Anatomical structure of human maxillary sinus: Cone-beam CT analysis

Abstract

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 maxillary sinus before maxillary sinus augmentation.
OBJECTIVE: To investigate the anatomic characteristics of human maxillary 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 wall) and width of the maxillary sinus were measured, and the incidence of maxillary sinus septa and the characteristics of the maxillary sinus vessels were investigated and analyzed preliminarily.
RESULTS AND CONCLUSION: The mean length (internal wall) and width of maxillary sinus were (32.0±3.81) and (21.70±5.16) mm, respectively. No significant differences were noted in the length and width of maxillary sinus based on sex or age (P > 0.05). The incidence of maxillary sinus septa was 33% (78/249). Moreover, the distribution and characteristics of the maxillary 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 maxillary sinus fully 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 maxillary sinus floor elevation.
