Preoperative and postoperative assessment of external nasal valve in rhinoplasty

Rhinogoniometer: Validation of an Instrument for Rhinoplasty

“…he position of the lower lateral cartilage is directly related to proper functioning of the nose, 1 as it is the main structural element of the external nasal valve. 2,3 When this cartilage exhibits cephalic malposition, there is a significant impact on the contour and stability of the nasal tip and ala and, consequently, on the external nasal valve, possibly resulting in alar collapse during deep inspiration and airflow obstruction. [4][5][6][7][8] Thus, during rhinoplasty, it is essential to assess the angle of divergence of the lower lateral cartilage that is formed between the lateral branches of this cartilage.…”

A New Graft Technique For Rhinoplasty: Modified One-Piece Nasal Cap With Alar Strut Graft

“…Studies with pre- and postoperative rhinomanometry concluded that proper breathing is not only related to the absence of septal deviation, but also the proper functioning of the nasal valves 5 . The position of the lower lateral cartilages plays an important role in the proper functioning of this valve, because these cartilages are the main structural elements of the lateral wall, 6–8 weakness of these cartilages lead to dysfunction of external nasal valves (ENVD), because ENV obstructs normal breathing 9 . This obstruction leads to symptoms of reduced airflow, such as alar collapse, pressure and fullness in the nose 10 .…”
