title: Impact of Endoscopic Sinus Surgery on Symptom Manifestation of Chronic Rhinosinusitis.
abstract: BACKGROUND
  Rhinosinusitis is a significant health problem which results in large financial burden on society. The study evaluated the prevalence and severity of individual symptoms of chronic rhinosinusitis (CRS) and the impact of endoscopic sinus surgery (ESS) on the symptoms and medication used in patients with CRS.
  
  
  METHODS
  Patients with refractory CRS were assessed prospectively with ESS intervention. We studied the symptoms, change in medical therapy, complications of surgery and effect of other factors like smoking, polyposis and asthma on endoscopy and computed tomography scan scores.
  
  
  RESULTS
  A total of 81 patients underwent ESS for CRS. Post nasal drip (95%), headache (91%), nasal discharge (90%) and nasal obstruction (86%) were the commonest symptoms. Postoperatively, the highest improvement was seen in nasal blockage (87.2%), postnasal drip (84.4%) and headache (82.4%). Endoscopy scores were significantly worse in patients with polyps, asthma and smoking. A significant reduction in use of antibiotic and antihistaminics was seen post surgery. Seven patients who had extensive polyposis preoperatively, had recurrence and required revision surgery. Nasal synechiae formation and mild bleeding were the minor complications.
  
  
  CONCLUSIONS
  Endoscopic sinus surgery results in significant improvement in the symptoms of patients with CRS alongwith a definitive decrease in antibiotic and antihistaminic requirement. We conclude that ESS is an effective treatment for CRS in those who fail to respond to medical treatment.
