It is common for children with cleft palate to have associated problems with the middle ear. Most of these problems are caused by a malfunctioning of the Eustachian tubes which are small passages that lead from the middle ear to the throat. Their function is to allow pressure to equalize on the inside of the eardrum or tympanic membrane. They also serve to drain any fluid that may accumulate in the middle ear. Yawning allows air to pass through the Eustachian tubes to relieve pressure on the eardrum.
When the Eustachian tubes are not functioning properly, fluid can build up in the middle ear, causing discomfort and temporary or even permanent hearing loss.
