INFLUENCE OF SINONASAL ANATOMIC VARIANTS ON RECURRENT, PERSISTENT OR CHRONIC SINUSITIS - CT EVALUATION IN 112 PATIENTS

Using CT scan, we studied the influence of the most important sinonasa l anatomic variants on 112 patients, aged more than 16 years, sufferin g from recurrent, persistent or chronic sinusitis. The series was char acterized by the absence of: multifocal sinusitis, polyposis, dental o r mycotic sinusitis, traumatic, tumour, actinic or prior surgery. We c ompared our results with those of the literature. Our findings confirm ed the association between recurrent, persistent or chronic sinusitis, and ipsilateral septal ridges or spurs (33%), unusual ipsilateral def lexions of uncinate process (31%), and contralateral septal watch glas s like deviation (42%). We found no correlation for the other studied variants (concha bullosa, paradoxical curve of middle turbinate, pneum atised uncinate process, hypertrophic ethmoid bulla, Haller cell and a ccessory maxillary ostium).
