Abstract:
Olfactory dysfunction (OD) is one of the cardinal symptoms of chronic rhinosinusitis (CRS), and its prevalence ranges from 60% to 80% in patients with CRS. It is much more common in CRS with nasal polyposis patients compared to CRS without nasal polyposis. Decreased olfactory function is associated with significant decreases in patient-reported quality of life (QOL), and notably, depression and the enjoyment of food. Objective measures can help detail the degree of OD, whereas subjective measures can help to determine in the impact on patient. There is variable treatment response to OD with both medical and surgical therapies.

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.
