[Local hyperthermia of upper respiratory passages for perennial allergic rhinitis].

Local hyperthermia (43 degrees C) to the upper respiratory passages, without supplementary drugs, relieves symptoms of perennial allergic rhinitis. Treatment consisted of 3, 30 minute sessions at 1-hour intervals during a single day. 69% were free of their symptoms during the month following treatment, and 52, 37 and 28% were free for 4, 8 and 12 months, respectively. The accumulated clinical experience with 95 patients aged 5-72 years demonstrates that local hyperthermia of the upper respiratory tract is effective in the treatment of perennial allergic rhinitis, with no immediate or long term side-effects.
