One local doctor is trying to reverse deafness by using stem cells to grow new hair in the inner ear.
Few of us ever worry about the hair cells deep within our ears -- until it's too late. But gradually, either with age, exposure to loud noise or damage from medication, the few thousand hair cells with which each person is born die off, one-by-one, and hearing ability fades inexorably. Once the hair cells are gone, there's no getting them back.
