Abstract
Maxillitis is treated medically or surgically. However, postoperative cyst of the maxillary sinus, cyst of the cheek have been described as iatrogenic disorders since radical operation. Complete removal of the mucosa of the maxillary or the ethmoidal sinus is impossible in sinusitis because of the anatomical positions of the ethmoidal sinus. However, the disease was reported to be uncurable in the patients even when radical demucosation of the sinus was performed during operation of maxillary cancer. These results indicate that surgical procedures are not appropriately selected for different conditions. One of the causes sinusitis is closure of the natural opening and the indications of construction are considered to be related to the air resistance in sinusitis to surgical treatments. Moreover, the intranasal morphology, function of the mucosa of the paranasal sinuses and the extent of the obstruction of the natural opening of the maxilla must be accurately evaluated before determination of the treatment. Whereas, the maxillary sinus ostium was enlarged and the middle meatus opened, instead of establishing a counter opening in the inferior meatus. The purposes of the operation are to relieve symptoms and prevent recurrence of sinusitis. Any surgical procedure to achieves these aims are useful. We present a new surgical technique, Asai's method that evaluate these purposes.
