[Results of the treatment of patients with chronic purulent maxillary sinusitis evaluated by laser Doppler flowmetry].

Laser Doppler flowmetry (LDF) was used to study microcirculation in mucous membranes of the nasal cavity and maxillary sinuses of 60 patients with chronic purulent maxillary sinusitis . The treatment included local infrared therapy (IR therapy) and lavage of the maxillary sinuses with a colloid solution containing silver ions. Post-treatment analysis of LDF data showed impaired microcirculation and shunt indices, increased coefficients of variation and microcirculation efficiency at the affected side. These findings confirm high effectiveness and safety of IR therapy and lavage of the maxillary sinuses with a colloid solution containing silver ions for the treatment of patients with chronic purulent maxillary sinusitis. It is concluded that LDF can be used as an additional, objective and highly informative, non-invasive method for the diagnosis of chronic purulent maxillary sinusitis and evaluation of the outcome of its treatment. Persistent disturbance of microcirculation in the nasal cavity and maxillary sinuses of the patients with chronic purulent maxillary sinusitis observed in the present study may be a cause of chronic inflammatory process in the maxillary sinuses.
