Chronic Polypous Rhinosinusitis. Genesis, Clinical Picture, Therapy And Relapse Rate - A Retrospective Study

Background. The prevalence of chronic polypous rhinosinusitis is high at 1-2%. In the present study, the predisposing factors for this condition, the clinical symptomatology, results of surgical interventions, significance of computed tomography diagnosis, as well as histology and post-operative therapy with steroids were investigated.Methods and results. A 15% stratified sample, made up of 194 post-paranasal sinus surgery patients of 5 surgical years was investigated. Above all, the eosinophil dominated type led to the formation of polyps. In the diagnosis of chronic polypous rhinosinusitis computed tomography is only sufficiently sensitive for the ethmoid bone. The complication rate was, with 4.6%, in the lower range of comparable pre-examinations. In addition, the 18% relapse rate in the patient population, of whom 49% had already been operated on once or several times, corresponds to a good result when compared at an international level.Conclusions. These data confirm that surgical experience and a consistent post-surgical treatment can reduce the relapse frequency of chronic polypous rhinosinusitis. This is indicated by the on average late occurrence of a relapse.
