Decreased splatter in dermabrasion.

OBJECTIVE: To compare a new dermabrasion instrument equipped with a metal shield and hydration-suction apparatus with the standard instrument, with specific attention to the exposure of operating room personnel to potentially hazardous particles. DESIGN: A surgical trial with each of the instruments was performed with a skin model. The splatter caused by the 2 instruments was evaluated and compared statistically and graphically. SUBJECTS: Female hairless guinea pigs (450 g) were used as a skin model. INTERVENTIONS: Ten guinea pigs were treated with the standard dermabrading instrument, and 10 were treated with a shielded suction-irrigating dermabrader. The splatter was analyzed by counting the number of particles landing on strategically placed glass slides. Evaluations of histologic cross-sections of the dermabraded skin were compared in a blinded fashion. RESULTS: Statistical and graphic analysis showed the number of potentially hazardous particles generated by the suction dermabrader to be significantly less than that generated by the standard dermabrader. Histologic sections showed no difference between the 2 subsets. CONCLUSION: The new shielded suction-irrigating dermabrader provides comparable surgical results while significantly decreasing exposure to potentially hazardous splatter particles.

Bipolar scissors in facial plastic surgery.

BACKGROUND: Many methods are available to the facial plastic surgeon for elevating and separating tissue, from cold steel to monopolar cautery to various laser-cutting technologies. Bipolar cautery has replaced monopolar cautery as the optimal hemostatic technique because of its decreased tissue damage and improved capabilities. Bipolar scissors concurrently offer a dissecting technique with hemostatic capability. Little exists in the otolaryngology literature on the use of bipolar scissors for soft tissue dissection. OBJECTIVE: To describe our experience using bipolar scissors in a variety of facial plastic and reconstructive procedures. SETTING: Tertiary care referral academic center. DESIGN: We retrospectively reviewed 78 procedures performed using bipolar scissors between June 1997 and August 1999. In facial plastic cosmetic surgery, bipolar scissors were used 31 times for deep plane face-lifts and 16 times for endoscopic browlifts. In facial plastic reconstructive surgery, bipolar scissors were used in 15 radial forearm free flaps, 10 fibula osteocutaneous flaps, 3 rectus abdominis free flaps, and 3 latissimus dorsi myocutaneous free flaps. RESULTS: In all procedures, bipolar scissors facilitated the dissection. By allowing for a drier field, less time was required to elevate the flap and obtain hemostasis. Complications were not increased compared with historical controls. In the harvesting of fibula osteocutaneous free flaps, use of bipolar scissors allowed harvesting without use of a tourniquet. CONCLUSION: Bipolar scissors, a new technology in facial plastic surgery, allow the same control as sharp dissection and provide simultaneous hemostasis.

Keloid scar of the face.

Although all the consultants agreed that this patient deserved to be treated, they disagreed as to the method. Dr. Wise suggested excision of the scar with postoperative irradiation. Dr. Thomas would excise the scar, inject the lesion with steroids intraoperatively and postoperatively, and apply a pressure dressing. Dr. Cook would not operate at all and favored intralesional injection of steroids. When used, Kenalog was the steroid preparation of choice. Dr. Wise would not use steroids in this situation because of the possible complications of skin atrophy, change in pigmentation, and telangiectasias. Dr. Thomas would avoid low-dose irradiation for fear of inducing a head and neck malignancy. Dr. Cook would avoid all surgical intervention, believing that it would only compound the present problem. All consultants agreed that the patient deserved close follow-up, and that he was at risk for similar scar formation in the future. They also pointed out the genetic predisposition for his offspring to have similar problems.
