Assessment of Nasal Obstruction in Patients Undergoing Functional Endoscopic Sinus Surgery

Aim & objectives-To assess and compare the nasal obstruction in patients before and after undergoing FESS using Visual analogue scale, Rhinomanometry and Diagnostic nasal endoscopy. Introduction- Chronic Rhinosinusitis with, or without nasal polyps can lead to nasal obstruction. Patients refractory to medical treatment undergo Functional endoscopic sinus surgery (FESS). FESS has been shown to improve subjective quality of life outcomes and objective endoscopic improvement. Material & methods- A prospective study conducted in the department of Ear, Nose & Throat, of a tertiary care medical college and associated Hospital between January 2021 and October 2022. Subjective and objective assessment of nasal obstruction was done using Visual analogue scale, Rhinomanometry and Diagnostic nasal endoscopy before and after surgery at 1st, 3rd and 6th month. Results- Post FESS, there was a significant improvement in nasal obstruction on Visual analogue scale, sinuses were healthy and drainage was adequate on Diagnostic nasal endoscopy, statistically significant (P < 0.05) decrease in nasal resistance was seen on Rhinomanometry. Conclusion- A good subjective outcome on Visual analogue scale and a good objective outcome on Diagnostic nasal endoscopy and Rhinomanometry can be obtained with FESS in patients with Chronic Rhinosinusitis.
