Anatomical Predictions of Development of Rhinosinusitis and Its Complications

Abstract

Background. The anatomical structure of the paranasal sinuses of a person predetermines the risk of development, diversity of presentation, possibility of complications and features of surgical treatment of rhinosinusitis. Objective: of our study was to determine the thickness and density of the walls of the maxillary and frontal sinuses, which are potentially dangerous in terms of the development of complications. Materials and methods: Our study involved 121 subjects without any ENT diseases, who underwent SCT examination due to the reasons that were not related to abnormalities of ENT organs. Thickness and density in the region of the lower (orbital) wall and posterior (cerebral) wall of the frontal sinus were calculated. Results and Discussion: The maximum density was characteristic of the lower wall of the frontal sinus under physiological conditions and appeared 107.96 ± 201.64 Hu, the minimum for the lower wall was -29.98 ± 208.54 Hu. The thickness of the bone tissue in the frontal sinus was 4.05 ± 2.04 mm. Conclusion: The minimum density and thickness of the lower and posterior walls of the frontal sinus and upper and lower walls of the maxillary sinus was established under physiological conditions. The density of the posterior wall was found to be 25.4% lower than the density of the lower wall, and the thickness 22.2% lower.

Morphometric Characteristics of the Glands of the Mucous Membrane of All the Walls of the Human Frontal Sinus in a Norme

“…The information obtained in the course of the study significantly expands knowledge about the structure of the human frontal sinus [4]. From the obtained data, it can be clearly seen that the mucous membrane of the inferior wall of the frontal sinus has the greatest functional load, since it has a connection with the nasal cavity in the middle nasal passage [3].…”

“…Pathological processes that occur in the FS as a result of its topography and anatomical connections with the surrounding anatomical structures most often lead to complications [3].…”

Morphofunctional State of the Maxillary Sinus Mucosa in Patients After Endoscopic Infundibulotomy

“…Despite the development of new technologies, classical surgical approaches in rhinosurgery have not lost their relevance. So it was proved that in chronic alterative, hyperplastic and mixed forms of CRS, changes in PNS are irreversible, which requires its complete removal [13]. In such cases, functional surgery, firstly, is not justified, and secondly, the surgical approach does not always allow to completely remove the altered mucous membrane of the affected sinus, taking into account the existing anatomical features (multichamber sinuses, hypergenesis, ostiomeatal complex formation) and radical surgical tactics are required.…”
