Description

Nose column prosthesis for hump nose operation

Technical Field

The present invention relates to a nasal splint prosthesis for augmentation rhinoplasty, and more particularly, to a nasal splint prosthesis for augmentation rhinoplasty for improving the contour of the nasal splint.

Background

Generally, augmentation rhinoplasty belongs to one of the cosmetic techniques, and most of them is mainly rhinoplasty (augmentation rhinoplasty) in which the nose is elevated. Recently, in addition to the nose bridge being lifted, a nose humping operation of simultaneously lifting the nose tip has been popularized, and various different operation methods are used depending on which material is used to lift the nose tip.

Autologous cartilage (such as auricular cartilage, septal cartilage, and costal cartilage) is used in the nasal tip operation, but the number of factors for using such autologous cartilage is limited, and there is a concern that complications may occur at the site of collection. Also, artificial materials (alloplastic materials) used for the nasal tip surgery include artificial bone, PCL mesh plate (PCL mesh plate), silica gel, and the like. Various artificial materials have advantages and disadvantages, among which silica gel is the most used artificial material in augmentation rhinoplasty.

In particular, the L-shaped silicone prosthesis is widely used because it is inexpensive and has excellent tissue stability, is easily removed when performing a second operation, and can elevate the nose tip while reshaping the nose bridge. However, there are problems in that capsular contracture (capsule con traction) occurs in which the nose becomes gradually shorter after the nose augmentation operation and the skin at the tip of the nose becomes gradually thinner and more prominent, and it is necessary to develop a more suitable alternative prosthesis.

Up to now, there is an increasing need for re-operation after augmentation, which is mainly performed using the nasal septum, if it has been used, using costal cartilage or artificial bone, PCL mesh plate, etc. However, such artificial materials have many disadvantages and are difficult to be applied in a re-operation, and thus there is a high necessity for an artificial material prosthesis which is reliably applicable to a nose tip protrusion.

The background art of the present invention has been disclosed by Korean laid-open patent publication No. 2005-0084734 (published by 2005.08.29, title of the invention: nose prosthesis).

The fixing assistance portion further includes: and a third fixing hole part formed in the pillar part to have a triangular structure with the first fixing hole part and the second fixing hole part.

(Effect of the invention)

According to the nasal splint prosthesis for augmentation rhinoplasty of the present invention, the nasal bone insertion portion into which the nasal septum and the anterior nasal spinous process can be inserted is formed in the strut portion constituting the nasal splint, and the nasal tip is raised to a desired extent by the strut portion, so that the nasal splint prosthesis can be firmly and stably positioned and fixed without twisting with reference to the bone of the nose including the nasal septum and the anterior nasal spinous process.

The present invention also discloses a prosthesis that is applicable alone and that forms only a bridge, which is different from a bridge prosthesis, and can be manufactured and used separately from the bridge prosthesis. For example, the nose pillar prosthesis made of the silica gel material is used for heightening the nose pillar, the nose tip is reinforced by using autologous cartilage, and the nose bridge prosthesis made of the silica gel material or other different materials is used for heightening the nose bridge.

Therefore, the invention can reduce the capsular contracture phenomenon and the phenomenon of the shortening of the nose after operation which are caused by the use of the silica gel prosthesis with the integrated nose bridge and the nose pillar. In addition, when the autologous cartilage is insufficient or the nasal tip cannot be sufficiently raised due to the use of the costal cartilage and the nasal septum cannot be used due to the re-operation, the nose tip shaping can be easily and economically performed at a desired height using the present invention.

In addition, the nose tip is elevated by the nose tip bulge part, and the nasolabial angle is increased by the anterior eminence expansion part, so that the effect of the protruding mouth operation is presented. The Korean face skeleton has the common characteristics that the front upper jaw part is sunken and the mouth part is protruded, the front nasal spine can be expanded by the front nasal spine expanding part to present the effect like a western person, the inward contraction of the mouth can be seen from the side, and the face contour is more balanced.

Further, even if the present invention is manufactured in a standardized size and shape, the length and shape can be easily reduced or adjusted according to the needs of the patient because the silicone material is easily cut due to its characteristics. For example, depending on the degree of nose tip heightening, the tip of the nasal splint prosthesis of the present invention may be cut off and used, and when the nasolabial angle does not need to be improved, the anterior eminence enlarging portion may be further reduced and used.

Therefore, the definitions of these terms should be based on the contents throughout the specification.

Fig. 1 is an important part side view for explaining a state of use of a nasal splint prosthesis for rhinoplasty of one embodiment of the present invention.

Generally, the nasal pillar refers to the lower portion of the nasal septum 2, as viewed from the underside, like the pillar that supports the nose. The nose column prosthesis 1 for nose augmentation of the present invention is positioned at a position corresponding to the lower portion of the nasal septum 2, and has an effect of making the tip of the nose bulge and enlarging the anterior nasal eminence. The nose post prosthesis 1 for augmentation rhinoplasty of the present invention can be manufactured separately from the nose bridge prosthesis 5 for raising the nose bridge, and can be applied in combination with the nose bridge prosthesis 5 and autologous cartilage (applicable to the nose tip implant 6) of various shapes and materials.

Fig. 2 is a side view schematically showing a nose ridge prosthesis for rhinoplasty of an embodiment of the present invention, fig. 3 is a plan view schematically showing the nose ridge prosthesis for rhinoplasty of an embodiment of the present invention, fig. 4 is a sectional view taken along a-a ', B-B ', C-C ' of fig. 2, and fig. 5 is a bottom view of an important part for explaining a state of use of the nose ridge prosthesis for rhinoplasty of an embodiment of the present invention.

Referring to fig. 2, a nasal post prosthesis 1 for augmentation rhinoplasty according to an embodiment of the present invention includes a post portion 10, a nasal bone insertion portion 20, a closing portion 25, and a fixation assisting portion 30.

The pillar portion 10 has a pillar main body portion 11 constituting a nasal pillar and is made to correspond to the lower portion of the nasal septum 2. The nasal bone insertion portion 20 has a bag shape into which the nasal septum 2 and the anterior nasal spine 3 can be inserted, and is formed in an upper portion of the pillar body portion 11 so as to be open upward. The closing portion 25 is formed at a lower portion of the pillar main body portion 11, more specifically, at a lower portion of the nasal bone insertion portion 20. The closing portion 25 couples both side portions of the pillar main body portion 11 facing each other across the nasal bone insertion portion 20 to each other, and more specifically, couples a lower portion of a left side portion of the pillar main body portion 11 and a lower portion of a right side portion of the pillar main body portion 11 to each other. The fixation assisting portion 30 is a portion forming a hollow portion providing a growth of a nose living tissue to be formed on the pillar portion 10 so as to be laterally penetrated.

Referring to fig. 1 and 2, a pillar portion 10 according to an embodiment of the present invention includes a pillar main body portion 11, a nose ridge portion 12, an anterior nasal spine expanding portion 13, and an engagement stabilizing portion 16.

The support part 10 is made of a material suitable for a human body such as silicone, and has a structure in which a support main body part 11, a nose tip swelling part 12, an anterior nose spine expanding part 13, and a joint stabilizing part 16 are integrally connected. The edge and corner portions of the pillar portion 10 have a rounded shape, thereby forming a smooth contour. As described above, when the strut member 10 is made of a soft material such as silicone which can be cut or cut by a person, etc., it is first manufactured to a standard size, and then the surgeon reduces the length, adjusts the local part, or removes unnecessary parts in the operation site according to the nasal structure, the demand, etc. of the patient.

The strut body 11 is a part constituting a basic skeleton of the strut part 10, has a pillar shape extending in the front-rear direction, and is provided below the nasal septum 2. A nasal bone insertion portion 20 is formed at an upper portion of the strut body 11, and an anterior nasal spine expansion portion 13 is formed at a lower portion of the strut body 11. Referring to fig. 1 and 5, the left and right side portions of the strut body 11 are in contact with the lower alar cartilage 4.

The nose tip rising portion 12 is formed to extend from the front end portion of the strut body 11, more specifically, to the front of the nasal septum 2, in order to rise the nose tip. The nose tip rising degree can be adjusted according to the extended length of the nose tip rising portion 12. After adjusting the nose tip raised part 12 in accordance with the length to be raised, the surgeon fixes a nose tip implant 6 (see fig. 5) such as auricular cartilage to the nose tip raised part 12 using a thread T, and finally determines the height of the nose tip raised part. After the nose tip is heightened through such a process, as shown in fig. 1, a nose bridge prosthesis 5 of various materials and shapes can be additionally used.

Fig. 6 is a side view schematically showing a significant part of the nose shape before the nasal prong prosthesis for rhinoplasty of one embodiment of the present invention is used, and fig. 7 is a side view schematically showing a significant part of the nose shape of the nasal prong prosthesis for rhinoplasty of one embodiment of the present invention is used.

Referring to fig. 6, nasolabial angle (N1) is an angle formed by the nasal pillar and the human body when looking sideways. Even if the length of the nose column is the same, the shorter the nose appears the more upward the tip of the nose, and the longer the nose appears the more downward the tip of the nose. The more the male hormone is secreted, the more the nose tip is downward, the average nasolabial angle of male people is 90-95 degrees, and the average nasolabial angle of female people is 105-115 degrees. Meanwhile, the tip of the nose can droop with aging, the tip of the nose can become mature when facing downwards, and the tip of the nose can become young when facing upwards.

The impression is determined by the nasolabial angle N1, the smaller the nasolabial angle N1, the more cluttered the side view, and the more the tip of the nose droops. The anterior nasal eminence enlargement portion 13 is a portion for improving the nasolabial angle N1, more specifically, a portion for further expanding the nasolabial angle N1, is formed to protrude downward at the lower portion of the pillar portion 10, and extends toward the lower portion of the anterior nasal eminence 3.

Referring to fig. 1 and 2, the anterior eminence enlargement portion 13 according to an embodiment of the present invention includes an expansion protrusion 14 and a nasolabial angle forming portion 15.

The expanding protrusion 14 is formed integrally with the pillar body 11 at the lower part of the pillar body 11, and extends from the front part of the anterior nasal spine 3 to the lower part of the anterior nasal spine 3. The expansion projection 14 has an effect of expanding the size of the anterior nasal spine 3 in the anteroposterior direction and the vertical direction. Referring to fig. 1 and 2, the expansion protrusion 14 according to an embodiment of the present invention includes a front expansion portion 141 and a lower expansion portion 142.

The front expansion portion 141 is connected to the lower portion of the pillar body 11 and is positioned in front of the front nasal spine 3 to provide an aesthetic effect of expanding the front nasal spine 3 forward. The lower expanded portion 142 is for exhibiting an aesthetic effect of expanding the anterior nasal spine 3 to the lower side, and is formed successively at the lower portion of the anterior expanded portion 141, at the lower side of the anterior nasal spine 3.

The nasolabial angle forming portion 15 is a portion that forms the improved posterior nasolabial angle N2 together with the pillar main body portion 11 and the human body, and is formed at a front portion of the expansion protrusion 14, more specifically, continuously and obliquely from a lower portion of the pillar main body portion 11 across the front expansion portion 141 and the lower expansion portion 142. The nasolabial angle-forming portion 15 is formed to be inclined rearward as it approaches the lower portion.

The front nasal spine expanding portion 13 configured as described above can provide an aesthetic effect of expanding the size of the front nasal spine 3. More specifically, the nasolabial angle N1 at the angle shown in fig. 6 is increased and enlarged to the angle of the improved posterior nasolabial angle N2 as shown in fig. 7, thereby forming a facial contour giving a soft impression.

In addition, compared with the western people, the oriental people have the advantages that the front upper jaw part is sunken backwards, the front nasal spine 3 is smaller, the mouth appears to be protruded, the effect similar to the mouth correction can be achieved by enlarging the size of the front nasal spine 3, and therefore the dental correction operation with complicated process is not needed.

The junction stabilizer 16 is a portion for fixing the nasal splint prosthesis 1 for rhinoplasty of the present invention to the autogenous bone of the nose, more specifically, a portion for more stably fixing to the nasal septum 2 or the like, and is formed to extend upward at the left and right side portions of the strut part 10 via the nasal bone insertion portion 20. Referring to fig. 3 and 4, the engagement stabilizer 16 of one embodiment of the present invention includes expansion wings 161 and expansion contact portions 162.

The expansion wing 161 is formed to extend upward from the upper portion of the pillar main body 11. A pair of expanding wing portions 161 are formed at the left and right sides to be respectively connected to the left and right sides of the nasal septum 2. The dilating wing 161 has a size and an area that can be fixed to the nasal septum 2 by being engaged with the surgical thread T.

The expansion contact part 162 is a part that is connected to the side of the nasal septum 2 and is formed continuously with the inner face of the nasal bone insertion part 20. Accordingly, the depth and size of the nasal bone insertion portion 20 can be increased to the extent corresponding to the width and area of the expansion wing portion 161.

With the pair of the expansion wing portions 161 and the expansion contact portion 162 on the left and right sides, not only the contact area with the nasal septum 2 can be ensured more clearly, but also the surgical thread T can be fixed to the nasal septum 2 more firmly and stably. Accordingly, the application of the present invention is more reliably achieved without distortion with reference to the nasal septum 2.

Referring to fig. 2 to 4, a nasal bone insertion portion 20 according to an embodiment of the present invention includes an insertion groove portion 21, a nasal septum insertion portion 22, an anterior nasal spine insertion portion 23, and a groove adjustment portion 24.

The insertion groove portion 21 is a portion for inserting the lower portion of the nasal septum 2 and the anterior nasal spine 3, and is formed to extend in the front-rear direction at the upper portion of the pillar portion 10. The insertion groove portion 21 has a shape corresponding to a nasal bone connected from the nasal septum 2 to the anterior nasal spine 3. More specifically, the upper portion has a width that is wider than the lower portion, while the rear portion has a width that is wider than the front portion.

Accordingly, the nasal splint prosthesis for rhinoplasty 1 of the present invention can be engaged with the nasal bone connected from the nasal septum 2 to the anterior nasal spine 3 from a plurality of directions and to a uniform degree (pressure, etc.) to form a natural contour together with the nasal septum 2 and the anterior nasal spine 3. Also, by the action of moving the nasal prong prosthesis for rhinoplasty 1 of the present invention from the front to the lower side to the rear to the upper side of the nasal septum 2 and the anterior nasal spine 3, the nasal septum 2 and the anterior nasal spine 3 are inserted into the insertion groove portion 21 without interfering with other portions.

The septum insertion portion 22 is an open portion that forms a main insertion path of the septum 2 inside the insertion groove portion 21, and is formed to be open at an upper portion of the insertion groove portion 21. The anterior nasal spine insertion portion 23 is an open portion that forms a main insertion passage of the anterior nasal spine 3 inside the insertion groove portion 21, and is openly formed at a rear portion of the insertion groove portion 21.

The nasal septum insertion portion 22 and the anterior nasal spine insertion portion 23 have a shape continuous and connected to each other. Accordingly, the nasal septum 2 and the anterior nasal spine 3 are inserted into the insertion groove portion 21 through the nasal septum insertion portion 22 and the anterior nasal spine insertion portion 23, respectively, but may be inserted into the insertion groove portion 21 through any one of the nasal septum insertion portion 22 and the anterior nasal spine insertion portion 23, as needed and convenient.

The groove adjusting portion 24 is a portion constituting the inner end portion of the insertion groove portion 21, and has a continuous linear form. If the nasal splint prosthesis 1 for rhinoplasty of the present invention is made of a soft material such as silicone that can be cut with a tool or by human power, the surgeon can cut the groove adjustment portion 24 at the operation site. The size of the insertion groove 21 can be adjusted by expanding it in various ways according to the patient's nose configuration, requirements, etc., according to the cutting depth of the cutting groove adjuster 24.

Referring to fig. 2, the fixing assistance part 30 according to an embodiment of the present invention includes a first fixing hole part 31, a second fixing hole part 32, and a third fixing hole part 33.

The first fixing hole 31 is formed to penetrate in the lateral direction at a position corresponding to the pillar main body 11 of the pillar portion 10. The second fixing hole portion 32 is formed on the pillar portion 10 to penetrate in the lateral direction and communicates with the nasal bone insertion portion 20. One side of the second fixing hole portion 32 is located at the nasal bone insertion portion 20, and the other side of the second fixing hole portion 32 is located at the engagement stabilizing portion 16. A second fixing hole 32 is provided at a position spaced from the rear of the first fixing hole 31.

The third fixing hole 33 is formed to penetrate the pillar portion 10 in the lateral direction, has a triangular structure together with the first fixing hole 31 and the second fixing hole 32, and is provided at a distance in the front-rear direction and the up-down direction. More specifically, the third fixing hole portion 33 is provided below the first fixing hole portion 31 and the second fixing hole portion 32, and at least a part thereof is located at the expanded projection portion 14. The diameters of the first fixing hole portion 31, the second fixing hole portion 32, and the third fixing hole portion 33 are 1 mm.

After the nasal operation using the nasal splint prosthesis 1 for rhinoplasty of the present invention is completed, the living tissue of the nose grows from the open both ends of the first fixing hole portion 31, the second fixing hole portion 32, and the third fixing hole portion 33 and enters the inside of the first fixing hole portion 31, the second fixing hole portion 32, and the third fixing hole portion 33, whereby the nasal splint prosthesis 1 for rhinoplasty of the present invention can be more stably fixed to the original nasal bone of the patient.

The first fixing hole 31, the second fixing hole 32, and the third fixing hole 33 naturally and firmly bond the strut body 11 and the living tissue of the patient at three places spaced apart from each other in a triangular structure without adding any additional member. In particular, when the nasal prong prosthesis 1 for augmentation rhinoplasty of the present invention is fixed to the nasal septum 2, in addition to fixing the engagement stabilizing portions 16 to the nasal septum by the surgical thread T, it is possible to additionally achieve the combination of the nasal septum 2 inserted into the insertion groove portion 21 and the living tissue inserted into the second fixing hole portion 32.

According to the nasal splint prosthesis 1 for augmentation rhinoplasty of the present invention configured as described above, the nasal bone insertion portion 20 into which the nasal septum 2 and the anterior nasal spine 3 can be inserted is formed in the strut portion 10 constituting the nasal splint, and the tip of the nose is raised to a desired extent by the strut portion 10, so that the positioning and fixation can be performed firmly and stably without twisting based on the bone of the nose including the nasal septum 2 and the anterior nasal spine 3.

Also, the present invention discloses a prosthesis which is different from a prosthesis constituting a bridge of the nose, can be applied alone, and is constituted only by a bridge of the nose, and can be manufactured and applied separately from the bridge of the nose prosthesis. For example, the nose pillar prosthesis 1 made of silicone material of the present invention is used to elevate the nose pillar, the nose tip is reinforced by autologous cartilage (equivalent to the nose tip implant 6), and the nose bridge prosthesis 5 made of silicone material or other different material is used to elevate the nose bridge.

Therefore, the invention can reduce the capsular contracture phenomenon and the phenomenon of the shortening of the nose after operation caused by the application of the silica gel prosthesis with integrated nose bridge and nose pillar. In addition, when autologous cartilage is insufficient or when the nasal tip cannot be sufficiently raised due to the use of costal cartilage and the nasal septum cannot be used due to the re-operation, the present invention can be used to easily and economically perform the nasal tip reshaping at a desired height.

In addition, the nose tip is raised by the nose tip bulge part 12, and the nose lip angle N1 is increased by the anterior nasal spine expansion part 13, so that the operation effect of the protruding mouth is presented. The Korean face skeleton has the common characteristics that the front upper jaw part is sunken and the mouth part is protruded, the front nose spine 3 can be expanded by the front nose spine expansion part 13 to present the effect like a western person, the mouth is seen to be contracted inwards from the side, and the face outline is more balanced.

Further, even if the present invention is manufactured in a standardized size and shape, the length and shape can be easily reduced or adjusted according to the needs of the patient because the silicone material is easily cut due to its characteristics. For example, depending on the degree of nose tip heightening, the tip of the columella prosthesis 1 of the present invention (corresponding to the nose tip bulge 12) may be cut off and used, and when the nasolabial angle N1 does not need to be improved, the anterior eminence enlargement part 13 may be further reduced and used.

While the invention has been described with reference to the embodiments shown in the drawings, which are intended to be illustrative only, various modifications and other equivalent embodiments will be apparent to those skilled in the art. Therefore, the true technical scope of the present invention should be determined by the appended claims.
