Despite a numerous studies, the causes and conditions for development of chronic sinusitis (CS) have not been finally established. It is noted the multiplicity and variety of factors that determine the patterns of occurrence, development and outcomes of chronic sinusitis in each case. A special place within possible causes that create preconditions of functional and pathological changes in the mucous membrane of nasal cavity and paranasal sinuses take various development anomalies in the intranasal structures.
OBJECTIVE
Generalization and systematization of literature data on the prevalence and associations of excessive intranasal structures’ pneumatization with chronic sinusitis.
MATERIAL AND METHODS
Publications (articles and corresponding abstracts) presented in the PubMed, EMBASE, MedLine and Cochrane Library databases for the period 1995—2020 were used for the analysis.
RESULTS
The numerous studies indicate the pathogenesis role of the ostiomeatal complex obstruction in local inflammation and chronic sinusitis (CS) development. At this, the presence of various options for excessive pneumatization of intranasal structures is considered as a causal factor. However, the presence of certain anatomical anomalies of the nasal cavity is not a prerequisite for the sinusitis’ development. In practical terms, the more important factor is the size of the corresponding anatomical structures. The pathogenesis meanings of pneumatization variants of intranasal structures remains insufficiently studied still. At the same time, the assessment of the presence and, in particular, the size of hyperpneumatized anatomical structures should be taken into account when determining the probability of pathological changes in the PNS and planning their surgical correction.
