An otolaryngologist or ear, nose, and throat physician (ENT) is a medical doctor (MD or DO) that examines and treats problems associated with the ears, nose, throat and related structures of the head and neck.  The otolaryngologist trains at least five years in this field after medical school.

This head and neck surgeon also performs and supervises hearing and balance testing and diagnoses and treats common problems such as ear infections, tonsillitis, and sinusitis as well as more serious infectious diseases of the head and neck such as cancer.

In addition, an otolaryngologist fits people for hearing aids and performs surgical cochlear implants, among other treatments. After passing a national examination, the otolaryngologist can be board certified by the American Board of Otolaryngology.

Mucous membranes are tissues that line body cavities or canals such as the throat, nose, mouth, urethra, rectum and vagina. Mucous membranes produce a thick, slippery liquid called mucus that protects the membranes and keeps them moist.
