Effect of Nasal Tip Surgery on Asian Noses Using the Transdomal Suture Technique

Abstract

The past two decades have ushered in a new era of nasal tip surgery. The new philosophy focuses on preserving and reorienting nasal tip structures. Modern suture techniques can give predictable results because of more precise suture placement. Only a few reports, however, have objectively evaluated the suture techniques for Asians. Accordingly, the authors aimed to assess the efficacy of the tip suture technique through projection and rotation analysis. We focused on transdomal sutures because they involve one of the most popular suture techniques. Preoperative and postoperative photographs of 85 patients who underwent rhinoplasty at Inha University Hospital between June 2002 and June 2004 were analyzed. The patients were categorized into four groups according to the techniques used. Tip projection was measured by the modified Heuzinger's method and tip rotation by the nasolabial angle. The pre- and postoperative indexes were compared within each group and among the four groups. Paired and unpaired t tests were used for statistical analysis. When the pre- and postoperative indexes were compared within each group, only the combined technique (transdomal suture with onlay graft) showed significant tip projection improvement. All tip surgeries resulted in insignificant tip rotation increase. Comparison among the four groups showed no significant difference based on the type of tip surgery performed. The suture technique has many advantages, although it has some limitations with Asian noses, especially if used alone. Therefore, we recommend using the suture technique in combination with other tip surgical procedures, such as onlay grafts, to achieve significant tip projection.
