Abstract: Objective To evaluate maxillary sinus lateral wall thickness of different population by using cone-beam computed tomography(CBCT), in order to provide anatomical basis for operation guidance, preoperative risk assessment and surgical risk in operation which is closely related with the maxillary sinus lateral wall thickness. Methods Using Planmeca Romexis 3.1.0.R software to evaluate the 3D image data in all 331 samples which maxillary sinus lateral wall was taken from 15、16、17、25、26、27 in radiology department of People’s Hospital of Xinjiang Urgur Autonomous Region from April 2013 to October 2014. The data was analyzed with SPSS 17.0 software package. Results Male or female, Han people or Uyghur people, different age groups and presence or absence of tooth the maximum thickness of lateral wall were all almost located at 16 or 26. The minimum thickness of lateral wall was 0.5 mm, located at the second molar. The maximum thickness of lateral wall was 10.92 mm, located at the first molar. In the same location, between different gender, races, age groups and presence or absence of tooth, there were no significant differences(P<0.05), except the left second molar between male and female. Conclusion CBCT can precisely measure maxillary sinus lateral wall thickness. Age, gender, race and presence or absence of tooth have little influence on the thickness of lateral wall, however, there are large differences in the thickness of lateral wall between different location and individual.
