Regenerative Biologics in Revision Rhinoplasty: Emerging Roles of Stem Cells, Nanofat, Platelet-Rich Plasma, and Exosomes in Soft Tissue Optimization and Healing

Overview

This is a narrative review with no patient series. The authors describe regenerative medicine as an emerging approach in facial plastic surgery over the past decade and argue it is especially relevant in revision rhinoplasty, where damaged blood supply, scar and contracture limit what surgery alone can achieve. The abstract names four biologic adjuncts and frames them as cellular support added to mechanical repair.

Sections of note

• Regenerative medicine is presented as "a new paradigm" for skin quality and longevity in facial surgery.
• Revision rhinoplasty is singled out because vascular compromise, scarring and contracture diminish results.
• Adjuncts covered: stem cells, nanofat, platelet-rich plasma (PRP), exosomes.
• The stated role is to complement structural correction with cellular support.
• No outcome data, doses or protocols are given in the abstract.

What it means for a patient

• These treatments are aimed at the skin and soft tissue over the nose, not at the cartilage framework.
• They are described as emerging; the abstract does not present evidence that they change surgical results.
• Senior author Toriumi is a leading revision surgeon, so this reflects practice at a high-volume centre rather than proven standard care.

Why this paper matters

It signals that regenerative adjuncts are entering mainstream revision-rhinoplasty discussion. Limits: review, no data, and the field lacks controlled trials.

Terms

• Nanofat: the patient's own fat, mechanically broken down into a fluid rich in regenerative cells.
• Platelet-rich plasma (PRP): concentrated platelets from the patient's blood, used to promote healing.
• Exosomes: tiny vesicles released by cells that carry signalling molecules.
• Contracture: tightening of scarred skin that shrinks or distorts the nose.
