Gap arthroplasty at least 1cm to prevent reankylosis (6) was advocated by Abbe in 1880, and refined by Risdon in 1934.
Comparison of Gap Arthroplasty With and Without a Temporalis Muscle Flap for the Treatment of Ankylosis.
Treatment comprised gap arthroplasty, removal of the deformed meniscus and condylar fragment, and replacement of interpositional material with alloplastic material of Silastic.
sup] Gap arthroplasty and interpositional arthroplasty under general nasotracheal anesthesia was subsequently recommended.
was the foremost technique used and some surgeons still advocate it to be the treatment of choice as they have achieved good results with it.
5) recommended a gap of at least 15 mm between the recountoured glenoid fossa and the mandible and subjected this gap to extensive active jaw opening exercises to prevent re-ankylosis when using gap arthroplasty
Temporalis fascia was interposed between the articular surfaces in this case for its proven advantage over gap arthroplasty
in avoiding recurrence5.
Moorthy and Finch1 broadly classified the usual treatment of ankylosis of the tem- poromandibular joint in three groups: a) Condylectomy b) Gap arthroplasty
c) Interpositional arthroplasty.

Treatment of temporomandibular joint ankylosis by gap arthroplasty
Interpositional Gap Arthroplasty
was found highly effective and safe surgical management option for temporomandibular joint with acceptable immediate and long term outcome, particularly when temporalis fascia or muscle and iliac crest grafts were used for adults and costochondral grafts with fascia interposition used for children.
Thirty patients were treated by gap arthroplasty
(group A), while thirty patients by disc interpositional arthroplasty (group B).
