inverted V deformity
Definition: abnormal nasal contour named for the linear shadow that crosses the nasal sidewalls and bridge at the caudal end of the bony nasal vault and signifies medial collapse of the upper lateral cartilages toward the septum. Usually appears after rhinoplasty in which the cartilaginous dorsum has been resected, which destabilizes the upper lateral cartilages and produces this deformity externally and consequent narrowing at the internal nasal valves internally, decreasing airflow.
