    Introduction: The objective of this study was to evaluate a possible relationship between maxillary sinus volume (MSV) and the diameter and length of the nasolacrimal canal (NC) using cone beam computed tomography (CBCT) data. Methods: In this retrospective study, CBCT scans of 93 patients were evaluated. The maxillary sinuses and NCs were evaluated separately using Fujifilm-Synapse 3D software. 186 measurements of NC and maxillary sinuses were made in 93 patients. Results: The total mean patient age was 38.2 ± 15.2 years. There were no significant differences between genders in terms of MSV, length, and diameter of NC. No statistically significant differences were found between the two sides in terms of MSV, length, and diameter of NC. While a negative correlation was detected between MSV and NC diameter, a positive correlation was found between MSV and NC length. Discussion and Conclusion: As the maxillary sinus medial wall forms the lateral border of the nasal cavity, the recognition and preservation of the nasolacrimal canal is essential for better postoperative results in surgical procedures to be applied to this area. In our study, it was found that as MSV increased, the diameter of the NC decreased and its length increased.
