[Otorhinolaryngological aspects of headache: (author's transl)].

Since about 20% of the patients in a headache clinic have ENT complaints an ENT specialist should be consulted for diagnosis and treatment. It is very important to know what structures in the head and neck are sensitive to pain for diagnostic and differential diagnostic purposes. Primary and secondary neuritis are headache mechanisms in otolaryngology and also tension headache, which is specially discussed. Rhinogenous contact headache and headache as cardinal symptom in various syndromes are also stressed as specific to ENT. Finally a scheme is given for investigating a headache patient from the otolaryngological point of view.
