ABSTRACT
BACKGROUND: The infrared coagulator, a by-product of laser technology, has been used in dermatology in a variety of settings. During hair transplantation sessions, we observed a significant reduction of the donor ellipse width while performing hemostasis with the infrared coagulator. OBJECTIVE: Quantitative assessment of the donor wound width after infrared coagulator use, and correlation to the number of previous transplant sessions and patients' age. METHODS: Twenty-four patients (22 men, two women) underwent hair transplantation. The infrared coagulator was utilized for hemostasis with a pulse duration of 2.5 seconds. RESULTS: The infrared coagulator produced an average donor area decrease of 42%, while achieving rapid hemostasis. No correlation was demonstrated to number of previous transplant sessions or patients' age. CONCLUSIONS: The infrared coagulator significantly decreases the donor wound width while providing hemostasis. Advantages include the potential of larger donor strip harvest, minimal tissue manipulation, and less traumatic closure.
