EFFECTS OF THE MICRO REINJECTION OF AUTOLOGOUS ADIPOSE TISSUE IN THE FACE OF PATIENTS WITH SYSTEMIC SCLEROSIS

EFFECTS OF THE MICRO REINJECTION OF AUTOLOGOUS ADIPOSE TISSUE IN THE FACE OF PATIENTS WITH SYSTEMIC SCLEROSIS

This prospective single-center study evaluates a current care procedure. It includes 14 patients diagnosed with SSc according to the ACR/EULAR criteria or the Leroy & Medsger criteria of the disease. Patients are enrolled if they wish for a therapeutic care of their face, have a Mouth Handicap in Systemic Sclerosis (MHISS) score greater than 20 (scale 0-48), a modified Rodnan skin score upper or equal to 1 on the face (scale 0-3), and a mouth opening less than 55 millimeters. They should not have anticoagulant, anti-platelets aggregation medication or a daily steroid dose upper 20mg per day. Their BMI should exceed 17.

Micro fat grafting is a minimally invasive and usual procedure performed under local anesthesia. Fat tissue is harvested (around 50 milliliters) using a 14 gauge or 2 mm diameter cannula from areas around the knees, the abdomen or the hips under a gentle aspiration. Lipoaspirated fat is then filtrated by the PureGraft system that offers a sterile, closed, single-use system, leading to a fast, consistent and controlled preparation. Then, 10 to 25 milliliters of this purified fat product is transferred through a 21 gauge or 0.8 mm diameter cannula in two or four points of the face, with the entry points located around the mouth.

Inclusion Criteria:

• Patients older than 18 or younger than 80 years.

• Mouth opening (inter-incisor distance) <5.5 cm
• Wishing to receive surgery at the face.

Exclusion Criteria:

• Less than 18 or greater than 80 age.
• Decaying history of abdominal surgery.
• Body mass index lower than 18.
• Coagulation disorders.
• Allergy to Xylocaine.
• Greater than 20mg / d steroids.
• Severe infection.
• Inmates.
• Pregnant women.
• Adults protected by law (under guardianship and trusteeship).
