Predictive factors for repeated tympanostomy tube placement in children

Area of Science:

• Otolaryngology
• Pediatric Otolaryngology
• Epidemiology

Background:

• Tympanostomy tubes (TT) are commonly placed in children to manage recurrent otitis media.
• Understanding factors influencing the need for repeat TT placement is crucial for optimizing patient care and resource allocation.

Purpose of the Study:

• To determine the rate of additional tympanostomy tube (TT) placement after the extrusion of the first set.
• To identify risk factors associated with the need for subsequent TT insertion in pediatric patients.

Main Methods:

• A single-centre cohort study reviewed clinical records of 183 children who underwent TT placement between January 2015 and December 2017.
• Factors associated with the need for a second TT insertion were evaluated using univariate and multivariate analyses.

Main Results:

• The rate of second TT insertion was 21.9%, with a mean TT retention time of 12.13 months.
• Shorter TT retention time (p<.001) and acute otitis media with effusion (RAOM) as an indication for surgery (OR: 5.767) were significant predictors for needing a second TT.
• Univariate analysis also identified otorrhoea, snoring, passive smoking, and rhinorrhoea as potential risk factors.

Conclusions:

• Acute otitis media with effusion (RAOM) and shorter tympanostomy tube (TT) retention time are significantly associated with the need for additional TT placement.
• These findings highlight the importance of close follow-up for children after initial TT extrusion, particularly those with identified risk factors.
