Abstract　： [Abstract] Objectives: This study aimed to examine the relationship between the maxillary sinus size and different skeletal patterns in adult Korean individuals using cone-beam computed tomography (CBCT). Materials and Methods: We enrolled 56 adult Korean individuals (mean age, 26.04 +- 6.58 years; 21 males, 35 females) and classified them into three antero-posterior skeletal patterns (skeletal Class I, Class II, and Class III) according to the A point-nasion-B point angle (ANB) - Class I (-1°<- ANB < 4°), Class II (ANB >- 4°), and Class III (ANB < -1°) - and three vertical skeletal patterns (hypodivergent, normodivergent, and hyperdivergent) according to the mandibular plane angle (MP) - hypodivergent (MP <- 23°), normodivergent (23°< MP < 30°), and hyperdivergent (MP >- 30°) as measured through CBCT images. The maxillary sinus width and depth were measured using a measurement template and automated processing with reference to the methods reported in previous studies. Differences in the size of the maxillary sinus (maxillary sinus width and depth) among the different skeletal patterns (three anteroposterior skeletal patterns and three vertical skeletal patterns) were statistically analyzed using one-way analysis of variance with the post-hoc Tukey test. Results: There were no statistically significant differences in the maxillary sinus width and depth among the anteroposterior skeletal patterns. However, a statistically significant difference (P < 0.05) in the maxillary sinus width was observed among the vertical skeletal patterns. In the vertical skeletal patterns, the mean maxillary sinus width increased as follows: normodivergent, hypodivergent, and hyperdivergent. Conclusions: Our results indicate that the vertical skeletal patterns of adult Korean individuals might be associated with the maxillary sinus width.
