Abstract:
Two patients presented with a transverse groove located between the lower third and upper two-thirds of the nose since birth. The alar and triangular cartilage attach themselves in a linear transverse fashion, the so called nasal line. It is important to recognize the nasal line as a localizing factor for milia, cysts and comedones. The nasal line is rather easily overlooked but awareness of its existence allows one to quickly confirm that it is not a rarity. We propose an embryological origin.

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...
