Merkulov A. Clinical and experimental grounds and comparative analysis of minor invasive interventions at maxillary sinuses

The dissertation concerns the problem of increasing of efficiency in diagnosis of chronic proliferative maxillary sinusitis and optimization of minor invasive interventions at maxillary sinuses in the patients with chronic maxillary sinusitis. The complex investigation of interrelation of the variants in anatomic structure of nasal cavity septum, ostiomeatal complex and inferoorbital ethmoidal Haller cells with chronic inflammatory proliferative diseases of maxillary sinuses mucosa has been carried out; it included histological confirmation of X-ray alterations in maxillary sinuses mucosa (spiral computed tomography findings) which are characteristics for chronic proliferative maxillary sinusitis. According to the studied sufficient X-ray material (448 patients and 110 controls) a significant correlation has been identified only at some variants of nasal cavity septum deformations and chronic maxillary sinusitis as well as at definite variants of nasal cavity septum deformations and maxillary sinusescysts. As for the rest cases, the etiological role of ostiomeatal complex structures in the development of chronic maxillary sinusitis should be considered only from the point of view of their influence on the conductivity of natural co-ostium of maxillary sinuses.
