Nasal comprehensive plastic stent

Abstract

Disclosed is a nasal comprehensive plastic stent. one end of the nasal comprehensive plastic stent is connected and fixed with nasal septum cartilage (4), and the other end of the nasal comprehensiveplastic stent is connected and fixed with nose wing cartilage inner side feet (5) and a fornix (6), wherein the nasal comprehensive plastic stent is mainly used for increasing nose bridge length and nose tip height, keeping nasal columella and nostrils at stable neutral or symmetrical positions and adjusting nose tip forms and nasolabial angles. The plastic stent is characterized in that the stentis formed by oppositely sewing, cutting and modifying concave surfaces of two approximately symmetrical bent and concave ear cartilages inwards, and has a special form and a special functional partition; after relative suturing and before cutting and reshaping, the two bent ear cartilages are combined together to form a shape similar to a shell; and after being cut and modified, the stent is in arelatively straight plane and forms a definite head part (1) and tail parts (2 and 3), and the tail parts are separated like dovetail parts. The beneficial effects of the invention are as follows: 1,the defects of poor support force and stability of the ear cartilage are overcome; 2, trauma is small, and operation is safe; 3, the operation is simple and the time is saved; 4, cartilage materialsare saved, the dovetail shape can provide more stable support, and the use amount of cartilage is also saved; 5, the materials are not influenced by age and cartilage calcification; and 6, the bioniceffect is good, the ear cartilage has certain elasticity, and the nose can move.

Description

[0001] Technical field [0002] The invention relates to the technical field of plastic surgery, in particular to a bracket for comprehensive nasal plastic surgery. Background technique [0003] The comprehensive nasal plastic stent usually has a core part composed of a nasal septum extension graft and a columella support graft, and its two ends are respectively connected with the nasal septal cartilage and alar cartilage. The main function is to extend the length of the nose bridge and nose tip, keep the columella, nasal septum, and nostrils in a stable neutral or symmetrical position, and change the shape of the nose tip and nasolabial angle. Therefore, the length, height, and straightness and stability of the stent are the keys to comprehensive rhinoplasty. [0004] The comprehensive rhinoplasty bracket is usually made of 3-6 pieces of cartilage with relatively high hardness and straightness, such as costal cartilage and septal cartilage, and the combination method is 2+1,...

AI Technical Summary

Problems solved by technology

[0009] However, due to the inherent irregularity of the ear cartilage, its support stability and elongation strength are insufficient, and it is easy to deflect or retract and deform in the long term, so it is less and less recommended.

And the traditional method is to cut it into a plurality of small pieces of matrix (4 to 6 pieces) spliced ​​together, the operation is complicated and time-consuming
