The infraorbital foramen (IOF) is a critical structure on the maxilla transmitting the infraorbital nerve and vessels. Precise knowledge of its dimensions is essential for clinical procedures. This study investigated the vertical and horizontal diameters of the IOF and their correlation in a Bangladeshi population. This cross-sectional, analytical study examined 300 dry human maxillae (148 left and 152 right) collected from the Department of Anatomy of Mymensingh Medical College (MMC) and Community Based Medical College, Bangladesh (CBMC,B), Mymensingh, Bangladesh. Maximum vertical and horizontal diameters were measured using digital Vernier calipers. Pearson's correlation coefficient assessed the relationship between dimensions. The mean vertical diameter was 2.98±0.51 mm (left) and 2.95±0.50 mm (right), with ranges of 1.76–4.89 mm and 1.83–4.17 mm respectively. The mean horizontal diameter was 4.39±0.92 mm (left) and 4.44±0.96 mm (right), ranging from 2.13–7.28 mm. A significant positive correlation was observed between vertical and horizontal diameters on both sides (left: r=0.442, p<0.001; right: r=0.386, p<0.001). This study establishes baseline dimensional data for the IOF in the Bangladeshi population. The significant correlation between dimensions suggests predictable morphological patterns that may assist clinicians in surgical planning and regional anesthesia procedures.
