Abstract
The larynx is a complex organ that houses some of the most intricate structures of the human body. Owing to its delicate nature, the larynx is affected by different medications to varying degrees. Many of these effects manifest in subjective complaints in one's voice or swallow. This review article invokes the present available literature to describe the effects different medical agents have on the functionality of the laryngeal structures. Multiple available studies explore the effects of inhaled corticosteroids on the larynx. While laryngeal candidiasis is a well known complication of chronic steroid use, other rarer fungal infections have also demonstrated themselves as risks. Among anesthetics, the literature suggests that sevoflurane in standard and high doses does not appear to significantly reduce the risk of laryngospasm. The use of topical and intravenous lidocaine appear to have conflicting evidence regarding their use in laryngospasm prevention, whereas postoperative sore throat, hoarseness, and cough may be prevented with preinduction nebulization of ketamine and magnesium sulfate or budesonide. Further study is warranted to explore the effects that these and other classes of agents, such as antibiotics, have on the structure and function of the larynx.
