title: Random control trial of dermis-fat graft and interposition of temporalis fascia in the management of temporomandibular ankylosis in children.
abstract: Temporomandibular ankylosis is a disabling condition that affects hygiene and cosmetic appearance. Several interpositional grafts such as meniscus, muscle, fascia, skin, cartilage, fat, dura, alloplastic materials and xenografts have been used to prevent recurrence of ankylosis. We studied the advantages and disadvantages of dermis fat graft as an interposition material after arthroplasty and compared it with temporalis fascia interposition. Seventeen patients with temporomandibular ankylosis involving 20 joints were randomly divided into two groups; the first group had operations for interposition of dermis-fat graft that was taken from the groin. Patients in control group had operations to interpose temporalis fascia and muscle from the same surgical site. All were assessed by age, sex, etiology, clinical features and post surgical complications. The groups were matched in age and the male: female ratio was 0.89:1.The median duration of ankylosis was 7.3 (range 2-11) years. Postoperative and follow up interincisal mouth opening was satisfactory with good healing of the dermis-fat graft donor site. We conclude that the use of dermis fat grafts has minimal donor site morbidity, and is a safe and effective interposition material to prevent the recurrence of temporomandibular ankylosis.
