The purpose of this study was to detect the prevalence and characteristics of pneumatization in the roof of the glenoid fossa (PRGF) and articular eminence (PAT) by using cone beam computed tomography (CBCT) images.
CBCT images of 378 patients (756 TMJ) were analyzed to determine the PRGF and PAT. Twenty-eight patients were excluded due to some reasons such as trauma, degeneration, previous surgical operation of temporomandibular joint (TMJ). Pneumatization was detected in 297 of 350 patients, but not pneumatization in 53 patients. Age, gender, laterality (unilateral, bilateral) and lacunarity (unilacunar, multilacunar) were recorded. Unilateral types were also noted as right and left localization. Chi-square test was used to evaluate relationship between pneumatization and gender, lacunarity and laterality.
PRGF and/or PAT were diagnosed in 491 (70%) TMJ components whom 178 (51%) were male and 172 (49%) were female with mean age of 40.38±18.34 years. In total, 103 (35%) of the patients had unilateral and 194 (65%) patients had bilateral pneumatization.
CBCT provides reliable and precise images to detect pneumatization surrounding TMJ structure in comparison to 2D images. Evaluation of TMJ components accurately before surgical intervention is crucial to prevent complication or increase the success of therapy.
本研究旨在通过锥形束 CT（CBCT）图像检测髁突窝顶（PRGF）和关节结节（PAT）的气化情况及其特点。
对 378 例患者（756 例 TMJ）的 CBCT 图像进行分析，以确定 PRGF 和 PAT。由于创伤、退行性变、TMJ 先前手术等原因，28 例患者被排除在外。在 350 例患者中有 297 例发现了气化，但有 53 例未发现气化。记录了年龄、性别、偏侧性（单侧、双侧）和腔隙性（单腔隙、多腔隙）。单侧类型也记录为右和左定位。卡方检验用于评估气化与性别、腔隙性和偏侧性之间的关系。
在 491 个（70%）TMJ 中诊断出 PRGF 和/或 PAT，其中 178 个（51%）为男性，172 个（49%）为女性，平均年龄为 40.38±18.34 岁。总共有 103 例（35%）患者为单侧气化，194 例（65%）患者为双侧气化。
与 2D 图像相比，CBCT 提供了可靠、精确的图像来检测 TMJ 周围结构的气化。在进行手术干预之前，准确评估 TMJ 组件对于预防并发症或提高治疗成功率至关重要。
