BACKGROUND AND OBJECTIVES:The number of temporomandibular joint (TMJ) surgeries has been growing in recent years. The objective of this study was to evaluate the factors measured for the indication of TMJ surgery. METHODS: This is an observational, quantitative, retrospective, cross-sectional study. A total of 99 surgical requests for TMJ surgery, assigned to a supplementary health operator, were analyzed. Information regarding age, gender, the patients' main complaint, movement alteration, magnetic resonance results, diagnostic tests used, and previous therapy performed were collected. The T-test and the Chi-squared test were used (α=5%). RESULTS: 85% of patients were female, and the mean age among women (27.07±6.33) was lower when compared to men (31.98±9.55) (p=0.03). Almost half of patients did not receive any therapeutic approach prior to the surgery indication. Less than 10% of the requests described the Wilkes classification. Among the symptoms considered for the indication of surgery. pain report in the TMJ region (63.64%) stands out. The clicking and mouth opening limitation were among the highest prevalence as 52.5% and 67.7%. respectively.
