The present paper was aimed at the study of the peculiarities of the
mucociliary system of the mucous membrane normal human frontal
sinus (FS). Cadaveric material obtained from people of both sexes aged
26 to 75 years who died of causes not related to pathology of the
paranasal sinuses has been studied in accordance with international
guidelines for biological research. After obtaining the mucous
membranes of the FS, their fragments were fixed in phosphate buffered
2.5% glutaraldehyde solution and embedded in the Epon-812 epoxy
resin. The obtained preparations were studied on the “Konus” light
microscope, equipped with the Sigeta DCM-900 9.0 MP digital
microphoto attachment and the Вiorex 3 (serial number 5604) software,
adapted for the above studies. The resulting morphometric digital data
were subject to statistical processing on a personal computer using the
Statistica 13 and Microsoft Excel 2010 software packages. The
investigated glands are complex alveolar-tubular glands, which consist
of a system of excretory ducts with the acini. The findings of our study
showed a certain difference between the structure of the acini of the
glands on the inferior wall, where they were divided into 2 types. The
first type is characterized by the formation of the acini by the cuboidal
cells, and the second type by the pyramidal cells. By the secretory
products, the glands of the inferior wall are defined as proteinaceous and
mucous, and the glands of the posterior wall are mixed. The
morphometry showed that the values of the average thickness (µm) of
the submucous layer of the posterior wall (PW) on both sides were by
74% lower compared to the parameter for the inferior wall (IW). No
significant difference in the outer diameter (µm) of the acini of the
glands of the specified walls on both sides was found.
