Abstract
An initial treatment with several kinds of anti-allergic medicines is useful for reducing nasal allergy symptoms in patients suffering from Japanese cedar pollinosis during the pollen season. Since laser surgery before the pollen season seems to have a preventive effect as well, it would be of interest to know the time course of changes in the nasal reactivity to specific and non-specific stimuli after laser surgery. In this study, we investigated the changes in the nasal reactivities to specific antigen and histamine after CO 2 laser surgery. The nasal reactivities to both specific antigen and histamine were enhanced 2 weeks after the laser surgery. On the other hand, they were significantly reduced after 4 weeks. Our data strongly suggest, therefore, that laser surgery must be done more than 4 weeks before the start of the pollen season to avoid temporary enhancement of nasal allergy symptoms.
