Chronic laryngitis
Pages 12

INTRODUCTION Chronic laryngitis is chronic inflammation of the laryngeal structures, most commonly affecting the laryngeal mucosa and to a certain extent the submucosa. The chronic inflammatory process can be due either to infectious or non-infectious causes, with a broad spectrum of aetiologies which may act singly or in combination. The chronic changes in the larynx can result in many laryngopharyngeal symptoms but the principal effect of the condition is a persistent and fluctuating change in voice and subsequent impact on the quality of life of the patient. The high prevalence of the main aetiological factors associated with chronic laryngitis, namely smoking and voice abuse, and the debated influence of reflux disease, whether it be laryngo-pharyngeal reflux or gastro-oesophageal reflux, results in the management of this condition being challenging in relation to both diagnosis and efficacy of treatment.
