dc.description.abstract Objective: The purpose of this study was to investigate the use of a 975nm diode laser for skin tightening. Background data: The photothermal effect of laser irradiation on the hypodermis causes retraction of superficial and deep skin layers by the heating of fibrous septa. New devices have been developed for repairing deformities in the cervicofacial region associated with aging and skin laxity. Materials and methods: This retrospective, cross-sectional study included the medical records of 17 patients who had undergone photothermal laser therapy to correct deformities in the cervicofacial region between June 2013 and February 2015. An energy dose of 3kJ per 100cm(2) skin area was used as a safety parameter to calculate the optimal cumulative energy for the treated areas. Four cervicofacial lines were measured preoperatively (baseline), immediately after treatment, and 3 months post-treatment with a caliper. Measurements were compared using the Wilcoxon test at a significance level of 0.05 (p<0.05). Results: A significant skin tightening was observed in all patients 3 months after the procedure. Mean length reductions found in the cervicofacial lines L1, L2, L3, and L4 at the 3-month follow-up were 0.9, 1.18, 1.32, and 1.27cm, respectively. Conclusions: The use of a 975nm diode laser resulted in skin tightening. en
