A method for treating obstructive sleep disorders includes accessing the interior of the tongue through a sublingual incision; advancing an instrument through the incision into the interior of the tongue; and instantaneously removing an amount of tissue from the interior of the base of the tongue with the instrument. The present invention includes forming a cavity or plurality of channels in the tongue. The cavity may be collapsed using a suture, fastener or bioadhesive. An emplaced suture may be provided to hold the cavity in a collapsed position thereby reducing the degree of obstruction. Additionally, thermal energy may be applied to the tissue surface immediately surrounding the channels to cause thermal damage to the tissue surface, thereby creating hemostasis and stiffening the surrounding tissue structure.

Embodiments of the invention include methods and devices to prevent or treat upper airway disorders in mammals related to impaired airflow. One aspect of this invention is a tongue retractor (LTR) that indirectly retracts tongue base by its implant site in the frenulum area. This simplifies the insertion, adjustment and maintenance of the device. Another aspect of this invention describes a highly localized and fully implantable LTR that is inserted into the base of tongue to stiffen lax surface mucosa or mechanically couple it to internal tongue structures. Another aspect of this invention is an LTR inserted in or around the pharyngoglossal fold. This site allows retraction and stiffening of tongue base tissue as well as the soft palate and lateral pharyngeal wall.

A patient's obstructive sleep apnea is treated by identifying a patient with sleep apnea attributable at least in part to movement of a base of a tongue of the patient toward a pharyngeal wall of the patient. The tongue is stiffened by an implant sized to be placed within the tongue. A distal portion of the implant is sized to extend within the tongue from a first end near a mandibular-geniohyoid interface to a second end near a base of the tongue. A proximal portion is attached to the first end and adapted to be secured to a jaw bone of the patient following a period of healing after placement of the implant in the tongue.

An adjustable soft palate support and an implantation method are provided. The adjustable soft palate support is a flat implant made of a material capable of being implanted into a human body for a long term, including a hard palate connecting end and a support. The support is a flat implant capable of being inserted into a soft palate, and is connected to the hard palate connecting end.
