DermaMatrix Acellular Dermis may provide a new option in rhinoplasty technology for surgeons. DermaMatrix, which was introduced to the surgical market in 2006, is made from acellular dermis, an innovative technological breakthrough substance which has been used as an alternative to Alloderm in rhinoplasty by Denver plastic surgeon Dr. Jeffrey Raval. Dr. Raval who presented the technique at the January 30, 2010 Annual Meeting of the American Academy of Cosmetic Surgery (AACS) in Orlando Florida.
Dr. Raval reports that “rhinoplasty poses a number of challenges- the ideal graft material being one of them.” Traditionally, Alloderm has been used as the grafting material in rhinoplasty surgeries. Unfortunately, despite its widespread use, Dr. Raval believes that Alloderm has not proven to be the “ideal grafting material” for several reasons. First, before being used, it has a short shelf life, and must be refrigerated. When used in a surgery, it requires a long rehydration time and displays reabsorption characteristics. DermaMatrix is derived from donated skin where the cells are removed to minimize inflammation or rejection at the surgical site and the acellular dermis is then freeze-dried for preservation.
DermaMatrix provides a better alternative. Dr. Raval reports that it rehydrates quickly, is uniformly soft and pliable after being rehydrated, passes the USP standard for sterility, is bacterially inactivated, has a three year shelf life at room temperature, has greater tensile strength, has a 90 percent consistency of thickness, is easier to surgically manipulate, and displays less reabsorption characteristics than Alloderm. These many advantages make it both easier to use and better for patients and can help the effects of rhinoplasty last longer.
Dr. Raval, who presented DermaMatrix at AACS, is a double board certified plastic surgeon and is regarded as the premiere revision rhinoplasty surgeon throughout the Western states. In addition to performing rhinoplasty revisions, which are often regarded as more complex than original rhinoplasty surgery due to the presence of scar tissue, Dr. Raval also treats the head and neck and performs both non-invasive and surgical procedures.

ReplyDeleteRhinoplasty is ideal for healthy, psychologically stable men and women who are seeking improvement but not perfection in their facial appearance. Most surgeons also consider age as a factor, preferring young patients who have completed their growth spurt.

Rhinoplasty is one such great for reconstructing the overall appearance of the nose in regard to its shape and size. The procedure of the Rhinoplasty is painless and very safe. This was great sharing about the Rhinoplasty here and nice discussion is going on.
