目的 探讨咽旁间隙肿瘤的手术径路。方法 对１９８８ ～１９９８ 年间收治的３８ 例咽旁间隙肿瘤资料作回顾分析。结果 咽旁间隙肿瘤中良性肿瘤２７ 例，占７１ ％ ，其中１８ 例为神经源性肿瘤。恶性肿瘤１１ 例，占２９ ％ 。５ 例经口咽径路切除肿瘤；２２ 例经颈颌径路切除肿瘤；８ 例经颈—腮腺径路切除肿瘤；２ 例侵及颅底的咽旁间隙肿瘤采用侧颅底径路切除。结论 经口咽径路仅适于较小的肿瘤切除；经颈—腮腺径路主要用于入咽旁间隙的腮腺深叶肿瘤的切除；经颈颌径路为切除咽旁间隙肿瘤首选的安全有效的径路。
Objective To explore the surgical approach of parapharyngeal space tumor. Methods The data of 38 cases of parapharyngeal space tumors admitted from 1988 to 1998 were retrospectively analyzed. Results There were 27 benign tumors in parapharyngeal space, accounting for 71%, of which 18 were neurogenic tumors. Malignant tumors in 11 cases, 29%. Five patients underwent resection of the tumor via the oropharyngeal approach, 22 underwent resection of the tumor via the cervical approach, 8 underwent resection of the tumor through the neck-parotid approach, and 2 had parapharyngeal space-related tumors that had penetrated the base of the skull. Conclusions The oro-pharyngeal approach is only suitable for smaller tumor resection. The trans-pharyngeal approach is mainly used for excision of the parotid deep-lobe tumor into the parapharyngeal space. The neck and parotid gland approach is the preferred safe and effective approach for the removal of parapharyngeal space tumor .
