颈静脉孔神经鞘瘤的显微外科治疗

目的　研究颈静脉孔神经鞘瘤的手术切除效果。　方法　回顾性分析采用显微外科手术治疗颈静脉孔神经鞘瘤２０ 例，其中 Ａ 型肿瘤位于桥小脑角１２ 例； Ｂ型肿瘤原发于颈静脉孔，向颅内生长３ 例，采用乳突后枕下或后正中钩型切口开颅； Ｃ 型肿瘤位于颅外，并向颈静脉孔生长１ 例， Ｄ 型肿瘤由颈静脉孔向颅内外生长，呈哑铃型４ 例，取颈乳突联合入路。　结果　肿瘤全切除１１ 例，次全切除９ 例次，大部切除５ 例次，无手术死亡率。　结论　根据肿瘤生长方式选择良好显露肿瘤的手术入路是切除肿瘤的关键，而防止脑神经损伤是切除肿瘤的重要环节

Microsurgical treatment of jugular foramen schwannomas

Objective To observe the effectiveness of surgical treatment for patients with schwannomas of the jugular foramen Methods Twenty patients with schwannomas of the jugular foramen had undergone microsurgical operations in our hospital The tumor were classified into four types: Type A, a tumor primarily at the CPA (12 cases); Type B, a tumor primarily at the jugular formen with intracranial extension (3 cases); Type C, a primarily extracranial tumor with extension into the jugular foramen (1 cases) and Type ial components (4 cases) A retro mastoid suboccipital or posterior median hook shape craniectomy was performed for Type A and B tumors; and a combined cervical mastoidectomy for Type C and D Results Total tumor removal was achieved in 11 case times, subtotal removal in 9 case times, and greater part removal in 5 cases times All 20 patients were survived after operation Conclusion The key of tumorectomy is the choice of surgical approach by the type of tumor extension And during the operation, it is very important that saving the function of the remaining lower cranial nerves
