All of the patients' age, gender, comorbid chronic disease, complaints, preliminary diagnosis and PSG diagnosis were evaluated retrospectively.Results: In our study, the average age of patients was 56 and 43% women 57% were male. Complaints of patients were snoring, fatigue, stopped breath during sleep, insomnia, headache, daytime sleepiness, restless legs and abnormal behaviors during sleep.
