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 and an inter-tragal notch 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 hollow substantially rigid and incompressible structural body having a predefined shape adapted to substantially conform to a contour of a portion of the ear canal which extends approximately between an entrance to the ear canal and the isthmus when the joint between the mandible and the corresponding temporal bone is in an open position,

the structural body including a proximal base portion adapted for positioning adjacent the entrance of the ear canal,

wherein the proximal base portion includes an extended peninsular leg portion adapted to extend substantially to the inter-tragal notch, the structural body further including a distal end portion adapted to extend an effective distance into the ear canal,

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 towards said distal end portion,

wherein said scalloped indenture is adapted for positioning behind the tragus of the ear,

and at least one post element projecting away from the peninsular leg portion, the post element adapted to extend to a position outside of the ear canal when the prosthesis is inserted within the ear canal.

2. The prosthesis as recited in claim 1, wherein said scalloped indenture is characterized by a length and width sufficient to accept the tragus of the ear.

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

4. The prosthesis as recited in claim 1, wherein said post element is formed from a thermoplastic polymeric or non-polymeric material.

5. The prosthesis as recited in claim 1, wherein said post element is formed from monofilament nylon.

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

inserting a prosthesis into an ear canal in an ear having a tragus and an inter-tragal notch,

wherein the ear canal includes an isthmus,

wherein the prosthesis comprises a hollow substantially rigid and incompressible structural body having a predefined shape adapted to substantially conform to a contour of a portion of the ear canal which extends approximately between an entrance to the ear canal and the isthmus when the joint between the mandible and the corresponding temporal bone, is in an open position,

the structural body including a proximal base portion positioned substantially 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, wherein the proximal base portion is of greater diameter than the distal end portion,

wherein the proximal base portion includes a single extended peninsular leg portion adapted to extend downwardly into the inter-tragal notch when said prosthesis is inserted into the ear canal,

a scalloped indenture cut out from the structural body and extending away from a boundary edge of the proximal base portion across a surface of the structural body towards said distal end portion,

wherein the scalloped indenture is positioned behind the tragus of the ear, and

at least one post element projects 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.

7. The method as recited in claim 6, wherein the structural body is free from any covering.

8. The method as recited in claim 6, wherein said structural body is formed from acrylic.

9. The method as recited in claim 6, wherein said scalloped indenture is characterized by a length and width sufficient to accept the tragus of the ear.

10. The method as recited in claim 6, wherein said post element is formed from a thermoplastic polymeric material.

11. The method as recited in claim 10, wherein said post element is formed from monofilament nylon.

12. The method as recited in claim 6, wherein at least one post element projects away from the extended leg portion.
