A novel simplified method for endoscopic posterior nasal neurectomy for the management of allergic rhinitis

Surgical management can be considered in patients with allergic rhinitis (AR) refractory to drug therapy, posterior nasal neurectomy (PNN) is one of the procedures. We developed a unique and simplified method for PNN, we called modified PNN (MPPN) and investigated the improvement in nasal symptoms after MPNN surgery for allergic rhinitis, other surgical outcomes, and surgical complications. In MPNN, following sufficient coagulation of the mucosa along the base of the inferior nasal turbinate, a full thickness mucoperiosteal incision up to the bony turbinate was performed using energy devices. Surgical manipulations to confirm the posterior nasal nerve, such as elevation of the mucosa, are not necessary with MPNN. MPNN was a simple and safe procedure, and no serious surgical complications were observed. Significant improvement in postoperative nasal symptoms and reduction in medication use compared to preoperative conditions.
