Abstract: Temporomandibular joint (TMJ) ankylosis commonly seen in Indian population as a result of trauma, causes problems in speech, mastication and sleep-disordered breathing.When left untreated for a long period, TMJ ankylosis can precipitate several structural sequelae such as restricted mandibular growth resulting in retrognathic and deviated mandible, decrease in facial height, malaligned dentition and poor jaw neck definition resulting into a great psychological stress. All these factors combined can have an extreme negative impact on the psychosocial development of the patient and hence should be treated early during the life time. Treatment designed for patients suffering from TMJ ankylosis and micrognathia is 1. Restoration of anatomic form and function 2. Promotion of physiologic growth in the affected region 3. Prevention ofreadhesion. 4. Correction of occlusal and facial deformities Protocol of Kaban has almost established theprocedures required for functional restoration in TMJ ankylosis. However there is still a long debate whether functional restoration should be carried out first or jaw to be lengthened first by distraction osteogenesis followed by functional restoration. This talk will highlight issues related to functional restoration of TMJ ankylosisand Distraction osteogenesis for aesthetic restoration of secondary dentofacial deformity. Novice technique of Dual distraction for simultaneous functional and aesthetic restoration, its indications and limitations will also be described.
