Long-Term Functional Outcomes of TMJ After Maxillofacial Trauma

Abstract

Background:Maxillofacial trauma involving the temporomandibular joint (TMJ) may lead  to long-term functional complications affecting mandibular movement, mastication, speech,  and overall quality of life. Condylar fractures and associated TMJ injuries are commonly  associated with pain, restricted mouth opening, malocclusion, and joint dysfunction. Aim:To evaluate the long-term functional outcomes of the temporomandibular joint  following maxillofacial trauma and to assess associated clinical complications affecting TMJ  function. Materials and Methods:The present retrospective cross-sectional study included 50 patients  with a previous history of maxillofacial trauma involving the TMJ region. Clinical evaluation  was performed to assess mouth opening, mandibular deviation, TMJ pain, joint sounds,  malocclusion, and mandibular movements. Radiographic assessment was performed using  panoramic radiographs and CT/CBCT imaging as required. Functional outcomes were  correlated with trauma aetiology and treatment modality. Results:The majority of patients were in the 21–40-year age group, with male predominance.  Road traffic accidents were identified as the most common cause of trauma. Restricted  mouth opening and TMJ pain were the most frequently observed long-term complications.  Joint sounds, mandibular deviation, and malocclusion were also observed in several patients.  Surgically managed patients demonstrated comparatively better functional outcomes than  conservatively treated cases. Conclusion:Maxillofacial trauma involving the temporomandibular joint may result in  persistent long-term functional impairment despite treatment. Early diagnosis, proper  treatment planning, rehabilitation, and long-term follow-up are essential for restoring  optimal TMJ function and minimising post-traumatic complications. Advancement of Knowledge The present study provides a comprehensive evaluation of long term temporomandibular joint dysfunction following maxillofacial trauma and highlights  the importance of functional assessment during long-term follow-up. The study emphasises  the association between condylar trauma and persistent complications such as restricted  mouth opening, TMJ pain, and mandibular deviation. It further demonstrates that surgically  managed cases show improved functional recovery compared with conservative treatment.  The findings contribute to a better understanding of post-traumatic TMJ complications and  support the importance of early intervention, radiographic evaluation, and rehabilitation in  improving patient outcomes.
