Area of Science:

  • Plastic Surgery
  • Biomaterials Engineering
  • Medical Device Design

Background:

  • Rhinoplasty is a common cosmetic procedure, particularly desired by Asians seeking more prominent nasal dorsum and tip.
  • Existing methods for nasal augmentation can lead to structural changes.
  • A novel approach is needed for safe and effective nasal tip plasty.

Purpose of the Study:

  • To introduce and evaluate a novel nasal tip plasty technique using three-dimensional (3D)-printed polycaprolactone (PCL) implants.
  • To assess the safety, efficacy, and patient satisfaction with this new method.
  • To compare the outcomes with conventional rhinoplasty techniques.

Main Methods:

  • A cohort of 22 patients underwent nasal tip plasty using 3D-printed PCL (Smart Ball®) implants.
  • Postoperative satisfaction was assessed via patient surveys.
  • Pre- and 1-year postoperative photographs were evaluated by three independent plastic surgeons.
  • Long-term follow-up (2-4 years) was conducted for all patients.

Main Results:

  • Patients reported high subjective satisfaction with a mean score of 3.67/4.
  • Plastic surgeons rated the outcomes highly, with a mean score of 4.47/5.
  • Ideal postoperative nasal tip rotation and projection were achieved in most patients.

Conclusions:

  • Three-dimensional (3D)-printed PCL (Smart Ball®) implants offer an optimal solution for nasal tip plasty, providing necessary length and volume.
  • This method allows for safe, simple, and precise shaping of the nasal tip.
  • A key advantage is the preservation of the original nasal structure, unlike conventional methods.
