Effect of Perioral muscle training in obstructive sleep apnea outpatients 

Objective: The lips play an important role in daily life. Reduced lip closure function can adversely affect oral function. Weak lip closure force (LCF) is associated with low tongue up power (TUP). The hyoid bone supports the tongue and allows a wide range of tongue movements. We hypothesize that perioral muscle training would increase LCF, TUP and raise the position of hyoid bone (HYP). Therefore, we implemented a lip training program to determine the impact of a two-month perioral muscle training on LCF, TUP and the position of HYP in patients with the obstructive sleep apnea syndrome (OSAS).

Method: 22 OSAS outpatients, being treated with oral appliances at NUSDM Hospital, were recruited for this study. The patients were randomly allocated to perioral muscle training with the Patakara lip training device (Patakara Co. Pty. Ltd.) (PTR group), or no training (control group). Subjects underwent three 3-min sessions of lip training daily for 2 months with the Patakara. The hyoid bone position of each patient was objectively evaluated based on X-rays taken at initial medical examination and 2 months post-lip training. This study was approved by the Ethics Committee of Nihon University School of Dentistry at Matsudo (EC 10-023).

Result: Lip training significantly increased LCF and TUP in the PTR compared to the control group (p<0.05). Radiographic findings revealed a significant reduction in the vertical distance measured perpendicular to the Frankfort horizontal plane from the hyoid bone in the PTR group (p<0.05).

Conclusion: The present findings showed that daily perioral muscle training not only improved the strength of the orbicularis oris muscle but also that of the suprahyoid muscles, thereby raising the HYP and helping to restore the balance between lip and tongue functions. These findings have important clinical implications for treatment of obstructive sleep apnea.
