额窦引流通道的解剖结构复杂、变异多,使额窦手术被认为是目前鼻内镜手术中难度最大和最富挑战性的手术[1]。Friedman等[1]认为手术成功的关键在于辨认额窦的自然引流通道。本文对额窦引流通道(frontal sinus drainage pathway,FSDP)相关解剖结构的研究历史及现状做一综述。1额 The anatomical structure of the frontal sinus drainage channel is complex and has many variations, making the frontal sinus surgery the most difficult and challenging surgery in endoscopic sinus surgery [1]. Friedman et al [1] that the key to the success of surgery is to identify the natural sinus frontal drainage channels. This article reviews the history and current status of the research on the anatomy of the frontal sinus drainage pathway (FSDP). 1 amount
