Revisiting the Use of GORE-TEX as an Interpositional Material in Surgical Management of Severe Temporomandibular Joint Ankylosis.

(1) Defining a protocol for management of patients with severe temporomandibular joint ankylosis. (2) Review the results of use of GORE-TEX as an interpositional material in gap arthroplasty. All cases which were treated with surgical intervention for severe TMJ Ankylosis with use of GORE-TEX as an interpositional material have been included. Amongst 40 patients, 11 were male and 29 were female with age group ranging from 4 to 36 years. 22 patients had bilateral ankylosis and 18 patients had unilateral ankylosis needing unilateral condylectomy. In all the patients GORE-TEX was used as an inter-positional material to form a pseudo joint. Postoperative mouth opening was around 3 fingers (3-3.5 cm) for period of 2 years i.e. last follow up. Migration or extrusion of implant was not seen in any of our cases. Use of GORE-TEX as an inter-positional material can prevent recurrences with good restoration of the physiological joint and occlusion. © Association of Otolaryngologists of India 2020.
