目的 :探讨咽旁间隙良性肿瘤的主要临床特征、诊断方法及临床治疗效果。方法 :回顾分析我院于2010年1月~2014年1月期间经手术治疗的100例咽旁间隙良性肿瘤患者的临床资料,对患者进行CT检查、磁共振成像(magnetic resonance imaging,MRI)检查,分析探讨其病理类型、手术路径及有无并发症发生。结果 :100例患者中绝大部分体征表现为咽侧壁膨隆、软腭隆起和扁桃体移位及颈部肿物,但部分患者未发现阳性体征,仅影像学检查显示咽旁间隙占位。患者术后组织病理学类型多样,主要为多形性腺瘤和神经鞘瘤。手术路径分为单纯颈侧切口入路、经口径路、经颈侧-腮腺入路及经颈侧-下颌骨裂开。术后随访3个月~24个月,平均随访18个月,复发2例。结论 :咽旁间隙位置通常十分隐蔽且解剖毗邻复杂,发生于该间隙的肿瘤多无特异性症状,病理类型种类繁多。CT检查和磁共振成像是临床诊断咽旁间隙肿瘤的重要工具。目前咽旁间隙良性肿瘤以单纯颈侧切口径路切除为主,一次性完整切除率高,且患者复发率较低,值得推广应用。
Objective: To explore the main clinical features, diagnosis and clinical treatment of parapharyngeal space benign tumor. Methods: The clinical data of 100 patients with benign parapharyngeal space surgically treated in our hospital from January 2010 to January 2014 were retrospectively analyzed. The CT examination, magnetic resonance imaging (MRI) examination , Analyze the pathological type, surgical path and the occurrence of complications. Results: The majority of the 100 patients showed bulging pharyngeal wall, soft palate uplift and tonsil displacement and neck mass. However, some patients did not find positive signs. Only the imaging of the parapharyngeal space was found. Postoperative histopathological types of patients, mainly pleomorphic adenoma and schwannoma. Surgical approach is divided into simple neck incision approach, by the caliber, the neck side - the parotid approach and the neck side - mandibular split. The patients were followed up for 3 months to 24 months, with an average follow-up of 18 months and 2 relapses. Conclusion: The location of parapharyngeal space is usually very subtle and the adjacent anatomy is complicated. There are many non-specific symptoms of tumor in this space, and a great variety of pathological types. CT examination and magnetic resonance imaging is an important tool for clinical diagnosis of parapharyngeal space tumor. At present, parapharyngeal space benign tumors are mainly excised by simple neck incision, and the rate of one-time complete resection is high and the recurrence rate of patients is low, so it is worth popularizing and applying.
