temporomandibular joint ankylosis causes limitation in mouth opening and establishes severe deformity and asymmetry in patient’s face, especially in children. surgery is the only treatment. this study was conducted to compare the effect of two surgical approaches, gap arthropasty and interpositional gap arthroplasty, on rate of maximum interincisal opening in temporomandibular joint ankylosis. ...

OBJECTIVE Temporomandibular joint (TMJ) ankylosis results from trauma, infection and inadequate surgical treatment of the condylary area. Many techniques for treatment have been described so far. However, none of them gave uniformly successful results. A limited range of intrinsical opening due to relapse, loss of vertical height of the affected ramus, foreign body reactions and reankylosis are...

Successful management of temporomandibular joint (TMJ) ankylosis depends on adequate gap arthroplasty and interpositional graft; the objective is to produce a functioning pseudoarthrosis that prevents reankylosis and provides adequate mobility. Several interpositional grafts have been used for the treatment of temporomandibular joint ankylosis such as indigenous pterygomasseteric sling, tempora...

BACKGROUND This study has been conducted with the aim of evaluating modified T-plate interpositional arthroplasty. METHODS A prospective comparative study in patients admitted with temporomandibular joint ankylosis. Ankylotic temporomandibular joint arthroplasty included condylectomy gap arthroplasty in 7, temporalis muscle flap interpositional arthroplasty in 8, and modified T-plate interpos...

The objectives of the study were to evaluate the outcome of Gap arthroplasty and Interpositional arthroplasty in terms of mouth opening for management of TMJ ankylosis. This Quasi experimental study was carried out in Oral & Maxillofacial Surgical unit, Khyber College of Dentistry, Peshawar from May 2006 to August 2007. Sixty patients of TMJ ankylosis seeking treatment for the first time, irres...

background: different interpositional materials have been used to prevent recurrence after gap arthroplasty in temporomandibular joint ankylosis. in this study, the temporalis superficial fascia flap was evaluated as an interpositional material after condylectomy.   materials and methods: 9 cases of unilateral or bilateral temporomandibular joint ankylosis were evaluated in this study with a fo...

We have reviewed the clinical and experimental reports regarding interpositional arthroplasty materials in the treatment of temporomandibular joint(TMJ) ankylosis. The aim of this review is to determine what constitutes an ideal interpositional material and whether any of the existing materials reported in the literature provide all requirements of an effective disc substitute following the sur...

Surgical intervention by resection of the ankylotic mass through gap arthroplasty alone resulted in reankylosis. Attempts have been made to prevent such reankylosis with interpositional arthroplasty. Numerous materials have been interposed between the resected bone surface and articular fossa at the base of the skull. Alloplastic materials such as silicone, silastic, proplast, Teflon, rubber pr...
