OBJECTIVE: To observe the gasification of the maxillary sinus which might affect the vision of the maxillary sinus surgery with endoscope.
METHOD: The diameters of 2 000 maxillary sinus were observed and measured hy normal sinus CT scan. The maxillary sinus were then genotyped with the data.
RESULT: Morphology of the medial wall of maxillary sinus played an important role in maxillary sinus surgery. According to the horizontal position CT data, the middle part of maxillary sinus medial wall included two shapes: 857 triangle (85.7%) and 143 semicircular (14.3%). According to the coronal CT data, the middle part of maxillary sinus medial wall varied a lot, there were also two shapes of them: 341 convex type (31.1%) and 659 straight type (65.9%). In contrast, the former and back parts varied a little. Therefore, we genotyped the maxillary sinus according to the morphology of maxillary sinus medial wall and the gasification level. There were 3 types of our genotyping: 662 of I type (66.2%), 265 of II type (26.5%), 73 of III type (7.3%).
CONCLUSION: The medial wall of maxillary sinus should be considered before the surgery of nasal endoscopy because of the great affections of which to endoscopy version.
