Use of the Interalar Ligament Flap for Tip and Supratip Contouring in Primary Open Structural Rhinoplasty

Precise tip contouring is paramount to achieve pleasant cosmetic results in rhinoplasty. Loss of tip projection or rotation, supratip deformities, and long-lasting edema may jeopardize the outcome and lead to patient dissatisfaction or to reintervention. Several approaches have been reported, sometimes with considerable drawbacks or conclusions supported mainly by experience. The aim of this study was to describe the interalar ligament flap for tip and supratip contouring and to comparatively assess its efficacy and safety. The study included 147 patients who underwent primary structured open rhinoplasty and were divided into 2 groups: group 1 underwent harvesting and repositioning of the interalar ligament flap, and group 2 underwent conventional tip dissection. Tip edema, supratip definition, and fullness were blindly scored at 2-, 6-, and 12-month postoperative follow-up. Nasolabial angle was measured at 2 and 12 months postoperatively. Univariate analysis and multivariable regression modeling were performed. Supratip definition was significantly higher in group 1 at the 2-, 6-, and 12-month postoperative follow-up visits ( P < 0.05, P < 0.01, and P < 0.01, respectively). Tip edema and supratip fullness were significantly lower in group 1 at each time point ( P < 0.01). Nasolabial angle, and its modification between 2 and 12 months after intervention, did not differ in the 2 groups. All findings were confirmed when controlled for eventual confounders. The interalar ligament flap has proven to be versatile, effective, and consistently reliable in reducing tip edema and improving supratip definition. It may be tailored to the patient, partially folded to improve tip projection, or used to camouflage tip grafts. Therapeutic, III.
