Effect of Local Hyperthermia on Abnormal Sensation in the Throat

Abstract

We examined the effects of local hyperthermia by humidified aerosol at 43°C on blood flow in the epipharynx using a spectrum analyzer. We measured the blood flow in patients with epipharyngitis, abnormal sensation in the throat, before and after nasal hyperthermia, as well as in healthy subjects.
Epipharynx blood flow was high in the ep i pharyngitis group, and was decreased by local hyperthermia. Local hyperthermia normalized epipharynx blood flow in the group with abnormal sensation in the throat. In some patients abnormal sensation in the throat disappeared or decreased after local hyperthermia; therefore, this treatment appears to be useful.
