Study of chronic sinusitis to radiological and diagnostic nasal endoscopic examination findings

Introduction: Chronic sinusitis is a very common problem in ENT practice. Variations have an anatomic and surgical significance, each and every case should be individually studied in detail before surgery to maximize patient benefit and avoid serious complications. Aim: To study the anatomical variations in relation to radiological findings occurring in nose and PNS in chronic sinusitis patients using CT scan PNS and DNE (Diagnostic nasal endoscopic examination). Materials and methods: Study done on 50 patients in duration of study 2 years, cases of chronic sinusitis chronic sinusitis with symptoms such as purulent rhinorrhea, nasal congestion, headache, facial pain or pressure persisting beyond 12 weeks who had not demonstrated symptom resolution despite 3-6 weeks antibiotic therapy, with systemic steroids, decongestants and nasal saline irrigation were included in the study. Results: In this study 42 cases showed anatomical variations out of 50 cases (ranging from 2.3% to 57.1%). Mixed signs and symptoms are most common observation, Incidence of Symptoms ranges from 20% to 90% and Signs ranges from 10% to 90%. More than one sinus bilaterally involved (68%). Conclusion: CT scan of the paranasal sinuses is the investigation of choice. Diagnostic nasal endoscopic examination is the clinical guide to evaluate the disease and the severity of the anatomical abnormality.
