Abstract

Objectives: To investigate the impact and predictors of tympanostomy tube (TT) extrusion.

Methods: A retrospective study on 258 ears underwent TT insertion during 2016-2018 at King Abdullah Specialized Children's Hospital, Riyadh, Saudi Arabia. Patients were followed for 36-48 months postoperatively to detect the recurrence rate. The sample was divided into 2 groups based on extrusion time and were compared to determine the predictors of TT extrusion.

Results: Otitis media with effusion (OME) recurrence after TT insertion was detected in 28.7%. A shorter TT extrusion time was associated with a higher recurrence (p=0.002). Small TTs increased the probability of early TT extrusion (odds ratio = 5.144; 95% confidence interval: [1.602-16.519]).

Conclusion: More than one-fourth of the patients who underwent TT insertion for OME developed recurrence. Tympanostomy tube extrusion earlier than 12 months was associated with a higher recurrence rate. Small TTs increased the probability of early TT extrusion.

Keywords: extrusion; otitis media; predictors; recurrence; tympanostomy; ventilation tube.
