Abstract:
Nasal dermoid cysts are a common congenital midline nasal lesion. Surgical removal may require cranial exposure, a nasal approach, or a combination of the two, and is dictated by the location and extent of disease. Here, we review common presentations of nasal dermoids and illustrate extirpation by each of these three potential approaches. In this series, a 4 year-old female, a 6 year-old female, and a 3 year-old male underwent a transcranial, open rhinoplasty, and combined transcranial and open nasal approach, respectively, without complications. This series reviews the presentation and surgical treatment of nasal dermoids with transcranial extension and illustrates 3 commonly employed approaches for the removal of nasal dermoids.

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,...
