既往侵犯筛窦、筛板的恶性肿瘤均经面手术,此术式操作困难,病变常分块切除且不完全。联合颅面进路由于接近肿瘤所在部位,能广泛地暴露前颅底,保护脑组织,彻底切除筛窦恶性病变。作者对21例累及前颅底的恶性病变经颅面径路行切除术。鳞癌8例、软骨肉瘤3例、黑素瘤2例、基底细胞癌2例、腺癌2例、低分化癌2例、恶性神经鞘膜瘤和恶性血管外皮细胞瘤各1例。随访41个月,生存率为
Past violations of the ethmoid sinus, sieve of the malignant tumors are surgically operated, this operation is difficult, the lesions often sub-block resection and incomplete. Due to the approach of the craniofacial approach to the site of the tumor, the craniofacial approach can extensively expose the anterior skull base, protect the brain tissue, and thoroughly remove the ethmoidal malignant lesions. The author of 21 cases of malignant lesions involving the anterior skull by craniofacial route resection. Squamous cell carcinoma in 8 cases, chondrosarcoma in 3 cases, melanoma in 2 cases, basal cell carcinoma in 2 cases, adenocarcinoma in 2 cases, poorly differentiated carcinoma in 2 cases, malignant nerve sheath tumor and malignant hemangiopericytoma in 1 case. Follow-up 41 months, the survival rate was
