Abstract

Reconstruction of the temporomandibular joint (TMJ) region is challenging. The conventional direct preauricular incision permits only limited access to the TMJ and surrounding structures, therefore risking injury to the facial nerve during retraction. The ideal approach allows sufficient exposure, preservation of underlying neurovascular structures, and achieves an optimal aesthetic outcome. We describe a preauricular posttragal incision with a superficial musculoaponeurotic system flap to allow wide exposure of the zygomatic arch, TMJ, condyle, and coronoid process. We postulate that this approach improves access, lessens the amount of retraction required, and creates a more inconspicuous scar.
