A study of allergic factor in nasal polyp patients.

Various investigations for allergy were carried out on 57 nasal polyp patients. The majority of them (96.5%) showed positive responses to at least one of the methods used. The results suggest that allergy is a constant feature in the nasal polyp patients but that further investigation is needed before we can state that allergic manifestation contributes to polyp formation. It was also found in this study that 90% of the patients had definite pathological changes on their sinus x-rays. Sinus disease may be either predispose a patient to or result from nasal polyps.
