Cultured human fibroblasts in Restylane offer a stable dermal matrix for augmentation rhinoplasty. This method shows promising long-term results with high patient satisfaction and no complications.

Area of Science:

  • Plastic Surgery
  • Biomaterials Science

Background:

  • Cultured human fibroblasts in modified hyaluronic acid (Restylane) demonstrated in vivo stability in prior animal studies.
  • Hyaluronic acid-based fillers are commonly used in aesthetic procedures.

Purpose of the Study:

  • To evaluate the clinical efficacy of using autologous fibroblasts suspended in Restylane for augmentation rhinoplasty.
  • To assess the long-term stability, safety, and patient satisfaction of this novel approach.

Main Methods:

  • Eleven patients underwent augmentation rhinoplasty using subcutaneous implants of Restylane mixed with autologous fibroblasts.
  • A long-term follow-up exceeding one year was conducted for six patients.
  • Evaluation included nasal appearance, implant resorption, complications, and patient satisfaction.

Main Results:

  • Implants remained in situ with no significant resorption or loss of correction observed.
  • All patients reported satisfaction with the long-term aesthetic outcomes.
  • No complications were reported during the follow-up period.

Conclusions:

  • The use of autologous fibroblasts in Restylane appears to be a well-tolerated method for augmentation rhinoplasty.
  • This technique shows potential as an effective option for achieving stable, long-lasting rhinoplasty results.
