The infratemporal fossa approach type A is the best way to deal with recurrent tympano-jugular paragangliomas because facial nerve rerouting is fundamental to reaching the area of the internal carotid artery, where recurrence is likely to occur. Preservation of lower cranial nerve function is not feasible when there is tumor infiltration of the medial wall of the jugular bulb; any attempt at nerve dissection increases the risk of leaving some tumor remnants. Correct management of the internal carotid artery, including preoperative stent insertion or permanent preoperative balloon occlusion, is usually a fundamental step when dealing with these highly vascularized lesions. Because of the tumor tendency to infiltrate the bony structures, aggressive drilling of the temporal bone is also advised, especially at the level of the petrous apex. Patients affected by uncontrolled recurrences still die of this disease.
A 型颞下窝入路是处理复发性鼓室 - 颈静脉球副神经节瘤的最佳方法,因为面神经改道对于到达颈内动脉区域至关重要,而复发性肿瘤很可能发生在此处。当颈静脉球内侧壁有肿瘤浸润时,保留较低颅神经功能是不可行的;任何神经解剖尝试都会增加残留部分肿瘤的风险。正确处理颈内动脉,包括术前置入支架或术前永久性球囊闭塞,通常是处理这些血管高度丰富病变的基本步骤。由于肿瘤有浸润骨结构的倾向,因此也建议积极磨除颞骨,尤其是在岩尖水平。受无法控制的复发影响的患者仍会死于这种疾病。
