Abstract (original English)

To measure and identify factors associated with treatment outcomes for patients with temporomandibular joint (TMJ) ankylosis treated with TMJ Concepts patient-fitted total joint prostheses and autogenous fat grafts. This retrospective cohort study evaluated records of patients with TMJ ankylosis from a single private practice, treated from 1992 to 2011, who met the following inclusion criteria: 1) radiographic evidence of bony ankylosis, 2) limited incisal opening, 3) minimum of 12 months' follow-up, and 4) treatment with TMJ Concepts (Ventura, CA)/Techmedica (Camarillo, CA) total joint prostheses and fat grafts. For each patient, the number of previous TMJ surgical procedures, as well as the estimated age of ankylosis onset, age at surgery, and length of postoperative follow-up, was recorded. Subjective evaluations were made with Likert-like scales (from 0 to 10) for 1) TMJ pain, 2) headache and facial pain, 3) jaw function, 4) diet, and 5) disability. Objective evaluations included maximal incisal opening and excursion movements. Nonparametric statistics were used for analysis. There were 32 patients (22 female and 10 male patients) with 48 ankylosed TMJs (16 bilateral and 16 unilateral) in this study, with a mean age of 39 years (range, 11 to 68 years), 2 or more previous TMJ surgical procedures in 69%, and a mean follow-up period of 68 months (range, 12 to 168 months).
