Congenital Nasal Cartilage Deformities

Abstract

A unique case of congenital nasal septal deformity is reported with a chronological summary of literature pertaining to congenital nasal defects.

Dome Reconstruction in a Rare Case of Alar Cartilage Agenesis of the Middle and Lateral Crura

“…To our knowledge, the literature only contains a few cases that document nonsyndromic congenital absence of cartilaginous components of the lower lateral crura [4,6,8,11].…”

“…During embryonal growth the primitive face develops from five facial prominences, of which the superomedially placed nasofrontal process is responsible for the development of the nose during the third to tenth week [4]. Mesenchymal proliferation leads to the formation of medial and lateral nasal prominences, which then fuse to form the nostrils.…”

“…Reconstruction was based on costal cartilage [4]. Kosin et al reconstructed a unilateral total segmental loss of the entire middle crus with a columellar strut, an interposition graft and a concealer graft [6].…”

Congenital Isolated Aplasia of Lower Lateral Cartilage and Reconstruction Using Dorsal Hump Material

“…4 Only 3 cases of LLC defects have been reported. 2,11,12 Craniofacial clefts, including nasal defects, were defined and classified by Tessier. 13 This classification did not refer to the isolated congenital anomalies of the nose.…”

“…1 There are various reports describing non-syndromic aplasias of nasal cartilaginous structures in the literature. 1,2 We found 3 reported cases of isolated non-syndromic lower lateral cartilage (LLC) aplasia. 3 Alar cartilage defects cause nasal tip deformities, and septal or conchal cartilages are usually used for reconstruction.…”
