Abstract:
Objective:To observe the efficacy of nasal cavity expansion surgery in the treatment of nasal obstruction complicated with obstructive sleep apnea hypopnea syndrome(OSAHS),and explore the effects of nasal structure change on sleep quality and nasal resistance in patients with OSAHS.
Methods:The visual analogue scale score for nasal congestion,Pittsburgh sleep quality index(PSQI) scale,Epworth sleepiness scale(ESS),polysomnography(PSG) map and nasal airway resistance in 99 patients with snoring complicated with nasal obstruction were examined before 3 days of operation.The patients were divided into the mild OSAHS group(
n=48),moderate OSAHS group(
n=43) and severe OSAHS group(
n=8) according to the apnea hypopnea index(AHI) and lowest oxygen saturation(LSaO
2).All patients were treated with nasal endoscopic expansion,and followed up for 6 months.The index changes between before and after operation among three groups were compared.
Results:Before and after operation,the nasal resistance and AHI in mild and moderate OSAHS groups were significantly lower than those in severe OSAHS group,which in mild OSAHS group was significantly lower than that in moderate OSAHS group(
P<0.01),and the LSaO
2 in mild OSAHS group was higher than that in moderate and severe OSAHS groups(
P<0.05 to
P<0.01).Before operation,the ESS score in mild and moderate OSAHS groups were significantly lower than that in severe OSAHS group(
P<0.01),and the difference of the ESS score among three groups was not statistically significant after operation(
P>0.05).The difference of the PSQI score among three groups before and after operation was not statistically significant after operation(
P>0.05).Compared with before operation,the scores of the nasal resistance and ESS in three groups significantly decreased after operation(
P<0.01).
Conclusions:Nasal cavity expansion surgery can significantly decrease the nasal airway resistance,improve the symptom of sleepiness in patients with mild or moderate OSAHS,and improve the LSaO
2 of patients with severe OSAHS.
