Objective: To identify and describe the morphology and location of the canalis sinuosus (CS) and make correlations with gender, age, and distance of this canal to important adjacent structures on the region, thus mapping the anatomy of this structure.
Methodology: A total of 100 cone beam computed tomography (CBCT) examinations were collected from the files of a dental clinic in the Municipality of Belém, Pará, Brazil, and analyzed to identify the site of bifurcation, the diameter of CS right after such bifurcation and in its terminal portion as well as the direction of its course and the distance to the alveolar bone crest region. The anatomical views were evaluated using InVivoDental software on sagittal, axial, and coronal sections, and the results were submitted to Fisher's exact test, Kendall correlation coefficients, Mann-Whitney tests, and T tests.
Results: CS was present in 88 % of the sample. There were no statistically significant changes in the presence of CS regarding gender, age and direction of course. A strong positive correlation between CS's diameter on its initial and terminal portions was observed (p < 0.0001). There was a statistically significant change in the distance to alveolar bone crest related to gender, which is higher in men (p = 0.0303).
Conclusion: In the sample, CS was frequent and similar in both genders, with course distance to the alveolar bone crest and termination in different locations that ought to be analyzed on CBCT prior to surgical procedures.

Background: Careful anatomical investigation of canalis sinuosus (CS) is essential to prevent damage to blood vessels and nerves in this area during surgical procedures, such as placing dental implants in the anterior maxillary region. This study investigated the relationship and distance between the CS and its adjacent structures.
Methods: A total of 400 cone-beam computed tomography (CBCT) images of Iranian adults aged 20-86 years were included in this retrospective study.

Objective: To evaluate canalis sinuosus (CS) and accessory canalis sinuosus (AC) morphology and their relationship with the impacted canine on cone-beam computed tomography (CBCT) images.
Methods: The diameter and location of the CS, its distance from the nasal cavity (NC-CS), its distance from the buccal cortical plate (BC-CS), and its distance from the alveolar ridge crest (AR-CS) were evaluated on 1000 CBCT scans. The prevalence and termination of AC and the presence of impacted canines were also evaluated.

Article Synopsis
- The study highlights the importance of cone-beam computed tomography (CBCT) in identifying anatomical structures before dental implant procedures.
- CBCT images of 500 adult patients, evaluating variations in structures like the nasopalatine canal and antral alveolar artery, showed specific patterns in both genders.
- The conclusion emphasizes that using CBCT can significantly reduce complications during dental implants by helping dentists understand anatomical relationships before treatments.

Background: While the nasal fossa and nasopalatine canal are recognized limitations for immediate implants in esthetic areas, the canalis sinuosus (CS) and its branches have been largely overlooked. Neglecting this anatomy can lead to sensory issues, pain, and implant failure underscores the necessity of meticulous pre-surgical assessment and planning to mitigate risks and ensure implant success. This case highlights the need for comprehensive pre-surgical evaluation and precise planning to minimize these complications and ensure successful implant outcomes in this scenario.

The canalis sinuosus, a canal containing the anterior superior alveolar nerve bundle, originates from the infraorbital canal and extends along the maxillary sinus and nasal cavity edges to the anterior maxilla. It was once regarded as an anatomical variation. However, with the widespread application of cone beam computed tomography (CBCT), the detection rate of canalis sinuosus in the population has increased.
