Lateral pharyngitis is an inflammation of the mucous membrane of the posterior wall of the pharynx at the level from the lingual to the laryngeal part (at the level of the cricoid cartilage arch). Pharyngolaryngitis is bilateral. Localized in the post-pharyngeal fascia, it is also capable of spreading to the peripharyngeal tissue. As a rule, the disease occurs as a result of an acute respiratory disease affecting the oral cavity and pharynx.
On the back wall of the pharynx, located above the level of the tonsil, a swelling is detected, which quickly takes the form of a granular tubercle. The patient notes discomfort associated with swallowing and a dry cough. Laryngeal pharyngitis is accompanied by saliva flowing down the back wall of the pharynx. Symptoms of rhinitis, conjunctivitis or laryngitis are often observed. The severity of symptoms varies. Severe forms of the disease are accompanied by headache, fever, and weakness. Lymphadenopathy occurs.
