Deviated Nasal Septum and Inferior Turbinate Hypertrophy: Are They the Independent Cause of Sleep-Related Breathing Disorders?

Background and Objectives Nasal obstruction has been assumed to be correlated with sleep-related breathing disorder (SRBD). However, a definite correlation between nasal SRBD is still controversial. This study aimed define whether symptoms severity of the deviated septum nose (DSN) inferior turbinate hypertrophy (ITH) are SRBD. Subjects Method retrospective 60 patients’ preoperative polysomnography who have undergone septoplasty turbinoplasty. Patients obesity, tonsillar hypertrophy, high Mallampati class, mandibular problem, polyp or concha bullosa were excluded from analysis. Subjective scores, DSN/ITH grades collected, correlations apnea-hypopnea index (AHI), lowest oxygen saturation, snoring time analyzed. Results The average AHI, saturation relative 3.72±5.79, 89.78%±6.81%, 8.45%±10.43%, respectively. number patients normal, obstructive sleep apnea (OSA) syndrome mild, moderate, severe 49 (82%), 6 (10%), 4 (7%) 1 (1%), degrees DSN ITH, subjective congestion scores showed no significant polysomnographic results. Age AHI had coefficient 0.54 (p<0.001) increased increasing age. Multiple linear regression demonstrated that age (regression 0.229, 95% confidence interval 0.135 0.322, p<0.001) was significantly associated while other variables statistically association (p>0.05). Conclusion Septal deviation unlikely cause OSA/snoring independently without causes Key words: ㆍ Polysomnography Sleep syndromes Snoring
