Fig. 1. (A) Illustration depicting the exposed quadrangular cartilage donor site after nasoseptal flap harvest with outline of inferior meatus mucosal flap incisions and counterclockwise rotation. (B) Inferior mucosal flap rotated into position, covering the quadrangular cartilage. Note that the flap covers the superior area next to the nasal dorsum, which is a critical area that can lead to cicatricial contraction and saddle nose if left uncovered..
