Occupational aspects of irritable larynx syndrome

Abstract

Purpose of review 

The aim of this article is to provide an update on occupational aspects of irritable larynx syndrome (ILS).

Recent findings 

It is being increasingly recognized that ILS is common amongst certain occupations. This is particularly true of occupations that require frequent voice use such as teachers; where there is exposure to workplace irritants such as World Trade Center responders; or mechanical factors that cause laryngeal dysfunction such as elite athletes. Work associated ILS impacts on quality of life but responds to speech and language therapy focusing on education, vocal hygiene, and laryngeal exercises that reduce cough and treat acute laryngeal obstruction episodes.

Summary 

ILS may be caused or exacerbated by many occupational exposures, causes significant symptoms, and impacts on quality of life. It is potentially treatable and may well be preventable. More research in this important area is required.
