The tip — Resection, sutures and support, in that order
The tripod as a working model, cephalic resection and how much to leave, the complete catalogue of shaping sutures with their typical errors, the difference between columellar strut and septal extension, and deprojection techniques.

Key points
- The tip is the most difficult element in all nasal surgery, and not only technically: its healing is so slow that the definitive result appears only months or years later.
- The long-term result depends on preserving the support mechanisms, not on the manoeuvre that looked good in theatre. Everything divided must be restored.
- The working model is still the tripod: two lateral legs — the lateral crura — and a medial one — the conjoined medial crura. Shortening or lengthening a leg changes rotation and projection predictably.
- Almost always prominence depends more on lateral crural convexity than on its size: properly trimming the cephalic border usually suffices to reduce projection and bulk without touching support.
- The columellar strut and the septal extension graft are not the same, and confusing them is a costly mistake: the first anchors only to the medial crura, the second to the septum and through it to the nasal spine.
What determines what
Before choosing a technique it helps to be clear about which structure governs each parameter, because that is what prevents operating on the wrong place. Tip height and width depend on the height and width of the alar dome and on the degree of opening of the cartilaginous dome — the domal divergence angle. Projection is determined by columellar length — intermediate and medial crura — the anterior nasal spine and, to a lesser degree, the cartilaginous dorsum. And rotation depends on the columellar plane and its relation to the caudal septum. On that basis, most procedures consist of shaping the lower lateral cartilages: altering their size, shape, position and strength so that it translates into a change in external appearance. There are techniques to spare — resection, incisions, sutures, grafts — but what is decisive is the prior diagnosis, not the catalogue.
The skin modulates everything done beneath it
No less important than the anatomical diagnosis is the relationship between cartilage strength and skin thickness, because the response to any manoeuvre depends on it. A domal suture that elegantly defines the tip in thin skin does not show through thick skin at all and the patient sees no change. Conversely, a graft that adds definition in thick skin becomes visible at six months in thin skin as a discernible edge. In broad tips with thick skin, lipectomy of the subdermal fibrofatty tissue is often needed to thin it, or a graft that increases projection and by contrast produces a finer tip. That debulking has reasonable detractors: it generates more inflammation and more scarring in the tip, and with it a risk of supratip fullness. As with so much here there is no single answer; what does not work is doing it without deciding.
Three levels of difficulty
- LowCephalic resection of the lateral crus + columellar strut + intradomal and interdomal sutures + tip repositioning suture. This resolves most tips without structural pathology
- MediumAdd crural modification with equalising sutures — lateral crural steal, medial crural overlay — which correct asymmetries and achieve a more defined, symmetrical tip
- HighAdd cartilaginous definition grafts — shield type and derivatives. This is the level demanding most judgement, because the graft that defines today is the one that shows through tomorrow
Cephalic resection: how much to leave
This is the near-routine manoeuvre of the tip, and also the one that has historically produced the most sequelae. The classic rule is to leave about 6 mm of the caudal portion of the alar cartilage, avoiding excessive excision of the dome that produces the collapsed tip. In current practice the figure has crept upward: it is usual to measure 8 mm at the point of maximum width and draw the resection line from there towards the dome, and some leave even more, resecting only enough to keep the lateral crus from contacting the upper lateral, on the grounds that resecting a lot leaves small, characterless noses. The prudent approach is a two-figure rule — of the order of 6 mm at the dome and 8 mm posteriorly — and not carrying the resection too far back along the alar. The resected fragment is not discarded: it is autologous cartilage, already shaped, perfect for tip grafts.
The lateral crural steal
When more rotation and more projection are needed at once, the manoeuvre is to move the dome laterally: mark where the new dome should sit — more lateral than the original — and suture it there, so that length is "stolen" from the lateral crus and given to the medial one. In tripod language, the medial leg is lengthened at the expense of the lateral ones: the tip rises and comes forward. It combines naturally with cephalic resection, drawn from the point of maximum width to the old dome. A practical detail that saves trouble: elevate the perichondrium of the middle crus at the mucosal level before suturing, so it does not fold and interfere with the new dome. Fixation is two 5/0 PDS stitches — the cephalic intradomal simple, the classic intradomal a mattress — and the knot must always lie medially, where it is neither palpable nor visible.
The shaping sutures and what each is for
| Suture | What it joins | Effect |
|---|---|---|
| Intradomal (transdomal) | The two limbs of the same dome | Reduces the domal angle: narrows the dome and increases projection. It is the suture that creates definition |
| Interdomal | The two domes to each other | Closes the domal divergence angle and refines broad tips — ball, boxy or bifid. It also increases projection |
| Intercrural (medial) | The medial crura or their footplates | Narrows the columella or its base and stiffens it. A side-to-side stitch at the nostril rim collapses the typical columellar bulge |
| Intra-alar (deconvexing) | The two borders of the lateral crus over its point of maximum convexity | Controls lateral crural convexity. Indicated in the three Bs: broad, boxy, ball. A 5/0 PDS mattress without penetrating mucosa |
| Inter-alar (alar spanning) | The two lateral crura, passing through the anterior septal border | Refines the whole and rotates the tip. Passing through the septum it creates the supratip breakpoint and prevents alar malposition and pinching |
| Caudal septal fixation (tongue-in-groove) | The medial crura to the caudal septum, as a transmucosal mattress | Alters the columellar plane: it rotates the tip, secures the position and prevents columellar descent over time |
The four errors of the domal suture
This is the suture that gives the most result and also spoils the most, and its failures are four and easy to name. Too tight: a sharp, pinched tip with the operated look everyone recognises. Too loose: no definition, it achieved nothing. Too medial: no effect at all, because it is not over the real dome. Too lateral: it overprojects the tip. The interdomal fails in two directions the same way: too tight gives a pointed tip, too loose a wide one. Numbers help: the domal divergence angle should end up around 30°, and both domes should measure the same — of the order of 5-6 mm — something worth checking with callipers rather than by eye. And one global proportion that orders the whole: tip width should be 1:1 or at most 1:1.2 relative to the dorsum, the tip always slightly wider.
Columellar strut and septal extension are not interchangeable
The columellar strut is a cartilage fragment — of the order of 30 × 3 mm, from septum or resected dorsum — housed between the medial crura and fixed only to them, never to the septum or the nasal spine. It unifies the tip complex, shapes and symmetrises the columella and adds stiffness. What it does not do, and this is the point: it does not guarantee projection or rotation. The study that examined it in a controlled way found that placing it may alter neither, and can even derotate the tip. The caudal septal extension graft is a different thing: it is sutured in continuity with the septum, which in turn rests on the nasal spine, so it inherits that support and does control projection and rotation stably. The mental rule is simple: if real, durable support is the aim, the graft must reach the septum.
A suture sequence that works
- 1. Create the domesEversion stitches at the marked position, entering medial-inferior and returning lateral-superior. Two per side usually suffice, and never in the most lateral part, which would drop the tip
- 2. Prepare the supportCut the septal extension measuring the height and projection sought. As a reference, about 2-3 mm higher than the septum and 1 mm more caudal projection; if the tip tends to collapse, slightly more
- 3. Fix itTransfix extension and septum with a fine needle acting as a temporary axis and then place the mattress stitches. Watch where the tip ends up: the cartilage’s own curvature deviates it
- 4. Join the domesCheck with callipers that both measure the same and place two interdomal stitches on the medial and cranial aspect of the new domes
- 5. Anchor to the septumAlar spanning for the lateral crura over the dorsal septum, and tongue-in-groove for the medial ones over the caudal septum, the latter as endonasal as possible so as not to retract the columella
- 6. Restore ligamentsIf ligamentous preservation was chosen, suture the scrolls and the superficial Pitanguy ligament before closing. Pass Pitanguy beneath the interdomal stitch and fix it to the septum first, which is more stable
When there is too much projection
| Technique | How | What to bear in mind |
|---|---|---|
| Medial crural overlay | Mark the zone 8 mm from the new dome and divide so that a medial segment lies under a lateral one, overlapping 3-4 mm and fixed with a 5/0 PDS mattress | It derotates and deprojects: tip downward. Also useful when the medial crura differ markedly in length. It widens the columella, so it sits badly with reinforced extensions |
| Telescoping of the medial crura | Division of the medial crura and introduction of the anterior portion between the two limbs of the posterior portion | It requires the transcolumellar route and relies heavily on a columellar strut. It is the option for significant overprojection |
| Alar flip | Division lateral to the domes of the alar crura, fully released from their mucosal lining and their lateral attachments to the sesamoid cartilages | Reserved for exaggerated concavity of rigid alar cartilages, a problem hard to solve by other means |
The musculature, almost always forgotten
- The depressor septi nasi is the decisive muscle: when its pillars are short and hypertrophic, the tip drops on smiling. Dividing it at the nasal spine is one more manoeuvre to elevate the tip.
- The levator labii superioris alaeque nasi acts synchronously with it and accentuates its effect, so treating only one of the two leaves the problem half solved.
- The Pitanguy ligament plays a notable role in some ptotic tips: treating it releases the tip and produces slight upward rotation with increased projection.
- If the nose arrives with the caudal septal edge untouched, this is the moment: the straighter it is left, the more rotation. It is the manoeuvre that sets the nasolabial angle before anything is fixed.
The tip in secondary rhinoplasty
In an already operated nose, removing fibrosis is a fundamental step, not a formality. Fibrosis is always present, but sometimes it is so marked that it gives not only exaggerated bulk but true deformity, especially in the tip and supratip. At the same time it pays to open with realistic expectations: at best that fibrosis will be found along with remnants of previous grafts that may be useful for reconstruction; at worst, solid or injectable non-resorbable implants that have destroyed the tissues. It is worth telling the patient beforehand, because it changes the plan and sometimes the number of stages. And one rule that avoids regret with refinement grafts: if after placing it doubts remain about its final effect, it is better to remove it.
