Artrocentese aplicada ao tratamento de disfunção temporomandibular: relato de caso

Abstract

INTRODUCTION: Arthrocentesis is a minimally invasive procedure performed in the temporomandibular joint (TMJ), with low risk of complications, high success rate and low operating cost. It is performed under intravenous, inhalational sedation or local anesthesia and consists of a surgical procedure in which a lavage of the supradiscal space is performed with the aim of breaking adhesions and eliminating inflammatory mediators to restore mandibular mobility and mouth opening. Arthrocentesis is considered the first line of treatment for patients with temporomandibular disorders who have not responded to conservative treatment. Among the indications for arthrocentesis are joint disc displacement with or without reduction, limitation of mouth opening of joint origin, joint pain and other internal derangements in the joint. OBJECTIVES: The objective of this study is to report the clinical case of a patient with TMJ pain, which was not resolved with the use of medications and a Michigan interocclusal device. METHODS: Patient B.N.S, 55 years old, complaining of pain in the temporomandibular joint region and limited mouth opening. FINAL CONSIDERATIONS: Arthrocentesis techniques are minimally invasive, do not leave scars and produce excellent results in the treatment of temporomandibular disorders, and may be a previous alternative to a more invasive surgical treatment. Arthrocentesis should be associated with treatment with interocclusal devices to achieve better results.
