摘要
Abstract
BACKGROUND:In order to avoid related complications and to facilitate the choice of surgical approaches, it is particularly important to understand the anatomic characteristics of the maxil ary sinus before maxil ary sinus augmentation. OBJECTIVE:To investigate the anatomic characteristics of human maxil ary sinus based on cone-beam CT imaging for providing some reference related to sinus floor elevation and implant insertion. METHODS:Cone-beam CT imaging data from 249 adults were selected and analyzed. The length (internal wal ) and width of the maxil ary sinus were measured, and the incidence of maxil ary sinus septa and the characteristics of the maxil ary sinus vessels were investigated and analyzed preliminarily. RESULTS AND CONCLUSION:The mean length (internal wal ) and width of maxil ary sinus were (32.0±3.81) and (21.70±5.16) mm, respectively. No significant differences were noted in the length and width of maxil ary sinus based on sex or age (P>0.05). The incidence of maxil ary sinus septa was 33%(78/249). Moreover, the distribution and characteristics of the maxil ary sinus vessels could be seen clearly and accurately on cone-beam CT three-dimensional images. These findings indicate that cone-beam CT images can show anatomical structures of the maxil ary sinus ful y and accurately, and the use of cone-beam CT is advantageous and mandatory to determine surgical indications and approaches, and avoid or reduce the incidence of surgical complications of maxil ary sinus floor elevation.关键词
