To investigate the effect of nasal septum deviation, without obstructive sleep apnea, on sleep quality.


The present case-controlled study enrolled patients older than 16 years with nasal septum deviation who attended the Otorhinolaryngology Clinic between December 2013 and July 2014. The control group was selected from patients attending the clinic for another complaint. Sleep quality was evaluated via the Pittsburgh Sleep Quality Index, and differences between the groups were compared using the Mann–Whitney U test.


During the study period, 55 patients with nasal septum deviation were included in the study group, and the control group consisted of 51 patients with no complaints of nasal obstruction. Compared with the control group, patients with nasal septum deviation were found to be significantly higher (P <0.05) in all parameters of Pittsburgh Sleep Quality Index.


The presence of nasal septum deviation with nasal obstruction should be investigated in patients with sleep disorders. If any pathology is present, opening the nasal passages should be ensured and sleep disorders reevaluated.
