[Microcirculation in nasal mucosa of healthy subjects and patients with rhinitis and maxillary sinusitis].

Laser Doppler flowmetry was used to determine normal parameters of microcirculation in the nasal cavity and their changes in different forms of rhinitis and maxillary sinusitis. The latter condition was shown to be associated with altered frequency and amplitude characteristics of microcirculation in nasal mucosa at the affected side. These changes can be used to evaluate efficacy of the on-going treatment. Stimulation of sympathetic innervation in patients with vasomotor rhinitis induced local pathological reactions of the microcirculatory bed in the mucous membrane of inferior nasal conchae. No such reactions developed in patients with year-round allergic rhinitis and in healthy subjects.
