This study evaluated pain scores and maximal incisal opening (MIO) in patients with total alloplastic temporomandibular joints found to have post-surgical neuromas following revision arthroplasty, compared with patients who underwent revision arthroplasty without neuromas. 19 cases were reviewed of which 11 had neuromas excised. Data were available for 8 cases in the immediate postoperative period and 7 cases had follow-up data. 8 patients had revision arthroplasty with excision of scar tissue (7 with postoperative, 4 with long-term data). Follow-up ranged from 2 months to 5.9 years (mean 1.2 years). 6 of 8 patients obtained clinically significant pain reduction in the immediate postoperative period when their neuromas were excised, compared with 3 of 7 patients without neuromas. On long-term follow-up, 3 of 7 patients in the neuroma group had clinically significant pain reduction, 3 reported lower pain scores, 1 had no pain change. No patients had increased pain. 1 of 4 patients in the scar revision group had clinically significant pain reduction, 2 had no change, 1 reported increased pain. Mean MIO was 23 mm preoperative and 28 mm postoperative in patients with neuromas, compared with 27.75 mm and 31.25 mm, respectively, in patients without neuromas.
