Nasal prominence

Nasal prominence is a significant anatomical feature that forms during the embryonic development of the human face. It is a central structure that contributes to the formation of the nose and the upper lip.

Development

The nasal prominence develops from the frontonasal process, which is one of the five facial prominences that appear in the fourth week of embryogenesis. The frontonasal process gives rise to two lateral nasal prominences and one medial nasal prominence. The medial nasal prominences merge to form the nasal prominence, which eventually forms the bridge and septum of the nose, and the philtrum of the upper lip.

Morphology

The nasal prominence is initially a rounded structure located in the center of the embryonic face. As development progresses, it elongates and narrows, eventually taking on the shape of the mature nose. The size and shape of the nasal prominence can vary greatly among individuals, contributing to the wide range of human nose shapes.

Clinical significance

Abnormal development of the nasal prominence can lead to a variety of congenital anomalies, including cleft lip and cleft palate, nasal septum deviation, and various forms of nasal deformity. These conditions can have significant impacts on an individual's appearance, breathing function, and quality of life.
