OBJECTIVE Temporomandibular joint (TMJ) ankylosis, not only results in joint hypomobility, but also causes considerable facial deformity. Its unilateral variant can cause facial asymmetry, leading to major psychosocial effects on the individual. METHODS We present the cases of 7 patients with unilateral TMJ ankylosis and facial asymmetry of various grades who have been treated using gap arthroplasty and simultaneous dual distraction. Considerable debate has surrounded the sequencing of TMJ release and distraction osteogenesis; however, the simultaneous approach has recently become popular. The use of a single distractor simultaneously with TMJ release has been widely reported. However, one disadvantage with this technique is that the proximal condylar segment remains unstable. Dual distraction is a newer technique which we have proposed as a single-stage approach for the correction of TMJ ankylosis and facial asymmetry and to address the problems resulting from the use of a single distractor. RESULTS After treatment, all the patients showed a mouth opening ranging from 35 to 50 mm and satisfactory facial symmetry. CONCLUSIONS Dual distraction is a promising technique in the correction of facial asymmetry. However, further studies with adequate statistical analysis and larger sample size are required.
