In short. Two internal problems that need prompt assessment, how each presents, and why they are treated rather than watched after nasal surgery.

Key points

  • A collection that is drained early usually leaves the cartilage intact, and the nose keeps its support.
  • One that is left is measured in cartilage lost, and cartilage does not come back.
  • The window is short and the intervention is small, which is exactly the combination that makes waiting the wrong choice.

The findings after nasal surgery that matter most are the ones a patient cannot see. A collection of blood inside the septum and a hole in the septum both sit behind the lining of the nose, and both are found by examining the inside rather than by looking in a mirror. They are treated rather than observed, and the reason is the same in each case: the structure that supports the nose is at stake.

A collection of blood in the septum

The septum is a wall with cartilage between two layers of lining, and that cartilage takes its blood supply from the lining on both sides. Blood collecting between the layers separates the cartilage from its supply, and cartilage that loses its supply is lost. The nose then loses support, and the bridge can sink into what is called a saddle deformity. It usually presents as a nose that becomes blocked on both sides, often quickly, with pain and a feeling of pressure over the bridge.

A hole in the septum

A perforation is an opening through the septum. It can follow an untreated collection, an infection, or surgery in which the lining on both sides was damaged in the same place. It does not always cause trouble, and when it does the symptoms are crusting that will not settle, bleeding that keeps returning, a whistling sound on breathing, and sometimes a persistent feeling of blockage.

Why prompt assessment changes the outcome

A collection that is drained early usually leaves the cartilage intact, and the nose keeps its support. One that is left is measured in cartilage lost, and cartilage does not come back. The window is short and the intervention is small, which is exactly the combination that makes waiting the wrong choice.

What the examination does

The inside of the nose is examined on both sides, with a light and a speculum, and the septum is inspected along its length rather than at the front only. A collection appears as a smooth swelling of the septum that is tender and boggy rather than firm. A perforation may be visible directly, and crusting around it is often what draws attention first. Neither is diagnosed from a description over the telephone.

What happens next

A collection is drained, and the lining is kept against the cartilage while it heals. A perforation is treated according to its size and its symptoms: often with measures that keep the lining moist and free of crusting, and with surgical repair considered for larger defects or persistent symptoms. Both are then followed, because the question afterwards is whether the support of the nose has been preserved.

Seek care the same day

  • Blockage on both sides that appears suddenly or keeps worsening.
  • Pain and pressure over the bridge of the nose.
  • A crusting sore inside the nose that does not heal, or a whistling sound.

How the airway is examined on each side, and what separates swelling from structure, is described in Breathing Problems After Nose Surgery. The wider set of findings that need care is in Red Flags After Nose Surgery.

Frequently asked questions

How would I know if I had a collection in my septum?

The usual pattern is a nose that becomes blocked on both sides, often quickly, with pain over the bridge and a feeling of pressure rather than the ordinary stuffiness of early healing. Because it is inside the nose it cannot be seen in a mirror, which is why a blockage that appears suddenly or worsens is examined rather than treated with decongestants.

Does a hole in the septum always cause symptoms?

No, and small ones are sometimes found by chance much later. When it does cause symptoms they are crusting that will not settle, a whistling sound on breathing, bleeding that keeps returning, and sometimes a feeling of blockage. A hole that is producing symptoms is assessed, and one that is not may need nothing done.

Why is a collection drained rather than left to settle?

Because the cartilage that supports the nose takes its blood supply from the lining around it, and blood collecting between the two layers separates the cartilage from that supply. The cartilage can then be lost, and losing it leaves the bridge unsupported. Draining restores the contact, which is why it is done when the collection is found.

Risks & Limitations

  • A revision cannot promise a better result than the operation it is correcting. It can improve a named problem, and it can introduce a different one while doing so.
  • There is usually less cartilage available the second time, more scar tissue between the layers, and a tighter skin envelope that limits how much structure can be added before it shows.
  • A nose continues to change for roughly a year, so a result judged early is usually wrong and a revision planned early is planned from a shape that will not exist.
  • Two findings inside the nose — a collection of blood in the septum and a hole in it — can damage the support of the nose if they are not assessed promptly.

When to Seek Care

  • Breathing through the nose that keeps worsening, or a nose that is swelling fast — seek emergency care now.
  • Heavy bleeding that does not stop, or bleeding that restarts after it had settled — seek emergency care now.
  • Skin over the tip or bridge turning white, dusky, blistered or black — seek emergency care now.
  • A fever with spreading redness, heat or pus around the nose or septum — seek care the same day.
  • A hole, a whistling sound, or a crusting sore inside the nose that does not heal — seek care the same day.
