Laser Surgery of the Inferior Turbinate for Allergic Rhinitis with Seasonal Exacerbation: An Acoustic Rhinometry Study

Abstract

Laser surgery has been used to successfully treat patients with perennial allergic rhinitis. We examined whether the numbers and types of sensitized allergens influence the effects of surgery. Two different groups (those allergic to house dust mites only, and those allergic to house dust mites and Japanese cedar pollen) prospectively underwent the same course of laser turbinectomy during the pollen dispersion season. The symptom scores for nasal obstruction significantly decreased in both groups, but the improvement of sneezing and rhinorrhea was less pronounced in the pollen group. We used acoustic rhinometry to measure postoperative changes in the nasal dimensions. Four months after treatment, the minimum cross-sectional area and nasal cavity volume had increased, respectively, by 61.7% and 30.7% in the house dust group, and by 30.7% and 16.2% in the pollen group. We conclude that laser surgery can be successfully applied to patients whose allergies show seasonal exacerbation by airborne pollen.
