Conclusion
A negative correlation was found between the nasalance score and the
severity of rhinosinusitis in our cohort. Although unilateral CRS had a
relatively lower disease burden, abnormal nasality was still reported in
one-third of the patients preoperatively. The nasalance score
significantly increased 1 year after FESS, particularly in patients with
higher disease severity who received wide opening surgery.
The increase in the nasalance
score may represent a return to a normal status since the self-reported
nasality assessment was significantly improved postoperatively.
