Long-term results after restoring nasal tip support using auricular cartilage as an intercrural columellar strut graft: the "I-Beam" technique.

Abstract

The lack of nasal tip support resulting in poor protection and projection of the nose is a common cause of nasal obstruction and cosmetic impairment. Although septal cartilage is preferred for restoration of nasal tip support, there is often not enough septal cartilage available. We describe an intercrural columellar strut graft in a circumferential soft tissue pocket: the I-Beam technique. In this cohort study over an 8-year period the clinical and biometrical long-term results after restoration of nasal tip support with an autologous auricular cartilage graft, the I-Beam technique, is evaluated. Out of the 72 consecutive septorhinoplasties with the I-Beam technique, we studied 66 patients in the median long-term follow-up of 89 months. In all patients a significant improvement in nasal tip projection was found. A functional improvement in nasal breathing was achieved in 86%. The overall satisfaction with the I-Beam graft was of 83%. No deterioration in smell perception was found after surgery. The I-Beam technique using back-to-back sutured autologous auricular cartilage is a safe and effective technique and gives long-term structural support and enhances tip projection.
