Background: TMJ ankylosis is an incapacitating disease of Temporomandibular joint causing restriction in jaw movements. Surgery remains the mainstay of the treatment. However the decrease in ramal height following arthrectomy remains an issue in comprehensive functional treatment. To achieve this, various reconstructive options, both autogenous as well as alloplastic have been tried with variable amount of success. The present comparative study presents the preliminary results of reconstruction of TMJ with those where no reconstruction was done. Material and Methods: 10 patients with TMJ ankylosis (unilateral or bilateral) were divided into 2 groups Group A in which reconstruction was done using Sternoclavicular graft or Costochondral graft following arthrectomy. Group B in which no reconstruction was done following arthrectomy Results: All patients were treated with arthrectomy and there was no recurrence noted in any case. The group A patients showed better functional results such as mouth opening and lateral excursion as well as gain in ramal height.
