Nasal necrosis

Nasal necrosis or blackening of the nose after surgery depends on the size of the necrotic tissue. Spot necrosis causes less damage, but if the amount of damaged tissue is large and the nasal skeleton is severely damaged, it affects the appearance of the nose.

Nasal necrosis

What causes necrosis of nasal tissue?

When for any reason the blood does not reach a part of the body tissue, the tissue no longer receives oxygen and is destroyed and so-called necrosis. Necrosis or death of part of the body tissue is seen in diseases such as leprosy, some autoimmune diseases, severe frostbite, trauma, accident or invasive surgery.

Nasal necrosis is a very rare problem in rhinoplasty, usually due to underlying disorders in the patient. Of course, sometimes there are drawbacks to the surgeon’s incorrect technique. When the rhinoplasty surgeon manipulates the nasal tissue too much with the wrong technique and does not show delicacy in the surgery, the blood supply to the tissue becomes disturbed and the tissue becomes black or so-called dies.

Causes of nasal necrosis:

Vascular disorders

Local infections inside the nose

Injecting and taking Accutane or Roaccutane before rhinoplasty


Improper technique of the nasal surgeon and excessive manipulation and destruction of nasal tissue by the surgeon

Rhinoplasty: It is a re-operation of the nose and because the nasal tissue has been operated and manipulated once, in early surgery for the second time, there is a possibility of damage to the nasal tissue and not reaching the blood.

Injecting non-standard gels into the nose or injecting too much gel in the wrong place on the nose.

Nasal necrosis

Does injecting fillers into the nose cause damage to the nasal tissue?

Injecting non-standard gels or injecting large amounts of gel into the inappropriate area of ​​the nose also increases the risk of necrosis. Rhinoplasty sometimes involves gel injections or manipulations to fill in the indentations or protrusions of the nose in the nasolabial fold or the crease between the lips and cheeks, which also increases the risk of necrosis.

People who have severe pain during or after the gel injection and who have changed the color of the skin of the nose in the first 24 hours to a week are more likely to have nasal necrosis. This complication with fat injection has never been reported.

Of course, any change in the color and blackness of the nasal skin does not mean necrosis. Anemia is sometimes temporary, and even with necrosis, spontaneous tissue regeneration may occur. As a result, it is necessary to wait for its range to be determined, but if it is in a place where the vessel is probably under pressure, the pressure should be removed from the vessel very quickly with reconstructive surgery.

How can nasal necrosis be prevented?

To prevent this complication after rhinoplasty, the removal of the fat layer from the patient’s skin should be done with great caution because if it is excessive, the blood supply to the nasal skin will be disrupted and the pressure caused by the splint and glue will cause necrosis of the nose and blackening of the skin. The nose will be after surgery.

How can a necrotic nose be treated?

The treatment of this complication is very complex and the patient may need several surgeries to treat it. Surgeons try to replace the necrotic area with normal body tissue, using cartilage from other parts of the body, such as the rib or ear cartilage.

But if a large part of the nose is missing, it must be replaced with a prosthesis. The condition for using a prosthesis is that the damaged tissue is completely repaired and there is no infection. Of course, an artificial ear or nose will never look like a normal ear or nose.

If the necrosis is in the middle wall of the nose, the suture and graft site will not be identified. Therefore, the type of lesion and repair will be effective as a result of the work.
