Abstract CRS is defined as the continuous presence of 2 or more nasal symptoms, including blocked nose; pain or pressure around the forehead, nose, or eyes; nasal discharge or postnasal drip; and reduced smell in the last 3 months. Nasal polyps are inflammatory outgrowths of paranasal sinus mucosa caused by chronic mucosal inflammation that typically arise from the middle meatus and ethmoid region. FESS is a set of minimally invasive surgical techniques which allow direct visual examination and opening of the sinuses and are used for the treatment of chronic rhinosinusitis which has not responded to medical treatment. The posterior nasal nerve is the dominant source of the parasympathetic, sympathetic, and sensory fibers that innervate the nasal respiratory mucosa. Therefore, posterior nasal neurectomy (PNN) may induce denervation of the nasal mucosa and may relieve the nasal symptoms of AR. Our study is Quasi experimental study was conducted in otorhinolaryngology department, Assuit university in which fifty patients above 18 years who were diagnosed to have allergic bilateral nasal polyps not responding to medical treatment and underwent FESS+PNN in the left side and were followed up for 1 year postoperative to evaluate the improvement in allergic symptoms and recurrence of nasal polyps. Our research has found out that PNN is safe effective mean to control sneezing and rhinorrhea which are the main symptoms of allergic rhinitis but it can’t make an obvious improvement in anosmia. As for recurrence of nasal polyp, it’s due to multiple factors, so PNN doesn’t play any role in prevention of recurrence of nasal polyps. To be concluded, PNN is minimally invasive procedure which is easily applicable and safe surgical procedure which can be done to treat intractable allergic rhinitis especially sneezing and rhinorrhea. |
