Abstract
BACKGROUND Laser resurfacing is used to minimize wrinkles, solar scars and sequelae of acne. OBJECTIVE Purpose of the systematic review was to compare resurfacing outcomes of CO2 laser and erbium: yttrium aluminium garnet (erb:YAG) laser therapies. MATERIALS AND METHODS Medline, Cochrane Library, EMBASE and Google Scholar databases were searched until 9 April 2015 using the following terms: laser, carbon dioxide/CO2, facial wrinkles, rhytides and erbium-doped yttrium aluminium garnet/erbium:YAG/Er:YAG. Two-armed controlled split faced studies that compared CO2 laser and erbium:YAG laser in patients with mild-to-moderate facial wrinkles or rhytides were included. RESULTS The pooled data in this study and findings of other studies support the greater efficacy with the CO2 laser in improving facial wrinkles, but the erb:YAG laser was associated with a better complication profile compared with the CO2 laser. Except one case of hypopigmentation, other complications (i.e., erythema, hyperpigmentation and crusting) and their rates were reported by studies examining both lasers. CONCLUSION In general, the CO2 laser appeared to be more efficacious then the erb:YAG laser in treating facial wrinkles. Both lasers treatments were well tolerated.

Abstract
BACKGROUND Various scalpel surgeries have been described to correct earlobe clefts secondary to wearing earrings. Limitations include notching, scarring, and technical difficulty operating on a small surface. OBJECTIVE To report the development of a more rapid and less complicated method of using a laser to partially close an incomplete earlobe cleft. METHODS An Er:YAG laser was used to deepithelialize the anterior and posterior lower border of an incomplete earlobe cleft followed by suturing the anterior and posterior defect. RESULTS An excellent result was obtained which left the pierced hole in its original location. CONCLUSION This technique is simple to perform and has definite advantages over other methods currently in use.
