In 17 mucocele was involved, in 14 instancespyocele. In 80.7%, i.e. 25 patients it was primary disease - caused by inflammation, congenitaldeformities and abnormalities of the orifice of the paranasal cavity. All patients were operated - 15by the rhinoendoscopic technique, 6 by a combined approach (rhinoendoscopically and by theclassical approach), 10 by the classical approach. The follow up period of the patients is 3 monthsto 10 years. In 27 instances the condition was resolved by a single operation. A relapse occurred infour patients.
