ABSTRACT
Anterior disc displacement without reduction of the temporomandibular joint is a prevalent condition associated with pain and functional limitation, and minimally invasive arthroscopic approaches are increasingly favored over open surgery due to lower morbidity. This study compared three arthroscopic interventions: classical myotomy (CM), minimally invasive anterior arthroscopic myotomy (MIAAM), and posterior ligament electrocoagulation (PLE). A total of 86 patients were included: 24 (27.9%) underwent CM, 30 (34.8%) underwent MIAAM, and 32 (37.2%) underwent PLE. Outcomes were assessed using visual analog scale (VAS) pain, maximum mouth opening (MMO), and joint function at baseline and at 1 and 6 months postoperatively. Pain improved significantly over time in all groups (F = 5.02; df = 2; p < 0.05), with no significant differences between techniques. Maximum interincisal opening (MIO) and mandibular protrusion also improved significantly (F = 14.6; df = 2; p < 0.05 and F = 8.949; df = 2; p < 0.05, respectively), again without inter-group differences. MIAAM was associated with faster pain relief at 1 month and slightly better 12-month outcomes, although these differences were not statistically significant. Overall, PLE showed comparatively less favorable results, suggesting MIAAM may represent a balanced option in terms of efficacy and safety.
