OBJECTIVE. T
O study cutaneous microcirculation in patients undergoing hardware high-energy cosmetic procedures and to assess the risks of trophic abnormalities in lateral fatty-cutaneous flaps of the face and neck in rejuvenation surgeries using laser flowmetry.
MATERIAL AND METHODS
The authors examined 220 patients aged 25-65 years (42.7±8.3 years) using laser flowmetry. The control group consisted of 100 patients without previous hardware cosmetic procedures. The study group included 120 female patients who underwent one of the most common procedures: ultrasonic SMAS-lifting (n=42), micro-needle RF-lifting (n=51), laser removal of skin capillaries on the face and neck (n=27). Microcirculation parameters in lateral fatty-cutaneous flaps of the face and neck were analyzed. The authors performed wavelet transformation of spectral characteristics of blood flow oscillatory activity to establish the role of various regulatory mechanisms. Tissue oxidative metabolism processes were additionally estimated.
RESULTS
There was a negative influence of high-energy hardware cosmetic techniques on cutaneous microcirculation of the face and neck. According to laser flowmetry, such techniques significantly reduced participation of endothelial factor of microcirculatory flow regulation in maintenance of normal functioning of microcirculatory channel, caused pathological activation of neurogenic and myogenic factors, as well as impaired oxidative metabolism in tissues. Certainly, compensatory capabilities of microvascular system are sufficient for adequate functioning of soft tissues in patients not planning surgical intervention in the future. However, such changes will contribute to various postoperative trophic disorders in detached skin and fatty flaps of the face and neck.
CONCLUSION
In postoperative period, negative impact of previous high-energy hardware cosmetic procedures can be so significant that inevitably leads to trophic abnormalities in detached lateral adipo-cutaneous flaps of the face and neck. In this regard, surgeons should preoperatively analyze cutaneous microcirculatory of the face and neck in such a patient to take timely preventive measures and correct surgical intervention.
