To compare and correlate the maxillary sinus dimensions and basal bone height among various facial patterns using CBCT for advanced diagnosis and treatment planning in Orthodontics. 66 CBCT images within age group of 18-30 years were divided into horizontal (Group 1), average (Group 2) and vertical (Group 3) facial growth patterns. Maxillary sinus dimensions were compared and correlated in all three groups. The sinus height and basal bone height were recorded at 3 locations-between 1 premolar and 2 premolar (PM1-PM2), between 2 premolar and 1 Molar (PM2-M1) and between 1 and 2 molar (M1-M2). Overall reduction in sinus height and significantly reduced sinus volume was seen in Group-1. Longest maxillary sinus height in M1-M2 region and shortest in PM1-PM2 region was seen in Group-3. The basal bone height in PM1-PM2 region was significantly longer in Group-3 than in Group-1(p<.05).Shortest basal bone height in M1-M2 region was seen in Group-3. A significant negative correlation was seen between the maxillary sinus height and the basal bone height in Group-1 and Group-3(p<.05). There is a correlation between the maxillary sinus height and basal bone height with that of facial pattern which needs to be considered during orthodontic treatment planning and while carrying out facial growth modification procedures in younger patients.
使用 CBCT 比较和关联不同面型的上颌窦尺寸和基骨高度，以进行正畸的高级诊断和治疗计划。将年龄组为 18-30 岁的 66 个 CBCT 图像分为水平型（第 1 组）、平均型（第 2 组）和垂直型（第 3 组）面部生长模式。比较并关联所有三组的上颌窦尺寸。记录窦高和基骨高在 3 个位置的数值：1 号前磨牙和 2 号前磨牙之间（PM1-PM2）、2 号前磨牙和 1 号磨牙之间（PM2-M1）以及 1 号磨牙和 2 号磨牙之间（M1-M2）。第 1 组的窦高总体减少，窦腔体积显著减少。第 3 组的 M1-M2 区域上颌窦最长，PM1-PM2 区域最短。第 3 组的 PM1-PM2 区域基骨高度明显长于第 1 组（p<.05）。第 3 组的 M1-M2 区域基骨高度最短。第 1 组和第 3 组的上颌窦高度与基骨高度呈显著负相关（p<.05）。上颌窦高度和基骨高度与面型之间存在相关性，这在正畸治疗计划和对年轻患者进行面部生长改建时需要考虑。
