为了探讨副鼻窦肿瘤累及前颅底的手术入路及颅底修复的方法，分析了７例鼻窦肿瘤累及前颅底而行颅底切除的病例资料。采用单一面部切口者２例，颅面联合入路者５例。颅底缺损２ｃｍ×３ｃｍ至６ｃｍ×５ｃｍ。修复采用开颅时形成的颅骨膜瓣２例、颞肌瓣２例、带蒂前额皮瓣１例，未修复２例。近期发生并发症２例（脑脊液漏和鼻旁切口裂开各１例），未发生脑膜膨出。全组有５例已存活３～５８个月。结果表明前颅底手术是安全的，前颅底缺损不一定要行骨质的修复。
In order to discuss the surgical approach to the anterior skull base involving the paranasal sinus tumor and the method of skull base repair, the cases of cranial basement resection in 7 cases of sinus tumors involving the anterior skull base were analyzed. There were 2 cases with single facial incision and 5 cases with combined craniofacial approach. Skull base defect 2cm × 3cm to 6cm × 5cm. Two cases of cranial flap formed when craniotomy was established, two cases of temporal muscle flap, one case of pedicle pedicle flap, and two cases without repair. Two cases of recent complications (cerebrospinal fluid leakage and nasal incision split in 1 case), no occurrence of meningeal bulging. Five patients in the whole group have survived for 3 to 58 months. The results show that anterior skull base surgery is safe, anterior skull base defect does not necessarily require bone repair.
