A device introduced by injection into the nose, allowing for structural support or filling of defects in the nose, and causing a change in external shape of the nose. The device and inserts and implants described also have use in cosmetic applications relating to the facial tissue. ## Claims ### Claim 1 A method for changing a structure of a nose, the method comprising: placing an implant within a cylindrical core of an introducing needle, the implant having a length, a width and a thickness sized for the implant to reside within nasal tissue of the nose;

guiding the implant to a desired location within the nasal tissue using the sutures extending from each of the first and second end of the implant. ### Claim 10 (depends on 1) The method according to claim 1, wherein the placing step is for treatment of nasal or paranasal tissues of the patient. ### Claim 11 (depends on 10) The method according to claim 10, wherein the nasal or paranasal tissues contains a collapse in an internal nasal valve. ### Claim 12 (depends on 1) The method according to claim 1, further comprising: applying heat to the implant after implantation of the implant to alter a shape of the implant. ### Claim 13 (depends on 1) The method according to claim 1, wherein the material for the implant is a bioabsorbable polymer selected from the group consisting of Poly-L-lactic acid, Poly-d)-lactic acid, Poly-e-caprolactone, and Poly-glycolic acid. ### Claim 14 (depends on 1) The method according to claim 1, wherein the material for the implant is a metal or metal alloy selected from the group consisting of titanium-containing alloys, platinum-tungsten alloys, nickel-containing alloys, nickel-titanium alloys, nitinol, and malleable metals. ### Claim 15 (depends on 1) The method according to claim 1, wherein the material for the implant is a polymer selected from the group consisting of polystyrene, polyethylene, and polypropylene. ### Claim 16 (depends on 1) The method according to claim 1, wherein the implant is made of two or more materials. ### Claim 17 (depends on 1) The method according to claim 1, wherein the implant further includes magnetic resonance imaging visible material. ### Claim 18 (depends on 17) The method according to claim 17, wherein the magnetic resonance imaging visible material includes bands of material disposed on either end of the implant. ### Claim 19 (depends on 1) The method according to claim 1, wherein the introduction needle further includes a stop mechanism that controls movement of an advancement shaft after the introduction needle arrives at a desired location in the nasal tissue. ### Claim 20 (depends on 1) The method according to claim 1, further comprising: inserting a plurality of implants in the nasal tissue to support attachment of the lateral cartilage to the maxilla bone of the nose. ### Claim 21 A method for correcting a nasal valve collapse of a nose, the method comprising placing of an implant within a cylindrical core of an introducing needle; inserting the introducing needle into the nose; controlling movement of the implant out of the introduction needle and into nasal tissue of the nose; depositing the implant adjacent to a lateral edge of a lower lateral cartilage and a maxillary bone of the nose; and applying force to the cartilage to stent the nasal valve open, wherein the implant is made of bioabsorbable material. ### Claim 22 (depends on 21) The method according to claim 21, wherein the implant supports a lateral edge of the lower lateral cartilage to strengthen attachment of the lower lateral cartilage to the maxillary bone. ### Claim 23 (depends on 21) The method according to claim 21, wherein the implant is positioned in the nasal tissue to support a nasal airway from collapsing during inspiration. ### Claim 24 (depends on 21) The method according to claim 21, wherein the implant supports a nasal valve angle from collapsing during inspiration. ### Claim 25 (depends on 21) The method according to claim 21, further comprising: inserting a plurality of implants in the nasal tissue to support attachment of the lateral cartilage to the maxilla bone of the nose. ### Claim 26 (depends on 21) The method as claimed in claim 21, wherein the introduction needle includes a stop mechanism that controls movement of an advancement shaft after the introduction needle arrives at desired location in the nasal tissue. ### Claim 27 (depends on 26) The method as claimed in claim 26, further comprising attaching a suture extending from a trailing end of a guiding needle; attaching the suture extending from the trailing end of the guiding needle to a first end of the implant contained in the core of the introduction needle, wherein the implant further includes a suture extending from a second end of the implant, opposite the first end. ### Claim 28 (depends on 27) The method as claimed in claim 27, further comprising: guiding the implant into a desired location in the nasal tissue using at least one of the sutures extending from the first end and second end of the implant. ### Claim 29 A method for correcting a nasal valve collapse of a nose, the method comprising placing of an implant within a cylindrical core of an introducing needle; inserting the introducing needle into the nose; controlling movement of the implant out of the introduction needle and into nasal tissue of the nose; depositing the implant into the nasal tissue at the junction of an upper lateral cartilage portion and a septum cartilage portion; and applying a force on the upper lateral cartilage to support the nasal valve, wherein the deposited implant alters an internal nasal valve resulting in a change in an internal nasal valve angle, and wherein the implant is made of bioabsorbable material. ### Claim 30 (depends on 29) The method according to claim 29, wherein ejecting the implant into the nasal tissue at the junction of the upper lateral cartilage portion and the septum cartilage portion, displaces the upper lateral cartilage portion laterally away from the septal cartilage portion. ### Claim 31 (depends on 1) The method according to claim 1 further comprising placing the implant medial to lower lateral cartilage and overlying the maxillary bone. ### Claim 32 (depends on 1) The method according to claim 1 further comprising placing the implant lateral to lower lateral cartilage and lateral to the maxillary bone. ### Claim 33 (depends on 21) The method according to claim 21 wherein the depositing step comprises depositing the implant medial to the lower lateral cartilage and overlying the maxillary bone. ### Claim 34 (depends on 21) The method according to claim 21 wherein the depositing step comprises depositing the implant lateral to the lower lateral cartilage and lateral to the maxillary bone.
