[Diagnostic value of computer tomography of paranasal sinuses in qualifying for functional endoscopic sinus surgery (FESS)].

Functional endoscopic sinus surgery (FESS) introduced in the recent years by Messerklinger, Stammberger and Kennedy gained undisputable reputation as method of choice in treatment of nose and nasal sinus diseases. The introduction of this method was possible, among others, due to precise radiological diagnostics (CT). Traditional radiological examinations of nasal sinus do not allow for detailed diagnostics and analysis of anatomic anomalies such as: dehiscention in vicinity of carotic artery or ophtalmic nerve which have basic significance while establishing surgical risk. The paper presents 20 cases of nasal sinus CT of patients qualified for functional endoscopic surgery comparative analysis with traditional radiograms were performed.
