[Arthrotomy for the permanent displacement of the temporomandibular meniscus. A coagulation-retraction technic of the posterior meniscal frenum]. / Arthrotomie pour déplacement permanent du ménisque temporo-mandibulaire. Technique de la coagulation-rétraction du frein méniscal postérieur.

An original technique for surgical treatment by arthrotomy for permanent closed lock of the temporo-mandibular joint is described. This technique uses the temporo-meniscal compartment approach. The superior belly of the posterior meniscal attachment is dissected and retracted by a diathermy coagulation. Advantages of this technique are compared to the usual techniques of meniscopexy and meniscorrhaphy using a suture. The indications are proposed.
