Surgical defects on the scalp require closure via various techniques of suture placement. A traditional technique requires both dermal (deep) and epidermal (superficial) placement of sutures to close the defect; this is referred to as intermediate or complex linear repair. However, the scalp is a location with high tension, and thus the closures take an hour or longer to perform. A type of suture placement referred to as the "pulley stitch" requires placement of a few stitches along the defect. The pulley stitch can be used in areas of high tension to close a large defect. The purpose of this study is to compare the scar results and time taken to perform scalp closures via only pulley stitches or via intermediate/complex linear repairs. To my knowledge, no such study has been performed to compare the two techniques. Such a study would be useful in demonstrating comparable scar appearance and reduce the time to perform scalp closures.
The goal of this study is to establish the safety of high fluence LED-RL from 160 J/cm2 up to 640 J/cm2 in healthy subjects. The hypothesis is that high fluence LED-RL phototherapy is safe in human skin.
The traditional open appendectomy in the clinical effect is not prefect, and for a long time there is no measurable improvement. The application of abdomen CT before surgery provides a new approach to the incision and new perception. In a randomized controlled trial of modified incision versus traditional incision. Length of hospital day was the primary terminus, while operating time, postoperative complication, scar and time to resume normal activity and work as secondary terminus.
This study aims to determine if the 595nm Pulsed dye laser, the combined 595/1064nm Multiplex laser or no treatment results in a better outcome in the quality of the surgical scar using the multiplex cynergy laser, starting treatment the day of suture removal.
The investigators are doing this research study to learn about how the skin heals after many microscopic skin biopsies are collected. Skin-grafting is a life-saving procedure for people with large area skin wounds caused by burns or trauma. Conventional autologous (self) skin grafting techniques require the creation of large donor site wounds, causing numerous complications including pain, infection, blistering, discoloration, and scarring. Based on previous research, many of these adverse effects can be improved, or even eliminated, by harvesting skin tissue in very small biopsies. These "micro-biopsies" are less than the size of a sewing pin. Then, they are put back together into a skin graft. This concept is based on clinical observations from fractional photothermolysis laser therapy, an FDA approved laser that has been previously developed by the investigators research group for the treatment of scars and ageing skin. With this laser technique, thousands to millions of small burns are produced by laser on a patient's skin, and the skin responds by healing the damaged areas to create new healthy skin within days and without scarring. Although the results of laser treatment are well-known, it is not known what happens when we harvest the skin using needles instead of using the laser to cut the skin. The investigators also would like to understand how the body heals the skin. Understanding how this works helps in understanding wound healing, and may lead to future treatments for healing large wounds, disfiguring burn scars, and preventing scar formation. A tummy tuck (abdominoplasty surgery) is done to remove excessive skin of the belly. This is an elective surgery, in other words, it is optional and usually done for cosmetics reasons (to improve the appearance). The skin of the belly that is removed during an abdominoplasty surgery (tummy tuck) is discarded. The skin of the area removed is called "pre-abdominoplasty skin". The investigators would like to study the effects of the micro-biopsies on pre-abdominoplasty skin to exam how the skin heals over time and to study the skin that will be removed during the abdominoplasty surgery. This is a pilot study. Pilot studies are done on a small group of subjects to learn if a larger study would be useful. The investigators are asking subjects to take part in this study who are healthy with an abdominoplasty surgery (tummy tuck) scheduled at Massachusetts General Hospital (MGH) by a plastic surgeon . The investigators will enroll about 28 subjects in this research study, all at MGH. The Department of Defense is paying for this study to be done.
Compare the efficacy and safety profile of microneedling radiofrequency and that of bipolar radiofrequency treatment for acne scar.
The purpose of this study is to determine the efficacy of the 1064nm Neodymium yttrium aluminum garnet (Nd:YAG) laser (Laser Genesis, Cutera TM) in the treatment of surgical scar after direct brow lift.
Traumatic wounds inflict small- and large-fiber sensory nerve damage, causing neuropathic pain in scar tissue. Autologous fat grafting has been clinically shown to improve scar quality, but scantly study has explored its effects on pain. The aim of the study was to survey its effect on pain.
