目的:经颅底扩大翼点入路开颅术是将翼点开颅术向颅底方向的进一步扩大,包括眶上翼点入路、颧弓翼点入路和眶翼弓入路。本文探讨该入路的手术方法和适应证。方法:经扩大翼点入路切除颅底肿瘤30例。观察术中显露情况及手术效果,并就该入路的手术方法和适应证进行探讨。结果:所有病例术中病灶显露良好,无1例出现脑牵拉损伤。肿瘤全切除25例,次全及大部分切除5例。术后死亡1例,其余病例均无严重并发症。结论:经扩大翼点入路切除颅底肿瘤具有显露好、脑牵拉轻的优点,适用于中颅底、鞍旁肿瘤、颅眶沟通瘤及部分自中颅底向后颅底或颅外生长的肿瘤。
OBJECTIVE: Transcranial expansion of pterional approach craniotomy is the further expansion of pterygiocervical craniotomy to the skull base, including supraorbital pterional approach, zygomatic arch pterional approach and orbital wing arch approach. This article discusses the surgical approach and indications for this approach. Methods: 30 cases of skull base tumors were excised by enlarging pterional approach. Observe the situation revealed in the operation and the effect of surgery, and to discuss the surgical approach and indications for the approach. Results: In all cases, intraoperative lesions were well revealed, and none of the cases had traumatic brain injury. Tumor resection in 25 cases, subtotal and most of the resection in 5 cases. One patient died after operation, and the remaining cases had no serious complications. Conclusion: The expanded pterional approach to resect the skull base tumors has the advantages of good exposure and light traction of the brain. It is suitable for mid-skull base, parasellar tumor, cranial orbital tumor, and part of the cranial base from the mid-skull to the posterior skull base or extracranial Growing tumor.
