Aim  to obtain the values of local mucociliary clearance (MCC) of the middle nasal meatus in normal conditions and in patients with foreign body in the maxillary sinuses.&#x0D;Material and methods. To assess the local MCC, we used the original method of modern high-speed digital video recording of the microscopic picture of the specimen, followed by its mathematical processing. The study included a group of rhinologically healthy individuals (60 people) and a group of patients with foreign body in the maxillary sinus (90 people).&#x0D;Results. We obtained the standard values of MCC in rhinologically healthy individuals (11.76  3.01 Hz). In patients with foreign body in the maxillary sinuses, there was a correlation of the local MCC index with the severity of morphological changes, registered by computed tomography (CT), of the paranasal sinuses in the area of the middle nasal meatus and adjacent sinuses. Depending on the results of CT scanning, we identified 3 groups among the patients with foreign bodies in the maxillary sinuses  no morphological changes (CT1), changes outside the ostium (CT2) and pronounced morphological changes in the middle nasal meatus and surrounding paranasal sinuses (CT3). In the CT1 group the average values of the local MCC of the middle nasal meatus were 13.53  2.46 Hz; in group CT2  11.71  2.02 Hz; in the CT3 group  6.84  3.48 Hz. The differences in indicators in groups were statistically significant according to the Mann  Whitney test. The average value of the local MCC of the middle nasal meatus in patients without maxillary sinus mycetoma was 13.30  2.91 Hz, in patients having maxillary sinus mycetoma  10.74  3.69 Hz; this difference was also statistically significant.
