前颅底病变可累及额筛窦和鼻腔,由于额下入路、颅面联合入路、鼻侧切开术及面中线翻揭术等损伤较大,少数作者已经开始尝试扩大经鼻入路手术,但是报道少,相关解剖学研究也未开展。本文通过相关的解剖结构观测,结合尸颅手术摹拟,探讨经鼻入路前颅底手术的可行性和实用性,提出预防 Frontal skull base lesions can affect the ethmoid sinus and nasal cavity, due to inferior frontal approach, craniofacial approach, nasal cesarean section and midline ligation and other injuries greater, a few authors have begun to try to expand the nasal approach Surgery, but few reports, the relevant anatomical studies have not been carried out. This article through the relevant anatomical observation, combined with the cadaver surgery simulation to explore the feasibility and practicality of transnasal approach anterior skull base surgery, proposing prevention
