Office Pulsed Dye Laser Treatment for Benign Laryngeal Vascular Polyps: A Preliminary Study

Abstract

In-office use of the PDL for treatment of vascular polyps may be a safe alternative to phonomicrosurgery. Small polyps seem to show a better response.

“…24 A previous study reported successful in-office ablation of hemorrhagic vocal polyps using the pulsed-dye laser. 6 The sizes of vocal lesions regressed significantly in 78% of the study population after 1 to 2 courses of laser treatments; 14% of the patients required surgical polypectomy. Likewise, office-based KTP laser treatment also resulted in significant lesion reduction, usually within 2 postoperative months.…”

“…To ensure complete removal of the vocal polyp during a single procedure, we included only small polyps with a long-axis diameter less than 30% of the vocal fold length visualized on image-processing software (Image J, version 1.44; National Institutes of Health). 6 We excluded nonhemorrhagic and/or wide-based polyps. Among the recruited patients, 20 underwent KTP laser-assisted polypectomy, whereas the other 16 were treated with the KTP laser without endoscopic removal of the polyps.…”

“…5 Previous studies proposed the potential application of the potassium titanyl phosphate (KTP) or pulsed-dye laser for the treatment of various vascular lesions of the vocal fold, for example, varicosity, ectasia, and hemorrhagic polyp. [6][7][8] The most significant advantage of KTP and pulsed-dye lasers is the proximity between the 532-nm and 585-nm wavelengths, respectively, of each laser and the absorbance peak of oxyhemoglobin, which results in selective angiolysis and photocoagulation of the vascular lesions with minimal thermal injury to the lamina propria of the vocal fold.…”

Advances in office‐based diagnosis and treatment in laryngology

“…In‐office laser treatment is indicated for a variety of epithelial lesions of the larynx, including papilloma, granuloma, leukoplakia, dysplasia, Reinke's edema, and vocal fold polyps 46, 48, 51, 52. It has also been used in selected other lesions, such as vascular ectasias and stenosis 47, 48, 53.…”

In‐office procedures for the treatment of benign vocal fold lesions in the awake patient: A contemporary review

“…Due to delayed lesion regression, the final result should only be expected 4 weeks after the procedure . Smaller polyps tend to respond well to single‐stage in‐office laser procedure, whereas larger polyps may require repeat procedures . The reported complete resolution rates for in‐office KTP and PDL procedures are 85% to 100% and 38% to 100%, respectively.…”
