This study aimed to evaluate the morphological and dimensional variations of the frontal air sinuses in a group of adolescent Caucasians and Chinese with different skeletal malocclusions in both genders.
This retrospective study included 290 adolescent Caucasians and Chinese patients with 145 each. Each sample included 90 females and 55 males and was categorized based on ANB angle in reference to each population norms into 65 skeletal class I, 50 skeletal class II, and 30 skeletal class III malocclusions. All linear, angular, and surface area measurements of the frontal air sinuses were evaluated using lateral cephalometric radiographs and calculated using Winceph version 8 software. The frontal air sinus parameters were compared between genders and the two ethnic groups using an independent sample t-test. ANOVA with Tukey's post hoc tests were used to compare the frontal air sinus parameters between the three skeletal malocclusions.
The frontal air sinus width and surface area were found to be significantly greater in Caucasians when compared with Chinese patients. According to gender, the frontal air sinus length, width, and surface area, as well as the glabella convexity, were greater in males than females, while the frontal air sinus index (length/width) was significantly greater in females than males in both ethnic groups. In both ethnic groups, the frontal air sinus surface area was significantly greater in skeletal class III malocclusion when compared to skeletal class I and class II malocclusions in Caucasians (P = 0.0022) and Chinese (P = 0.0097). There was a weak-to-moderate correlation between the frontal air sinus parameters and the nasio, sella, and glabella positions (R = -0.56 to 0.62).
The frontal air sinus dimensions and surface area varied greatly in between ethnic groups, genders, and malocclusion types. The frontal air sinus parameters were correlated with nasion, sella, and glabella positions.
These findings could assist orthodontists, ENT specialist, and forensic medical investigators to focus on the size of frontal sinus during treatment planning, the relationship between the size of frontal air sinus and malocclusions, and age determination.
本研究旨在评估不同性别、不同骨骼错颌畸形的白种人和中国青少年的额窦形态和尺寸变化。
本回顾性研究纳入了 290 名白种人和中国青少年患者，每组 145 名。每个样本包括 90 名女性和 55 名男性，并根据每个群体的 ANB 角参照其正常范围分为 65 例骨骼 I 类、50 例骨骼 II 类和 30 例骨骼 III 类错颌。使用侧位头颅侧位片评估额窦的所有线性、角度和表面积测量值，并使用 Winceph 版本 8 软件进行计算。使用独立样本 t 检验比较性别和两个种族组之间的额窦参数。使用方差分析（ANOVA）和 Tukey 事后检验比较三种骨骼错颌类型之间的额窦参数。
与中国患者相比，白种人的额窦宽度和表面积明显更大。根据性别，男性的额窦长度、宽度和表面积以及额结节凸度大于女性，而在两个种族组中，女性的额窦指数（长度/宽度）明显大于男性。在两个种族组中，与骨骼 I 类和 II 类错颌相比，骨骼 III 类错颌的额窦表面积在白种人中（P = 0.0022）和中国人中（P = 0.0097）均显著更大。额窦参数与鼻根、蝶鞍和额结节位置之间存在弱到中度相关性（R = -0.56 至 0.62）。
额窦的尺寸和表面积在种族、性别和错颌类型之间存在很大差异。额窦参数与鼻根、蝶鞍和额结节位置相关。
这些发现可以帮助正畸医生、耳鼻喉科专家和法医调查人员在治疗计划中关注额窦的大小、额窦大小与错颌的关系以及年龄确定。
