颞下窝及翼腭窝巨大肿瘤通常经Fisch“C”形切除,优点为进路广,切除肿瘤安全,便于控制颈内动脉及面部无疤;缺点为患耳不可逆聋及有损伤面神经之虞。而Fisch“D”形颞下窝进路虽能保留听力,但暴露肿瘤受限。采用Fisch“D”形联合上颌或下颌-眶周进路切除颞下窝、翼腭窝、咽旁间 Large tumors in the infratemporal fossa and pterygopalatine fossa are usually resected by the Fisch “C”. The advantages are wide access, safe removal of the tumor, easy control of internal carotid artery and facial freedom, and the disadvantage of irreversible paralysis and damage to the facial nerve. While the Fisch “D” shaped infrapatellar approach preserves hearing, it is limited by exposure. Using Fisch “D” combined maxillary or mandibular - periorbital approach for resection of the infratemporal fossa, pterygopalatine fossa, and parapharyngeal approach
