[Nasal and cerebral blood filling in patients with congenital cleft palate and allergic rhinitis].

Nasal mucosa and brain blood content was studied by rheographic methods in 100 normal subjects aged 4 to 48, in 184 patients with various types of cleft palate, and in 129 ones with allergic rhinitis. A combined restructuring of the nasal and cerebral blood content was revealed in the patients, seen first of all on rheoencephalograms; other shifts included increased vascular tone and impaired venous outflow.
