Some teams use the tongue lip adhesion method to hold the tongue down. Other, more severe cases, require tracheostomies to aid in breathing until the jaw can grow out and allow a place for the tongue to go. Other babies don't need anything special to breathe. It really depends on the child, the size of the chin and the tongue. These issues need to be discussed in detail with your child's medical team.
Dental issues are very common in PRS children.
The lower jaw sometimes does not grow to the same size as the upper jaw and the teeth are crowded. Many of these children go through orthodontics to correct teeth placement. Most school age children with PRS will require some speech therapy, especially to reduce nasality in their speech. The speech language pathologist will also work with them to correct bad habits. Make sure you request an evaluation if your school does not offer it.
