Objective The objective of this work was to gather an international consensus group to propose a global definition and diagnostic approach of laryngopharyngeal reflux (LPR) to guide primary care and specialist physicians in the management of LPR. Methods Forty‐eight international experts (otolaryngologists, gastroenterologists, surgeons, and physi...

Session Description: This panel presentation comprehensively reviews evaluation and management of vocal fold leukoplakia. Updated from prior years, this iteration will explore management strategies through focus on a case-based approach. Though white vocal fold lesions are common, management remains challenging—doing too little may allow precancero...

Objective This state-of-the-art article reviews the epidemiology, diagnosis, and management of vocal fold leukoplakia, with focus on recent advances. It focuses on the clinical challenges that otolaryngologists face balancing both oncological efficacy and functional outcomes in leukoplakia and presents the current philosophies and techniques to con...

This miniseminar comprehensively reviews the evaluation and management of laryngeal leukoplakia. Although “white vocal fold lesions” are common, management remains challenging—doing “too little” may allow precancerous lesions to progress, while doing “too much” may create unnecessary dysphonia. Using cases, panel discussion, and the encompassing of...

Introduction: Pre-cancerous lesions of the larynx are common and can progress to invasive carcinoma. Such lesions, usually of the true vocal folds, may then require surgical resection or irradiation with subsequent morbidity of treatment. There is currently no gold standard treatment of glottal dysplasia. Instead, one adopts “watchful waiting” unti...

Evolving photoangiolytic laser techniques for treating vocal fold lesions motivated the development of a model for research and surgical training. The chick chorioallantoic membrane (CAM), which is composed of a microvasculature suspended within the egg albumen, simulates the vocal fold microcirculation within the superficial lamina propria (SLP)....

Angiolytic lasers have been shown to be an effective treatment strategy for laryngeal papillomatosis. These lasers precisely target hemoglobin within the microcirculation of papillary lesions. We have previously demonstrated the advantages of the fiber-based pulsed 532-nm potassium-titanyl-phosphate (KTP) laser in an office setting (with local anes...

Objectives: Selective vascular ablation (photoangiolysis) using pulsed lasers that target hemoglobin is an effective treatment strategy for many vocal fold lesions. However, vessel rupture with extravasation of blood reduces selectivity for vessels, which is frequently observed with the 0.45-ms, 585-nm pulsed dye laser. Previous studies have shown...

Objectives: The carbon dioxide (CO2) laser is the premier dissecting instrument for hemostatic cutting and ablation during endolaryngeal surgery. However, microlaryngeal tangential dissection and office-based photoablation have been limited by the lack of a fiber-based delivery system. To address this limitation, a new laser was designed, which is...

The objectives were to assess the clinical performance and accuracy of a prototype fiberoptic transnasal laryngeal endoscope with an auxiliary optical system that allows images to be spatially calibrated. A novel fiberoptic endoscope was developed that projects green laser beams across the field of view from a separate optical channel. According to...

Objectives Treatment of glottal papillomatosis and dysplasia was mirror-guided and done in surgeons' offices in the 19th century. It migrated to the operating room in the 20th century to accommodate direct laryngoscopic surgery, which required assistants to administer anesthesia and procedural support. The primary treatment goals, which are disease...

Varices and ectasias in singers are typically the result of phonotraumatic shearing stresses and/or collision forces on the microcirculation within the superficial lamina propria. These lesions can be debilitating in performing vocalists because of the effect of recurrent hemorrhage and/or as a contributing factor to the morbidity of other mass les...
