Study limitations
We have only begun to adopt TEES for the management of middle ear
disease in recent years. The number of patients in our study was still
limited, especially in the pediatric group. Furthermore, the follow-up
period was not long enough (18-to 48 months) to obtain long-term
results. We think that additional studies with more patients and
long-term follow-up may be required to generate more definitive
conclusions.
