Abstract:
Malposition of the lateral crus is a normal variant of the nasal alar cartilage as described by Sheen which shows a "parentheses" deformity from the frontal view. The cephalic-positioned lateral crus leaves the alar rims without cartilaginous support, causing deformity and potential destabilization of normal airway competence. The procedure described herein is a modification of the Sheen technique that can be done as either an open or a closed procedure. It is particularly valuable in decreasing the overprojecting nasal tip and preserving the equal height of the alar domes while widening the angle of divergence of the lateral crus. This technique delivers consistently dependable results for an anatomic variant modification frequently overlooked in rhinoplasty surgery.

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...
