Importância da ultrassonografia no diagnóstico diferencial de reações adversas ao polimetilmetacrilato em estética facial: relato de caso clínico

Abstract

INTRODUCTION: The use of ultrasonography in Dentistry has expanded due to its ability to assess oral and facial structures in real time, enabling the identification of filler materials, vascular mapping, and soft tissue analysis without exposure to ionizing radiation. In orofacial harmonization, its application contributes to greater diagnostic safety and risk reduction, especially in the context of complications associated with permanent substances such as polymethylmethacrylate (PMMA). OBJECTIVES: To demonstrate the importance of ultrasonography in the evaluation of a clinical case with suspected adverse reaction to PMMA, highlighting its usefulness in differential diagnosis and in guiding therapeutic decisions. METHODOLOGY: The case of a patient referred to the School Clinic of the Goyazes University Center - Trindade/GO, with a history of facial filling of unknown origin and reports of symptoms consistent with a late complication, was analyzed. The ultrasound examination allowed the identification of changes suggestive of the presence of PMMA and provided essential information for the therapeutic plan. CONCLUSION: It is concluded that ultrasonography is an effective, accessible, and safe tool for clinical practice in orofacial harmonization, contributing to prevention, early diagnosis, and appropriate management of adverse reactions.
