Features of diagnostics of fungal ball of paranasal sinuses of iatrogenic genesis

Abstract

Introduction: There are various theories of the origin of areas with high radiation density in the fungal ball of the paranasal sinuses: X-ray contrast dentist filling material; accumulation of zinc due to enzymes of the metalloproteinase group; formation of osteophytes, etc. The purpose of the study: to study the chemical composition of areas of fungal balls that have high radiological density. Methods and materials: The results of research of 26 samples of fungal bodies by scanning electron microscopy and spectrometry removed from maxillary sinuses in patients with fungal sinusitis (4 – nonodontogenic, 22 – odontogenic origin) are presented. In addition, 5 types of material most commonly used for endodontic treatment were studied. The results: It was found that fungal bodies of odontogenic origin have a heterogeneous structure with the presence of crystalline inclusions, the elemental composition of which has the characteristics of materials for endodontic treatment (Ba, Zr, W, Co), or increased content in the fungal ball of trace elements (Ti, Al and Zn), in quantities that are not characteristic of organic compounds. Conclusions: Scanning electron microscopy in combination with spectrometry can be used to identify foreign bodies of the maxillary sinus of exogenous (iatrogenic) origin and determine their role in the development of the fungal ball.
