咽旁间隙肿瘤89例

目的 为咽旁间隙肿瘤的诊断和选择提供资料依据。方法对我院收治的89例咽旁间隙肿瘤作了回顾分析。术前32例病人作了针吸活检，50例作了CT检查；全部病人均行手术治疗，主要采用经腮腺和经颈部入路手术，术后全部标本作病理检查。结果在32例针吸活检病人中27例诊断正确，50例CT检查中46例可准确判断肿瘤的位置；组织学检查见良性肿瘤72例(81％)，恶性肿瘤17(19％)，以混合瘤最为多见，共37例(42％)。结论显示针吸活检和CT对咽旁肿瘤的术前诊断和评估十分重要，经腮腺和经颈部入路是最常用手术进路，咽旁肿瘤术的复发率高。

A Clinical Analysis on 89 Parapharyngeal Space Tumors

Objective To provide basis to the diagnosis and operation mode of parapharyngeal tumors.Methods 89 patients (39 males and 50 females) were found to have PPS tumors. Before surgical operation 32 patients had fine needle aspiration, 50 patients had CT imaging. All patients were treated surgically, the transparotid and transcervical approach were most widely used.Results Fine needle aspiration was accurate in the diagnosis in 27 of the 32 patients, 46 of the 50 CT imaging were able to identify the position of the tumors. Histopathologic analysis found that 72 cases (81%) were benign and 17(19%) were malignant. Pleomorphic aclenoma was the most common tumor. Recurrence was recorded in 10 of benign tumors, 12 in malignant. Conclusion Fine needle aspiration and CT imaging are essential and critical for the preoperative assess and diagnosis.Transparotid and transcervical approach are most widely used. Recurrence rate is high for PPS tumors.
