AbstractEnergy-based facelifting techniques are a relatively new genre of surgery. In this approach, the energy-based device—whether laser, radiofrequency plasma, or ultrasound—can be used in the superficial plane to elevate skin flaps before performing more traditional facelift techniques involving the superficial musculoaponeurotic system (SMAS) or platysma. The initial reports of utilizing fiber lasers as surgical tools date back to approximately 2007 and initial lipolasers were used to elevate facial skin flaps. The other energy-based devices were also tested. The author has probably the largest series of energy-based facial rejuvenation procedures, having performed over 3,000 of these procedures. The advantages of laser-assisted rhytidectomy include hemostasis, facilitated dissection in areas hard to elevate conventionally such as nasolabial folds or distal neck and the remodeling and tightening of tissue that results from the activation of the wound healing cascade of neocollagenesis and wound contraction. The author currently has a preference for energy device used during rhytidectomy and it is a high frequency ultrasound energy delivered by a five-ring 2.9- and 3.7-mm probe. The use of the ultrasound dissector in both superficial and deep procedures is highlighted in this article with emphasis on its use for deep cervicoplasty and subplatysmal procedures as well as sub-SMAS elevations of the facial deep plane.

The diagnosis of cutaneous T-cell lymphomas (CTCL) is frequently delayed by a median of three years and requires the clinical evaluation of an experienced dermatologist and a confirmatory skin biopsy. Dermoscopy and high-frequency ultrasound (HFUS) represent two non-invasive diagnostic tools. While dermoscopy is inexpensive and widely used for the diagnosis of melanoma and non-melanoma skin cancers, HFUS of skin lymphomas represents a novel diagnostic approach that is not yet implemented in the routine dermatologic practice. The aim of our study was to prospectively assess skin lesions of patients with either CTCL patches or plaques with dermoscopy and HFUS and to compare the findings with atopic dermatitis (AD) and psoriasis. Thirteen patients with an established diagnosis of CTCL, psoriasis, or AD were studied: Dermoscopy features including spermatozoa-like structures and the presence of white scales could assist in differentiating between early-stage CTCL and AD. HFUS measurements of the skin thickness indicated increased epidermal-, thickness in CTCL, and psoriasis compared with AD. Our results support the use of dermoscopy as a useful tool to diagnose CTCL. HFUS could augment the dermatologic assessment, but further studies will be needed to define standardized parameters.
