Title: Fibrous Adhesions in the Joint Compartment of the Temporomandibular Joint Associated with Experimental Opposite Drawing Mandibular Ramus in Rabbit
Abstract: AbstractThe purpose of this study was to develop a rabbit model of fibrous adhesions in the joint compartment of the temporomandibular joint (TMJ) without surgical invasion into the joint compartment. A unilaterally elastic force of about 120 grams was applied from the anterior edge of masseteric tuberosity to the posterior part of the zygomatic arch between the masseteric fascia layer and the subcutaneous layer in 14 rabbits. The blocks of nondrawing side TMJ were removed after four weeks. Fibrous adhesions were observed in 13 rabbits except for one rabbit that lost over 30% of its body weight. In eight of the rabbits, the adhesions were detected in both joint compartments. This animal model for fibrous adhesion of the TMJ will be useful in understanding the pathogenesis of adhesion in human TMJs.
