Maxillary retraction correction surgery procedure

1. Incision: Make a transverse incision of the maxillary vestibular sulcus. An incision was made in the upper jaw from the 2nd molar on one side to the contralateral second molar on the contraflexion of the vestibular sulcus. Cut the mucosa and periosteum to the bone surface.

2. Exposing the maxilla: Using a periosteal stripper for subperiosteal separation on the bone surface, exposing the lateral wall of the maxilla and the root of the sacrum spine, and subdividing backwards to the jaw seam on the flap. However, do not separate too much below (toward the gums) to maintain soft tissue adhesion and ensure blood supply to the maxilla and maxillary teeth.

1. Incision: Make a transverse incision of the maxillary vestibular sulcus. An incision was made in the upper jaw from the 2nd molar on one side to the contralateral second molar on the contraflexion of the vestibular sulcus. Cut the mucosa and periosteum to the bone surface.

2. Exposing the maxilla: Using a periosteal stripper for subperiosteal separation on the bone surface, exposing the lateral wall of the maxilla and the root of the sacrum spine, and subdividing backwards to the jaw seam on the flap. However, do not separate too much below (toward the gums) to maintain soft tissue adhesion and ensure blood supply to the maxilla and maxillary teeth.

After the outer wall of the maxilla is fully peeled off, a small periosteum peeler is used to peel off the pear-shaped hole and the nasal septum, the nasal floor and the outer wall of the nose along the nasal floor.

3 Maxillary lateral and medial osteotomy: According to the marked osteotomy line, use a micro saw to cut the lateral wall of the maxillary bone. After cutting the lateral lateral wall from the anterior jaw portion outside the piriform foramen to both sides, gently cut with a bone knife. Severe medial wall of maxillary sinus. Cut the root of the nasal septum with an osteotome, and pay attention that the direction of the osteotome cannot be tilted upward when inserting it, and place the index finger on the soft palate to protect the osteotome from being cut.

4 Chiseling the posterior edge of the maxilla: Finally, at the wing maxillary seam, between the back of the maxillary tubercle and the lower end of the wing plate, cut inward with an arc-shaped sharp bone knife to separate the maxilla from the wing plate. Place the left or middle finger at the patellar mucosa near the posterior margin of the hard palate to feel the condition of osteotomy. When cutting bone, special attention should be paid: the bone knife should be placed in the lower part of the wing maxillary suture, the direction of the incision should be inward as far as possible, and the bone knife should not be cut in the upward direction to avoid damaging the wing maxillary suture. Internal blood vessels (such as the internal maxillary artery).

5. Fracture the maxilla downward: After completing the osteotomy steps, gradually apply pressure with the thumb on the anterior part of the maxilla to break the entire maxilla downward, and hold the broken maxilla to fully move it.

Move the maxilla forward so that it is suitable for the occlusal relationship of the occlusal guide to reach the expected ideal position. The dental arch splints that have been ligated in the upper and lower jaws are used for intermaxillary fixation to maintain the ideal position of the upper jaw.

1. Try to avoid getting water in the surgical department within 7 days after the operation.

2. Ensure that the surgical site is clean and prevent infection. If there is blood rash or secretions on the wound, wipe with sterile saline.

3. After the operation, the local wound can be pressure bandaged or cold-packed with ice pack, but the pressure should not be great. Once more bleeding and severe hematoma occur after the operation, you should return to the hospital in time.

4. Have a quiet and comfortable environment to rest after the operation.

5. The wound will be painful on the day of surgery, but it will gradually decrease over time. Patients should not rush to take pain tablets, because aspirin drugs will aggravate wound bleeding.

6. Avoid eating irritating foods, such as peppers.

7. Strictly follow the doctor's instructions to take medicine and return to the clinic.
