Symptoms of Septal Perforation
Septal perforation symptoms vary considerably. Some people notice very little, while others experience crusting, dryness, nosebleeds, whistling, discomfort or a persistent sensation of nasal blockage.
Symptoms depend on more than the size of the opening. Its position, surrounding tissue, airflow and other nasal conditions can all influence what a patient experiences.
Air crossing the opening can create turbulence around the edge of the perforation.
Not Every Septal Perforation Feels the Same
A perforation can be present without causing severe symptoms, while another person may find a relatively similar defect very troublesome.
The way air moves through the nose, the condition of the mucosal lining, crusting, inflammation and other nasal problems can all affect the symptoms a patient notices.
For that reason, symptom severity cannot be predicted simply by looking at a measurement of the opening.
Symptoms Associated With Septal Perforation
A person may experience one symptom, several symptoms or almost none. The pattern varies between patients.
Nasal Crusting
Turbulent airflow and drying around the edge of the perforation can contribute to the formation of crusts.
Crusting may itself cause irritation, discomfort and bleeding when disturbed.
Dryness
Altered airflow can increase drying of the mucosal lining around the perforation.
Patients may describe the nose as dry, raw, irritated or uncomfortable.
Nosebleeds
Dry or crusted tissue around the perforation may become irritated and bleed.
Bleeding can range from occasional spotting to more troublesome recurrent nosebleeds.
Whistling During Breathing
Air moving through the septal opening can sometimes create an audible whistle.
The sound may be more noticeable during quiet breathing, sleep or exercise.
Nasal Obstruction
A septal perforation can paradoxically make the nose feel blocked even though there is an opening in the septum.
Turbulent airflow, crusting and other nasal conditions can all contribute to this sensation.
Pain or Irritation
Some patients experience soreness, tenderness, burning or discomfort inside the nose.
Pain is not present in every case and should be considered alongside other nasal findings.
Nasal Discharge
Rhinorrhoea or nasal discharge can occur in association with a perforation.
Persistent coloured discharge should not automatically be attributed to the perforation because other nasal or sinus conditions may be present.
Unpleasant Smell
Heavy crusting or retained secretions can sometimes be associated with an unpleasant smell.
Persistent foul smell deserves assessment, particularly if there is discharge, pain or significant inflammation.
A Septal Perforation Changes the Way Air Moves Through the Nose
In the normal nose, inspired air travels through the left and right nasal passages.
A perforation introduces another pathway. Air can cross through the septum, disturbing the normal flow pattern.
The resulting turbulence is particularly important around the margins of the opening, where it can contribute to mucosal drying and irritation.
Inspired air approaches the opening in the nasal septum.
Some airflow passes through the perforation rather than remaining within one nasal passage.
Flow around the edge of the perforation becomes disturbed.
Dryness may contribute to crusting, irritation and bleeding.
Why Does My Nose Feel Blocked if There Is a Hole in the Septum?
Nasal breathing is not simply determined by how large the physical airway looks.
The sensation of breathing depends partly on how air travels through the nose and interacts with the nasal lining.
A perforation can disturb this pattern. Crusting, inflammation, a deviated septum, enlarged turbinates, allergy or sinus disease may also contribute.
Why Can Septal Perforation Cause Nosebleeds?
The front part of the nasal septum has a rich blood supply. When the lining around a perforation becomes dry, irritated or crusted, bleeding can occur more readily.
Recurrent nosebleeds can have other causes too. Persistent bleeding therefore deserves appropriate assessment rather than being assumed to arise from the perforation alone.
The nasal septum contains a rich vascular network. What Determines How Symptomatic a Perforation Is?
Size matters, but it is only one part of the clinical picture.
Position
More anterior perforations are often more likely to produce airflow-related symptoms such as dryness, crusting and whistling.
Size
Dimensions influence airflow and treatment planning, but larger does not automatically mean proportionally worse symptoms.
Tissue Health
Healthy, moist surrounding mucosa behaves differently from tissue affected by inflammation, scarring or heavy crusting.
Airflow
The pattern of turbulence through and around the defect can influence symptoms significantly.
Other Nasal Conditions
Allergy, turbinate enlargement, sinus disease or septal deviation may contribute to symptoms at the same time.
Previous Surgery
Previous operations may alter anatomy, scarring and tissue quality, affecting both symptoms and treatment options.
Not Every Nasal Symptom Is Caused by the Perforation
A person with a septal perforation can also have allergic rhinitis, sinus disease, enlarged turbinates, septal deviation or other nasal conditions.
Symptoms such as facial pressure, persistent coloured discharge, reduced smell or congestion therefore need to be considered in the context of the whole nose rather than automatically blamed on the perforation.
This is one reason clinical examination is useful: treatment should target the actual contributors to the patient’s symptoms.
Can Septal Perforation Affect Smell?
Some patients report changes in smell, particularly where crusting, discharge, inflammation or other nasal disease is present.
Loss or reduction of smell has many possible causes, so it should not automatically be attributed to the septal opening itself.
Other Factors May Include
- Chronic rhinitis
- Nasal polyps
- Chronic rhinosinusitis
- Infection or inflammation
- Previous nasal surgery
- Other neurological or post-viral causes
Can Someone Have a Septal Perforation Without Knowing?
Yes. Some septal perforations cause relatively few symptoms and may be identified during a nasal examination performed for another reason.
The presence of a perforation therefore does not automatically mean a person needs surgery.
The clinical approach considers the patient’s symptoms, cause, perforation characteristics and surrounding tissue rather than treating the presence of an opening alone.
Explore treatment options →Consider ENT Assessment if Symptoms Are Persistent or Changing
Assessment can confirm whether a perforation is present, determine its characteristics and consider whether another nasal condition is contributing.
Recurrent Nosebleeds
Particularly where bleeding is becoming more frequent or difficult to control.
Persistent Heavy Crusting
Especially where crusting causes bleeding, discomfort or unpleasant smell.
Ongoing Nasal Obstruction
Assessment can identify whether additional nasal factors are contributing.
Symptoms After Previous Surgery
New symptoms following septoplasty or other nasal surgery deserve appropriate review.
Apparent Change in the Perforation
Increasing symptoms or suspected enlargement should be clinically assessed.
Change in Nasal Shape
Visible structural change warrants specialist examination.
Seek Urgent Medical Assistance When Appropriate
Severe or uncontrolled nasal bleeding, significant breathing difficulty or another acute medical problem should not wait for a website enquiry or routine appointment response.

Understanding Which Symptoms Come From the Perforation
Mr Hassan Elhassan — Consultant ENT Surgeon
Symptoms such as obstruction, crusting or bleeding can have more than one contributing factor. Clinical assessment helps distinguish the effects of the perforation from other nasal conditions and supports individual treatment planning.
The symptoms described on this page can occur with septal perforation but are not specific to it. Similar symptoms may occur with other nasal conditions. Individual diagnosis requires appropriate clinical assessment.
