Efficacy of Adjuvant Sublingual Immunotherapy After Septomeatoplasty.

Abstract

The efficacy of adjuvant sublingual immunotherapy (SLIT) in correcting structural problems in patients with allergic rhinitis (AR) caused by mite who have undergone septomeatoplasty (SMP) has not been studied. This non-randomized controlled study recruited patients with AR (caused by mite) and concurrent septal deviation and inferior turbinate hypertrophy, at a tertiary hospital in Taiwan. SMP was performed on all patients as a surgical intervention. The patients were then divided into two groups: the control group, which underwent surgery only, and the experimental group, which received SLIT as an adjuvant treatment. Demographic data and rhinitis control assessment test (RCAT) results were analyzed. A total of 96 patients were enrolled in the study (SMP + SLIT group, n = 52; SMP only group, n = 44). No significant differences were observed in any of the variables between the two groups before and one month after surgery. However, during evaluations at the third and sixth month, the SMP + SLIT group showed significant improvement in the total RCAT scores compared to the SMP only group (28.6 ± 1.56 vs. 24.5 ± 3.66, p < 0.001; 27.1 ± 2.87 vs. 19.9 ± 5.56, p < 0.001). In addition, significantly better control of all RCAT sub-categories was observed in the SMP + SLIT group at the third and sixth month evaluations. SLIT may serve as an ideal adjuvant therapy after SMP in patients with AR. 3 Laryngoscope, 134:3073-3079, 2024.
