Endoscopic techniques for paranasal sinus surgery have allowed detailed and complete removal of sinus disease while promising minimum distress to the patient. The telescopic view of the operative field shows detail of the sinus anatomy and its disease, not possible in earlier transnasal techniques. Several articles document the serious complications seen with the endoscopic surgery. To understand the paranasal sinuses and their relationships to the orbit and cribriform plate, blocks of cadaver heads that included the orbit and paranasal sinuses were whole sectioned. It has been possible to see areas of the cribriform and orbital wall that are at risk to produce cerebrospinal fluid rhinorrhea and orbital complications. At the same time, landmarks for avoiding these complications can be defined to guide the surgeon during this dissection as seen through the endoscope.
鼻旁窦手术的内镜技术能够在确保对患者造成最小痛苦的同时，实现对鼻窦疾病的细致且彻底的清除。手术视野的望远镜式观察展现了鼻窦解剖结构及其疾病的细节，这在早期经鼻手术中是无法实现的。有几篇文章记录了内镜手术中出现的严重并发症。为了了解鼻旁窦及其与眼眶和筛板的关系，对包含眼眶和鼻旁窦的尸体头部进行了整体切片。已经能够看到筛板和眶壁上存在产生脑脊液鼻漏和眼眶并发症风险的区域。与此同时，可以确定避免这些并发症的标志，以便在内镜观察下指导外科医生进行此次解剖。
