Abstract

Background: Palatal surgeries are associated with many complications. Accessory foramina may be a cause of concern. The aim of the present study was to assess the occurrence and to evaluate the anatomical features of accessory palatine foramina and their bony canals using cone beam computed tomography (CBCT).

Materials and methods: The incidence, location, and types of foramina on the palate were evaluated in 170 CBCT scans. Readings from coronal, sagittal, and axial planes were recorded using Planmeca Romexis Viewer 5.4.1.R. computer program. Data were tabulated and evaluated.

Results: Other than nasopalatine, greater and lesser palatine foramina, 278 foramina were observed in the palatal surface of the upper jaw in different locations. New accessory palatine foramina were found posteriorly in 14.71% of the studied scans with wide anatomical variations. Unusual foraminal canals were seen crossing the floor of the maxillary sinus laterally. The incidence of the anterior accessory palatine foramina was 73.53%. Bilateral accessory palatine foramina were found in 43.53% of cases.

Conclusions: Accessory palatine foramina and their bony canals are frequently seen in CBCT with wide anatomical variations. New unusual connecting canals are found passing from palatine foramina to the lateral wall of the maxillary sinus through the sinus floor. These findings should be considered when planning for anesthesia and surgery in the palate.
