Clinical analysis of pharyngeal musculature and genioglossus exercising to treat obstructive sleep apnea and hypopnea syndrome

摘要

Objective: To evaluate the effect of pharyngeal musculature and genioglossus exercising on obstructive sleep apnea and hypopnea syndrome (OSAHS). Methods: We conducted a non-randomized retrospective clinical trial of 75 patients with OSAHS. Fifty-four patients were managed by exercising of the pharyngeal musculature and genioglossus (exercising group). Twenty-one patients, who refused to undertake any treatment, were defined as the control group. We took the Epworth Sleepiness Scale (ESS), checked patients’ polysomnography, and took 320-detector computed tomography (CT) before treatment. Six and twelve months later, we made records of apnea hypopnea index (AHI), lowest arterial oxygen saturation (LSaO2), body mass index (BMI), the shortest sagittal diameter, and transverse diameter, and the effective rates of exercising were calculated and compared with the 21 patients without any treatment (control group) at the same time. SPSS 10.0 was used to analyze the data. Results: Before treatment, the ESS value was 7.67; 6 and 12 months later, the values were 3.54 and 3.25, respectively in the exercising group. AHI was decreased to 15.36 after 6 months and 13.79 after 12 months from 22.84 at the beginning. LSaO2 values were up to 81.18 after 6 months and 81.93 after 12 months from 74.05 at the beginning. There were significant differences in ESS scores, AHI, and LSaO2 between pre-treatment and post-treatment in the exercising group (P0.05). At 12 months of exercising, the compliance of the anteroposterior pharyngeal wall of the retropalatal area was lower (P<0.01) than that before treatment. There was no significant change of BMI in either group. Conclusions: Exercising pharyngeal musculature and genioglossus is a kind of non-invasive and cost-effective method to treat some OSAHS patients, especially those who are old, without surgical complications, and especially mild and moderate OSAHS patients who do not want to take surgery and continuous positive airway pressure (CPAP) treatment. In addition, exercising pharyngeal musculature and genioglossus can be considered as remedial treatment of OSAHS to surgery and other therapies.
