Bowing of the vocal folds can result from aging, atrophy or idiopathic causes, such as an injudicious vocal cord surgery. Bowing results in dysphonia due to inadequate approximation of the vocal folds. A number of treatments have been proposed for this condition. Intracordal injection of biological materials including liquid silicon and Teflon and various types of thyroplasty have been utilized...

Porokeratosis, a keratinization and fibroblast cutaneous disorder, is a progressive disease with limited treatment options. We describe a case of linear porokeratosis that responded favorably to a series of 585 nm pulsed dye laser treatments. In addition to its vascular specificity, the pulsed dye laser presumably produces a direct effect on collagen, as well as an indirect effect on histamine ...

BACKGROUND Several case reports document successful treatment of sebaceous hyperplasia with the pulsed-dye laser. Moreover, noninvasive real-time confocal laser scanning microscopy elucidates the vascular nature of these lesions and their pathophysiologic response to treatment mediated by vessel coagulation. METHODS Ten patients with 29 lesions of sebaceous hyperplasia were treated with 3 sta...

OBJECTIVE To assess the safety and efficacy of the long-pulsed pulsed dye laser (LP PDL) (595 nm) with photodynamic therapy (PDT) for treatment of actinic keratoses (AKs). DESIGN Prospective, controlled study with 10-day and 2-, 4-,6-, and 8-month follow-ups. SETTING Clinical research center. PATIENTS Volunteer sample of 41 patients (age range, 35-91 years; skin types I-III) with AKs. INT...

This paper describes the passive Qswitch, based on polymer and organic dye BDN, of a pulsed Nd:YAG laser. Pulses of 27ns duration and peak power of 1.7MW for initial transmission of Q-switch 18.4% 0 T = have been obtained. We have obtained Q-switching efficiency of 77% for train of pulses of 31 and 76.2% 0 T = at the pump energy of 98J. We have also obtained the dependency of laser pulse charac...

IMPORTANCE Although facial vascular malformations are often treated by facial plastic surgeons, no reliable validated assessment tool exists for surgeons to assess results. OBJECTIVES To use our assessment tool to analyze results from pulsed-dye laser therapy used for pediatric facial vascular malformations, and to determine interrater reliability of our assessment tool in a standard clinical...

BACKGROUND Purpura-free elimination of telangiectases with a single pass of a pulsed dye laser with a large spot has proved difficult. OBJECTIVE The purpose of this report was to define parameters that achieve single-pass purpura-free telangiectasia reduction. MATERIALS Thirty patients between the ages of 23 and 78 years were treated with a pulsed dye laser with a 10-mm spot and fluences ra...
