fan ear plastic surgery

The ear malformation is often deformed from the upper part of the auricle to the ear (the angle of the ear is too wide, that is, the flat ear), the middle ear of the auricle is deformed (the angle between the ear and the head is too wide) and the lower ear is deformed (the earlobe Precursor. Therefore, the ear correction surgery actually includes three operations of restoring the position of the auricle, forming the ear wheel and correcting the protrusion of the earlobe. For each patient, the surgical plan should be designed according to the scope of the deformity. Treating diseases: ear disease Indication Fan wind ear plastic surgery is suitable for congenital wind ear deformity, no surgical contraindications, age 5 years old or older. It is not advisable for children to perform surgery too early, otherwise the cartilage will continue to develop in an abnormal direction. Portmann (1980) pointed out that the age of surgery is 6 to 7 years old. At this time, the auricle is only a few millimeters away from the adult's auricle, and the surgery has little effect. Contraindications Children under 1.5 years old. 2. Skin inflammation, eczema, and otitis media around the ear, suspend surgery. 3. Patients with severe cardiopulmonary disease and blood diseases. Preoperative preparation 1. Ideological preparations should explain the purpose of surgery, treatment methods, surgical procedures, effects and matters needing attention during and after surgery to the patients and their families, so that they have a correct understanding of the disease and adequate mental preparation, and actively cooperate. 2. General preparations to fully understand the medical history, check the physique, carry out the necessary tests, chest X-ray or X-ray photographs and other special examinations as needed, and should take the front, side, slope and back photos of the ear as a reference control before and after surgery. 3. Preparation of the operation area 1d before the operation, wash your hair and take a bath. Shaving the hair around the ear, the male patient should shave the beard. The female patient has a long hair braided or pulled to the opposite side. Sudden water enema before the operation of general anesthesia. A sedative was used 1 h before surgery. General anesthesia is fasted and water-free in the morning. Adult anesthesia 0.5 mg of atropine sulfate, subcutaneous injection 30 minutes before surgery, children's dosage according to doctor's advice. Surgical procedure Cartilage suture (1) Non-incision method: The contour of the ear wheel is marked with methylene blue, and the intradermal horizontal suture of the cartilage is penetrated by a nylon thread or a thread along the marking line, and the suture is taken out by the same pinhole. 1 Use the injection needle to pierce the skin from the front of the ear along the designed contour of the ear wheel, and pierce the skin from the opposite side of the ear. Then apply the methylene blue solution to the needle and withdraw the needle. Cut the skin longitudinally in the colored spots behind the ear. 2 Separate the subcutaneous, reveal the cartilage, and use a grinding bit to thin the cartilage in the stained area. 3 Then use nylon thread or silk thread to make intradermal suture through the cartilage. 4 After tightening the suture knot, a blunt round bevel that protrudes forward is formed. The incision was sutured after removing excess skin behind the ear. 2. Cartilage parallel incision (1) Pre-mark the pair of ear wheels with methylene blue, make a longitudinal incision in the skin behind the auricle, and cut the skin and subcutaneous tissue. (2) Separation under the skin, revealing the cartilage behind the auricle, making three parallel longitudinal incisions along the line of the color point and the sides, cutting the cartilage, but not cutting the front cartilage. (3) suturing the outer edge cartilage of both sides of the incision, that is, forming the bulging pair of the ear wheel and its upper leg, excising excess skin behind the ear, and suturing the incision. 10.3 3. Cuneiform cartilage strip resection (1) Fixing, puncture, and methylene blue coloring along the designed contour of the ear wheel. (2) The skin is cut longitudinally along the colored points behind the auricle, and the skin is separated subcutaneously to expose the cartilage of the ear. (3) Longitudinally remove a cartilage strip with a width of about 4 to 6 mm and perform a vertical suture in the skin through the cartilage. (4) After removing excess skin behind the ear, suture the incision. 10.4 4. Cartilage tube forming method The cartilage tube forming method is basically the same as the parallel incision method, and the illustration is slightly different. (1) Methylene blue mark. (2) Cut the cartilage behind the auricle. (3) Cartilage tube formation. (4) Excision of excessive ear cavity cartilage and skin. complication 1. Hematoma: can cause auricular cartilage necrosis, the consequences are serious. The prevention method is to stop bleeding carefully during the operation, and the surgery should be properly wrapped. If bleeding is found, hemostasis should be stopped and pressure bandaged. 2. Infection: If there is no hematoma, infection is not easy. If there is infection, it should be drained and wet coated with antibiotic gauze. 3. Pain: If the pain is severe after surgery, it indicates a hematoma or infection. The patient complained of a headache, which is usually too tight and should be re-wrapped. 4. Swelling: Mild swelling may last for several months and generally disappears naturally. 5. Skin necrosis: The blood supply of the auricle is rich, and generally no necrosis occurs. However, if the stripping surface is wide during surgery, the dressing is too tight, which may lead to skin necrosis. 6. External ear canal stenosis: When the temporomandibular joint is too high or the width of the ear is excessively changed during the operation, secondary infection may occur, and the external auditory canal stenosis may occur.
