Abstract:
Chronic laryngeal symptoms are often attributed to gastroesophageal reflux disease based on nonspecific testing by laryngoscopy resulting in overdiagnosis of this condition. Identifying optimal means by which we can diagnose reflux in patients with chronic laryngeal symptoms is an unmet clinical area. One such technique might be measurement of oropharyngeal acid exposure employing a novel pH monitoring device. We outline the strengths and limitations of this new technology relative to the observational cohort study by Yadlapti et al. published in this issue of the Journal.

Larynx
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...
Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
