The Effect of Platelet-Rich Fibrin on Nasal Skin Thickness in Rhinoplasty

Overview

Platelet-rich fibrin is made from the patient's own blood and contains growth factors. The authors hypothesized it might improve healing, reduce dead space and reduce swelling when used as a camouflage layer over the nasal framework, and measured skin thickness by ultrasound to test that.

Sections of note

• 38 patients who underwent open approach primary rhinoplasty, divided into a dorsal platelet-rich fibrin group and a control group.
• A platelet-rich fibrin membrane was laid over the bony bridge and the cartilage framework of the supratip area.
• Skin and subcutaneous soft tissue thickness were measured by linear superficial tissue ultrasound before surgery and at week 1 and month 3.
• Mean skin thickness over the supratip area was significantly higher in the control group at the week 1 assessment.
• No significant differences in nasal bridge mean skin thickness between the groups at either week 1 or month 3.
• No complications occurred in either group, including scarring, hematoma, infection, skin discoloration, or acne.
• The authors report a positive effect on postoperative swelling, especially early, and call for long-term investigation. Level of evidence 3.

What it means for a patient

• The measured benefit was confined to the area above the tip and to the first week.
• By three months, the two groups did not differ in skin thickness anywhere measured.
• The material comes from the patient's own blood, and no complications occurred in either group.
• Limits: 38 patients, one center, follow-up to 3 months, and skin thickness used as a proxy for swelling rather than a direct measure of appearance.

Why this paper matters

Early swelling determines how quickly a patient looks presentable and how long the final result stays hidden. An autologous membrane that reduces it would be low-risk. The effect measured here is small, localized and short-lived, and long-term effects are untested.

Terms

• Platelet-rich fibrin: A concentrate made from the patient's own blood, containing growth factors.
• Supratip: The area of the nose just above the tip.
• Dead space: A gap left between tissue layers where fluid can collect.
• Edema: Swelling caused by fluid in tissue.
• Superficial tissue ultrasound: Imaging with sound waves used to measure shallow tissue thickness.
