Using Dermofat Grafting in Revision Rhinoplasty

Area of Science:

• Plastic Surgery
• Reconstructive Surgery
• Nasal Aesthetics

Background:

• Revision rhinoplasty often involves complications from alloplastic materials.
• Autologous tissues like dermofat are alternatives but face challenges in graft absorption, shaping, and donor site morbidity.
• Existing techniques require refinement to overcome these limitations.

Purpose of the Study:

• To present surgical techniques for dermofat grafting in revision rhinoplasty.
• To overcome challenges associated with graft absorption, shaping, and donor site morbidity.
• To evaluate the efficacy and safety of an advanced dermofat grafting technique.

Main Methods:

• Retrospective study of patients undergoing autologous dermofat grafting for revision rhinoplasty (excluding primary cases).
• Utilized mid-sacral dermis as the donor site, resecting fat in a wedge shape.
• Applied a molding technique for graft shaping and height, minimizing absorption and flap tension.
• Assessed aesthetic outcomes via blinded comparison of pre- and postoperative photographs.

Main Results:

• Out of 331 dermofat grafting cases for revision rhinoplasty, 25 required revisions.
• Complications included graft over-absorption (5), over-correction (1), deviation (9), donor site scar widening (1), and wound dehiscence (8).
• One case developed an inflamed sinus.

Conclusions:

• The advanced dermofat graft technique, using appropriate donor sites and subdermal fat, yields favorable results.
• A specific molding technique and proper donor site management mitigate critical disadvantages.
• This technique provides a safe and effective alternative for revision rhinoplasty.
