| Age | 46,78±9,66 | 50,90±10,96 | <0,001 |
| BMI | 29,39±3,80 | 33,30±6,45 | <0,001 |
| Neck circumflex | 42,25 ± 2,63 | 43,49 ± 2,58 | 0,001 |

Aim: We aimed to compare clinical, polysomnographicparametresofpatientswithpositional andnonpositionalOSA
Material and method: This retrospective study was conducted during January2017andSeptember2018inatertiarycarecenterIstanbul. Acompleterecordof310patientswhowerepresented to our sleep center andunderwent polysomnography (PSG) was performed.30ofthesepatientswereexcluded becauseofcongestiveheart failure, chroniclungdiseaseandcentralsleepapneapatientsweredividedintotwo groups according toPSGaspositionalOSApatients(group1)andnonpositionalOSApatients(group2)Age, gender, BMI, neckcircumflex, polysomnographicparametreswereevaluated.
Results: Atotalof280 patientsmadeupof102women and 178menwereincludedinthisstudy. Themeanageof group1(46,78±9,66) was found to be significantly lower than the mean age of group2(50,90±10,96)(p<0,001)The meanbodymassindexandneckcircumflexof group1werelowerthanthoseofgroup2(p<0,001)Sleeptime, Sleepefficiency(%)minimumoxygensaturation, meanoxygensaturation of group1wassignificantlyhigherthan those of group2. AHI, AI, ODI, TST%90, heart rate and PLM index of group1 were lower than group2. The rate of sleep apnea severity in group1(7.95%)waslowerthan in group2(53.65%).
