Abstract:
Proboscis Lateralis is a rare congenital anomaly composed of an accessory tubular appendage with possible associated craniofacial anomalies. Computed tomography scan is essential for evaluation of the anomaly and proposing a plan of management. Treatment is complex and should be individualized. The authors present the case of an 18-month old female with left proboscis lateralis associated with left heminasal hypoplasia and coloboma of the left upper eyelid.

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,...
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...
