Second metatarsal free transfer in total temporomandibular joint reconstruction for ankylosis in a child: 10-year follow-up

Abstract : The management of temporomandibular joint (TMJ) ankylosis requires complete removal of the ankylosed block and the prevention of recurrence. For this purpose, the ramus?condyle unit can be reconstructed with a second metatarsal free flap. This article reports the use of this flap in a young patient treated for left TMJ ankylosis, post costochondral graft for the treatment of hemifacial microsomia. Data from the 10-year follow-up are reported. The glenoid fossa was reconstructed with a graft of the second metatarsal base, enabling the juxtaposition of two cartilaginous joint surfaces, with the aim of optimizing the functional result and preventing the recurrence of ankylosis. At the 10-year follow-up after this surgery, there was no recurrence of the ankylosis and no articular disorder, and the morphological result was satisfactory. Bone fixation was stable over the 10-year period and the metatarsal head was still in place. Quantitative measurements obtained by computed tomography scan did not show any growth of the second metatarsal free flap compared to the right unaffected condylar process.
