对额窦炎治疗的历史虽长,目前公认以开放额窦清理病变并重建持久而有效的鼻额管通道为最合生理要求的术式,能恢复额窦的通气和引流功能,但如何才能建立持久、有效通道的问题,仍未完全解决,以致慢性额窦炎术后复发率高达20～40％,失败的主要原因是鼻额管通道的闭锁和狭窄。为术中建立通道曾采用生物材料(如鼻粘膜,粘骨膜瓣,脱钙骨,冷冻干燥处
Although the history of frontal sinusitis is long, it is generally acknowledged that opening the frontal sinus to clear the pathological changes and rebuilding a long-lasting and effective nasal tube channel is the most physiologically demanding surgical procedure that can restore the ventilation and drainage functions of the frontal sinus. However, The establishment of long-lasting, effective access to the problem has not yet been fully resolved, resulting in chronic sinusitis postoperative recurrence rate as high as 20 to 40%, the main reason for the failure is the nasal tube channel atresia and stenosis. For the establishment of intraoperative channel has used biological materials (such as nasal mucosa, mucoperiosteal flap, decalcified bone, freeze-dried at
