Concha bullosa, a common anatomical variation characterized by air-filled cavities in the turbinate bones, can influence sinonasal function and surgical planning. This study aims to evaluate the distribution, laterality, and cranial skeletal type associations of concha bullosa (CB) among patients with confirmed CB findings on computed tomography (CT) scans.
A retrospective cohort study was conducted on 774 patients who underwent cranial and facial CT scans between March 2023 and March 2024. Patients were classified into mesocephalic, brachycephalic, and dolichocephalic groups based on the cephalic index. The distribution and laterality of concha bullosa were assessed using CT scans, and statistical analyses were performed using the Chi-square test, with a significance level set at P < 0.05.
Among CB-positive patients, left-sided concha bullosa was most common (49.48%), followed by right-sided (31.91%) and bilateral (18.6%) involvement. Mesocephalic individuals constituted the largest proportion of CB-positive cases (55.56%), followed by dolichocephalic (22.86%) and brachycephalic (21.57%) individuals. A significant gender difference was observed in the mesocephalic (P = 0.001) and brachycephalic (P = 0.013) groups, with males exhibiting a higher prevalence of right-sided and bilateral concha bullosa.
Concha bullosa distribution varies significantly among cranial skeletal types among CB-positive patients, with mesocephalic individuals exhibiting the highest overall prevalence. Our findings underscore the influence of cranial morphology on the presentation of CB. This insight may enhance radiological evaluation and individualized surgical planning in CB-positive patients.
泡状鼻甲是一种常见的解剖变异，其特征为鼻甲内出现气腔，可影响鼻窦功能及手术规划。本研究旨在评估计算机断层扫描（CT）检查确诊为泡状鼻甲（CB）的患者中泡状鼻甲的分布、侧别及颅骨骨骼类型关联。
对2023年3月至2024年3月期间接受头颅和面部CT扫描的774例患者进行回顾性队列研究。根据头指数将患者分为中头型、短头型和长头型组。利用CT扫描评估泡状鼻甲的分布和侧别，并采用卡方检验进行统计分析，显著性水平设定为P < 0.05。
在CB阳性患者中，左侧泡状鼻甲最为常见（49.48%），其次是右侧（31.91%）和双侧受累（18.6%）。中头型个体在CB阳性病例中所占比例最大（55.56%），其次是长头型（22.86%）和短头型（21.57%）个体。在中头型（P = 0.001）和短头型（P = 0.013）组中观察到显著的性别差异，男性右侧和双侧泡状鼻甲的患病率较高。
在CB阳性患者中，泡状鼻甲的分布在颅骨骨骼类型之间存在显著差异，中头型个体的总体患病率最高。我们的研究结果强调了颅骨形态对CB表现的影响。这一见解可能会加强对CB阳性患者的放射学评估和个体化手术规划。
