Development of a standardized proforma for reporting computerized tomographic images of the paranasal sinuses.

The complex regional anatomy of the paranasal sinuses has only recently been elucidated through the use of modern imaging techniques. The advent of computerized tomography in the delineation of sinonasal pathology and anatomic variation has proven invaluable to the otolaryngologist in preoperative planning for functional endoscopic sinus surgery (FESS). Frequently, the radiologic reporting schemes for these studies are not standardized, and in many respects have been found to be inadequate. This study attempts to develop a simple reporting proforma that the head and neck radiologist can routinely use in order to facilitate the presentation of CT scan findings in evaluating sinus, nasal, or upper airway pathology. Over 100 CT sinus reports that had previously been reported were re-read according to this reporting scheme and were analyzed in order to determine whether any significant discrepancies existed. These differences were then classified according to their incidental, minor, and major surgical significance. It is hoped that through the development of a standardized proforma, the complementary relationship between preoperative imaging and endoscopic intervention can be consolidated and further enhanced.
