Pediatric TMJ Ankylosis: Treatment Using Vertical Sliding Osteotomy of the Mandibular Ramus

Ramus Condyle Unit Reconstruction Using Vertical Ramus Osteotomy in Temporomandibular Joint Ankylosis

“…In this study, VRO, an extra oral technique has been used for condylar reconstruction using posterior border of ramus as pedicled graft in ten patients of osseous/fibro osseous ankylosis. Paula Cristina [2] described that through this technique, the reconstruction of the TMJ is performed using the block of osteotomized mandible itself without need of a new surgical approach to obtain the graft, significantly decreasing the morbidity of the surgical procedure and avoiding complications associated with the donor site.…”

“…Temporomandibular Joint (TMJ) Ankylosis is bony or fibrous adhesion of the anatomical joint components characterized by formation of an osseous, fibrous or fibroosseous mass fused to the base of the skull with ensuing loss of function and partial to almost complete inability to open the jaws and is primarily caused by trauma, infection or failed surgery [1,2]. When this occurs during development, it results in an alteration of the normal potential growth which leads to mandibular micrognathia, facial asymmetry and reduction of the normal functional spurs necessary for the development of the whole maxillofacial complex [2].…”
