Retrospective analysis of the effectiveness of functional endoscopic sinus surgery in the treatment of adult chronic rhinisinusitis refractory to medical treatment.

Chronic rhinosinusitis (CRS) is a common disease that restricts the quality of life of millions of involved patients. The aim of the study was to evaluate how functional endoscopic sinus surgery (FESS) modifies patients symptom profile and to also confirm that FESS is the modality of treatment in patients with refractory CRS. The study was retrospective analysis. 105 patients with symptoms of CRS were included in the study (between August 2006 to July 2009). Patients were assessed for CRS symptoms preoperatively and postoperatively using grading symptoms. Statistical analysis using Chi square test. Leading symptom of CRS was nasal obstruction followed by headache. Furthermore patients reported of anosmia, facial pressure, postnasal drip, purulent nasal discharge, halitosis, dental pain, cough, earache. None of the patients had fever as their complaint. After a postoperative followup of 6 months there was improvement in the symptoms. All minor symptoms had 100% improvement. Nasal obstruction responded best, next followed by (all symptoms P value <0.001). An overall improvement of 86.66% was recorded. The restriction of quality of life in patients with CRS is mainly caused by these symptoms, which can be improved in excellent fashion by FESS in majority of the patients.
