This paper describes a lip filling technique that administers hyaluronic acid using microcannulas. This technique considerably reduces the number of punctures compared to the conventional method, which uses needles. In addition, the microcannula’s blunt tip reduces the risks of intravascular injection of the substance and of disrupting key structures such as vessels and nerves. The results obtained by the authors confirm the less frequent occurrence of adverse effects and a high degree of physician and patient satisfaction.

Hyaluronic acid (HA) based cutaneous filling substances have become the treatment of choice for facial volumization. Hyaluronidase is a soluble protein that promotes the enzymatic degradation of HA. Commercially available preparations differ according to the substance's origin (bovine, ovine or human recombinant). Although cosmetic use has not yet been approved by the FDA, off-label use in dermatology is increasingly common. The purpose of the present article is to review the medical literature and prescribing information (package inserts) over existing commercially available products in order to provide an up-to-date view of the indications, dosage, injection techniques, and adverse effects.

Hematomas are common following cosmetic surgery. When minor, they are treated with observation only as they are most often reabsorbed. However, even with small collections of blood, if no early intervention is adopted, poor aesthetic outcomes may occur. Early drainage has been especially described in otorhinolaryngology and radiology journals. The authors present an approach to early treating hematomas. Special emphasis is given to the use of hyaluronidase, which is well known by dermatologists and plastic surgeons for its ability to dissolve hyaluronic acid, but its utility in the treatment of hematomas is not so commonly known by these experts.
