摘要
目的:对改良Borbosa手术进路在原发或继发性翼腭窝肿瘤处理的疗效评价。方法：在Borbosa手术切口的基础上，把口内上颌结节的切口经翼下颌韧带外侧向下达磨牙后区，然后向前达尖牙处以更好地暴露翼腭窝。对利用该手术进路治疗原发性或继发性翼腭窝肿瘤患者9例进行了影像学检查分析。结果：9例患者中4例肿瘤原发于翼腭窝，其中2例继发性地侵犯上颌窦；2例肿瘤原发于上颌骨；2例原发于腮腺深叶；1例为颅外脑膜瘤。9例均进行了术后3个月～9年6个月的追踪，其中1例术后2年2个月复发。结论：改良的Borbosa手术进路对翼腭窝肿瘤或翼腭窝肿瘤扩展进入上颌窦是特别有用的。
Objective: To evaluate effects of modified Borbosa surgical approach that has been applied to managing primary tumors in the pterygopalatine fossa and secondary tumors involving the pterygopalatine fossa. Methods: The Barbosa approach was modified by adding a lateral incision in the mandibular gingivobuccal fold from the canine tooth to the retromolar area. This technique was applied to nine patients with primary and secondary tumors in the pterygopalatine fossa, All patients had been observed by clinical examinatmn. MRI and CT examinations. Results: This technique allowed a large, inferiorly based flap to be raised, which includes the parotid gland. The masseter and temporalis muscles was divided horizontally, and the ascending ramus of the mandible was osteotomied between the mandibular angle and the sigmoid notch and reflected to expose the tumor in the pterygopalatine fossa and maxillary sinus. Nine patients have applied this technique. Four of the nine patients had primary tumors in the pteygopalatine fossa, two patients had tumors in the pterygoaplatine fossa extending into the maxillary sinus; Two patients had tumors occurring in the maxilla involving the pterygopalatine fossa;Two patients had tumors from deep lobe of the parotid gland to the pterygopalatine fossa; One patient had extracranial meningioma. Nine patients have been followed up from 3 months to 9 years and 6 months, one of them had recurrence 2 years and 2 months postoperatively. Conclusion: This technique is especially useful to tumors in the pterygopalatine fossa and tumors in the pterygopalatine fossa extending into the maxillary sinus.
