VI. DISCUSSION

Prior rhinoplasty was the number one cause of nasal valve collapse in this series. It is notable that one out of 68 primary septorhinoplasty patients required alar batten grafts, while 22 out of 44 revision rhinoplasty patients required alar batten grafts. Clearly, when history of prior rhinoplasty is elicited in a patient with nasal obstruction, the possibility of nasal valve collapse must be entertained.

FIGURE 3. This patient had a caudal septal deviation causing passive external nasal valve collapse and also had an excessively con-cave lateral crura contributing to nasal obstruction. In this case the caudal septum was straightened and the right lateral crus was excised and "flipped" to achieve both aesthetic improvement and improvement in the nasal valve area.
