Laser-assisted liposuction for facial and body contouring and tissue tightening: a 2-year experience with 75 consecutive patients

Seminars in Cutaneous Medicine and Surgery
Gordon H Sasaki, Ana Tevez

Abstract

Internal liposuction remains the standard and most reliable method to remove fat and contour the face and body. The recent introduction (2006 FDA clearance) of a higher and more controlled energized internal laser system is purported to increase tissue contraction and damage unwanted fat deposits through dual 1064 nm/1320-nm wavelengths that are initially used at a deep level of subcutaneous fat, and subsequently at a shallow level beneath the dermis along with liposuction. Using classical principles of selective photothermolysis, the sequential exposure of these wavelengths on target tissue chromophores results in selective thermo-lipolysis and thermo-denaturation of collagen fibers (H(2)O) within the septal architecture and lower reticular dermis for enhanced skin retraction (accommodation) and contraction. This article reviews this innovative laser system, discusses the latest clinical protocol changes, tabulates the measurements of time and energy during each phase of treatment and temperature endpoints, and correlates the histologic findings to energy deposition. The collected objective data are used to improve on the safety and efficacy treatment profiles at 11 sites in 75 consecutive patients. Further clinical studies an...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
