经中颅底硬膜间入路切除中后颅窝哑铃型三叉神经鞘瘤
Middle cranial fossa interdural approach for dumbbell-shaped trigeminal schwannomas
摘要
Abstract
Objective To investigate the effect and indication of the middle cranial fossa interdural approach for dumbbell-shaped trigeminal schwannomas .Methods The clinical data of 7 patients with dumbbell-shaped trigeminal schwannomas underwent through middle cranial fossa interdural approach from October , 2009 to November , 2014 were analyzed retrospectively .Tumors were classified into three types based on their distribution over the petrous ridge ( Mp type,MP type and mP type ) .The middle cranial fossa interdural approach was selected for type Mp and MP .The extent of tumor resection , cranial nerve outcome , approach-related morbidities , and recurrence of the tumors were documented .Results Of 7 patients,5 were Mp and 2 MP.MRI of postoperative one day showed that total resection was achieved in all patients .There was no operative mortality or new permanent neurological deficits .Improvement of the preoperative cranial nerve dysfunction was observed in 4 patients and 3 unchanged .Postoperative subcutaneous liquid collection and intracranial infection developed in 1 patient , which was managed with lumbar drain and anti-infective therapy .New postoperative atrophy of the temporalis muscle was observed in 1 patient .The tumors did not recur in 7 patients who were followed up from 12 to 60 months.Conclusion The middle cranial fossa interdural approach could be an effective method for removing dumbbell-shaped trigeminal schwannomas , particularly for type Mp and MP ,the direct injury to brain ,cranial nerve and vascular was avoided by this approach ,so this approach produces no further impairment ,less complication .关键词
