Lasers are effective tools for soft tissue surgery. The erbium, chromium: yttrium, scandium, gallium, garnet laser is a new system that incorporates an air-water spray. This study evaluates the cutting margins of this laser and compares healing with laser and conventional scalpel and punch biopsy-induced wounds.
New Zealand white rabbits were divided into serial sacrifice groups; the tissues were grossly and microscopically analyzed after laser and convential steel surgical wounding.
Wound margins were found to show minimal edge coagulation artifact and were 20 to 40 mm in width. Laser wounds showed minimal to no hemorrhage and re-epithelialization and collagenization were found to occur by day 7 in both laser and conventional groups.
The new laser system is an effective soft tissue surgical device; wound healing is comparable to that associated with surgical steel wounds. The minimal edge artifact observed with this laser system should allow for the procurement of diagnostic biopsy specimens.
激光是软组织手术的有效工具。铒铬钇钪镓石榴石激光是一种结合了空气-水喷雾的新系统。本研究评估了这种激光的切缘，并比较了激光与传统手术刀和打孔活检所致伤口的愈合情况。
将新西兰白兔分为系列处死组；在激光和传统钢制手术致伤后，对组织进行大体和显微镜分析。
发现伤口边缘显示出最小的边缘凝固伪像，宽度为20至40毫米。激光伤口出血极少或无出血，在激光组和传统组中，均在第7天发现重新上皮化和胶原化。
新的激光系统是一种有效的软组织手术器械；伤口愈合情况与手术钢刀伤口相当。该激光系统观察到的最小边缘伪像应有助于获取诊断性活检标本。
