Manejo cirúrgico de disfunção temporomandibular pós cirurgia ortognática bimaxilar: Relato de caso clínico

Abstract

Orthognathic surgery is one of the main resources used to correct dentofacial deformities, helping to achieve a functional balance between the maxillary bone bases. However, the impact of this surgery on the temporomandibular joint (TMJ) and on symptoms related to temporomandibular dysfunction (TMD) is still debated in the literature, especially in patients who already have joint alterations before the procedure. This paper presents a case of a young patient who, after undergoing bimaxillary orthognathic surgery, presented with intense bilateral pain in the temporomandibular joint; and after clinical evaluation based on the DC/TMD criteria and analysis by imaging exams (CT scan and MRI), bilateral disc displacement without reduction, trismus with limitation of opening, laterality, and protrusion movements were found. The patient underwent bilateral discoplexy, showing significant improvement in pain symptoms and satisfactory functional recovery.
