EVALUATION OF OLFACTORY LOSS IN PATIENTS WITH ALLERGIC RHINITIS
Sonya Ahmed EI-Gaaly;
Abstract
Allergic rhinitis is a common medical problem, characterized by profuse rhinorrhea, paroxysms of sneezing, nasal congestion and itching.
Allergic rhinitis is a hypersensitivity reaction due to exposure to a certain allergen, lgE causing degranulation of the mast cells, eosionophils, and neutrophils, leading to mediators release as histamine, leukotriens prostaglandin, plateiet activating factor and kinins. These mediators cause increase in the vascular permeability, and glandular secretion together with stimulation of afferent nerve resulting in itching and sneezing.
The complaints of olfactory loss are not uncommon to be presented. Although not a life threatening condition, chronic impairment can significantly affect an individuals sense of well
being.
Hence there is a high prevalence of olfactory loss in skin test
positive allergic rhinitis patients, excluding the presence of polypi
t and sinusitis, which suggests that the allergic processes may have affected olfactory function.
In this work, pathogenesis, clinical picture and diagnosis of allergic rhinitis were reviewed.
