| English abstract | The use of laser Neodymium-Yttrium-Aluminium-Garnet (Nd-YAG) as an auxiliary tool on rejuvenation provided a refining of the traditional technique. This laser procedure show satisfactory results with technical improvement and postoperatory recovery. OBJECTIVES: The aim of this study is to show the histological and morphometrical changes found in human eyelid tissue after the use of laser Nd-YAG and its comparision to the normal structure. MATERIAL AND METHODS: Nine female patients underwent laser Nd-YAG application on their right eyelid. The left eyelid was taken by control-tissue, free of any kind of procedure. It was made many applications of the laser and on the last day, it was made a bilateral biopsy. The morphometrical criteria appraised were: epidermal denseness measure, subepidermal area free of injury, colagen degeneration and total dermal density. RESULTS: In those areas whose underwent laser the epidermal measure was of 33,53 micrometers (µm) and on the normal tissue, was of 29.61µm (p = 0.1099). The subepidermal measure was, on average, of 40.93µm on right side and of 36.27µm on left side (p = 0.1373). The colagen degeneration measure on the right side was of 293.54µm and on the left side was of 292.22µm (p = 0.4835). On the procedure site, the total dermal measure was of 681,48µm and on the free site, it was of 664.14µm (p = 0.3492). DISCUSSION AND CONCLUSIONS: Despite the clinical changes observed after laser Nd-YAG therapy, there were neither histological nor morphometrical significative changes |

DISCUSSÃO E CONCLUSÕES: Apesar da diferença clínica observada após tratamento de lesões de envelhecimento em pálpebra de humanos com o uso do laser Nd-YAG, nota-se que não houve diferença histológica ou morfométrica após tal procedimento |
