Cone Beam Computed Tomography in observing the presence and location of canalis sinuosus.

Abstract

Cone Beam Computed Tomography (CBCT) was used to observe and describe the distribution of canalis sinuosus (CS) in the Chinese population and the location of CS in the maxillary alveolar bone, so as to help oral surgeons evaluate the intraoperative risk and prognosis before maxillary surgery and reduce the complications caused by the injury of this structure in anterior surgery. CBCT images of 600 patients admitted from 2021 to 2022 were collected to observe the anatomical structure of CS in the maxillary region. The following parameters were recorded: age, sex, number of CS, left and right distribution of CS, CS diameter, and location. Statistical analysis was performed on all of the collected data. The discovery rate of CS in this study was 59.75%, and it is commonly found in the lateral incisor area (64.82%). No significant difference can be found in the presence and number of CS in different gender and age groups (p>0.05). The use of high-resolution CBCT before implantation is of irreplaceable significance in the diagnosis and analysis of CS, which is conducive to reducing implantation complications and failure rate. The incidence of CS was independent of age or sex, while the location of CS was statistically significant.
