Objective. Intranasal corticosteroids (INCS) are first-line medications for moderate to severe allergic rhinitis (AR). Patients who have had nasal congestion for many years often develop inferior turbinate (IT) hypertrophy. Some patients are refractory to INCS yet decline to receive allergen-specific immunotherapy. IT reduction is then indicated. There have been very few studies evaluating the allergic biomarker changes after IT reduction in AR. This study aimed to determine the effect of potassium titanyl-phosphate (KTP) laser IT surgery on eosinophil influx after challenge with dust mites. Study Design. A randomized prospective controlled study. Setting. Tertiary academic rhinology clinic. Subjects and Methods. Thirty-five house dust mite AR patients were randomly assigned to receive either INCS or KTP laser IT surgery. On the first visit, 2 nasal lavages prior to and 6 hours after challenge with Dermatophagiodes pteronyssinus were performed before receiving treatment. On the second visit, 3 months after treatment, the same procedures were repeated. No antiallergic medications were allowed for 2 weeks before each visit. Net changes in eosinophil numbers in the lavages were compared at baseline and 3 months after treatment and between the 2 treatments. Results. Treatment with KTP laser IT surgery resulted in a significant reduction in eosinophil influx after nasal challenge (P = .013), whereas such a reduction was not shown in the control. However, the net changes in the percentage of eosinophils were not different between the 2 groups at either visit. Conclusion. KTP laser IT surgery reduces eosinophil influx after nasal challenge in perennial AR.
