Optimal computed tomographic (CT) examination technique for microendoscopic sinus surgery.

AIM

Functional endoscopic sinus surgery is widely utilized to assess and treat inflammatory sinonasal diseases. The use of this surgical technique has resulted in a dramatic increase of the radiologic studies carried out as part of presurgical preparation. Computed tomography (CT) has become a standard for pre-endoscopic and postoperative assessment of the paranasal sinuses. In our study we aimed at finding the optimal imaging technique for CT examination of the sinuses.

MATERIALS AND METHODS

We examined 60 patients with inflammatory sinonasal diseases using Sytec 3000 CT scanner. The scans were performed in the coronal and axial plane. The kilovolt peak was kept constant and the milliampere second setting was reduced without image compromise.

CONCLUSION

CT study is a method of choice in diagnosing inflammatory diseases of the sinuses. The technique we suggest in the study provides maximal diagnostic information at reduced cost and radiation exposure of the patient.
