrhea.

摘要

中耳原发性腺瘤性肿瘤主要是良性的、可切除的病变，起源于黏膜（腺瘤）或涎腺组织（迷芽瘤）。恶性变体定义不明确，缺乏组织学特征，在腺瘤性肿瘤中占比不到10%。它们的存在可能在临床上表现为面神经麻痹、骨质侵犯和慢性耳漏。
