前中颅底沟通瘤的手术入路和显微切除

目的：探讨前中颅底沟通瘤的手术入路和颅底重建的方法。方法：采用经额鼻筛眶入路、经额颞眶颧入和经额颞联合耳前颞下入路暴露肿瘤，予于显微手术切除。结果：１７例该部位肿瘤施一微手术治疗，肿瘤全切除１１例，次全切除３例，大部分切除３例。手术结果良好，无手术死亡及严重并发症。结论：前中颅底内外沟通瘤应根据肿瘤位置、侵犯范围选择适当手术入路，充分暴露病灶，有利于广泛切除肿瘤。颅底重建是避免脑脊液漏及颅内感染的

APPROACH AND MICROSURGERY TO REMOVE THE COMMUNICATIVE TUMORS INVADING BOTH ANTERIOR AND MIDDLE SKULL BASE

Objective:To investigate surgical approaches and the methods of skull base reconstruction for the communicating tumors invading both anterior and middle skull base Methods:The fronto naso ethmoido orbital approach,fronto tomporo orbito zygomatic approach and combined fronto tomporo preauricular subtempporal approach were applied to expose tumors which wereresected by microsurgery Result:17cases with the communicative tumors invading both anterior and middle skull base underwent microsurgery The tumors were totally removed in 11 cases,subtotally in 3 and mostly in 3 cases The operative results were excellent and there was,no operative mortality and serious complication Conclusion:Different approach should be selected,depending on location and invading extension of tumor,which can provide excellent exposure and allow for an aggressive resection of the tumor skull base reconstruction is the key to avoid craniocerebral fluid leakage and infection
