In order to expose the orbital floor, ligation of the maxillary artery, conservative treatment of nasal sinusitis invalid treatment, removal of foreign body, tooth root remnants, maxillary sinus ectopic teeth, with cysts and benign sinus tumors, etc., exposed oral good Road for the indication. In the past, surface-nasal surgery, pioneered by Caldwell and Luc, has been considered a standard maxillary sinus surgery worldwide. Subsequent studies have shown that Caldwell-Luc surgery does not always lead to recovery, but chronic neuralgia-like conditions and obstructive cysts may occur postoperatively. To this end, proposed
