The aim of this study was to evaluate the association of persistent facial pain with tissue injury among subjects in the National TMJ Implant Registry and Repository. This case-control analysis included three groups: No surgery and no implant, TMJ surgery only and TMJ implant surgery. Unconditional binary logistic analyses were used to assess the association of tissue injury (by implant or surgery), comorbid conditions, and gender with persistent facial pain. Persistent pain was reported by the majority (64%) of the 645 subjects, and there was no difference among age groups. Number of surgeries was related to persistent pain, irrespective of whether the surgery involved an implant. When adjusted for number of TMJ surgeries, TMJ surgery without implant was associated with persistent pain while implant surgery had a weak and insignificant association with persistent pain. Among the comorbidities studied, headache, low back pain, and fibromyalgia were most frequently reported, followed by chronic fatigue syndrome and rheumatoid arthritis. The increased odds of persistent pain remained when the model was adjusted for depression, anxiety, and number of comorbid conditions. These data indicate the number of surgical procedures a patient underwent was related to persistent facial pain irrespective of type of surgery or comorbidities.
