This book synthesizes the current literature on the effects of vaping on voice and discusses the pathophysiology of voice symptoms in affected patients. The detrimental impact of e-cigarette smoking on various systems in the body, including those that affect voice production, is also reviewed. E-cigarette smoking has been shown to impair pulmonary function, which jeopardizes the power source for voice production. It has been associated with an increase in sinonasal and oral symptoms, thus altering voice resonance and quality. Vaping has been linked to reflux disease and esophagitis, putting the defenseless lining of the larynx and pharynx at risk of injury by the gastroduodenal refluxate. Providing insights on the adverse effects of e-cigarette smoking on the phonatory apparatus is of paramount importance, particularly in professional voice users who rely on their voice to make a living. E-Cigarette Smoking, Voice, and Health is addressed to all medical doctors, interns, and health care providers, and in particular to otolaryngologists, laryngologists, speech-language pathologists, and voice therapists.
