CORRELATION BETWEEN COMPUTED TOMOGRAPHY AND INTRAOPERATIVE FINDING IN FUNCTIONAL ENDOSCOPIC SURGERY OF NOSE AND PARANASAL SINUSES
Department of Otorhynolaryngology, General Hospital Izola, Slovenia
Medical literature lacks sufficient data that compare preoperative computed tomography and intraoperative findings during endoscopic surgery of nose and paranasal sinuses.
The aim of the paper was to determine the practical value of CT in preoperative preparation for functional endoscopic surgery of nose and sinuses.
Cadaver head was placed in CT with subsequent scanning changing window (W) and center (C) parameters. Forty patients treated in ENT Department of Vranje and Isola were also included. Routine radiography and CT (SIMENS Smile, SIMENS Somatom 4, and spiral Simens Fach) were performed. Obtained values were compared with intraoperative findings.
We found significant difference in intraoperative findings and radiography, and intraoperative findings and CT, in favour of CT data. Contrary to this, there was no significant difference between these comparisons for cystic changes and effusion in paranasal sinuses.
CT gave significantly better agreement with intraoperative findings when compated to classic radiography. Exact diagnosis was found in 90.7% on classic radiography, and in 87.8% on CT scan. Acta Medica Medianae 2010;49(3):19-26.
