The Role of Nasal Cytology in the Management of Inferior Turbinate Hypertrophy

Abstract

Inferior turbinate hypertrophy (ITH) is the main cause of nasal obstruction symptom. This study aimed at investigating whether a particular cellular pattern could be a predictive factor for failure of medical treatment for ITH in patients with rhinitis. Globally, 258 patients with chronic nasal obstruction due to ITH were evaluated by: visual analogue scale assessment of symptoms, skin prick tests, fiber-endoscopy, active anterior rhinomanometry, and nasal cytology. All patients were treated with drugs for 3 months and then re-evaluated. The symptom improvement depended on the different cellular pattern. There was improvement in: 54 (51.4%) patients with allergic rhinitis, 72 (69.2%) with non-allergic rhinitis with neutrophils (NARNE), 15 (42.8%) with non-allergic rhinitis with eosinophils (NARES), and 9 (64.3%) with non-allergic rhinitis with mast cells/non-allergic rhinitis with eosinophils and mast cells (NARMA/NARESMA). The non-responders (108; 41.9%) were therefore directed towards surgical treatment. Both patients with allergic rhinitis and patients affected by NARES had a higher failure rate to medical treatment compared with NARMA and NARESMA groups (p<0.01). In conclusion, elevated number of eosinophils, in the nasal secretion of both allergic (allergic rhinitis) and non-allergic (NARES) patients with ITH, can be associated to a higher medical treatment failure rate.
