ABSTRACT
OBJECTIVE:
To explore the efficacies of nasal cavity enlarging surgery in obstructive sleep apnea hypopnea syndrome (OSAHS) patients with nasal obstruction.METHODS:
From April 2011 to October 2012, a total of 22 OSAHS patient with nasal obstruction underwent nasal cavity enlargement. Natural overnight snoring was digitally recorded, polysomnography (PSG) performed simultaneously and nasal resistance measured at pre- and post-operation. Body mass index (BMI), Epworth sleepiness scale (ESS), apnea-hypopnea index (AHI), minimum oxygen saturation SaO2, total nasal resistance, peak frequency, maximal frequency, mean frequency, central frequency and power ratio 800 Hz of snores were recorded and compared.RESULTS:
BMI and SaO2 rose while AHI and ESS declined post-operatively. No statistical difference existed between pre-operation and post-operation. The total nasal resistance was (0.39 ± 0.15) and (0.29 ± 0.11) Pa·cm(-3)·s(-1) at pre- and post-operation. And there was significant statistical difference (P < 0.01) . The snores at pre- and post-operation exhibited different patterns in time and power spectrum distribution domains. And fmax, fpeak and fmean declined while fc and PR800 rose at post-operation. Significant statistical differences existed in the change of fpeak and PR800 at pre- and post-operation (P < 0.01) .CONCLUSION:
Nasal cavity enlargement can lessen nasal resistance and change the acoustic characteristics of snoring in OSAHS patients. The postoperative snoring focus of lower frequency suggests that acoustic parameters of snores may be used to evaluate the efficacy of OSAHS surgery.
