Rhinitis belongs to a heterogeneous group of nasal disorders manifested by
one or more of the following symptoms: sneezing, rhinorrhea, nasal itching,
and nasal congestion (1). The inflammation of the nasal mucosa and intra-
nasal structures are caused frequently by allergic and nonallergic rhinitis. In
a significant proportion of the population, allergic rhinitis is the most frequent
cause of chronic rhinitis (1-3). Nonallergic rhinitis occurs in 30-50% of
patients with rhinitis (1). Patients with allergic and nonallergic rhinitis share
common symptoms such as nasal congestion, rhinorrhea, sneezing, and post-
nasal drip (1,2,4).
