Abstract

A prosthesis for insertion in an ear to reduce pain resulting from TMJ disorders. The ear insert has a predefined shape conforming to the shape of the ear canal when the jaw is in an open position. The ear insert supports the TMJ and associated secondary musculature to reduce strain in the TMJ area, including the muscles, ligaments, nerves, and the temporo-mandibular joint itself. The insert is hollow in the inside to permit hearing and is made of a rigid material which retains the shape of the ear canal. A scalloped indenture extends across a surface of the ear insert positioned behind the tragus.

Claims

1. A prosthesis adapted to be inserted into an ear canal in an ear having a tragus for treating discomfort in a joint between a mandible and a corresponding temporal bone, wherein the ear canal includes an isthmus, the prosthesis comprising:

a substantially rigid and incompressible structural body adapted to conform to a contour of an interior surface of a portion of the ear canal which extends between an entrance to the ear canal and the isthmus when the joint is in an open position,

wherein said structural body is hollow along its length,

the structural body including a proximal base portion adapted for positioning adjacent the entrance of the ear canal, the structural body further including a distal end portion adapted to extend an effective distance into the ear canal to treat discomfort in the joint,

wherein a scalloped indenture is cut out from the structural body and extends away from a boundary edge of the proximal base portion across a surface of the structural body and is adapted for positioning behind the tragus of the ear.

2. The prosthesis as recited in claim 1, wherein said structural body is formed from acrylic.

3. The prosthesis as recited in claim 1, further including at least one post element projecting away from the proximal base portion, the post element adapted to extend to a position outside of the ear canal when the prosthesis is inserted within the ear canal.

4. The prosthesis as recited in claim 3, wherein said post element is formed from a thermoplastic polymeric or non-polymeric material.

5. The prosthesis as recited in claim 4, wherein said post element is formed from monofilament nylon.

6. The prosthesis of claim 1, further comprising at least one compressible, cushioning layer around at least a portion of said structural body.

7. The prosthesis of claim 1, wherein said proximal base portion has a greater diameter than said distal end portion.

8. The prosthesis of claim 1, wherein said prosthesis is configured to be held in nested relation relative to the interior surface of the ear canal.

9. The prosthesis of claim 1, wherein said scalloped indenture has a length and width suitable to accept and surround the tragus thereby facilitating a bending inwardly of the tragus towards the entrance of the ear canal without obstruction.

10. The prosthesis of claim 1, wherein said proximal base portion includes a peninsular leg adapted to project downwardly.

11. A method of treating discomfort in a joint between a mandible and a corresponding temporal bone, the method comprising:

inserting the prosthesis of claim 1 into an ear canal in an ear having a tragus,

wherein the ear canal includes an isthmus.

12. The method as recited in claim 11, wherein the structural body is free from any covering.

13. The method as recited in claim 11, wherein said structural body is formed from acrylic.

14. The method as recited in claim 11, wherein said scalloped indenture is characterized by a length and width sufficient to accept and surround the tragus of the ear.

15. The method as recited in claim 11, wherein the prosthesis further includes at least one post element projecting away from the proximal base portion, the post element extending to a position outside of the ear canal when the prosthesis is inserted within the ear canal.

16. The method as recited in claim 15, wherein said post element is formed from a thermoplastic polymeric material.

17. The method as recited in claim 16, wherein said post element is formed from monofilament nylon.

18. The method as recited in claim 11, wherein the proximal base portion further includes an extended peninsular leg portion adapted to extend into an inter-tragal notch.

19. The method as recited in claim 18, wherein the prosthesis further includes at least one post element projecting away from the extended leg portion, the post element extending to a position outside of the ear canal when the prosthesis is inserted within the ear canal.
