How a breathing complaint and a shape complaint are examined together, what the septum contributes as both a structure and a graft source, and how combining the two changes the order of the operation.
Two complaints arrive in the same consultation more often than either one arrives alone. One is that the nose does not look the way its owner wants it to. The other is that one side of it has never moved air properly. Patients tend to raise the first and mention the second as an afterthought, sometimes only when asked directly.
They are not separate problems that happen to share an address. In a large proportion of cases they are two readings of a single structural finding, and the structure in question is the septum — the partition of cartilage and bone that divides the nose into two passages and, incidentally, holds up much of what is visible from outside.
This page is about what happens when both complaints are addressed in one operation: how the two examinations are conducted together, what the septum contributes in each of its two roles, and how combining the aims changes the order in which the work is done. The appearance of a nose that leans to one side — the cosmetic reading of deviation, and how a bone problem is separated from a soft-tissue one — is a different subject with its own page.
Functional rhinoplasty corrects a deviated septum and changes external shape in the same operation. The two aims are examined together because they frequently share a cause: a septum that obstructs airflow is often also the reason a nose looks crooked or a bridge sits off centre. The septum is simultaneously the structure being straightened and the preferred source of grafting cartilage, so the operative sequence has to establish the airway and the structural base before external shape is finalised. Whether any part of the treatment is covered by insurance depends on the diagnosis, the specific policy, and the insurer's own assessment — it cannot be stated in advance.

Why a breathing complaint and a shape complaint are examined together
The septum runs from the tip of the nose back towards the skull, a sheet of cartilage in front and bone behind. It divides the airway into two channels, and it also acts as the central strut that the bridge and the tip rest against.
When that sheet is not straight, both of its functions are affected at once. A deviation that bulges into one passage narrows it, and the narrower passage moves less air. The same deviation, if it sits far enough forward, pushes the external nose off the midline — visibly, in the form of a bridge that leans, a tip that points slightly to one side, or nostrils that are noticeably unequal.
This is why the two complaints are taken as one enquiry rather than two. A patient who says only "I want my nose straighter" is describing something whose cause may be entirely internal. A patient who says only "I cannot breathe through my left side" is describing something that may be visible on their face without them having connected the two.
Two things follow from this. The first is that a surgeon planning shape correction has a reason to ask about breathing whether or not the patient raises it. The second is that a correction addressing only the visible half — straightening what is seen while leaving the partition as it is — treats the symptom and leaves the structure.
What the examination records
The consultation records the two sets of findings side by side, because the plan depends on how they relate.
The breathing history. Which side is affected, whether it is constant or intermittent, whether it changes with position or with the seasons, and whether it has been present for as long as the patient can remember or followed an injury. Obstruction that alternates between sides through the day behaves differently from obstruction that is fixed, and the distinction matters because not all nasal blockage is septal. Swelling of the turbinates — the structures on the side walls of each passage — produces its own pattern, and allergic or inflammatory causes can produce blockage in a nose whose septum is reasonably straight.
The internal examination. The passages are inspected directly to see where the deviation sits, how far forward it extends, and what else is contributing. A deviation high and far back can obstruct considerably while barely showing externally. A deviation low and far forward may be visible from outside and yet obstruct relatively little.
The external assessment. Whether the bridge deviates, whether the tip is off centre, whether the two sides of the nose are asymmetric in width, and whether the deviation is a single continuous lean or a change of direction partway down.
The relationship between them. This is the finding that shapes the plan. If the external lean and the internal deviation point the same way and to a similar degree, one structural correction addresses both. If they disagree — a septum deviating to the right beneath a bridge that leans left — there is more than one thing going on, and the plan has to account for each.
What the CT contributes that an external view cannot
At Edition, 3D CT imaging (HDX WILL) is part of the assessment before nose surgery, and its contribution to the functional side of the diagnosis is different from its contribution to the cosmetic side.
What it shows is the shape of the airway and the partition through their full depth. A direct look into the nostril reveals the front portion clearly and progressively less of what lies behind it. The deviation that matters most for breathing is frequently not the part that is easiest to see.
Three things are read from it in particular.
The full extent of the deviation. Whether the septum bends at one point or curves along its length, whether the bony portion behind is involved as well as the cartilage in front, and whether there is a spur — a projecting ridge of bone or cartilage — pressing into the side wall.
The condition of the surrounding structures. The turbinates, the sinus openings, and the width of each passage at several points along its length. This is how a plan avoids the error of straightening a partition when the actual obstruction lies elsewhere.
How much cartilage the septum can spare. This is where the functional and the structural assessments meet, and it is discussed in the next section.
What imaging does not do is decide the operation. It describes what is there. The decision of what to correct, in what order, and how much to take remains a clinical judgment made with the patient's aims in view. A scan showing a deviation in a patient who breathes comfortably and likes the look of their nose is a finding, not an indication.
The septum's two jobs, and the tension between them
This is the part of functional rhinoplasty that is least often explained, and it governs more of the plan than anything else.
Septal cartilage is the preferred grafting material in nose surgery. It is straight, it is firm enough to hold a shape, it is the right thickness for building tip support and refining a bridge, and it is harvested through the same incision the surgery already uses — no second site, no separate scar, no additional recovery. When a plan calls for lengthening a nose, supporting a tip, or straightening a line, septal cartilage is generally the first material considered.
The tension is this. The same sheet that supplies the graft is the strut holding the nose up. Harvest too much and the support fails — the bridge can settle, the tip can lose its position, and in the worst case the middle of the nose collapses inward. Harvest too little and there may not be enough material to build what the shape correction requires.
So the plan works within a rule that is structural rather than negotiable: a supporting frame of cartilage is left in place along the top and the front of the septum, and only the portion behind and below that frame is available to be taken. How much that leaves varies from patient to patient, and it is one of the things the CT is read for before the operation rather than discovered during it.
Three consequences follow for a patient weighing a combined procedure.
- A deviated septum does not automatically mean abundant graft material. A septum that is bent may also be thin, previously injured, or partly ossified, and a bent sheet does not always yield straight pieces.
- Correcting the deviation and harvesting the graft are not the same act. Straightening frequently involves releasing, repositioning, and sometimes scoring the cartilage rather than simply removing the crooked part.
- If the septum cannot supply what the shape plan needs, the plan changes rather than the frame. Ear cartilage, rib cartilage, or dermis may be brought in. How those materials differ, and what each is chosen for, is covered separately in the page on Septal Cartilage, Rib Cartilage, Dermis: Choosing Among Three Autologous Materials.
How combining the aims changes the operative sequence
An operation addressing shape alone and an operation addressing shape and airway together are not the same operation with an extra step. The order of the work differs.
The septal work comes first. The partition is exposed, assessed directly, straightened, and — where the plan requires it — the available cartilage is harvested, with the supporting frame preserved. Everything that follows is built on top of what this stage establishes.
The reason for the order is straightforward. If external shape were finalised first and the septum addressed afterwards, the act of straightening the partition would move the base beneath the completed work. Correcting a deviation changes the position of the structures resting on it, which means shape decided before that correction is shape decided against a base that is about to shift.
Practical implications for the patient:
- The operation takes longer. Edition's stated range for nose surgery overall is 1.5 to 3.5 hours, and combined functional and aesthetic work sits towards the upper part of that range rather than the lower.
- The plan has a contingency built in. If the septum yields less usable cartilage than the imaging suggested, the surgeon needs an agreed alternative before the day, not a decision made mid-operation.
- Early recovery is not meaningfully different. Internal packing is removed at day 2 and sutures at day 14 for cases involving ear or autologous rib cartilage, on the same protocol as other nose surgery.
- Breathing does not improve immediately. Internal swelling after septal work obstructs the airway on its own account, and the passages can feel worse before they feel better. This is expected, and it is one reason the follow-up schedule runs to six months.
What functional correction does and does not promise
Straightening a septum addresses obstruction caused by the septum. It does not address obstruction caused by anything else, and this is where expectations most often go astray.
A nose can be blocked by turbinate swelling, by allergic inflammation, by nasal valve collapse — where the side wall draws inward on inspiration — or by a combination of several of these alongside a deviation. A patient with a deviated septum and untreated allergic rhinitis who has surgery for the deviation may find that a share of their blockage persists, because a share of it was never septal.
This is why the examination looks beyond the partition, and why a consultation that is careful about the airway will describe the expected improvement in terms of which component is being addressed rather than as a single figure. Nobody can quantify in advance how much easier breathing will feel.
What can be stated is the direction and the mechanism: a passage narrowed by a deviated partition will be wider once the partition is straightened, and how much difference that makes to a particular patient depends on what proportion of their obstruction the deviation accounted for.
The insurance question, answered honestly
Patients ask whether a functional component makes the procedure claimable, and the honest answer is that it depends on factors outside the clinic's control.
Edition's position on this is stated plainly: depending on the diagnosis, part of the treatment may be covered by indemnity insurance, and this varies according to the policy the patient holds and the insurer's own assessment. That is the whole of what can be said in advance.
It cannot be promised, because the clinic does not make the coverage decision. It also cannot be dismissed, because coverage does exist in some cases. What a patient can usefully do is establish the position with their own insurer before scheduling, taking the diagnosis into that conversation rather than a description of the surgery.
For international patients the question is separate again, since coverage arrangements differ by country and by policy, and treatment abroad is often handled under different terms entirely.
When the two are better separated
Combining is usual but not automatic. There are situations in which the two aims are better addressed apart, and a consultation that raises them is doing its job.
The clearest case is active inflammation. Operating on an inflamed or acutely infected nose invites problems that a delay of a few weeks avoids entirely.
The second is when the shape goal is substantial and the septum is already compromised — thin, previously operated on, or extensively deviated. Here the question is not whether both can be done but whether there is enough material to do both well, and the answer may be to source graft material elsewhere rather than to ask more of a septum that cannot give it.
The third is when the breathing complaint has not been properly attributed. If the obstruction may be predominantly allergic or turbinate-related, the useful order is to establish that first. Surgery aimed at a deviation that was not the main cause disappoints in a way that is difficult to undo.
Declining to combine is not a smaller version of the plan. It is a judgment that the sequence is wrong, and it is the same category of judgment as declining to operate at all — covered in the page on when a surgeon declines a first rhinoplasty.
Questions patients ask
If my septum is deviated, is my nose necessarily crooked?
No. A deviation sitting high or far back can obstruct significantly while the external nose looks straight. Conversely a nose can lean visibly for reasons that are not septal at all. The two are related often enough to be examined together and not so reliably that one can be inferred from the other.
Can the septum be straightened without changing how my nose looks?
Where the deviation is confined to the internal portion, correcting it need not alter the external appearance. Where the deviated segment is also part of what holds the visible nose in position, straightening it will change the outside to some extent — which is worth knowing before rather than after.
Will taking cartilage from my septum weaken my nose?
Not when a supporting frame is preserved. The rule is structural: the top and front portions stay, and only what lies behind and below them is available. Where the harvest would breach that frame, material is taken from elsewhere instead.
How long before I can tell whether my breathing has improved?
Longer than most people expect. Internal swelling obstructs the airway independently of the deviation, and it takes weeks to settle. Assessment of the airway forms part of the later follow-up visits rather than the early ones.
Does combining the two make the operation riskier?
It makes it longer and more complex, which is why the assessment beforehand is more detailed. The general risks of nose surgery — bleeding, infection, swelling, asymmetry, scarring — apply here as they do to any nasal procedure, and they are discussed individually rather than as a category.
What if the CT shows a deviation but I breathe perfectly well?
Then it is a finding rather than an indication. Many people have some degree of septal deviation without symptoms. If the shape goal does not require the septum to be straightened, and breathing is comfortable, there is no obligation to correct it.
