Introduction: Chronic rhinosinusitis (CRS) is a chronic inflammatory state described by nasal and paranasal sinuses mucosal inflammation. Nasal polyps are defined as inflammatory outgrowths that typically arise from ethmoid sinuses and have the tendency to recur after surgery.
Objectives: To search for the role of posterior nasal neurectomy (PNN) in management of recurrent cases and improvement of allergic symptoms.
Methods: fifty candidates were included in our study who had Functional Endoscopic Sinus Surgery (FESS) alone on the right side and FESS combined with posterior nasal neurectomy on the left side.
Results: No discrepancy regarding recurrence of nasal polyps after our procedure was found (P value=0.09), while allergic symptoms like nasal rhinorrhea and sneezing have markedly improved (p value< 0.001).
Conclusion: PNN is a minimally invasive technique which can be done to treat sneezing and rhinorrhea.
