Nasopharyngeal polyps occur in the nasal cavity, oral cavity, nasopharynx, Eustachian tube and tympanic bulla. They often arise in the '''tympanic bulla''', extend down the Eustachian tube and enter the '''nasopharynx'''. They can also arise in the nose and extend into the nasopharynx or out of the nasal opening. Another possible origin is in the middle ear extending through the tympanic membrane into the '''external ear canal'''.
