“…Shelley et al11 reported a case in which a well-defined radiolucency simulating a pathologic lesion was recognized around the top-left canine apex. Further radiographs and detailed clinical examinations proved that it was a variation of the CS.…”

PurposeThe nasopalatine canal is a well-known, important anatomical structure in the anterior maxilla, but this region contains many accessory canals. The canalis sinuosus (CS) is one of these canals; it contains the anterior superior alveolar nerve, along with veins and arteries. The purpose of this study was to evaluate the CS using conebeam computed tomography (CBCT) in patients with maxillary impacted canines.Materials and MethodsA total of 111 patients admitted to the Istanbul Medipol University School of Dentistry for the exposure, orthodontic treatment, and/or extraction of an impacted canine were included in this study. CBCT images were obtained for these patients under standard conditions. Axial, coronal, and sagittal sections were evaluated to assess the prevalence of CS, the direction and diameter of the canal, its relation with the impacted canine, and its distance from the alveolar crest. Further, possible correlations with patient gender and age were analyzed.ResultsThe CS could be detected bilaterally in all the evaluated tomography images. The mean canal diameter was significantly larger in males than in females (P=.001). The CS ran significantly closer to the impacted canine when the canal was located horizontally (P=.03). Variations of the canal, such as accessory canals, were identified in 6 patients.ConclusionCS is an anatomical entity that may resemble periapical lesions and other anatomical structures. Evaluation with CBCT prior to surgical procedures in the anterior maxilla will help to prevent overlooking such anatomical structures and to decrease possible surgical complications.

“…It has been stated that the palate may be pierced by many small foramina and marked by pits for palatine glands (Warwick & Williams 1973). However, despite a few cases reported in the literature (Kohavi 1994;Shelley et al 1999;Temmerman et al 2011), the occurrence of anatomical variations involving AFP region with clinically relevant diameters and their association with bony canals that may contain major neurovascular content has not been systematically assessed.…”

“…This canal was named "canalis sinuosus" by Jones (1939), and this term was suggested due to its doubled curved course. Few subsequent authors have referred to this canal (Warwick & Williams 1973;Heasman 1984;Shelley et al 1999;Balaji 2007) and apparently not much attention has being given to this structure in recent literature. However, this is a rather wide canal and carries not only the ASA nerve which is a considerable nerve in diameter (McDaniel 1956) but also the ASA artery.…”

“…& ZÚÑIGA, J. R It is also associated with complications by direct or indirect injury to the anterior superior alveolar neurovascular bundle, such as intraoperative bleeding, changes in the overall sensitivity of the territory of ASAN, and difficulty in osseointegration of implants (Arruda et al, 2017). For example, Shelley et al (1999) reported a case in which an abnormal extension of this canal was mistaken for a periapical lesion on an intraoral x-ray. Vâlcu et al reported the anatomic variation of a canal in the hard palate that was interpreted as a possible aberrant fissure of the maxilla, but may have been an anatomic variation of the CS.…”

Frequency of Canalis Sinuosus and its Anatomic Variations in Cone Beam Computed Tomography Images

et al. 2019

The aim of this paper was to determine the frequency of Canalis Sinuosus (CS) and its anatomic variations. A total of 236 cone beam computed tomography (CBCT) images were studied. Characteristics of the canal such as its form, pathway and diameter were analyzed. The CS was clearly visualized in 100 % of the images with variations in the canal observed in up to 46 % of the cases. In 79 % of the cases the variation was found to be bilateral. The most common variation was an increase in the diameter (> 1mm) of the CS. Considering that the anterior region of the middle third of the face is a common place for clinical interventions, this study supports the need to perform a thorough evaluation of the maxillary region prior to clinical interventions in order to prevent complications such as direct or indirect injury to the anterior superior alveolar neurovascular bundle contained within the CS.
