Fibromyalgia is not a predictor variable for a successful outcome following surgical correction of internal derangement of the temporomandibular joint.
OBJECTIVE
The purpose of this study was to compare surgical outcomes of subjects with and without fibromyalgia using a logistic regression model.


METHODS
This study was a retrospective chart review of 28 subjects who underwent surgery to correct internal derangement of the temporomandibular joint. Subjects were classified as having a successful or an unsuccessful outcome based on a verbal rating scale, diet restrictions, and maximum mouth opening (MMO). Data were recorded from 3 different assessments (preoperative, 6 weeks after surgery, and 3 to 5 months after surgery).


RESULTS
No significant difference was noted in outcomes between subjects with and without fibromyalgia (P = .61). The 4 significant predictor variables for surgical success were MMO before surgery, MMO and verbal rating scale scores at 6-week examination, and type of surgery.


CONCLUSIONS
A comorbidity of fibromyalgia was not a predictor for successful outcomes. Predictors of successful outcomes included subjects with a large MMO (≥38 mm) and a low verbal rating scale score (≤2) at 6 weeks.
