Abstract

BACKGROUND Anterior reduction disc displacement (ARDD) of the temporomandibular joint (TMJ) can present with pain and clicking of the jaw when chewing. This study aimed to evaluate the relationship between articular eminence cortication (AEC) and mandibular condyle cortication (MCC) in 81 patients with ARDD of the TMJ using cone beam computed tomography (CBCT) imaging. MATERIAL AND METHODS We examined images of 142 patients who applied to the outpatient clinic between 2022 and 2024 for various reasons and whose radiographic records included CBCT and MRI images. Sixty-one patients who did not meet the inclusion criteria were excluded from the study. MRI images of the remaining 81 patients were analyzed and evaluated for the presence of ARDD. Subsequently, all mandibular condylar processes and articular eminences included in the study were examined by CBCT and the degree of cortication was classified and noted. The relationship between MCC and AEC and ARDD was evaluated with the SPSS 23.0 program (SPSS, Chicago, IL, USA). RESULTS ARDD was observed in 46 (28.4%) of 162 condyles examined. Type 1 cortications were observed in 8 (17.4%), type 2 in 36 (78.3%), and type 3 in 2 (4.3%) of the condyles with disc displacement; 80.0% (8) of type 2 cortications were found in patients with ARDD (P<0.001), and 75.0% of type 3 cortication was observed in intact condyles (P<0.001). CONCLUSIONS This study shows that loss of AEC and MCC may be a significant factor in the diagnosis of ARDD, and decreased AEC and MCC may be a criterion for the diagnosis of ARDD.

颞下颌关节前椎间盘移位和皮质化模式。
背景颞下颌关节(TMJ)的前缩盘移位(ARDD)可表现为咀嚼时下颌疼痛和咔嗒声。本研究旨在使用锥形束计算机断层扫描 (CBCT) 成像评估 81 例颞下颌关节 ARDD 患者的关节突皮质化 (AEC) 和下颌骨髁状突皮质化 (MCC) 之间的关系。材料与方法 我们检查了 2022 年至 2024 年期间因各种原因申请门诊的 142 名患者的图像,这些患者的放射记录包括 CBCT 和 MRI 图像。研究排除了 61 名不符合纳入标准的患者。对其余 81 名患者的核磁共振成像进行了分析和评估,以确定是否存在 ARDD。随后,研究中的所有下颌骨髁突和关节突均接受了 CBCT 检查,并对骨皮质化程度进行了分类和记录。使用 SPSS 23.0 程序(SPSS,芝加哥,伊利诺斯州,美国)评估了 MCC 和 AEC 与 ARDD 之间的关系。结果 在检查的 162 个髁突中,有 46 个(28.4%)观察到 ARDD。在有椎间盘移位的髁突中,有 8 个(17.4%)观察到 1 型骨质疏松,36 个(78.3%)观察到 2 型骨质疏松,2 个(4.3%)观察到 3 型骨质疏松;80.0%(8 个)的 2 型骨质疏松发生在 ARDD 患者中(P<0.05)。

期刊介绍: Medical Science Monitor (MSM) established in 1995 is an international, peer-reviewed scientific journal which publishes original articles in Clinical Medicine and related disciplines such as Epidemiology and Population Studies, Product Investigations, Development of Laboratory Techniques :: Diagnostics and Medical Technology which enable presentation of research or review works in overlapping areas of medicine and technology such us (but not limited to): medical diagnostics, medical imaging systems, computer simulation of health and disease processes, new medical devices, etc. Reviews and Special Reports - papers may be accepted on the basis that they provide a systematic, critical and up-to-date overview of literature pertaining to research or clinical topics. Meta-analyses are considered as reviews. A special attention will be paid to a teaching value of a review paper. Medical Science Monitor is internationally indexed in Thomson-Reuters Web of Science, Journals Citation Report (JCR), Science Citation Index Expanded (SCI), Index Medicus MEDLINE, PubMed, PMC, EMBASE/Excerpta Medica, Chemical Abstracts CAS and Index Copernicus.
