Para-alar crescentic subcutaneous pedicle flap for severe stenosis of anterior nares.

Atresia and stenosis of the anterior nares caused by scar contracture is one of the intractable conditions that may arise after facial injury. Using the standard surgical methods, such as mucous membrane and/or skin graft and intranasal local flap, the new nostril has a tendency to restenose. Para-alar crescentic subcutaneous pedicle flap, which was intended to cover the skin defects in and around the philtrum, was applied to treat severe stenosis of the nostril caused by scar contracture. The procedure resulted in improvement of nasal obstruction with satisfactory postoperative appearance of the external nose. This article presents an operative technique using this flap for severe stenosis of anterior nares.
