2. Technical principle

Camel hump rhinoplasty is a kind of plastic surgery mainly aimed at prominent nasal peaks, with or without long, drooping or curved nasal tips. During the operation, it is necessary to intercept the prominent bone tissue, narrow the back of the nose and trim the lower part of the nose, so the anatomy is deep and the trauma is relatively large, which belongs to the second-level project stipulated by the Ministry of Health. When choosing the operation method, it is recommended to go to a regular medical institution for treatment.

3. Adapt to the crowd and taboo crowd

1) adapt to the crowd

(1) Simple nose protrusion.

② Patients with long nasal tip or curved nasal tip.

(3) affect the smooth breathing.

People who are eager for beauty.

2) Taboo crowd

① Cardiovascular and cerebrovascular diseases, liver diseases, diabetes, abnormal coagulation function and impaired function.

② Long-term use of anticoagulants, vasodilators and corticosteroids.

③ The focus of infected patients is in the nose and its surrounding skin.

(4) People who have psychological barriers, high expectations and are too strict with the contour of the nose.

⑤ Menstrual and lactating women.

4. Preoperative design: design a line from the root of the patient's nose to the tip of the nose and mark it to show the pre-cut part.

5. Technical methods

(1) The patient lies flat, and the operating area and surrounding tissues are disinfected.

② Anesthesia: Generally, local anesthesia is used.

③ Incision: bilateral intranasal incision was made between alar cartilage and nasal cartilage. For those with high protrusion, generally choose under the columella 1/3, bilateral nasal vestibule incision, fully expose the operating area.

④ Stripping: In clinic, circular blunt bending scissors are often used for extensive subcutaneous stripping of the whole nose bridge on the surface of alar cartilage and subperiosteal stripping at the pre-cut bone peak.

⑤ Cutting off the bone peak: Generally, the bone peak is smoothed by a nose saw or chisel.

⑥ Narrowing of nasal dorsum: The frontal process of the maxilla on both sides is chiseled through the nasal or extranostril approach, resulting in fracture, and then the nasal bones and lateral nasal cartilage on both sides are re-closed with appropriate force to make them in the correct position.

⑦ Tip trimming: If the tip of nose is long, generally pull the lower end of nasal cartilage out of the incision and cut it off properly; For patients with drooping nasal tip, the anterior end of nasal septum cartilage was removed at the medial foot of alar cartilage, and then the alar cartilage and nasal septum cartilage were sutured and fixed to raise the nasal tip. For those with wide alar, the upper edge of alar cartilage is generally pulled out from the incision, and a part of its upper edge and lateral side is taken out appropriately.

⑧ Suture the wound edge, press and fix it, bandage it, and finally fill the nasal cavity with iodoform gauze.

6. Risks and complications

① Hematoma: When handling the frontal process of maxilla during operation, it is easy to produce hematoma around the nose, and occasionally it is found in the inner canthus. It is often caused by insufficient external pressure or injury to the dorsal nasal artery or medial canthus artery during osteotomy. Small hematoma can be absorbed naturally, and larger hematoma can be treated by internal medicine.

② Bleeding: postoperative bleeding is mostly caused by rough operation during operation or disorder of coagulation mechanism of patients.

③ Infection: Incomplete disinfection before or during operation may lead to postoperative wound infection.

④ Secondary deformity: due to excessive resection of nasal bone and cartilage during operation; When reducing the nasal dorsum, the lateral osteotomy position is too high.

⑤ Inadequate correction: Inadequate removal of osteochondrosis is the main reason, and reoperation can be performed after 3 months if necessary.

⑥ The effect is not ideal: improper selection of new posture or unstable fixation during operation may correct the bad appearance after operation.

7. Recovery time

About 7 days after operation, nasal packing gauze can be taken out and stitches can be removed. After 2 weeks, the external nose fixation can be removed, and the external nose collision should be avoided in the next few months. The time of full recovery varies with individual constitution.

8. Take notes

1)

① The humpback correction technique is difficult, and it is necessary to find a regular hospital or institution for treatment.

② Before operation, make sure that you are healthy, and there is no infectious disease or other body inflammation.

③ Don't make up before the operation.

Smokers need to quit smoking one week in advance.

2) Matters needing attention after operation

① Don't eat irritating food after operation.

(2) follow the doctor's advice.
