1, anesthesia and patient posture in submucosal resection of nasal septum.

2. Make an incision on the concave side of the deviated nasal septum, pull the columella to the opposite side, and cut it from top to bottom at the nasal vestibule skin of the free edge of the nasal septum cartilage, from the back of the nose to the anterior nasal spine, so that the anterior edge of the nasal septum and the anterior nasal spine are completely exposed.

3. Separate the soft tissue on the concave side of the nasal septum and the mucoperiosteum at the bottom from the incision, and fully expose the nasal septum stent on the incision side. 4. Dissociate the nasal septal cartilage from the nasal cartilage at the posterior margin of the nose, and remove a narrow strip (3 ~ 4 mm wide) at the joint between the posterior superior and posterior inferior bottom of the nasal septal cartilage and the bone, so that the whole nasal septal cartilage only adheres to the non-stripped tissue on the opposite side.

5. If the bracket of the nasal septum bone is also deviated, a nasal septum stripper can be inserted through the posterior edge of the nasal septum cartilage to separate the mucosa of the opposite nasal septum bone, and then the deviated part of the ethmoid vertical plate and the piriform bone can be taken out with nasal septum rongeur.

6. The nasal septum cartilage is bent at the most prominent part of the nasal septum cartilage depression, and several deep incisions are made on the surface of the depressed cartilage, but don't cut through the contralateral mucocartilage membrane. The length of the incision should almost reach the edge of the cartilage depression, and cartilage strips with a width of 1mm can also be removed between the incisions. After treatment, the elasticity of the nasal septum cartilage will straighten the cartilage, so just push it back to the midline.

7, check the bilateral nasal cavity, to see if there is any deviation, if there is any residual deviation, should be re-cut for processing. 8, incision suture, bilateral nasal cavity with vaseline gauze isobaric packing, 24 hours later, take out the gauze.

Preventive measures after operation:

1, the prevention focus is mainly on preventing nose trauma.

2. After orthopedic surgery, nasal discharge can be removed within 24-48 hours after surgery, and the right side can be removed the next day, and then the other side can be removed.

3. Because there is obvious mucosal reaction after intranasal surgery, coptis paste can be thinly coated in the nose after the gauze strip is removed.

4. If the incision heals well, the packing can be removed 5 days after operation.

Anyway, I found a little less cartilage in the middle of my nose after the operation. I guess it was taken away and not put back. As for the wound healing, it was still bleeding two days ago, and it was much better on the third day. Later, it was found that the doctor did not sew the wound with thread or something, but applied some ointment on cotton and cloth. When he was discharged from the hospital, he pulled out the cotton and the wound stopped bleeding.
