Introduction: Chronic rhinosinusitis (CRS), with or without nasal polyps, is characterized by the inflammation of the nose and paranasal sinuses. To make the diagnosis of CRS, a patient must exhibit 2 or more of the following symptoms for at least 12 weeks time period: nasal obstruction, nasal blockage, or congestion, and/or nasal discharge (which could be anterior or posterior nasal drip), along with possible facial pain or pressure, and/or a reduction or loss of smell. This diagnosis must be supported by observable disease signs, which can be identified through an endoscopic examination showing nasal polyps, mucopurulent discharge, or edema/mucosal obstruction.Methods: A prospective study will be conducted on all the patients with clinical diagnosis and suspicious of CRS, referred from OPD / wards of ENT and HNS to the department of radiodiagnosis of Muzaffarnagar Medical college, for diagnosis and evaluation of patients. Diagnosis will be made based on clinical and radiological findings. A brief clinical history of the patient will be taken from the patient or by the attendant.Results: In this study involving 40 participants, nasal mass was observed in 42.5%, while nasal bleed occurred in 47.5% of participants. X-ray opacification of sinuses varied, with opacification in all sinuses seen in 22.5% of cases and various bilateral and unilateral patterns in others. Polypoidalmass was present in 12.5% of participants. Bony changes included erosion in5% and sclerosis in 22.5% of cases. Deviated nasal septum was observed, with left deviation noted in 10% and right deviation in 15% of participants.Conclusion: this study of 40 participants revealed a male predominance and a mean age of 39.8 years, with no significant age difference between genders. Common symptoms included nasal obstruction, nasal discharge, sneezing, headache, facial puffiness, and altered smell. Nasal mass and nasal bleed were frequent, while X-ray opacification of sinuses showed diverse patterns. Polypoidal masses were observed in a notable percentage of participants.
