Definitions

• the present invention relates to a nasal implant. More particularly, the present invention relates to a nasal implant, in which a front end portion of the nasal implant reaches the glabella when the nasal implant is inserted into the nose so that a smooth curved line is formed at a region where the forehead meets the nose and the overall length of the nose can be enlarged, and in which dual hardness is imparted to a nasal ridge part of the nasal implant by means of a high-hardness portion located at a nasal bone region and a low-hardness portion surrounding the high-hardness portion so that a patient may feel as if the patient touches a hard bone, due to the high-hardness portion, when the patient touches the nasal bone region and the skin irritation is minimized due to the low-hardness portion, thereby improving satisfaction of the patient.
• Background Art
• Rhinoplasty is the most representative facial cosmetic operation. Such rhinoplasty is classified into aesthetic rhinoplasty and functional rhinoplasty.
• the aesthetic rhinoplasty is performed in order to lift the flat nose or to correct the deviated nose.
• the functional rhinoplasty is performed so as to correct harelip nose deformity or to reconstruct the nose deformed due to malignant tumoral diseases.
• the nose of the human body consists of a pair of nasal bones occupying the upper third (1/3) of the nose and two pairs of cartilages occupying lower two-thirds (2/3) of the nose.
• the nasal bone and the cartilage have cross-sections of round shapes.
• an inner surface of the nasal implant which closely adheres to the nasal bone, has a flat structure, so that the inner surface may not precisely adhere to an outer surface of the nasal bone when the nasal implant has been inserted into the nose.
• the nasal implant may seriously irritate the skin.
• a nasal tip part of the nasal implant is exposed to the exterior by penetrating the skin.
• the nasal tip part may prominently protrude from the nose so that a person who has undergone rhinoplasty may feel shame and dissatisfaction.
• the conventional nasal implant is made from soft silicon, there is a difficulty in carving work, which is performed in order to carve the nasal implant corresponding to the shape of the nasal bone during the cosmetic operation.
• the nasal implant may be bent while it is being inserted into the periosteum.
• there is a great difference of hardness between the nasal implant and the nasal bone if the nasal implant is made from silicon having lower hardness, so the person may feel strange after rhinoplasty.
• the conventional nasal implant extends from a nasal ridge forming a nasal bridge of the nose and is bent at a substantially right angle in the vicinity of the nasal tip, so that the conventional nasal implant has a substantially L-shaped structure.
• the conventional nasal implant may touch the nasal tip when the person takes deep breath, sings a song or makes a wry face, so that the person may feel pain.
• a rounded part of the conventional nasal implant that is, a vertex part of the conventional nasal implant may be exposed to the exterior by penetrating the skin.
• an object of the present invention is to provide a nasal implant, in which a front end portion of the nasal implant extends to the glabella while passing through the nasion when the nasal implant is inserted into the nose and the extension part of the front end portion of the nasal implant is smoothly curved so that a smooth curved line is formed at a region where the forehead meets the nose and the overall length of the nose can be enlarged.
