咽旁间隙肿瘤(附89例临床分析)

Parapharyngeal space tumors:with a clinical analysis of 89 cases

目的：总结诊治咽旁间隙肿瘤的经验。方法：回顾分析咽旁间隙肿瘤８９例。术前为３２例患者行针吸活检术，５０例行ＣＴ检查；全部患者均行手术治疗，经腮腺入路２９例，经颈入路４５例，经颈—下颌骨外旋入路１５例，术后全部标本作病理检查。结果：针吸活检３２例中２７例诊断正确，ＣＴ检查５０例中４６例可准确判断肿瘤的位置；组织学检查良性肿瘤７２例（８１％），以恶性肿瘤、混合瘤多见３７（４２％）。良性肿瘤术后１０例复发（１４％），恶性肿瘤１２例复发或转移（７４％）。结论：术前针吸活检和ＣＴ检查对诊断咽旁肿瘤有意义，经腮腺和经颈部入路是最常用手术进路。

Objective:To evaluate the experience of the diagnosis and management of tumors of parapharyngeal space(PPS).Methods:The clinical data of 89 patients(39 male and 50 female) were retrospectively analyzed.Before surgical operation,32 patients undertook fine needle aspiration,50 patients had CT imaging.All were treated surgically by the approach of parotid in 29 cases,by neck in 45 cases,by neck-mandibular in 15 cases.Results:Fine needle aspiration was accurate in the diagnosis in 27 of the 32 patients,CT imaging were able to identify the position of the tumors in 46 of the 50.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 tumors.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.
