FACIAL REJUVENATION USING MULTIPLE LASER MODALITIES

Fig. 3. Clinical improvement after multi-modal sequential laser rejuvenation of the face. Significant improvements were noted in all clinical parameters at both short- and long-term follow-up periods ( A – D : P < 0.01). No significant difference was detected between short- and long- term follow-ups, indicating sustained improvements over time. N ¼ 50, data represented as mean SD.

time was quantified according to the number of days before no further specialized wound care was required (any application of dressings, creams, ointments etc). A patient satisfaction survey was conducted to assess patient perceived improvement, lifestyle disruption, pain or discomfort, and overall satisfaction (Appendix 2). Statistical Analysis Numerical data were tabulated and displayed in graphical format using GraphPad Prism. Statistical analysis was performed utilizing one-way ANOVA to compare the means between multiple groups (baseline, short-term, and long-term follow-up groups). Gaussian distribution of the data set were confirmed utilizing the D’Agostino–Pearson omnibus normality test.

using a focused spot size and varying distances to control the amount of ablation to an approximate depth of 25–50 m m per pulse. Finally, a full face and neck treatment with deep fractioned CO 2 laser (Fraxel Re:Pair) was performed. The peri-orbital region and eyelids were treated with 20–30 J/cm 2 and 30–35% density; the face was treated with 30–50mJ and 50–55% density; and 20–30mJ was used to treat the neck in tapering fashion with 30% density at the submental region, and then 25%, 20%, and 15% proceeding inferiorly. Evaluation of Primary Outcomes Standardized clinical photographs were obtained of each patient prior to treatment and follow up photography post-treatment was conducted on a regular basis. Both short- (less than 3 months) and long-term (up to 1.5 years) analysiswas performed. Analysiswas conducted by twonon- treating blinded physicians. Clinical criteriawas scored on a 0–4 scale (Appendix 1) and included evaluation of dyspig- mentation, telangiectasia, and skin texture. Rhytides were evaluated with the Fitzpatrick Wrinkle Scale (Appendix 1). Overall percentage improvement was also rated. Healing

RESULTS Baseline Patient Characteristics

Prior to treatment, patients were assessed for baseline dyspigmentation, rhytides, telangiectasia, and skin texture (Fig. 1). These data reveal that on average,
