咽旁间隙肿瘤较少见,在头颈部肿瘤中所占比例不足0.5％。虽然大多数咽旁间隙肿瘤为良性,但肿瘤类型的多样化和解剖的复杂性,使其诊断和治疗变得困难。作者回顾分析过去30年内诊治咽旁间隙肿瘤的经验,对肿瘤的组织学类型、临床特征和手术治疗效果进行了重点论述。 1960～1990年间,Mayo诊所共收治172例初发型咽旁间隙肿瘤患者,其中男性96例,女性76例,年龄11.7月～91.5岁。所有患者均经手术治疗,术前进行高分辨CT或MRI检查,明确诊断和制订手术方案。9
Parapharyngeal space tumors are rare, accounting for less than 0.5% of head and neck cancers. Although most parapharyngeal space tumors are benign, the variety of tumor types and the complexity of anatomy make it difficult to diagnose and treat them. The author reviewed the experience of diagnosis and treatment of parapharyngeal space tumors in the past 30 years and focused on the histological types, clinical features, and surgical treatment effects of the tumor. Between 1960 and 1990, Mayo Clinic admitted a total of 172 patients with early-onset parapharyngeal space tumors, including 96 males and 76 females, aged from 11.7 months to 91.5 years. All patients were treated by surgery. High-resolution CT or MRI examinations were performed before surgery to confirm the diagnosis and make a surgical plan. 9
