Hyaluronic Acid IIPattern of Intercellular Space
The intercellular space of the skin is filled by collagen fibers which are located in a matrix of polysaccharides (=hyaluronic acid).

Hyaluronic Acid IIIMicrostructure, Properties
An important function of hyaluronic acid is its property of water retention.

Bacterial Biofilm I
A biofilm is any group of microorganisms in which cells stick to each other on a surface. These adherent cells are frequently embedded within a self-produced matrix of extracellular polymeric substance (EPS). Biofilm extracellular polymeric substance, which is also referred to as slime (from: https://en.wikipedia.org/wiki/Biofilm)
from:https://en.wikipedia.org/wiki/BiofilmResp.from: Looking for Chinks in the Armor of Bacterial Biofilms Monroe D PLoS Biology Vol. 5, No. 11, e307 http://biology.plosjournals.org/perlserv/?request=slideshow&type=figure&doi=10.1371/journal.pbio.0050307&id=89595

Bacterial Biofilm II
“Biofilms are ubiquitous. Nearly every species of microorganism, not only bacteria have mechanisms by which they can adhere to surfaces and to each other. Biofilms will form on virtually every non-shedding surface in a non-sterile aqueous (or very humid) environment.”
“Biofilms can grow in showers, pipes, on teeths, catheters, contact lenses, heart valves, etc.”
https://en.wikipedia.org/wiki/Biofilm

Bacterial Biofilm IIIin Soft Tissue Fillers
Bacterial biofilm formation and treatment in soft tissue fillersMorten Alhede et al. April 2014Pathogens and Diseasedoi: 10.1111/2049-632X.12139
„…Evaluation of treatment strategies showed that once the bacteria had settled (into biofilms) within the gels, even successive treatments with high concentrations of relevant antibiotics were not effective. Our data substantiate bacteria as a cause of adverse reactions reported when using tissue fillers, and the sustainability of these infections appears to depend on longevity of the gel. Most importantly, the infections are resistant to antibiotics once established but can be prevented using prophylactic antibiotics. …“

Consequences
Think!
Would you like to have a permanent filler?
Do you inform your patients who ask for permanent fillers about foreign body reactions, inflammations, infections, fistulas?
Do you inform about alternatives (hyaluronic acid, fat transfer)? Antibiotic prophylaxis?

Autologous Fat TransferResorption
Causes of trauma to transplanted fat grafts By suction of fat (mechanical, high vacuum) By preparation of graft (mechanical, drying) By injection of fat graft (high pressure) By late ischemia within the body (high tissue pressure)
Rates of Resorption in Literatur 20 - 100%Own Investigations: 55,6% (47 - 68%)
![Page 30: Filler Materials Medical Aspects Prof. Dr. med. P. Graf Munich](https://reader035.vdocuments.net/reader035/viewer/2022081519/56649cc45503460f9498d522/html5/thumbnails/30.jpg)
Autologous Fat TransferMinimization of Resorption
Avoid potentially damaging substances (Adrenalin?) Gentle suction (diameter of canula, size of vacuum) Atraumatic preparation of fat graft Careful preparation („ Cleaning“) of aspirated fat Careful Injection (short, thick canula) Good dissemination of graft Avoid high tissue pressure
Atraumatic treatment is critical forRates of resorption (=success) of fat transfer
