Investigation of temporomandibular dysfunction in patients with breast cancer-related lymphedema

This study aims to investigate temporomandibular joint dysfunction (TMD) in patients with breast cancer-related lymphedema (BCRL) and to determine the relationship between TMD severity and posture, range of motion (ROM), psychological status, and lymphedema (LE).

Sociodemographic characteristics and previous treatments of 38 individuals included in the study were recorded. The Craniomandibular Dysfunction Index for Clinical (CMDIC) and visual analog scale (VAS) evaluated TMD symptoms, signs, and pain. Patients were divided into three groups: mild, moderate, and advanced TMD, according to CMDIC results. LE stages of the patients were recorded. The severity of LE, range of motion (ROM), anxiety and depression, and posture analysis were evaluated with circumference measurement, goniometer, Turkish version of the Hospital Anxiety and Depression Scale (HAD), photogrammetric assessment method, and inclinometer, respectively.

Different degrees of TMD were detected in all patients. There was a significant difference between the groups regarding post-op period duration, work status, posture, and ROM (p < 0.05). The groups' LE stage, LE severity, and scores of HAD and VAS were similar (p > 0.05).

According to the results of this study, TMD is highly prevalent in BCRL patients. It is necessary to monitor TMD and its impact on the range of motion and posture. The post-op period duration can determine the development of TMD in this patient group.
