introduction: definitive treatment of oral leukoplakia is very important because of its recurrences and malignant transformation depending on the location, clinical feature,degree of dysplasia and etiological factors. there are different kinds of treatment for this lesion, but using high power laser has some advantages like less pain, swelling, prevention of metastasis, edema, less bleeding (dr...

Eighteen dogs were used to compare histopathological findings following excision of the soft palate using either a bipolar sealing device or a carbon dioxide laser. Histopathological comparisons were done at 48 and 96 hours after soft palate resection. Mean depths of tissue injury at 96 hours were 3.5 and 3.33 mm for bipolar sealing device and carbon dioxide laser, respectively. Control of hemo...

OBJECTIVES To evaluate the effectiveness of the carbon dioxide laser for treatment of facial acne scarring and to determine if certain regions of the face would respond more favorably to carbon dioxide laser resurfacing than other areas of the face. METHODS Twenty-five patients with facial acne scarring were treated with the carbon dioxide laser with the flash-scanning attachment. Physician a...

The treatment of atrophoderma vermiculatum is challenging. A 7-year-old girl had a unilateral atrophic skin lesion on her right cheek, which was diagnosed as unilateral atrophoderma vermiculata. She was treated by carbon dioxide and 595 nm pulsed dye laser and carbon dioxide laser. This resulted in prevention of the lesional progression with favorable cosmetic appearance of the skin.

OBJECTIVE To determine the efficacy of various eye protection measures during carbon dioxide laser laryngoscopy. DESIGN A standard medical mannequin was equipped with indicator paper over the eyes and subjected to multiple passes of direct carbon dioxide laser beam contact at 400-mm focal length with powers ranging from 2.5 to 4.0 W during simulated laser microlaryngoscopy. Several different ...

A 2-month-old infant underwent excision of granulomata of vocal cords with a carbon dioxide laser. High frequency jet ventilation was given through a surgical metal suction tube during the operation. The anaesthetic technique for the infant and the problems of the use of carbon dioxide laser in laryngeal surgery are discussed.

OBJECTIVE To determine whether prior silicone injection increases the risks associated with carbon dioxide laser resurfacing. DESIGN Laboratory determination of the effect of laser energy on liquid silicone; histologic evaluation of silicone-injected skin after lasing; and histologic demonstration of silicone deposits in all layers of dermis years after injection of silicone as filler fluid. ...

Digital mucous cysts are common tumours of the distal interphalangeal joint, causing pain, cosmetic disfigurement and nail deformities. This study describes six patients suffering from digital mucous cysts, some of which recurred after surgery. Carbon dioxide laser vaporization was performed under local anaesthesia, resulting in complete remission in four out of six patients. In two patients, t...
