The Effect of Autologous Fat Grafting on Edema and Ecchymoses in Primary Open Rhinoplasty

What this paper says

Comparing 33 patients who received fat grafting during rhinoplasty against 29 who did not, the fat-grafted group had 7.29 square centimeters less bruising at 2 weeks, with no significant difference in swelling.

Overview

Fat taken from the patient's own body is used as a soft tissue filler and has been reported to aid wound healing. The authors added fat grafting during primary open rhinoplasty and tested whether bruising and swelling resolved faster, measuring both on three-dimensional images.

Sections of note

Retrospective review of rhinoplasty patients compared by presence or absence of concurrent fat grafting.
Three-dimensional images were analyzed with Mirror software; bruises were outlined with a magnetic lasso and their area measured, and swelling was measured volumetrically.
Measurements were taken at 2 and 6 weeks after surgery; significance set at P below 0.05.
62 patients included: 33 (53.2%) received fat grafting and 29 (46.8%) did not.
Age, gender, surgical approach, and osteotomy distribution were similar between the groups.
Early interval results: 7.29 square centimeters fewer bruises, P below 0.001, and 0.73 cc less swelling, P 0.68.
At 6 weeks: 1 cc less swelling, P 0.36, with negligible differences in bruising.

What it means for a patient

The measured benefit was to bruising in the first weeks, and it was statistically strong.
Swelling did not differ significantly at either time point.
By 6 weeks the bruising difference had disappeared, as bruising resolves anyway.
Limits: 62 patients, retrospective rather than randomized, one practice, and no reported data on donor site or fat graft complications.

Why this paper matters

Visible bruising is the main constraint on returning to normal activity after rhinoplasty, and this reports a measurable reduction using the patient's own tissue. Objective image-based measurement is stronger than observer grading. The retrospective design means the two groups were selected rather than assigned.

Terms

Autologous fat grafting: Transferring the patient's own fat from one site to another.
Ecchymosis: Bruising under the skin.
Edema: Swelling caused by fluid in tissue.
Volumetric measurement: Calculating the volume of a structure from a 3D model.
Osteotomy: A controlled surgical cut through bone.

From the abstract

“Autologous fat is a safe and effective soft tissue filler. Recent evidence also suggests improved wound healing and immune modulation with fat grafting. Objectives: The aim of this study was to describe a novel technique utilizing fat grafting during primary open rhinoplasty. We hypothesize a more rapid resolution of…”
