1. A method of treating obstructive sleep apnea, comprising:
providing an implant device comprising:
a substantially planar central body portion having a top side and a bottom side;
at least two adjustable wing portions; and
at least two connecting members, each one of the at least two connecting members extending from opposite sides of the central body portion, the each one of the at least two connecting members being configured for flexibly connecting each one of the at least two wing portions at opposite sides to said central body portion;
forming a surgical opening to expose a genioglossus muscle;
exposing a branch of a hypoglossal nerve for stimulation by the implant at least on one side of the genioglossus muscle of a patient;
forming at least one pocket on at least one side of the genioglossus muscle such that dimensions of the at least one pocket are configured to fit the at least one of the at least two wing portions of the implant device;
inserting the implant device through the surgical opening such that the central body extends over the genioglossus muscle and each one of the wing portions is received in the respective at least one pocket;
positioning the implant device based on a determination of a relative amount of stimulation potential for both a styloglossus nerve and the hypoglossal nerve by the implant device; and
securing the implant device to the muscle.
