  • Title: Nasal Elongation with Septal Half Extension Graft: Modification of Conventional Septal Extension Graft Using Minimal Septal Cartilage.
    Author: Lee SH, Lee HB, Kang ET.
    Journal: Aesthetic Plast Surg; 2018 Dec; 42(6):1648-1654. PubMed ID: 30218153.
    Abstract:
    BACKGROUND: In Asian rhinoplasty, a septal extension graft can be used for both tip projection and derotation of the alar cartilage. However, patients often do not have enough harvestable septal cartilage to create the septal extension graft. We therefore devised a method with which to fix the derotated alar cartilage with a small amount of septal cartilage. METHODS: From January 2012 to December 2016, 23 patients underwent short nose correction with a septal half extension graft made of septal cartilage and were postoperatively monitored for at least 6 months. The alar cartilage was completely separated from the adjacent structures, especially the scroll area and hinge complex, for caudal derotation. The septal half extension graft was then harvested from the septal cartilage and secured to the caudal septum and the lateral crura of the alar cartilage. Photographs of the patients were compared immediately before surgery and 1 year after surgery. RESULTS: Of the 23 patients, 21 (91%) had satisfactory results without short nose recurrence. Two (9%) patients developed recurrence: undercorrection and poor tip projection in one patient each. Aesthetic assessment of short nose correction was performed by comparing the columellar labial angle before and after surgery. Our method reduced the columellar labial angle by 6.2% (paired t test, p < 0.05, t = 31.698). CONCLUSION: In patients who cannot undergo conventional septal extension graft due to insufficient amounts of septal cartilage, the septal half extension graft could be a promising alternative technique for short nose correction with minimal septal cartilage harvesting.
