Abstract
Objectives: The objective of this study is to evaluate the facial profile after mandibular advancement with distraction osteogenesis using an extra-oral device in patients with temporomandibular joint (TMJ) ankylosis. Soft tissue response to the mandibular advancement and stability were also evaluated over a period of 6 months. Study: Six patients—five patients with bilateral and one patient with unilateral TMJ ankylosis were considered. These patients underwent surgical correction of TMJ ankylosis and mandibular hypoplasia using distraction osteogenesis with extra-oral device. Results: There was an effective horizontal advancement of mandible that was clinically significant as noted by increase in the Go-Pog length (average increase by 13 mm) and angle of Ar-Go-Pog (average increase by 16o). In all patients the mouth opening was well maintained with an average of 22 mm. The 6 months post distraction evaluation indicated a minimal degree of relapse of both the hard tissue and soft tissue profiles which were clinically insignificant. Conclusion: Distraction osteogenesis for TMJ ankylosis serves dual purposes of achieving mouth opening and of lengthening of the hypoplastic mandible. This avoids a second procedure, its risks and complications. This is a viable alternative to conventional procedures in the management of TMJ ankylosis.
