Pharyngitis is primarily a nonspecific inflammation of the throat, which can be divided into acute pharyngitis and chronic pharyngitis. Acute pharyngitis is mainly caused by bacterial infections affecting the mucous membrane and submucosal tissues of the throat, leading to symptoms such as dry throat, burning sensation, sore throat, and pain when swallowing. The main pathogens involved are often streptococcus and staphylococcus, among others. Patients with chronic pharyngitis mainly experience a foreign body sensation in the throat, along with dryness and itchiness. In contrast, patients with vocal cord polyps, which mainly differ from pharyngitis, exhibit hoarseness. Typically, pharyngitis patients do not exhibit obvious hoarseness. Differentiation between the two can be achieved through an examination with a laryngoscope, which can determine the presence of obvious polyp growth on the vocal cords, thereby distinguishing between vocal cord polyps and pharyngitis.
