Introduction: There is high prevalence of TMJ functional impairment; these are the product of several factors that lead to joint overload and occlusal nonstability, with triggers and accelerator factors that reach irreversibly degenerated joint; being required functional surgery.
Purpose: Assess the use of disc repositioning surgery with absorbable anchors, symptoms after surgery, success rate, and life quality, and to continue Prospective Phase II in 2011 and ratify the protocol of surgical management and the postoperative care for structural internal derangement of TMJ.
Patients and methods: A retrospective study of 37 patients (70 joints) of the Hospital Universitario de la Samaritana, in 5 years of observation. Patients were classified by degree of severity of the alteration, within the Wilkes stages, furthermore the use of success criteria mandibular function given by the ASTMJS and AAOMS. With a postoperative evaluation to one week, 15 days, one month and six months; assessed with diagnostic imaging and clinical results standardized to take the positive data and the results of the procedure.
Results: Most patients showed improvement in pain, function, life quality, lack of noises; the postoperative MRI showed the properly disc positioning. With lows presence of complications inherent to the manipulation of flaps as neuropraxy.
Conclusions: Discopexy with absorbable mini anchor for advanced dysfunction TMJ disc is adequate in terms of clinical improvement, function and morphology. And the successful treatment of internal derangement of the TMJ should be based on proper diagnosis, careful surgical technique and diligent postoperative care.
