Objective:To evaluate the efficacy and safety of posterior nasal neurectomy on the treatment of nasal congestion, rhinorrhea, sneezing, and post-nasal discharge in intractable rhinitis patients.

Methods:Design: Preliminary case series. Setting: Tertiary University Medical Center. Participant: Ten (10) patients with intractable rhinitis underwent endoscopic posterior nasal neurectomy in both sides. Symptoms were compared pre- and post-operatively one month and one year after surgery using Visual Analog Scale (VAS) scores. Endoscopic pre- and one-month post-operative Lund-Mackay scores were also compared.

Results:All four mean nasal symptom scores were reduced significantly at 1-month follow-up for nasal congestion (1.5 ± 1.08 vs 4.1 ± 0.5687, p = .00001), rhinorrhea (0.7 ± 0.823 vs 3.4 ± 0.966, p = .00001) post-nasal discharge (0.9 ± 0.994 vs 2.4 ± 1.5, p = .03), and sneezing (1.1 ± 0.738 vs 3 ± 0.943, p = .02). Mean endoscopic scores were also reduced significantly at one month, from 12.9 ± 2.55 to 4.2 ± 3, p = 0.0001.In the 6 patients that followed up at 1-year, post-operative mean nasal symptoms were still significantly better for congestion (0.6667 ± 0.8165 vs 4 ± 0.632, p = 0.00001), rhinorrhea (0.6667 ± 0.5164 vs 3.67 ± 1.033, p = .001), post-nasal discharge (0.1667 ± 0.40825 vs 2.17 ± 1.835, p = .033), sneezing (0.5 ± 0.54772 vs 3.17 ± 0.983, p = 0.0001). Mean post-operative VAS nasal scores and endoscopic scores were well associated (Correlation Coefficient -.648, p = .048).

Conclusion:Posterior nasal neurectomy could be considered as a safety and effective way to treat intractable rhinitis patients in Vietnam.
