Internal laryngeal muscle injection tool

A method for surgically preparing a subject in need thereof to receive injections into internal laryngeal muscles in said subject, comprising:

• providing a device for guiding injections into internal laryngeal muscles, comprising:
• a silicone body with external and internal surfaces;
• pairs of spaced apart fixation blades extending from opposite sides of the silicone body, wherein the pairs of spaced apart fixation blades are configured to affix the silicone body to thyroid cartilage of a subject with portions thyroid cartilage passing between the pairs of spaced apart fixation blades;
• at least one guide channel extending from the external face to the internal face of the silicone body, wherein the at least one guide channel comprises a plurality of guide channels;
• and
• implanting the device in an anterior site in the throat of the subject such that a first of the plurality of guide channels is in alignment with a first selected internal laryngeal muscle area such that multiple injections may be delivered to the first selected internal laryngeal muscle area through the first of the plurality of guide channels, and such that a second of the plurality of guide channels is in alignment with a second selected internal laryngeal muscle area different from and spaced apart from the first selected internal laryngeal muscle area such that multiple injections may be delivered to the second selected internal laryngeal muscle area through the second of the plurality of guide channels.
