The Eustachian tube connects the throat and the middle ear (the site of a typical  ear infection ) and allows air to travel between them and equalize the pressures. When the Eustachian tube is temporarily pinched off, pressure can build up in the middle ear.
Visitation is a matter of state law, but generally speaking, every state allows parents to exercise a reasonable amount of visitation with their children, which generally means enough time to establish and maintain a meaningful relationship.
On the other hand, a visitation also offers informal time for gathering and remembrances, but the casket is either closed or not there at all. A visitation without the casket present can be scheduled anywhere, anytimeâwithout the cost or formality of funeral home involvement.
