•The procedure:
The face will be washed thoroughly immediately before the procedure.
Disinfection with alcohol 70% will be done.
A topical anesthetic cream will be applied to the face and left for 30 minutes then it will be removed.
The obtained platelet rich plasma will be delivered by intradermal method using mestherapy needle.

During the surgery, patients in group S receive additional fluids (400 ml of normal saline or 200 ml of colloid) when SVV is less than 13.

Patients in group C receive additional fluids (400 ml of normal saline or 200 ml of colloid) when CVP is less 8 during the surgery.
