How to make ear cartilage?
Incision design: determine the cutting position and shape of auricle cartilage, and mark the incision line on the skin behind the auricle with an indelible marker. This line is 5 ~ 10 RAM away from the cranial ear groove and parallel to the cranial ear groove. The incision length should meet the requirements of surgical operation;
Local anesthesia: swelling anesthetic solution (0.2% lidocaine, containing 1:400000) was used. Epinephrine) is used for subcutaneous infiltration anesthesia behind ear and before ear;
Soft tissue incision and auricular cartilage exposure: cut the whole skin along the incision design line, and make blunt separation in the subcutaneous loose layer to separate the skin from the auricular cartilage and expose the auricular cartilage. The exposed area of auricle cartilage depends on the amount of cartilage obtained;
Harvesting of auricular cartilage: Use two double-tooth retractors to pull in the opposite direction, fully expose the cartilage, mark the shape of cartilage, and gently cut the whole cartilage layer with a small round blade. Enter the cartilage along the cartilage incision line with a small bending shear, separate it under the perichondrium of the preauricular, and take out the auricular cartilage piece. Using the same operation steps, you can cut multiple ear cartilage at one time;
Closure of incision: after careful hemostasis in the surgical field, the skin incision was sutured intermittently with 6-0 nylon thread and bandaged externally;
Seven characteristics of auricular cartilage rhinoplasty
1, good and stable histocompatibility:
Ear cartilage rhinoplasty has low absorption rate, can survive without blood supply, can be integrated with local tissues of the nose, is easy to fix and will not shift.
2, the operation is relatively simple:
Compared with the removal of nasal septal cartilage and costal cartilage, the operation of auricular cartilage is relatively simple and requires less surgical instruments and doctors' skills.
3, easy to carve and shape;
The usual nasal prosthesis materials are fixed in shape, so it is impossible to make a beautiful nasal tip. The use of auricular cartilage can meet the complex needs of forming alar cartilage and raising the tip of nose, and can prevent complications such as nasal deformity and perforation.
4. Touch is real:
After rhinoplasty with auricular cartilage, you don't have to worry about normal contact with your nose. Pushing the nose feels soft and realistic.
5, scar concealment:
Ear cartilage can be cut from the front or back of the auricle. Even if the cartilage is cut through the pre-auricular incision, the scar is hidden, because the incision is located at the edge of the concha cavity, and in most cases, the cartilage is cut through the post-auricular incision.
6. The cutting ability basically meets the demand;
If you want to correct the shape of the nose and the height of the bridge of the nose at the same time, it is enough to use the middle diaphragm cartilage and the single ear cartilage. General nasal tip plastic surgery, single ear cartilage can basically meet the demand, if the demand is large, you can choose binaural cartilage.
7, and the disease harm is small:
Severe pain may occur after costal cartilage resection, with occasional pneumothorax; Removal of cartilage from the nasal septum can lead to bleeding, or symptomatic perforation of the nasal septum and abnormal ventilation. And the complications of ear cartilage removal.
