Patient-centered quality of life measures after alloplastic temporomandibular joint replacement surgery

The purpose of this study was to evaluate patient-reported outcome measures of quality of life (QoL) for patients with end-stage temporomandibular joint (TMJ) disease who have undergone TMJ prosthetic replacement. The records of 36 patients who had undergone alloplastic total joint replacement procedures were analyzed. Patients were treated using either TMJ Concepts or Biomet/Lorenz prosthetics. Patients were asked to complete a 12-item TMJ-S-QoL survey, which encompassed questions pertaining to pain, speech, chewing function, and various aspects of social life and mental health. The questions were answered on a 5-point scale. Data were analyzed using the Wilcoxon signed-rank test. Among the 36 patients (six male and 30 female), 18 responded to the survey. Markers of QoL after surgery were compared to the preoperative period. Significant improvements were reported for pain (94.4% of patients), chewing (83.3% of patients), speech (55.6% of patients), anxiety (72.2% of patients), activity (66.7% of patients), recreation (61.1% of patients), and mood (66.7% of patients) (all P<0.05). TMJ prosthetic replacement significantly enhanced QoL among patients suffering from chronic pain, limited range of motion, anxiety, impaired speech, and chewing due to end-stage TMJ disease in this sample of surgical patients.
