Abstract：

Since sleep disordered breathing (SDB) is a multifactorial disease, it’s hard to find a universal treatment for all patients. Therefore, combining different treatments might be a good strategy. In order to develop possible combination strategies, we have to investigate the mechanisms, advantages, and limitations of different treatment modalities. Regarding to the mandible advancing device (MAD): 1.MAD can widen the lateral pharyngeal walls of the upper airway. But its effects are often compromised in obese patients or patients needs high CPAP pressure. 2.The tongue won’t be necessarily pulled forwards within the MAD. However, with certain designs, the MAD might be able to assist in supporting the tongue. 3.For patients with small tongue volume and low level of hyoid bone, the behaviors of the tongue within the MAD is hard to predict. Thus, the MAD might play certain roles in combining with other treatments: 1.We have demonstrated the combination of MAD and CPAP can effectively lower the CPAP pressure. 2.For MAD users with residual snoring, MAD might prevent/delay the relapse of soft tissue surgeries. 3.Combing MAD and tongue-suspension surgery might be helpful in treating SDB patients with small and low-positioned tongue.
