目的 :探讨彻底切除前中颅底、咽、咽旁间隙肿瘤的理想手术入路。方法 :采用不同部位的上颌外旋入路切除 16例前、中颅底肿瘤 ,此 16例肿瘤均累及多区 ,范围广泛 ;采用下颌外旋入路治疗 2 6例鼻咽、口咽、咽旁及颅底肿瘤。结果 :16例上颌外旋术后随访 2～ 5年 ,生存 4年以上 3例 ,3年以上 6例 ,2年以上 6例 ,术后 1.5月死亡 1例。 2 6例下颌外旋术后随访 18个月～ 6年 ,4例良性肿瘤情况良好 ,无复发 ,2 2例恶性肿瘤中 ,2例 0 .5年内死亡 ,2例 1年余复发 ,1例术后 2年死于肺部转移 ,4例存活 5年以上 ,6例存活 4年以上 ,3例存活 3年以上 ,3例存活 2年以上 ,1例存活 1年以上。大部分病例仍在继续随访中。结论 :上颌外旋及下颌外旋入路是彻底切除前中颅底、咽、咽旁间隙肿瘤理想、可靠的手术入路 Objective: To investigate the ideal surgical approach for radical resection of the anterior skull base, pharynx and parapharyngeal space. Methods: Sixteen cases of anterior and middle skull base tumors were excised by different parts of the maxillary maxillary approach. The 16 tumors all involved multiple regions and had a wide range. Twenty-six cases of nasopharyngeal, oropharyngeal and pharyngeal pharyngeal Next to the skull base tumor. Results: 16 cases were followed up for 2 to 5 years after operation of maxillary maxillofacial surgery, 3 cases survived for more than 4 years, 6 cases were over 3 years, 6 cases were over 2 years and 1 case died after 1.5 months. Twenty-six cases of mandibular external rotation were followed up for 18 months to 6 years. Four of the benign tumors were in good condition with no recurrence. Of the 22 malignant tumors, 2 died within 0.5 year, 2 cases relapsed more than 1 year, and 1 case Four died of lung metastases 2 years after surgery, 4 cases survived more than 5 years, 6 survived more than 4 years, 3 survived more than 3 years, 3 survived more than 2 years and 1 survived for more than 1 year. Most cases are still under follow-up. Conclusion: Maxillary external rotation and mandibular circumflex artery are the ideal and reliable surgical approach for radical resection of anterior skull base, pharyngeal and parapharyngeal space tumors
