| Popis: | Temporomandibular joint ankylosis is a major disorder, mainly due to trauma and other reasons, which is responsible for the restriction of mandibular functional activities. The scope of the successful surgical correction of temporomandibular joint ankylosis with amniotic membrane is on the membrane's being an interpositional material which we found not to elicit any host reaction, is capable of functional adaptation, and is very economical. Our purpose is to show the amniotic membrane as a suitable, biocompatible, and interpositional material alternative to the other materials, thereby reducing donor site morbidity.A study was conducted in 13 patients with an age range of 10 to 35 years with unilateral and bilateral bony TMJ ankylosis confirmed by clinical and radiological evaluations. Preoperative and postoperative clinical assessments of TMJ functions were done. Amniotic membranes were collected from the tissue bank, sterilized by gamma radiation, and freeze-dried. Then, the prepared amniotic cap (10-15 layers of amniotic membrane) was placed over the condylar head and anchored loosely to the neck and the surrounding tissues with a 3/0 Vicryl suture.Measurements of postoperative maximum interincisal opening was taken with scale among the 13 patients. Preoperative interincisal distances ranged from 0 to 15 mm, and preoperative and immediate postoperative were 33-45 and 25-32 mm, respectively. Postoperative follow-up of interincisal opening after 1-, 6-, and 12-month intervals was found from 32 to 35 mm. Lateral excursions (left and right), protrusive movements, and functional recovery were all satisfactory.Amniotic membrane graft as an interpositional material in temporomandibular joint ankylosis can be a good alternative as to prevent reankylosis and recover functionality. |
