Persistent otitis media with effusion may or may not delay language development in small children. Either way, treatment with ventilation tubes had no effect on language development in one randomised trial ( The 187 participants were all under 3 years old. Treatment with ventilation tubes had no discernible impact on expression or comprehension when compared with a strategy of watchful waiting.
