Abstract:
Temporomandibular joint (TMJ) ankylosis in children is one of the most complex and challenging problems managed by oral and maxillofacial surgeons. TMJ ankylosis in growing children often leads to facial deformity, difficulty in chewing and swallowing, severe malocclusion, poor oral hygiene, multiple decayed teeth, and impairment of speech. A good functional and esthetic outcome can be achieved after reconstruction with the autogenous grafts. Here, we present a case of a 9-year-old patient treated with condylectomy and ipsilateral coronoidectomy, followed by reconstruction with costochondral graft with 5 years of follow-up. During this period, the reconstructed graft remodeled into a neocondyle and also regrowth of the coronoid process. The mouth opening and facial symmetry were acceptable.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
