About 700,000 US children need ear tube surgery each year. Earflo is a medical device designed as a sippy cup for kids as young as 2, that helps relieve the negative middle ear pressure that leads to the need for ear tubes.
When you sip from the cup, a small mask forms a seal on your nose, and with each swallow, air flows through the nose. The pressure on the nasal cavity helps open the eustachian tubes in the ear, releasing trapped fluid. In an early peer-reviewed study of 21 children aged 1 to 12 using Earflo for four weeks, 90% of participants did not need ear tube surgery three months later.
