Abstract:
Laryngopharyngeal reflux is a new term given to gastroesophageal reflux leading to atypical symptoms in the upper aerodigestive tract. The manifestations of laryngopharyngeal reflux are varied and include chronic hoarseness, globus pharyngeus, sore throat, chronic cough, asthma, paroxysmal laryngospasm, and other less common symptoms. Making the diagnosis requires accurate history taking and can be confirmed by fiberoptic examination of the pharynx and larynx, as well as by ambulatory esophageal and pharyngeal pH monitoring. Stepwise treatment regimens are very effective in treating this condition, which exacerbates or imitates many seemingly unrelated disorders.

Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...
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,...
