The short answers

Where the incisions go: Inside the nostrils onlyNo external scar. The open approach adds a short cut across the columella, the strip of skin between the nostrils.
Compared with open: No significant differenceA 2025 systematic review and meta-analysis pooled 12 studies and 1,067 patients. The split was 539 open and 528 closed.
Operating time: Typically 1.5 to 3 hoursNHS figure for nose reshaping. The pooled analysis found no significant difference in operative time between the approaches.
Anaesthesia: Usually general anaesthesiaThe NHS describes nose reshaping as normally performed with the patient asleep.
Splint: Taped on for 7 daysNHS guidance describes a splint taped over the nose and kept dry until it is removed.
Certainty of the comparison: Substantial heterogeneityThe review's authors reported substantial statistical heterogeneity and advised tailoring the choice to the anatomy and the surgeon.

Closed rhinoplasty reaches the nasal bones and cartilages through incisions hidden inside the nostrils. The open approach reaches the same structures, adding a short cut across the columella so the framework can be lifted and seen directly.

Patients often arrive convinced that one route is modern and the other outdated. The pooled evidence does not support that. It is a decision about access, and it is made from what a particular nose needs.

What the closed approach is

Every incision sits inside the nostril, so the nose carries no visible external scar afterwards. The septum, the tip cartilages, the bone and any grafting are otherwise the same operation reached by a different route.

What is traded is exposure. Closed access reaches the framework indirectly, which makes delicate interdomal suturing and nuanced grafting more technically demanding.

Surgery is normally performed under general anaesthesia. The NHS states that nose reshaping can take 1.5 to 3 hours, whichever approach is used.

What the pooled comparison found

1,067

patients pooled in a 2025 systematic review and meta-analysis of open versus closed rhinoplasty

539 open and 528 closed, across 12 studies.

The review found no statistically significant difference on any measure it compared. Those measures included aesthetic outcome scores on the ROE questionnaire, breathing scores on the NOSE scale, swelling, bruising, operative time, satisfaction and complications.

That is a group finding, not a prediction for one nose. The authors reported substantial statistical heterogeneity, so the pooled average smooths over real differences between the studies it drew on.

The two groups were probably not equally difficult either. Surgeons choose open access for harder noses, so no significant difference across mixed cases does not make the choice irrelevant in a particular nose. The open versus closed comparison sets out the trade-offs measure by measure.

Which noses the closed approach suits

Closed access suits more contained changes to a sound framework: a dorsal hump reduction, modest tip refinement or straightforward septal correction.

Standard reference material lists open access as commonly selected for complex tip work, marked asymmetry, structural grafting and most revision surgery. A small, limited revision can sometimes be done closed.

Reference material also lists more marked and longer lasting swelling as a disadvantage of the open approach. The pooled analysis still found no statistically significant difference in swelling or bruising between the two.

How the approach should be chosen

Ask which approach the surgeon would use on your nose, and why. The answer should describe findings from examining you, not a house style.

One approach for every nose

A surgeon who applies the same approach to every nose, or cannot explain why, is telling you something. Ask which approach they would use for your nose and what makes it the right one. Our doctors answer that in writing.

Neither approach is a guarantee. Reference material quotes revision rates of up to 15 per cent and complications of around 3 per cent. Those figures describe the operation rather than the route into it, and published rates vary with how a revision is defined.

Risks the approach does not remove

The NHS lists breathing difficulty that is usually temporary but occasionally permanent. It also lists a stiff and numb nose, nosebleeds, damage to the cartilage wall between the nostrils and an altered sense of smell.

Infection, and excessive bleeding.
Blood clots, and a reaction to the anaesthetic.

The pooled comparison found no significant difference in complications, so keeping the incisions inside the nostrils does not remove these risks. Avoiding the columellar scar is the one thing the closed approach reliably does.

Questions to ask a surgeon

Take these to a consultation. The consultation checklist is built to be printed and written on, and our doctors will answer questions sent through the site before you travel.

Which approach would you use on my nose, and which findings on examination make that the right one?
How often do you use the closed approach, and what would make you change to open once you had started?
If grafting turns out to be needed, can you place it through a closed approach, or would that change the plan?
What would be harder to achieve through a closed approach in my case, and what would that cost me?
If a revision were ever needed later, would it have to be done open?
