Microfat Grafting in Nasal Surgery

Area of Science:

• Plastic Surgery
• Regenerative Medicine
• Dermatology

Background:

• Injectable fillers can cause complications like necrosis.
• Autologous tissue grafts offer advantages over synthetic fillers.
• Nasal procedures require careful consideration due to fragile skin.

Purpose of the Study:

• To evaluate injectable autologous microfat grafting for secondary nasal deformities.
• To assess the efficacy in correcting minor and severe nasal irregularities.
• To determine safety and patient satisfaction with the procedure.

Main Methods:

• A 5-year study involving 313 patients with secondary nasal deformities.
• Microfat grafting was performed, with excess fat cryopreserved for future use.
• Injection volumes varied from 0.3–0.8 mL for minor irregularities to 1–6 mL for major defects per session.

Main Results:

• Satisfactory results were achieved in all patients with minor irregularities after 1–3 injections.
• Patients with severe irregularities required 3–6 injections, reporting high satisfaction.
• Severe traumatic skin damage necessitated 6–16 injections for successful reconstruction.

Conclusions:

• Autologous microfat injection is a safe and effective technique for nasal irregularities.
• The procedure demonstrates good long-term results and high patient satisfaction.
• Microfat grafting offers a reliable solution for secondary nasal deformities and skin damage.
