Introduction: Sinonasal polyposis (SNP) is a chronic inflammatory dise.se.of the.mucosa of the.nasal cavitie. and facial sinuse.. It is characte.ize. by an oe.e.atous, multifocal and bilate.al de.e.e.ation of the.nasosinus mucosa, which originate. in the.late.al masse. of the.e.hmoid, whe.e.it cause. the.formation of smooth, ge.atinous, transluce.t and pyriform polyp le.ions. The.obje.tive.of this study was to re.ie. e.ide.iological, clinical, paraclinical data and e.aluate.the.re.ults of e.doscopic surgical tre.tme.t. Patie.ts and Me.hods: This is a re.rospe.tive.study on 60 patie.ts followe. at the.e.T de.artme.t of the.Fann National Unive.sity Hospital Ce.te., from January 2010 to De.e.be. 2015. All patie.ts with sinonasal polyposis we.e.include. in the.study. Re.ults: The.ave.age.age.of our patie.ts was 38 ye.rs and the.se. ratio (M/F) was 0.8. In the.patie.ts’ historie., we.found 18% asthma and 10% Widal’s dise.se. The.ave.age.consultation time.was 8.5 ye.rs. All patie.ts had consulte. for nasal obstruction;rhinorrhe. was bilate.al and found in 67.7% of case., with olfactory disorde.s accounting for 50%. The.CT scan pe.forme. in 58% of case. made.it possible.to spe.ify the.e.te.t of the.le.ions;the.involve.e.t of the.e.hmoidal sinus was constant and e.te.de. to the.othe. sinuse. e.ce.t in 2 case.. All patie.ts had re.e.ve. me.ical tre.tme.t with local corticoste.oids. e.doscopic surgical tre.tme.t was initiate. in 43% of case. afte. failure.of corticoste.oid-base. me.ical tre.tme.t.
