ABSTRACT

Objective:

To observe the anatomic variations and lesions of maxillary sinus by CBCT before sinus augmentation in Chinese patients with edentulous posterior maxilla.

Methods:

589 participants with 666 sinuses were enrolled in this study. The anatomic variations and lesions of maxillary sinus were examined by CBCT prior to sinus augmentation surgery.

Results:

In all 666 sinuses, the prevalence of septa was 30. 48%, membrane thickness ≤2 mm was 60. 36%, the average thickness of the lateral wall was (1. 38 ± 0. 05) mm, the prevalence of posterior superior alveolar artery in the sinus was 66. 52%, the average diameter of the artery was (0. 98 ± 0. 03) mm, the discontinuity of the sinus floor was 4. 35%, the mean width of maxillary sinus was (14. 20 ± 0. 19) mm, and the prevalence of cyst was 11. 41%.

Conclusion:

CBCT can reveal the sinus diversity and provide the information for the safe and effective sinus augmentation.
