Frontal sinus growth is gradual and lasts until post-puberty. However, the influence of biomechanical stimuli, such as orthodontic treatment, on frontal sinus development after the growth period has ended remains unclear. This study was designed to elucidate the impact of orthodontic treatment on the frontal sinus morphology of adult females. Sixty women were included and divided into three groups, based on the Frankfort mandibular plane angle. All participants underwent computed tomography and lateral cephalometry before and after treatment. Although two participants exhibited frontal sinus agenesis, most exhibited a bilaterally symmetric frontal sinus without fusion. The frontal sinus width and height were almost similar, irrespective of the vertical skeletal pattern, where the frontal sinus depth was significantly larger in the average mandibular plane angle group than in the low- and high-angle groups. Furthermore, the sinus volume in the low-angle group was likely smaller than that in the average and high-angle groups. On comparing pre-treatment and post-treatment measurements, minimal or no changes to the frontal sinus dimension were detected after treatment. In conclusion, orthodontic treatment did not affect frontal sinus development after the end of growth.
额窦生长是渐进性的，持续到青春期后。然而，生物力学刺激（如正畸治疗）对生长期结束后额窦发育的影响仍不清楚。本研究旨在阐明正畸治疗对成年女性额窦形态的影响。纳入60名女性，根据法兰克福下颌平面角分为三组。所有参与者在治疗前后均接受了计算机断层扫描和头颅侧位测量。虽然两名参与者表现为额窦发育不全，但大多数表现为双侧对称的额窦且无融合。无论垂直骨骼类型如何，额窦的宽度和高度几乎相似，其中平均下颌平面角组的额窦深度明显大于低角组和高角组。此外，低角组的窦体积可能小于平均角组和高角组。比较治疗前和治疗后的测量结果，治疗后未检测到额窦尺寸有最小变化或无变化。总之，生长结束后正畸治疗不影响额窦发育。
