[Influence of the anatomical structure of the uncinate process on bone patency of the maxillary sinus: a radiological and clinical evaluation].

The group of 185 patients with chronic and acute recurrent rhinosinusitis was analyzed radiologically with CT scans. The anatomical structure of the uncinate in its upper part, configuration and position of its low margin were evaluated. The results have been compared to the normal CT scans of paranasal sinuses of 50 persons without any sinus disease. The significant correlation was found between the shape and the development of pneumatization of the turbinate and the configuration of the uncinate process as well as to its type. The degree of the pneumatization and configuration or hypertrophy of the turbinate correlate also to the maxillary sinus disease.
