Canalis Sinuosus

Abstract

The Sinuous Canal (SC) is a bony canal in the maxilla that branches f rom the inf raorbital canal and ends laterally at the anterior nasal spine. Under normal conditions, the SC has a diameter of less than 1 mm and a total length of 5.5 cm, it contains the anterosuperior alveolar neurovascular bundle that irrigates, drains and innervates the canines and upper incisors, gums and mucosa in the area, the meatus lower nasal, anterior part of the maxillary sinus and nasal septum. In this report, a case of CS with ramifications and bifurcation in the palatal area of the anterior teeth, in a 22-year-old female patient, referred to the radiological center for evaluation of third molars by cone beam computed tomography (CBCT) is described by imaging. A sequential evaluation of transaxial views was performed in the premaxilla. The coronal views showed the right and left accessory conductors emerging from the floor of the nostrils in an orientation to the alveolar rim, highlighting the presence of a palatal branching of teeth 1.1 and 2.1. The CBCT will identify the location of the anatomical variant, path, caliber, and relationship with adjacent structures, to obtain a more precise location that avoids complications of clinical procedures, as well as to rule out false diagnoses of pathologies associated with neighboring teeth.
