Functional nose surgery treats, in a single operation, the structural problems that make breathing through the nose difficult: a deviated septum, enlarged turbinates, nasal valve collapse and deformities of the nasal framework. The goal is to open the airway; the outer appearance is preserved or, if wanted, improved at the same time.
This page explains the scope of functional nose surgery, which problems it aims to solve, how the operation proceeds and what recovery involves.
What is functional nose surgery?
Nasal obstruction often has more than one cause. A deviated septum is common, but enlarged turbinates and nasal valve narrowing frequently accompany it. An operation that corrects only the septum may not relieve obstruction sufficiently if valve collapse is present.
Functional nose surgery evaluates all of these structures together. The AAO-HNS clinical consensus statement on nasal valve compromise stresses that the diagnosis should rest on examination findings and that treatment should be directed at the site of narrowing.
| Structure | Problem | Surgical approach |
|---|---|---|
| Septum | Deviation, spur | Septoplasty |
| Inferior turbinates | Enlargement (hypertrophy) | Turbinate reduction (radiofrequency, partial resection) |
| Internal nasal valve | Narrow angle, collapse | Spreader grafts or flaps |
| External nasal valve | Side-wall collapse | Alar batten grafts |
| Nasal framework | Crooked nose, collapsed bridge | Osteotomies, dorsal grafts |
Who is a candidate?
Functional nose surgery is considered in patients with nasal obstruction that has a structural cause on examination and has not responded adequately to medical treatment.
- Persistent or one-sided nasal obstruction
- Collapse of the nasal side wall on breathing in
- Habitual mouth breathing, night-time congestion
- Symptoms that persist despite sprays and medication
- A crooked nose together with breathing difficulty
- Obstruction that began after a previous nasal operation
In mucosal causes such as allergic rhinitis, medical treatment is optimised first; surgery is planned for structural problems.
How is the operation performed?
Functional nose surgery is performed under general anaesthesia and takes 1.5–3 hours, depending on how many structures are addressed. Internal corrections can be done through incisions inside the nose; valve grafts or framework correction may call for the open approach.
- Septum: deviated cartilage and bone are straightened; harvested cartilage can serve as graft material.
- Turbinates: enlarged inferior turbinates are reduced with radiofrequency or partial resection while preserving the mucosa.
- Internal valve: a spreader graft placed between the septum and the upper lateral cartilage widens the valve angle.
- External valve: a collapsing side wall is supported with a cartilage graft.
- Framework: in a crooked nose, osteotomies bring the nose back to the midline.
- Closure: dissolving sutures; silicone splints and an external splint if required.
What does the evidence say?
The NAIROS randomised controlled trial reported clearer improvement with surgery than with medical treatment in nasal obstruction due to a deviated septum. A meta-analysis using the NOSE score found a significant reduction in patient-reported obstruction after functional rhinoplasty, and a further meta-analysis reported improved quality of life.
These are group-level findings; the individual result depends on examination findings and the nature of the problem being treated.
Planning a visit from abroad
| Step | When | What happens |
|---|---|---|
| First contact | Weeks before | History, any previous CT scan or report shared; preliminary opinion |
| Arrival and consultation | 1 – 2 days before surgery | Endoscopic examination, valve manoeuvres, CT if needed, informed consent |
| Surgery | Day 0 | General anaesthesia; discharge same day or next morning |
| Follow-up | Days 1 – 7 | Silicone splints removed, saline rinses started, wound check |
| Departure | Day 6 – 8 | Flying is usually possible after the final check |
| Remote follow-up | Months 1 – 6 | Photographs and symptom reports at agreed intervals |
What does recovery look like?
The times below are typical ranges; they vary between individuals and are not a personal guarantee.
| Period | What to expect |
|---|---|
| First 48 hours | Congestion, slight oozing; breathing may temporarily feel worse because of swelling |
| Days 1 – 3 | Silicone splints removed, if used |
| Days 5 – 7 | External splint removed, if used; saline rinses for crusting |
| Days 7 – 10 | Return to desk work for most patients |
| Weeks 2 – 4 | Breathing becomes noticeably easier as swelling settles |
| Months 3 – 6 | Mucosal healing complete; result settles |
What are the risks?
The list below is not exhaustive; individual risks are discussed at the consultation and during the informed-consent process.
- Bleeding, infection, anaesthetic risks
- Crusting and temporary dryness
- Septal perforation
- Graft displacement
- Partial persistence or recurrence of obstruction
- Minor change in outer appearance
- Temporary change in the sense of smell
How is the decision made?
At the consultation the inside of the nose is examined endoscopically; the septum, turbinates and valves are assessed separately. Whether the side wall collapses on inspiration is checked with specific manoeuvres. A CT scan may be requested to image the sinuses and bony structures.
Once the structures responsible for the obstruction are identified, the scope of the operation, whether the outer appearance will be preserved and the expected recovery are discussed.
