Congénitale Malformations of the Nose

Nasal development is the result of a complex embryologic patterning and fusion of multiple primordial structures. Loss of signaling proteins or failure of migration or proliferation can result in structural anomalies with significant cosmetic and functional consequences. The nasal malformation on these clinical images is exceptional. In our knowledge it has never been described in the literature. It is secondary to the non-fusion of the upper edge of the creater alar cartilage to the lower edge of the lateral cartilage (Figures 1-4).

The surgery consists of dissection of the lower edge of the lateral cartilage and the upper edge of the creater alar and ensure the recapture of both cartilage: suture of the nasal mucosa, a noued between the two cartilages, finally suture of the skin.
