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

UNLABELLED: Congenital deformities of the nasal cartilage are extremely rare. Often, they remain undiscovered until an open approach is completed during rhinoplasty. We present a case of unilateral congenital agenesis of the middle and lateral crura of the alar cartilage. A new concept for dome reconstruction using conchal cartilage is introduced. Additionally, current concepts of embryology are summarized, which will help understanding the pathophysiology of such rare deformities.
