Abstract:
A 52-year male patient reported with loosening of right upper jaw. He has no pain or discharge, or any acute symptoms and systemic disease. Intraoral examination reveals necrosed maxillary bone. He also has no sickle cell disease, hepatitis, HIV or tuberculosis. 3D CT scan reveals destruction of maxilla, maxillary sinus, lateral nasal wall, superior and inferior orbital wall, zygoma and frontal bone(outer table). The clinical diagnosis of osteomyelitis was made. Under general anaesthesia, sequestrectomy was done with the help of Weber-Ferguson incision with infraorbital extension for maxilla, maxillary sinus, zygomatic bone, lateral nasal wall and infraorbital and medial wall of orbit. Frontal sinus region sequestrectomy was done via bicoronal flap. The patient was completely diseased free after 4 years follow-up.

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...
Overview of the Skull
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...
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,...
Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
