Background:
The currently recommended strategies for short nose elongation were designed primarily for the Caucasian nasal framework. For Oriental patients, more elongation often is required because a hypoplastic septal cartilage requires more elongation, resulting in a higher risk of complications. This report proposes a modified technique for Oriental nose elongation, which adjusts the pressure points after nasal elongation using an L-shaped implant.
Methods:
Between January 2007 and December 2009, 58 patients underwent Oriental nose elongation using an L-shaped, porous, high-density polyethylene sheet implant. Augmentation rhinoplasty and conchal cartilage shield grafts were performed depending on the nasal shape. Pre- and postoperative nasal length, height, and projection as well as columella-labial angle, columella-lobular angle, and nasal tip angle were measured and compared. A patient satisfaction survey was performed postoperatively. All occurring complications were recorded.
Results:
The postoperative nasal length was significantly elongated from 47.0±10.4 mm to 49.3±10.1 mm (p=0.003), and the nasal height increased significantly from 48.5±9.1 mm to 50.4±8.5 mm (p=0.011). The initially obtuse columella-labial angle improved significantly from 100.8°±12.1° to 92.5°±15.5° (p=0.014). No significant changes were found regarding nasal projection, nasal tip angle, or columella-lobular angle. The majority of the patients (91.3%) were highly satisfied or satisfied with the aesthetic results. A major complication in terms of implant exposure was observed in one case. The minor complications included stiffness of the nasal tip (3 patients) and tip redness (1 patient).
Conclusions:
In Oriental nose elongation, the use of an L-shaped graft is a feasible and safe treatment option that allows for an excellent aesthetic outcome and reduces the incidence of complications.
