The use of fillers for camouflage after surgical rhinoplasty or during medical rhinoplasty process represent an attractive technique which allows to avoid or to delay surgical time often dreaded by the patients. This technique apparently quite simple, must be applied carefully in order to avoid possible complications that can sometimes be very serious. Through their seven years of experience, the authors have selected absorbable type of products: hyaluronic acid or calcium hydroxylapatite, both approved by ANSM. Preference is given to microcannulas (27G) over needles and injection techniques through multiple tunnels fitted with small fragmented boluses. Due to possible Tyndall effect and skin necrosis risk, a one-shot injection with a lot of product should be avoided. Calcium hydroxyapaptite is preferred for the dorsum area while hyaluronic acid is recommended for the tip. The authors also relate the major encountered complications and describe the appropriated treatments. Nevertheless the strict application of the described technique represents the best way to prevent adverse complications.
