    • A method of tongue reduction by thermal ablation using high intensity focused ultrasound includes the steps of introducing an ultrasound emitting member in a patient's oral cavity, positioning the ultrasound emitting member adjacent an external surface of the tongue, emitting ultrasound energy from the ultrasound emitting member into the tissue of the tongue, focusing the ultrasound energy in the tongue, ablating the tissue of the tongue with the focused ultrasound energy to form an ablated tissue area below the external surface of the tongue containing unablated tissue of the tongue and a plurality of lesions at which the tissue of the tongue is ablated, and withdrawing the ultrasound emitting member from the oral cavity. The lesions are allowed to be absorbed by the patient's body and/or to remain as altered tissue such that the tongue is reduced in size to correspondingly increase the size of the patient's airway and/or is stiffened to resist vibration. The lesions preferably begin a predetermined distance below the external surface of the tongue such that the mucosa remains undamaged and preserved.
    • 通过使用高强度聚焦超声波的热消融来减少舌头的方法包括以下步骤:在患者的口腔内引入超声发射部件,将超声发射部件邻近舌的外表面定位,从超声发射部件发射超声波能量 舌头的组织将超声能量聚焦在舌头中,用聚焦超声能量消融舌头的组织,以在舌头的外表面下方形成消融的组织区域,该组织区域包含舌头的未经消融的组织和多个病变 其中舌部的组织被烧蚀,并且从超声发射部件从口腔抽出。 允许病变被患者的身体吸收和/或保持为改变的组织,使得舌头尺寸减小以相应地增加患者气道的尺寸和/或被加强以抵抗振动。 病变优选在舌头的外表面下方开始预定距离,使得粘膜保持未损伤并保持。
