Risk Factors Involved in Recurrence of Chronic Rhinosinusitis After Functional Endoscopic Sinus Surgery in Kashmiri Population.

Abstract

BACKGROUND: Chronic rhinosinusitis (CRS) is one of the most common chronic diseases, which is defined as an inflammation of the nose and paranasal sinuses. Computed tomography (CT) scan of paranasal sinuses has become mandatory for all patients undergoing functional endoscopic sinus surgery (FESS), which is, nowadays, regarded as the gold standard for treatment of CRS after a trial of medical treatment. Our aim in this study is to explore the risk factors and anatomical findings on CT scan of CRS patients who had recurrence after undergoing FESS in Government Medical College,Srinagar . METHODS: A retrospective chart review study was conducted in the department of otolaryngology head and neck surgery,GMC Srinagar, to assess the risk factors of patients with recurrent CRS after FESS. The study included all patients, who were adults 18 years of age and above of both genders that had FESS after a diagnosis of CRS between 2017 and 2019. RESULTS: The study identified 129 patients with CRS, of which 19 (14.79%) patients had recurrence after FESS. Various risk factors were taken into consideration such as age, gender, airway and inflammatory autoimmune diseases, smoking, type of sinusitis, and anatomical variations and findings on CT scan. However, only fungal type of sinusitis was found to be a significant risk factor of a recurrent CRS. Anatomical findings on CT scan postoperatively were mucosal thickening, nasal polyps, nasal septum deviation, and obliterated osteomeatal complex. CONCLUSION: CRS patients were assessed for various risk factors of recurrent CRS. The overall incidence of recurrent CRS was 14.79%. Fungal rhinosinusitis was found to be a significant risk factor. The most common anatomical findings on CT scan postoperatively were mucosal thickening in paranasal sinuses followed by nasal polyps.
