[Intraoral transpositional plastic surgery of coronoid process in treatment of recurrent TMJ luxation. Preliminary report].

As a preliminary communication, we introduce a surgical procedure not previously described--intraorally performed ventrocaudal transpositional plastic surgery of the coronoid process for the treatment of recurrent TMJ luxation. The aim is to provoke an early stretch reflex of the temporal muscle and tendons by surgically shifting its insertion when the mouth is opened to an extreme position. Physiologically, this limits the extent to which the mouth can be opened and counteracts luxation. We report on initial clinical results of the intraoral transposition of the coronoid process after on observational period of 9 months.
