Claims
- 1. A method for stiffening a preselected region of soft palate tissue comprising epithelial tissue supported by subepithelial tissue in a mammal, the method comprising the steps of:
- (a) cooling an exposed surface of epithelial tissue in the preselected region of soft palate tissue; and
- (b) applying energy to the preselected region of the soft palate tissue to induce thermal injury of the subepithelial tissue in the preselected region, wherein the thermal injury of the subepithelial tissue results in stiffening of the preselected region of the soft palate tissue.
- 2. The method of claim 1 wherein cooling step (a) is contemporaneous with inducing thermal injury of the subepithelial tissue.
- 3. The method of claim 1 wherein cooling step (a) is prior to inducing thermal injury of the subepithelial tissue.
- 4. The method of claim 2 wherein cooling step (a) is prior to inducing thermal injury of the subepithelial tissue.
- 5. The method of claim 1, wherein in step (b) the thermal injury of the subepithelial tissue induces fibrosis in the subepithelial tissue.
- 6. The method of claim 1, wherein in step (b) the thermal injury of the subepithelial tissue induces shrinkage of the preselected region of the soft palate tissue.
- 7. The method of claim 1, wherein in step (b) the stiffening of the preselected region of the soft palate tissue reduces snoring in the mammal.
- 8. The method of claim 1, wherein in step (a) the energy is provided by laser light, incoherent light, microwaves, ultrasound or RF current.
- 9. The method of claim 1 wherein in step (a) the energy is provided by laser light.
- 10. The method of claim 1, wherein the mammal is a human.
- 11. A non-invasive method for stiffening a preselected region of soft palate tissue comprising epithelial tissue supported by subepithelial tissue in a mammal, the method comprising the steps of:
- (a) providing a radiation beaen having a wavelength in the range from about 0.6 to about 1.8 microns and either a fluence in the range from about 5 to about 500 joules per square cm or a power density in the range from about 1 to about 100 watts per square cm;
- (b) cooling an exposed surface of epithelial tissue in the preselected region of soft palate tissue; and
- (c) applying the beam to the preselected region of the soft palate tissue to induce thermal injury of the subepithelial tissue in the preselected region, wherein the thermal injury of the subepithelial tissue results in stiffening of the preselected region of the soft palate tissue.
- 12. The method of claim 11, wherein in step (a) the wavelength is about 1.5 microns.
- 13. The method of claim 11 wherein cooling step (b) is contemporaneous with inducing thermal injury of the subepithelial tissue.
- 14. The method of claim 11 wherein cooling step (b) is prior to inducing thermal injury of the subepithelial tissue.
- 15. The method of claim 13 wherein cooling step (b) is prior to inducing thermal injury of the subepithelial tissue.
- 16. The method of claim 11, wherein in step (c) the thermal injury of the subepithelial tissue induces fibrosis in the subepithelial tissue.
- 17. The method of claim 11, wherein in step (c) the thermal injury of the subepithelial tissue induces shrinkage of the preselected region of the soft palate tissue.
- 18. The method of claim 11, wherein in step (c) the stiffening of the preselected region of the soft palate tissue reduces snoring in the mammal.
- 19. The method of claim 11 comprising the additional step of providing a radiation absorbing material to the subepithelial tissue in the preselected region prior to application of the beam of radiation.
- 20. The method of claim 11, wherein the mammal is a human.
