Novel method for correcting cephalic rotation in Asian nasal tip plasty.

Abstract

To correct nasal tip cephalic rotation, SEG made of cartilage or Medpor are often used in rhinoplasty. These techniques require extensive experience for the surgeon, and not all patients can accept this procedure. In this research, we introduce a new method to correct nasal tip cephalic rotation that is relatively simple and rapid. Fifty-nine patients who had rhinoplasty using our scaffold were enrolled in the study between January 2020 and January 2021. The authors evaluated the change of nasolabial angel by photogrammetry using standardized clinical photogrammetric techniques. Patients' satisfaction regarding postoperative results was also surveyed. The mean postoperative follow-up duration was 12 months. No complication (infection, extrusion, and displacement) was happened in all patients. Analysis showed our scaffold can correct nasal tip cephalic rotation effectively (98.61±1.21 preoperatively and 89.68±0.99 postoperatively, P<0.0001). And the patient satisfaction rate is 98%. We constructed an integrated scaffold by simply folding and suturing a high-density polyethylene sheet (Su-Por) sheet to correct nasal tip cephalic rotation. Using the scaffold we designed, we did not need to alter the structure of the nasal septum, which reduced the operative duration and simplified the surgical procedure.
