Rhino sinusitis, is a common inflammatory disease that affects the nasal cavity and paranasal sinuses in millions of individuals. Chronic sinusitis patients complain of a combination of nasal obstruction, rhinorrhea, post nasal drip and facial pain. To identify the risk factors of the recurrence of nasal polyps in chronic rhino sinusitis patients after endoscopic sinus surgery. After a review of 60 patients with chronic rhino sinusitis with failed medical treatment requiring FESS presenting in Kasr Alainy Hospital in Cairo University and October 6 University Hospital from May 2022 to March 2023. All patients were subjected to history taking, clinical examination including endoscopy, subjective evaluation of symptoms and CT-scan. Of our patients, six patients (15%) were diagnosed with recurrence of nasal polyps with chronic rhino sinusitis and needed revision surgery. There are multiple risk factors related to the recurrence of nasal polyps including smoking followed by having a history of an asthma, the presence of an allergy, septal deviation, prior sinus surgery, and turbinate hypertrophy. Other factors, as proper medical treatment such as topical steroids and treatment of allergy had a significant role in decreasing the recurrence rate. Risk factors related to the recurrence of nasal polyps should be avoided before surgery. The avoidance of risk factors protects the patients from the recurrence of nasal polyps, the hazards of anaesthesia on surgical treatment, and the financial cost of surgery.
