Parameters of local and integral mucociliary clearance in the postoperative period in patients with foreign bodies in the maxillary sinus

Objective: to evaluate the local and integral parameters of the mucociliary clearance (MCC) of the nasal cavity in the postoperative period in patients with foreign bodies in the maxillary sinus using various methods of surgical approach to the maxillary sinus. Material and methods. The study performed in 90 patients with foreign bodies in the maxillary sinus and 60 healthy individuals. To evaluate MCC, we used the technique of high-speed digital video recording of the microscopic picture of the specimen and saccharin test; computed tomography (CT) data. Results. Local MCC in the rhinological healthy individuals in our study was 10.84±3.80 Hz. There is a linear correlation of the local MCC and the saccharin test with inverse mean strength (r=-0.64). Local MCC depend on the type of surgical approach; the saccharin test do not reflect the nature of the surgical injury and quickly normalized. The degree of pathological changes in the area of the ostiomeatal complex on the computed tomogram, correlates with the local MCC before and after surgery. Conclusion. The measured indicator of local MCC characterizes the processes in the area of the ostiomeatal complex and correlates with CT; the values of local MCC due to surgical trauma decrease for up to 3-5 months. The saccharin test is not a method for determining the osteomeatal complex function and cannot be used as a diagnostic criteria. The method of investigation of local MCC can be used as a criterion for choosing surgical access to the maxillary sinus.
