Rotation of the alar cartilage in collapsed ala.
There are various causes for collapsed ala nasi. In elder people especially, the lateral crus of the alar cartilage is frequently deformed in shape and position. Model experiments show that by rotation of the lateral crus outwards and upwards, the vestibulum is expanded and the tip of the nose raised. On the basis of these experiments, in 19 patients with collapsed ala nasi, the lateral crus of the alar cartilage was rotated dorsally. The longterm results showed a satisfactory functional and aesthetic outcome.
