Tumescent liposuction is an exceptionally safe method of liposuction under local anesthesia that eliminates the necessity of general anesthesia and blood transfusions. Tumescent liposuction is safer than liposuction under general anesthesia and results in fewer complications.

The extended theory of selective photothermolysis enables the laser surgeon to target and destroy hair follicles, thereby leading to hair removal. Today, laser hair removal (LHR) is the most commonly requested cosmetic procedure in the world and is routinely performed by dermatologists, other physicians, and non-physician personnel with variable efficacy. The ideal candidate for LHR is fair skinned with dark terminal hair; however, LHR can today be successfully performed in all skin types. Knowledge of hair follicle anatomy and physiology, proper patient selection and preoperative preparation, principles of laser safety, familiarity with the various laser/light devices, and a thorough understanding of laser-tissue interactions are vital to optimizing treatment efficacy while minimizing complications and side effects.

Fractional photothermolysis has been reported in the literature to improve both the pigmentary and textural changes associated with photoaging. The objective of the study was to review the literature of non-ablative fractional laser (NAFL) and ablative fractional laser (AFL) resurfacing for the treatment of photoaging. This is a review of the Medline literature evaluating NAFL and AFL for photoaging. Review of the literature supports the use of NAFL and AFL as safe and effective treatments for photoaging. It is likely that the controlled, limited dermal heating of fractional resurfacing initiates a cascade of events in which normalization of the collagenesis/collagenolysis cycle occurs. The advent of fractionated resurfacing for the treatment of photoaging is a significant advance over ablative laser resurfacing treatments, which were complicated by prolonged erythema, delayed onset hypopigmentation, and scarring.

There are an increasing number and variety of dermatologic surgical procedures performed safely in the office setting. This evidence-based guideline addresses important clinical questions that arise regarding the use and safety of local anesthesia for dermatologic office-based procedures. In addition to recommendations for dermatologists, this guideline also takes into account patient preferences while optimizing their safety and quality of care. The clinical recommendations presented here are based on the best evidence available as well as expert opinion.

Basal-cell carcinoma with perineural invasion is a rare occurrence. Ten patients with this phenomenon are described. Review of our cases and cases in the literature indicates that perineural spread of basal-cell carcinoma is most common in men with recurrent tumors. The horizontally cut frozen sections that are utilized in Mohs surgery maximize the chances of discovering basal-cell carcinoma with undiagnosed involvement.
