Hyaluronic acids.

Abstract

Hyaluronic acids (HAs) are the most versatile fillers on the market. Since their approval in Canada in 1998 and the United States in 2003, applications for facial contouring have been varied, with predictable and outstanding results. Numerous publications support their safety, durability, longevity, and application to reconstructive and cosmetic procedures for both surgical and nonsurgical applications. The incidence of complications is low, and the treatment of complications is relatively straightforward with the use of hyaluronidase. This article discusses the uses of the HAs in general, with regard to the various particles sizes (Restylane, Restylane Fine Lines, Perlane, Juvederm 18, 24, 30), which are available in Canada and will be available in the United States in the fall of 2006.

Minimal scars for scalp surgery.

BACKGROUND: As is well known, scars are the indelible ransom of any surgical procedure and the major obstacle confronting patients and surgeons from an aesthetic standpoint. Many patients opt against a surgical solution for this reason only or choose surgical techniques which are sometimes open to question, such as follicular unit extraction. OBJECTIVE: The objective was to change from narrow scars created at present to that of scars minimal to the naked eye, the subject of this article. METHODS: Following a clinical study of more than 100 cases, I present a new surgical technique enabling for the first time the creation of minimal scars to the naked eye. This technique is based on the role of the galea responsible for tension and secondary widening of scars in classical techniques and explains hypodermic incision to eliminate this wound tension, as well as the specific role of deepithelialization of the lower lip of the wound. RESULT: A minimal scar to the naked eye was obtained in most cases with this technique. CONCLUSION: Owing to this major improvement, I have switched from the conventional closure techniques to this new one.
