The larynx is the organ of voice located in the neck, connecting the pharynx to the respiratory tract. The pharynx serves as a passage for both the air and food pathways, branching into the respiratory tract beginning with the larynx and the digestive tract starting with the esophagus. The primary function of the larynx is to protect the respiratory pathway; it closes off to prevent food and foreign materials from entering the lungs, and coughing may occur in an attempt to expel these foreign substances. The larynx also plays a role in controlling ventilation and sound production.
Throat dryness, or dry throat, refers to the dryness of the mucous membranes lining the larynx and is common among those who rely on their voice for work, such as teachers or singers.
When is throat dryness serious? Throat dryness is often associated with minor medical conditions and can usually be treated simply. However, it is important for patients to consult their doctor if hoarseness or throat dryness persists for more than two weeks.
In cases of difficulty swallowing, breathing challenges, wheezing while breathing, fever, coughing up blood, the appearance of a rash, chest pain, or a lump in the neck, immediate medical attention should be sought.
