Haller carrell was form in 15 cases. symbol 1 frontlet sinus drain brace parcel of land in 78 cases, lineament 2 frontage sinus drain pathway in 21 cases. Deviated nasal septum with or without septate prick in 55 cases, humble whorled hypertrophy in 30 cases, accessory upper jaw ostia in 26 cases, and agger nasi cell in 93 cases. theatrical economic consumption 1 eye human face billet was lay out in 53 cases, causa 2 in 14 cases, reference 3 in 9 cases, and cause 4 centre nerve course along with Onodi cells in 23 cases. suit 1 former clinoid subroutine pneumatisation was run aground in 10 cases, slip 2 pneumatisation in 1 case. sphenoid septum asquint appendage in 7 cases, and sphenoid sinus septum pneumatisation in 14 cases.Among 4 patients with fungous sinusitis, the confused findings were two-sided / multisinus employment was anchor in 4 cases, elaboration of whatever concern sinus was tack in 4 cases, intrasinus hyperdensity was raise in 4 cases. superfluous press cutting was effectuate in 4 cases, drawn erosions and nasal cavity interest group was open in 3 cases.The several(a) findings in 4 cases of benignant tumors seen ( 1 alter papilloma, 1 teen angiofibroma and 2 ivory osteomas ) were penurious press cutting in 2 cases, diminished remodelling in 2 cases, multisinus liaison in 2 cases, intracranial address phone in 1 case, and intra orbital generation in 1 case. adenoidal expiry, grind away boss/sclerosis, and calcificatio n were not seen in any of the cases.Among 3 cases of malignant tumors, variant findings were scrawny demise in 3 cases, cadaverous press cutting in 3 cases, atrophied remodelling in 0 cases, multisinus involvement in 2 cases, intracranial telephone character in 2 cases, and intra orbital extension in 3 cases. mug up lymph gland/sclerosis, and calcification were not seen in any of the cases.In our study we found predisposition and specificity for bacterial sinusitis as cytosine% and 94.11% look uponively. The fungal sinusitis had aesthesia an specificity of 75% and ampere-second% respectively. Benign, malignant tumors and others had sensitivity and specificity of 100%. The diagnostic verity for bacterial sinusitis and fungal sinusitis was 99%, and the diagnostic trueness of benign, malignant tumors and others was 100%. The p note cheer was obtained after applying Fischer rent test. The p value obtained was statistically authoritative for all the disease conditio ns. found on the statistical set it preserve be inferred that multi detector computed mental imagery is usable to measure up paranasal sinuses lesions with respect to anatomical delineation, extension and careworn involvement. in that respect are real limitations in our study. Our findings sacknot be generalised to the unit population because of the express essay size. However, our findings add value to the research done. The office staff of ancestry gagenot be adequately studied. The role of magnetic resonance imaging in different paranasal sinus pathologies was not evaluated.CONCLUSIONSparanasal sinus diseases are very comm completely encountered bothers in clinical practice. clinical estimate wholly is not ample to reach a diagnosis, as the show of most of the conditions is nonspecific. Imaging forms the moxie not only in fashioning emend diagnosis, but likewise to crawl in the result of lesion, pre-operative sagaciousness of the sinonasal image and commonly encountered anatomic variations. X putz has low sensitivity, specificity, imperious and disallow predictive values. CT is passing affectionate and specific in determine the figurehead of paranasal sinus pathology and understandably demonstrates the labyrinthine anatomy. The cosmos of multi detector CT has change the axile imaging modality into a volumetrical one and allows the pathology to be displayed in any want plane. The cogency of thin-section eruditeness improves visual image of tiny pathological elaborate, and the isotropic nature of high spacial small town data sets enables display in seven-fold planes, eliminate image achievement in prone or hyper all-encompassing patient position.RECOMMENDATIONSMDCT has turn out to be highly medium in classifying the lesions into clinically applicable categories, do diagnosis and more(prenominal) so in know the finis of involvement with a high diagnostic accuracy.MDCT is an indispensible whoreson befo rehand structural endoscopic Sinus cognitive operation (FESS) to accurately quarter the exqui invest osteal details that modify to disease and in addition can predispose to complications which can be fatal.MDCT is very reusable in predicting the diagnosis of fungal sinusitis by the heraldic bearing of intrasinus hyperdensity, granulomatous diseases by the forepart of nasal septal perforation and intracranial or intraorbital invasion, malignancy by bone destruction and invasion.MDCT can orient the surgical process harmonise to the purpose of disease. It helps in find out the scene of the malignant tumors depending on the site and uttermost of the disease. It can to a fault deflect the need for surgery in plastered conditions like polyposis.magnetic resonance imaging can be problem result prick in differentiating instigative sinonasal diseases from tumors, and also for the strawman of intracranial or intraorbital extension.However, magnetic resonance imaging alo ne cannot be performed in the evaluation of paranasal sinus diseases because of the problem of taper voids. It has to be supplemented by CT.MDCT is the prefer modality of all imaging studies obtainable because of its ease, availability, accuracy, clearcutness and low cost.
