OBJECTIVE To determine the effect of carbon dioxide laser microsurgery in the treatment of intractable chronic myringitis (CM). DESIGN Retrospective 10-year case note review. SETTING Tertiary referral hospital. PATIENTS We reviewed retrospective case notes for 30 treated ears in 29 consecutive patients with CM (ie, loss of the tympanic membrane for longer than 1 month, refractory to conse...

The high-energy, short-pulse carbon dioxide (CO2) laser became one of the mainstays of cosmetic resurfacing after its introduction in the late 1980s. Its popularity is related to its unparalleled ability to treat deep facial rhytides, furrows, fine lines, scars, photodamage, and textural irregularities. Although these findings are impressive, it also came with well-documented risks such as dysp...

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...

In the new global economy, consumption has become a central issue for many fields of industries. This project work studied on the effectiveness of pulse duration of supercritical carbon dioxide (SCCO2) in machining performance in terms of cutting temperature, cutting force and surface roughness in turning AISI 1045 medium carbon steel by uncoated cemented carbide insert. Pulse mode reduces the ...

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.

OBJECTIVES The development of the scanning system AcuBlade has considerably enhanced carbon dioxide laser energy delivery, improving cutting and ablation modes. The scanning system can be applied with the 2 available high-powered pulsed waves, SuperPulse and UltraPulse. This study was conducted to determine whether there are any differences in phonosurgery between the SuperPulse and UltraPulse ...

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 ...
