Postsurgical Alar Retraction Etiology and Treatment

摘要

The cephalic trim technique is a popular maneuver that often leads to tip deformities, most notably postsurgical alar retraction (PSAR). We advocate using the external rhinoplasty approach to correct PSAR by (1) releasing and repositioning the retracted alar margin, (2) strengthening and immobilizing the central tip complex using a septal extension graft, (3) suspending and longitudinally tightening the mobilized lateral crural remnant by adjusting crural length to match the sidewall span, and (4) providing direct skeletal support to the repositioned alar margin using articulated alar rim grafts. Using this structural treatment paradigm, we have corrected severe PSAR in the preponderance of secondary rhinoplasty cases.
