Y-Columellar Strut Graft: A Method for Reconstructing the Nasal Tip in Primary and Revision Rhinoplasty.

Abstract

Several techniques have been proposed to modify tip shape and projection, both in congenital and in acquired nasal tip deformities. The authors describe a novel technique, the Y-columellar strut graft (Y-strut), which uses auricular cartilage to increase tip projection and restore contour in primary or revision rhinoplasty. Thirty-seven patients with congenital, acquired, or iatrogenic nasal tip malformation underwent reconstruction with Y-strut using short or long upper limbs ("wings"). The short wing variant was used to increase tip projection in primary rhinoplasty, and the long wing variant was used to corrected iatrogenic deformities of alar cartilages in revision rhinoplasty, improving contour and projection. Frontal, oblique, and lateral views before and after surgery were analyzed in blinded fashion at 1 year for tip shape and projection. Statistical analyses compared demographic characteristics, deformity type, and nasolabial angle before and after surgery to evaluate aesthetic outcome. All patients demonstrated improved nasal tip position. The Y-strut increased the nasolabial angle, reflecting tip rotation, and findings were independent of type or location of deformity ( P < 0.00001). No statistically significant differences were observed in comparisons of the short- versus long-wing technique. Three patients with congenital nasal tip malformations showed mild tip deviation at 1-year follow-up, and one had mild dorsal irregularity unrelated to grafting; no negative outcomes were observed in revision rhinoplasty patients. The Y-columellar strut graft is a reliable and versatile rhinoplasty technique using paired, symmetric grafts fashioned from auricular cartilage to correct tip deformities. Therapeutic, IV.
