Purpose: This systematic review and meta-analysis evaluates the effect of TRNP on rhinitis-related symptoms.
Methods: We reviewed studies retrieved from PubMed, SCOPUS, Embase, the Web of Science, and the Cochrane database to June 2023. Studies that evaluated quality-of-life and rhinitis-related symptom scores before and after treatment were analyzed, as was one sham-treatment-controlled study.
Results: In total, 406 patients evaluated in five studies were analyzed. TRNP significantly improved rhinitis-related symptoms-congestion, itching, rhinorrhea, and sneezing-for up to 12 months after treatment, compared to before treatment. The most significant symptom decreases were those of rhinorrhea and nasal congestion. Rhinitis-related symptoms had improved significantly at 3 months after TRNP, compared to sham surgery. TRNP improved disease-specific quality-of-life scores on the Rhinoconjunctivitis Quality of Life Questionnaire at 6 months after treatment, compared to before treatment. The rates of clinical improvement in terms of all nasal symptoms (reduction > 30% from baseline) and in quality of life (minimal clinically important difference > 0.4) after TRNP were 79% and 84% respectively. There was no severe adverse event associated with either device use or the overall procedure.
Conclusions: TRNP treatment improved subjective symptoms related to rhinitis, especially rhinorrhea and nasal congestion, and also improved disease-specific quality-of-life scores.
