Abstract
The objective of this study was to determine output power for skin incision in 0.3 mm spot diameter $CO_2$ laser by measuring (1) the wound depth, (2) initial dermal tissue damage, (3) degree of wound healing at different power (4W, 5W and 6W) in beagle dogs. Three healthy 2-year-old beagle dogs were used. Four 2 cm straight skin incisions were made with 0.3 mm spot diameter $CO_2$ laser on the each dog's both side of dorsal midline in three beagle dogs. The skin incisions were performed for $10{\sim}15$ seconds for same dosage. And then each wound was closed with surgical stapler. At 0, 3, 7 and 14 days after initial wounding, each wound was taken for histological observation. On macroscopic and microscopic observation, initial incisional wound did not show difference in three group. And also re-epithelialization, dermal tissue damage and inflammatory response did not show significant difference among groups. This study reveals that 4W, 5W and 6W may be suitable output power in 0.3 mm spot diameter $CO_2$ laser for the skin incision in beagle dogs.
