To investigate changes in the frequency of surgical interventions for subglottic stenosis over time.
Analyzed historical data on surgical interventions for subglottic stenosis.
Calculated annual reoperation rates and treatment-free intervals.
Reoperation risk declined by 7.7% per year.
Increased treatment-free intervals suggest a reduction in disease activity.
Abstract
The risk of reoperation decreased by 7.7%/yr. (p = 0.008), reflected in increased treatment-free intervals and interpreted as decreasing disease activity.
