Controversial. Most doctors agree that tubes may help prevent hearing loss from chronic or frequent ear infections.
Hearing, infections. Hearing loss for about 12 weeks, or needing many antibiotics for infections are the main reasons to put in ear tubes.
Varies. I generally send kids for consultation when there is 5 or more infections per year or a continuous infection that won't clear within 90 days. The ENT's may factor in other variables like severity of infection, time of year, etc.
