To understand how earaches begin, we must understand the Eustachian tube. This tube is a narrow channel which connects the inside of the ear to the back of the throat, just above the soft palate. In a healthy ear, this tube allows for drainage, preventing fluid in the middle ear from building up and bursting the thin ear drum. Ideally, fluid drains down the tube, assisted by tiny hair cells, and is swallowed.
As we covered before, approximately 1.1 billion teenagers and young adults around the globe face the risk of hearing loss. This high number comes from the increased levels of sound and noise that comes from recreational activities, like loud concerts, clubs/bars, and audio devices, like iPhones/Pods. Though we’re always telling the younger generation “hey, turn that down!” did you ever stop to think that the activities you’re involved in could have the same impact on your hearing?

New research has taken scientists on the first step to reversing hearing loss in adults, by revealing how the inner ear develops in mice embryos. Researchers at the Washington University School of Medicine in St. Louis, MO have used this mouse model to identify two signaling molecules called fibroblast growth factors (FGFs), which are required for the overall development of the cochlea.
