Complications of Septal Perforation
Many septal perforations remain stable and do not develop major structural problems. In some patients, however, persistent crusting, tissue injury, enlargement or loss of septal support can become clinically important.
The likelihood of complications depends on the cause, size and position of the perforation, surrounding tissue health, previous surgery and whether an ongoing damaging process is present.
Assessment considers the opening itself, surrounding mucosa and the remaining structural support of the nose.
Symptoms Are Not the Same as Complications
Crusting, whistling, dryness and nosebleeds are recognised symptoms of septal perforation. They do not automatically mean that the nose is structurally deteriorating.
A complication refers more to a problem that develops as the condition progresses or as surrounding tissue becomes affected.
Structural complications are particularly relevant in selected larger, complex or actively progressive perforations, but they should not be presented as an inevitable consequence for every patient.
What a Patient May Experience
What Can Become Clinically Important
What Can Happen in Selected Patients?
These problems are possible rather than inevitable. Individual risk varies according to the perforation and its underlying cause.
Persistent Crusting & Tissue Irritation
Altered airflow can continue to dry the margins of the perforation. Repeated crusting can irritate the lining and make the nose uncomfortable.
Persistent manipulation of crusts may further traumatise already vulnerable tissue.
Recurrent or Increasing Nosebleeds
Dry, inflamed or repeatedly traumatised mucosa around the perforation may bleed more readily.
Persistent or worsening bleeding should be assessed rather than simply assumed to be an unavoidable part of the condition.
Enlargement of the Perforation
Some perforations may become larger over time, particularly where there is persistent tissue injury, heavy crusting, manipulation or an ongoing underlying cause.
Enlargement is not inevitable and many perforations remain stable.
Loss of Septal Structural Support
The nasal septum contributes to the internal support of the nose.
Larger or strategically located defects can, in selected cases, threaten the remaining supporting framework.
Saddle-Nose Deformity
Significant loss of dorsal septal support can allow the bridge of the nose to become depressed, producing what is known as a saddle-nose deformity.
This is a structural complication associated with selected larger or destructive defects, not every septal perforation.
More Complex Nasal Airway Problems
Structural changes, scar tissue, previous surgery and other nasal conditions may contribute to breathing difficulty alongside the perforation.
The source of obstruction should therefore be assessed rather than attributed automatically to the opening itself.
Why Might a Perforation Become Larger?
Enlargement can occur when tissue around the margins continues to be damaged or fails to remain healthy.
The risk depends on the individual clinical situation and does not mean that every perforation will progressively expand.
Continued exposure, inflammation or local trauma can affect the perforation margin.
Persistent drying can contribute to repeated irritation of the lining.
Picking or forcibly removing crusts can further injure vulnerable tissue.
Where the cause remains active, treating the underlying process may be important.
The septum contributes to the central support system of the nose as well as separating the two nasal passages.
How Can a Perforation Affect the Shape of the Nose?
Structural problems become relevant when enough supporting septal cartilage is lost or weakened.
The nasal septum forms part of the support for the bridge and middle portion of the nose. A small stable perforation does not necessarily compromise that support.
Larger defects, perforations extending towards important supporting areas, previous surgery or destructive disease can make structural integrity more important to assess.
What Does “Saddle Nose” Mean?
The term describes loss of normal dorsal support causing a depression in the bridge of the nose.
Septal Support Is Reduced
Loss or weakening of structural septal cartilage can reduce support within the middle of the nose.
The Nasal Bridge Can Depress
In more advanced structural compromise, the bridge may lose some of its normal height.
Breathing May Also Be Affected
Structural changes can alter the nasal airway as well as external appearance.
Reconstruction May Be More Complex
When perforation and structural deformity coexist, treatment planning may need to address both.
Does Every Septal Perforation Get Worse?
No. Progression is not inevitable.
Some perforations can remain stable for many years, particularly when the underlying cause has stopped and the nasal lining is kept healthy.
Conservative management may therefore be entirely appropriate for some patients, particularly when symptoms are limited and there is no concerning progression.
Appropriate humidification and nasal care can reduce dryness and crusting.
Minimising manipulation helps protect vulnerable mucosal margins.
An active underlying process should be managed where identified.
Significant changes can be reassessed rather than assumed to be harmless.
Sometimes the Bigger Risk Is What Caused the Perforation
Septal perforation can result from surgery, trauma, intranasal exposure, inflammatory disease, infection and other less common conditions.
Where the cause is uncertain or where the clinical picture suggests an ongoing systemic process, further investigation may be more important than simply treating the hole.

Failure to recognise an active inflammatory, infectious or neoplastic process can delay appropriate treatment.
Equally, the presence of a perforation does not mean that a patient automatically has one of these conditions.
A Septal Perforation Does Not Automatically Mean…
The Hole Will Continue Growing
Enlargement can occur, but many perforations remain stable.
Your Nose Will Collapse
Major structural complications are associated with selected large or destructive defects, not every perforation.
You Need Surgery
Management depends on symptoms, tissue health, cause and individual clinical findings.
Every Nasal Symptom Comes From the Perforation
Allergy, turbinate enlargement, sinus disease, septal deviation and previous surgery may also contribute.
Changes That Deserve ENT Assessment
New or worsening symptoms do not necessarily mean a serious complication, but they may justify reassessment.
Increasing Crusting
Particularly if it becomes difficult to manage or repeatedly causes bleeding.
More Frequent Nosebleeds
Persistent or progressively troublesome bleeding warrants review.
Suspected Enlargement
A change in symptoms or previous measurements may justify reassessment of the perforation.
Increasing Nasal Obstruction
Other structural or inflammatory causes may also need evaluation.
Change in Nasal Shape
A new depression, twisting or visible structural change should be assessed.
Persistent Pain or Discharge
These symptoms may have several causes and should not simply be attributed to the perforation.
Do Not Use a Routine Website Enquiry for an Emergency
Severe or uncontrolled bleeding, significant breathing difficulty, rapidly increasing swelling or another acute medical problem should receive appropriate urgent medical assessment.

Assessing the Perforation and the Remaining Nasal Support
Mr Hassan Elhassan — Consultant ENT Surgeon
A septal perforation assessment considers the opening itself, surrounding mucosa, previous surgery, symptoms, likely cause and whether the structural framework of the nose remains adequately supported.
This page describes possible complications in general terms. The presence of a septal perforation does not mean that these problems will develop. Individual risk and treatment recommendations require appropriate clinical assessment.
