Conventional open carpal tunnel release effectively relieves symptoms, but involves pain and fairly long recovery time. A relatively new technique of endoscopic carpal tunnel release as described by Chow has been carried out on 20 hands in 16 patients. The endoscopic approach allows earlier return to normal activities with less postoperative pain than conventional or open release.
Scar tissue formation along the cut edges of the transverse carpal ligament has been found to be among the primary causes for persistent median nerve compression following carpal tunnel release with the steel scalpel. Since laser surgery has been shown to be effective in reducing incisional inflammatory reactions, hypertrophic scarring, and postoperative pain and edema, in achieving better hemostasis, the application of the carbon dioxide laser may be a more efficient surgical tool than the steel scalpel for carpal tunnel release. In 46 cases of carpal tunnel syndrome, the carbon dioxide laser was utilized to vaporize the transverse carpal ligament and seal its edges. The patients were then reevaluated at 1 week, 2 weeks, 6 months, 1 year, and 2 years. No intraoperative complications were encountered. Patients reported minimal postoperative pain, rapid return of sensibility, decreased paresthesia, and increased motor function. After 2 years, there have been no recurrent symptoms of median nerve compression in these patients.

A representative series of cases are presented which demonstrate secondary reconstructive plastic surgery procedures for the burn victim utilizing microvascular free flaps, regional flaps, and specialized skin grafts. The unstable burn scar of the lower extremity could be managed either by a microvascular free-flap transfer, a muscle transfer, a myocutaneous flap transfer, or a reverse dermis graft, or overgrafting. In the present day, there are many treatment modalities available to us. Long-term wearing of the Jobst pressure stocking is essential in many cases to minimize the hypertrophic burn scar. In our experience, Kenalog injection into a hypertrophic burn scar always has resulted in improvement of the condition although it is usually necessary to give multiple injections into the hypertrophic burn scar at eight week intervals. We have never known Kenalog to fail to improve a hypertrophic scar by flattening it out to a significant extent, but it may take a year or more of injections to accomplish this goal. Microvascular surgery is most definitely a team effort requiring at least two fully trained microvascular surgeons, plus experienced operating room personnel. One microvascular surgeon harvests the free flap, and the other microvascular surgeons prepares the recipient area. Both microvascular surgeons participate in the multiple anastomoses that are required. A microvascular laboratory is essential to the success of a microvascular team, and constant practice is mandatory to maintain and enhance these precision skills. The primary burn surgeon ideally must always keep in mind ways to minimize functional and aesthetic deformity and to continue to improve the quality of life of the burn victim.
