Buried Ear Surgery

Congenital auricular deformity, caused by abnormalities in the development of the first and second zygomatic arches, can be manifested as abnormalities in morphology, location, or size. Anatomy of the auricle: The auricle is a body surface organ composed of elastic cartilage as a scaffold and covered with skin, subcutaneous tissue and ligament. The auricle is symmetrical, which is equivalent to the height of the eyebrow and the nose. The horizontal axis is at an angle of 30° to the cranial side wall. It is formed by the development of the first and second arch of the embryo. It consists of yellow elastic cartilage covering the skin, and attaches to the sides of the skull by connective tissue, muscle and skin, and forms an angle of about 30° with it. The back is flat and slightly raised, and the front is uneven. The auricular cartilage consists of a single piece of yellow elastic fiber cartilage plate with a shape similar to that of the auricle. The inner part constitutes the cartilage part of the external auditory canal, and the cartilage is not formed at the bottom of the external auditory canal, forming a gap, which is called the incision between the otoscopes, and the incision is made in the ear, so that the cartilage is not damaged. Statistics have confirmed that there is no standard ear that can be used to determine whether the shape, position and proportion of the auricle are normal. Treating diseases: the auxiliary ear Indication Buried ear plastic surgery is suitable for congenital cryptic ear damage to normal appearance, and can not wear glasses. 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 preparation: Explicitly explain to the patient and family members the purpose of the operation, the treatment method, the surgical procedure, the effect and the matters that should be paid attention to during the operation, so that they have a correct understanding of the disease and fully prepared for the disease, and actively cooperate. 2. General preparation: comprehensively understand the medical history, check the physique, carry out the necessary tests, chest X-ray or X-ray photographs and other special examinations according to the needs, and should take the front, side, slope and back photos of the ear as a reference before and after the operation. . 3. Preparation of the operating area: wash your hair and bathe 1 day before surgery. 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 There are four ways to bury ear plastic surgery: Ear posterior flap (1) First draw a normal auricle outline and design a triangular flap at the back. (2) Cut the skin and under the skin. Separate and loosen the adhesion behind the auricle, and pick up the triangular flap behind the ear. (3) Pushing the formed triangular flap upwards to repair the wound in the posterior mastoid area, and the wound after the auricle is transplanted with the skin graft. 2.VY propulsion flap method (1) An isosceles triangle flap is marked with the ear of the ear. (2) Cut the skin and under the skin to loosen the adhesion of the cryptaural auricle. (3) Fold the triangular flap backwards for suture separation after subcutaneous separation. 3. Skin grafting (1) Cut the skin and subcutaneous tissue according to the lateral side of the ear canal. (2) Separation of the adhesions behind the ear, and the wounds in the posterior and mastoid areas were repaired with free skin grafts. 4. Three-leaf flap method (1) A trifoliate flap is designed along the scalp of the upper part of the ear, and its pedicle is equal to the width of the ear. (2) Incision of the skin and subcutaneous tissue, separation of the flap, and separation of the adhesion of the loose ear. (3) Folding the trifoliate flap to the posterior part of the auricle, covering the wound and suturing. (4) The free skin piece can be implanted after the wound in the flap area is reduced and sutured.
