major patterns of inflammatory sinonasal disease in 77 cases of functional Endoscopic Sinus Surgery [FESS]

ABSTRACT

In the two past decade Functional Endoscopic Sinus Surgery [FESS] has appeared as a relatively benign surgical technique for treatment of chronic recurrent sinusitis. Coronal sinus CT Scan is the best method for properative evaluation. Identifying the major patterns of inflammatory sinonasal disese in CT scan is very helpful for planning the technique. These five major patterns are I] infundibular, II] ostomeatal unit or OMU, III] sphenoethmoidal recess or SER, IV] sinonasal polyposis or SNP and V] sporadic or unclassifiable. By identifying these patterns more tailored endoscopic sinus surgery is possible
