Abstract:
Dorsal preservation rhinoplasty in cases of a convex or overprojected noses has significant advantages over resection and reconstruction of the dorsum. Analysis of the subdorsal septum in relation to the radix osteotomy to achieve a drop or hinge of the natural dorsum is important in avoiding possible complications involving the skull base, frontal sinus, and subsequent radix position. In the majority of patients, simple cut release of the perpendicular plate rather than resection superiorly may be necessary where the quadrangular cartilage junction with the perpendicular plate is caudal to the radix osteotomy. Computed tomography is helpful in delineating this position as well as providing information on the frontal sinus and position of the cribriform plate prerhinoplasty.

01:27Cranial 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...
01:14Cranial 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,...
01:22Sutures 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...

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...
