This article presents a simple, inexpensive method for precisely locating the floor of the maxillary sinus, as well as the presence of any septa, at the time of sinus augmentation surgery. Using an anesthesia light wand placed transnasally to illuminate the sinus, the surgeon can reliably elevate the lateral maxillary wall overlying the sinus with relative ease without fear of placing the osteotomy cuts too far from the sinus floor. The same procedure can be used postoperatively to evaluate the density of the bone graft placed into the sinus prior to closure.
本文介绍了一种简单、廉价的方法，可在鼻窦增高手术时精确确定上颌窦底的位置以及是否存在任何间隔。通过经鼻放置麻醉灯棒照亮鼻窦，外科医生能够相对轻松地可靠抬起覆盖鼻窦的上颌骨外侧壁，而不必担心截骨切口离鼻窦底太远。相同的操作可在术后用于评估在关闭切口之前植入鼻窦的骨移植物的密度。
