Recent methods for stabilizing systems like, e.g., loss-modulated CO2 lasers, involve inducing controlled monostability via slow parameter modulations. However, such stabilization methods presuppose detailed knowledge of the structure and size of basins of attraction. In this Brief Report, we numerically investigate basin size evolution when parameters are varied between dissipative and conserv...

Lasers have become a popular tool in veterinary practice, particularly the carbon dioxide (CO2) laser. In humans, the CO2 laser is used most commonly in oral and maxillofacial soft tissue surgery due to its favorable interactions with oral soft tissues. Other types of lasers are better suited for use on hard tissues such as enamel and dentin. This article reviews the history of laser use, physi...

Winkler's disease otherwise known as chondrodermatitis nodularis chronica helices (CNHC) is characterized by a painful persistent erythematous nodule, mostly located at the rim of helix of pinna. Occurs mostly in men over 40 years of age. Standard therapy is by local excision or carbon dioxide laser vaporization. Recurrence is frequent.

peri-implantitis is a state defined as an inflammatory reaction around osseointegrated implants, leading to progressive loss of supporting bone. various treatment methods are suggested in the treatment of peri-implantitis and clinicians have to choose a method over a large number of treatment protocols. lasers have shown promising therapeutic effect in treatment of peri-implantitis. however, so...

Though the primary role of lasers in urology has always been in the treatment of urolithiasis, there are several other indications for their use. There are many different types of lasers currently available, each with unique properties conducive to treating certain disorders. As such, it is critical that today's urologist understands each laser's characteristics in order to optimize patient sel...

Rhinophyma is a severe late complication of rosacea, which is characterized by progressive hyperplasia of sebaceous glands and connective tissue involving the lower two-thirds of the nose. It can be an emotionally devastating disorder, and serve as a medium for occult cancers and other health problems. Many surgical treatments have been advocated, as well as dermabrasion and laser therapy. In l...

BACKGROUND While skin resurfacing using pulsed carbon dioxide lasers appears to have a skin-tightening effect clinically, the debate continues over its actual effects on dermal collagen. OBJECTIVES To provide quantitative measures of skin elasticity changes associated with pulsed carbon dioxide laser skin resurfacing and to introduce to the facial plastic surgery community the Cutometer SEM 5...

A new era in dermatological cosmetology, especially in the field of nonsurgical skin rejuvenation, started with ablative resurfacing, at first by carbon dioxide laser and later by Er:YAG or their combination. Although ablative lasers result in major improvements in photodamaged skin, the related postoperative recovery time and side effects are currently unacceptable for most patients. During th...

The carbon dioxide (CO2) laser was first introduced in 1964 by Patel and has been extensively used in the next two decades as an incision tool in increasingly wide areas, such as neurosurgery, dermatology and plastic surgery, otorhinolaryngology, ophthalmology, gynecology, and general surgery. In 1984, its reliability resulted in its approval by the U.S. Food and Drug Administration, and thus, ...
