Devices and methods for reshaping cartilage structures
Described are methods of reshaping a cartilage structure. One such method comprises creating a virtual three dimensional image of the cartilage structure; manipulating the virtual three dimensional image of the cartilage structure so as to obtain a virtual three dimensional image of a desired final shape of the cartilage structure; creating a virtual prototype of a device to hold the cartilage structure in the desired final shape of the cartilage structure; manufacturing the device; lasing the cartilage structure; and fitting the manufactured device to the cartilage structure (e.g., ear).
1. A method of shaping a subject's ear to a desired final shape and/or position, the method comprising:
lasing the subject's ear so as to stimulate chondrogenesis in the ear;
fitting to the subject's lased ear an integral device comprising:
a first surface configured to fit against and be adhered to the subject's head behind the lased ear, and
a second surface configured to retain the lased ear in a desired final shape and/or position;
wherein, upon fitting of the integral device onto the subject's head and lased ear, the lased ear is maintained in the desired shape and/or position with respect to the subject's head; and
maintaining the integral device on the lased ear until the ear is reshaped to the desired final shape and/or position.
2. A method of urging an ear of a subject from its natural shape and/or position toward a desired final shape and/or position, the method comprising:
lasing the ear so as to stimulate chondrogenesis in the ear;
adhering to the subject's head a device comprising:
a portion of a first member configured for disposition between the lased ear and the subject's head; and
a second member configured for disposition on the opposite side of the ear from the first member to sandwich the ear, wherein the first member and the second member are structured in harmony to deform the lased ear from its natural shape and/or position toward the desired final shape and/or position; and
maintaining the device on the lased ear until the shape and/or position of the ear is permanently changed.
3. The method according to claim 2 , wherein:
the device is an integral device.
4. The method according to claim 2 , wherein:
the first member is structured to facilitate bending a free-standing cantilevered ear flap portion of the ear effective to displace a rear portion of the helix of the ear flap to a position that is closer to the subject's head.
5. The method according to claim 4 , wherein:
the first member is structured in harmony with the second element to bend the ear flap.
6. The method according to claim 2 , wherein:
upon fitting of the device onto the lased ear, the lased ear is urged toward the desired final shape and/or position with respect to the subject's head.
7. The method according to claim 2 , wherein:
the device is maintained in an installed position for a first period of substantially continuous time comprising about three weeks.
8. The method according to claim 7 , wherein:
the device is subsequently maintained in an installed position only overnight for a second period of time comprising about two weeks.
9. The method according to claim 4 , wherein:
the first member comprises a first surface configured to fit against and be adhered to the subject's head, and further comprising:
adhering the first surface to the head.
10. The method according to claim 9 , wherein:
the first member comprises a second surface configured to fit against and be adhered to a portion of the medial surface of the ear flap; and further comprising:
adhering the second surface to the ear flap.
11. The method according to claim 9 , wherein:
the first surface comprises a portion disposed in the space between the medial surface of the ear flap and skin of the head.
12. The method according to claim 9 , wherein:
the first member is structured to apply tension to a portion of the medial surface of the ear flap.
13. The method according to claim 9 , wherein:
the first member is structured to apply tension to the second element effective to displace the ear flap toward the head.
14. A method of urging an ear of a subject from its natural shape and/or position toward a desired final shape and/or position, the method comprising:
lasing the ear so as to stimulate chondrogenesis in the ear;
positioning a device on the subject's head, the device comprising:
a first member structured to facilitate bending a free-standing cantilevered ear flap portion of the ear effective to displace a posterior portion of the helix of the ear flap to a position that is closer to the subject's head, a portion of the first member being configured for disposition behind the ear and in the space between the medial surface of the ear flap and skin of the head; and
maintaining the device on the lased ear until the shape and/or position of the ear is permanently changed.
15. The method according to claim 14 , wherein:
the first member comprises a first surface configured to fit against and be adhered to the subject's head and a second surface configured to fit against and be adhered to a portion of the medial surface of the ear flap; the method further comprising:
adhering the first surface to the head and the second surface to the ear flap.
16. The method according to claim 14 , wherein the device further comprises:
a second member configured for disposition on the opposite side of the ear from the first member to sandwich the ear, wherein the first member and the second member are structured in harmony to deform the lased ear from its natural shape and/or position toward the desired final shape and/or position; the method further comprising:
adhering the first surface to the head.
17. The method according to claim 16 , wherein:
installing the device in operable registration with respect to the ear causes the first member to apply a pulling force to the second member, and the second member consequently applies a pushing force on a portion of the lateral surface of the ear flap effective to bend the ear flap and displace a rear portion of the helix toward the head.
18. The method according to claim 14 , wherein:
the device is maintained in an installed position for a first period of substantially continuous time comprising about three weeks.
19. The method according to claim 18 , wherein:
the device is subsequently maintained in an installed position only overnight for a second period of time comprising about two weeks.
