Laryngitis and pharyngitis are common diseases in otolaryngology, occurring in different parts of the throat. Laryngitis primarily affects the mucous membrane and vocal cords of the larynx, causing congestion and swelling of the surface mucosa. The most typical symptom in patients is hoarseness, and some may experience coughing and phlegm among other related symptoms. Meanwhile, patients with chronic pharyngitis primarily present symptoms like a foreign body sensation in the throat, dryness, soreness, and a burning sensation.

When these symptoms appear, an initial diagnostic step can be through a digital nasopharyngoscope to confirm the patient's condition, followed by symptomatic treatment with throat-soothing medications under a physician’s guidance. In daily life, it is also important to protect the voice by avoiding loud talking or shouting, and maintaining a light diet, which helps protect the mucous membranes of the throat from inflammation and prevent the aforementioned symptoms.
