The 6th most common chronic condition in geriatric patients is rhinosinusitis. The recent treatment modality for chronic rhinosinusitis in adults failing maximum medical therapy is FESS (Functional endoscopic sinus surgery). It has gained importance over the last 2–3 decades. The aim of this study was investigating the efficacy and safety of FESS in the elderly population as compared to the adult population. A retrospective review of outcomes was done in thirty–eight in patients over age of 60 years who underwent FESS and they were evaluated preoperatively and postoperatively at 3, 6, and 12 months with a rigid nasal endoscopy scoring system, and the SinoNasal Outcome Test–20 (SNOT–20) questionnaire. Data analysis was performed using the Student’s t test to compare mean scores. All complications were noted. And it was concluded that FESS in the geriatric population is a safe and effective treatment modality for rhinosinusitis which is refractory to medical therapy.
