The word arrives before the shape does. Aquiline is an adjective borrowed from the eagle, and the pages that use it rarely stop to define it. They show a profile with a bridge that bows outward and call it aquiline, Roman, hawk or hooked, sometimes all four.
This page keeps the bridge and the hook separate. It looks at what nine pages agree on, where the names part, what the measurements can and cannot record, and why a single word can describe a bump on the bridge, a downward tip, or both. It does not rank the shape or compare treatments.
What aquiline means
Aquiline is an adjective before it is a nose type. Dictionary.com defines it as "shaped like an eagle's beak; hooked" and traces it to Latin aquila, eagle. The nose pages use it for a bridge that rises in a curve or arch, read from the side.
Nine consumer pages published between March 2024 and October 2026 were read for this page. All nine put the bridge first. Some call it prominent or high; others call it curved, arched or slightly hooked. The dated table in section six keeps the individual wordings and dates. What matters here is the shared part: the line of the bridge, not the size of the whole nose.
That list is the shared part. The label describes the line of the bridge, not the size of the whole nose: the pages call the bridge prominent or high, not the nose large, and none prints a length or a width. It also does not describe one single hook. The next section separates a bump on the bridge from a tip that points down, because the pages do not treat those as the same thing.
Five of the nine pages also call the shape a Roman nose. Three keep the two names apart. One keeps aquiline apart from both Roman and hooked. The boundary is a naming convention, not a measurement, and the next sections show where the lines fall.

The hook: a bridge curve, a tip direction, or both
In the nine pages, "hook" is used at two different places. On the bridge, it means a bump or an arch: the bridge line bows outward instead of running straight. At the tip, it means the tip points downward rather than straight ahead or up. A profile can have either one without the other, which is why a page can use the same word for two different readings.
The clearest split is between a bridge curve and a tip direction. The French surgeon's page says the aquiline hump is more pronounced and the bridge line forms a continuous curve; it gives the clearly downward-pointing tip to a separate hooked entry. A London clinic goes the other way: its hooked entry, which it also calls aquiline or hawk, has a high bridge that curves outward and a tip that points slightly downward. A surgeon's page in Spain gives aquiline, Roman and hooked separate entries and gives the drooping tip to the hooked one. A hospital page puts the arch or hook on the bridge. A clinic page says the aquiline profile is curved or slightly hooked without naming the tip at all.
The word "prominent" belongs to the bridge in these sentences. None of the pages defines the label by overall nose size, and none prints a length or a width that would separate a small nose from a large one. The shared reading is therefore narrower than the everyday phrase: a bridge that bows outward, with the tip and the hook left as separate notes.
This is also where a front photograph runs out. A front view can show the width of the nose and the shape of the tip, but it cannot show whether the bridge line is straight, concave or convex. The dorsum is a profile reading. A page that claims to identify an aquiline nose from the front alone is describing the tip or the width, not the bridge.
Aquiline and Roman: the same bridge, two names
On this page's nine aquiline pages, five use Roman as another name for the same profile: Belorens, Eastern, Seckin, Yunus and Tabeebo. Three keep the names apart: Berkeley, Djian and Acibadem. One, Sordo, gives aquiline, Roman and hooked separate entries. That is a different count from the Roman page in this series, which read nine pages that mention Roman and found four synonyms, four splits and one Roman-only page. The samples overlap but are not identical, so the counts are not supposed to match; neither count is a vote.
Where the names are synonyms, the pages describe one bridge with two words. Belorens, Eastern, Seckin, Yunus and Tabeebo all put a prominent or high bridge first and add a curve, arch or hook; none adds a second measurement or a cutoff. The dated table keeps their individual wordings, and the Roman page quotes them from the other direction.
Where the names are kept apart, aquiline is usually the more arched end. Djian gives Roman a slight bump without a marked tip curvature, aquiline a more pronounced hump and a continuous bridge curve, and hooked a clearly downward tip. Berkeley puts Roman and the hooked or hawk nose in separate entries and uses aquiline as another name for the hawk. Acibadem does the same: the hawk, also known as aquiline, has a high bridge with a noticeable arch or hook, while Roman is a separate entry. Sordo separates all three and gives the drooping tip to the hooked entry alone.
No page prints a degree or a millimetre where the names part. A reader who sees "aquiline nose roman" in a search box is therefore looking at a naming question, not a measurement question. The useful move is to ask which page is being quoted: a page that treats the names as synonyms is describing one profile with two words; a page that separates them is usually putting aquiline at the more arched end, but it does not give a boundary that can be checked.
What "aquiline features" does and does not mean
The dictionary definition is about shape, not ancestry or character: shaped like an eagle's beak, hooked, from the Latin word for eagle. That is the whole etymology used here. It does not imply a temperament, a region of origin or a state of health.
The nine pages describe a nose, not a face. None of them uses the phrase "aquiline features"; they list the bridge, the tip, the hump and the profile. When the phrase appears in ordinary writing, it applies the nose adjective to a person's features as a whole. That is a wider description, but it is not a second classification: the pages read for this page supply no measurement, cutoff or category for a face-wide aquiline type.
It is also not a diagnosis. One of the nine pages says outright that neither Roman nor aquiline is a formal medical diagnosis, and the three measurement papers read for this page do not use either label as a category. A clinician may describe a specific nasal deformity in a consultation, but that is a different context with a different vocabulary. The consumer label does not carry a diagnosis, a severity grade or a treatment plan.
The practical boundary is narrow. Use the phrase for a profile whose bridge bows outward in a curve or arch. Do not use it to claim a person's origins, personality or health, and do not treat it as a condition that needs to be corrected. The pages themselves do not make those claims.
How to read the profile
A profile photograph can answer two questions separately: does the bridge line bow outward, and which way does the tip point? The pages read for this page answer the first consistently and the second inconsistently, so it helps to record them in separate columns instead of folding them into one label.
The three measurement papers do not use the aquiline label. A 2011 lateral-view study of 105 adults classed the dorsum as straight, concave or convex; convex is the class closest to the consumer descriptions. A 2021 CT study of 134 patients found a hump in 67 of them, with a mean height of 1.8 mm (range 1.1 to 3.8 mm) and a mean length of 17 mm (SD 2.7 mm). A 2016 study of 60 rhinoplasty candidates and 60 matched controls defined the nasolabial angle and reported a cited band of 90 to 115 degrees, with means of 100.22 and 101.76 degrees in its two groups. None of the three supplies a cutoff for the word aquiline.
A practical way to record what the pages describe, without pretending a phone photo is a clinical scan:
Four readings, what each one records, and the numbers the sources actually print. Only the last row is a fixed angle; the first is a class, and the middle two are millimetres from one CT sample.
| Reading | What it records | Reference points | Numbers in the sources |
|---|---|---|---|
| Dorsum profile class | Whether the bridge line is straight, concave or convex in a lateral view | Profile photograph or lateral view, radix to tip | Three classes; no millimetres or angles |
| Hump height | How far the bump rises above the surrounding dorsum | Midsagittal CT; hump apex | Mean 1.8 mm; range 1.1 to 3.8 mm |
| Hump length | How far the bump runs along the dorsum | Midsagittal CT; along the nasal dorsum | Mean 17 mm; SD 2.7 mm |
| Nasolabial angle | Tip rotation relative to the upper lip | Columella and upper lip | Cited band 90 to 115 degrees; means 100.22 and 101.76 degrees |
The dorsum classes come from a 2011 study of 105 adults; the hump dimensions from a 2021 CT study of 134 patients, 67 with a hump; the angle band and means from a 2016 study of 60 candidates and 60 controls. None of the three uses the aquiline label, and none gives a cutoff for it.
- Take the profile at nose height, with the head in a natural horizontal gaze. A phone held at arm's length tilts the view and changes the apparent bridge line.
- Mark the radix, the dip between the brows, and the tip. Hold a straight edge between them. Is the bridge above the line (convex), on it (straight) or behind it (concave)? This is the three-class reading, not an angle.
- Note where the highest point of a bump sits: the upper, bony part of the nose or the lower, cartilaginous part. A photograph can show the level; it cannot confirm what lies underneath.
- Record the tip direction on its own: draw the angle between the columella and the upper lip. The cited nasolabial band is 90 to 115 degrees, but a phone photo is not a cephalogram and the angle is sensitive to head tilt.
- Write the two readings in words. A convex bridge with a straight tip is a different profile from a straight bridge with a downward tip, even if both get called hooked in conversation.
A dated comparison of definitions
The table orders twelve published positions from September 2011 to October 2026: three measurement papers and nine consumer pages. The third column records what carries the definition; the fourth records the hook or the tip; the fifth records whether any number is printed. The counts in the text come from the nine consumer rows, not from the three measurement papers.
The table is not a tally. A count of pages cannot settle a definition, and a later date is not a tighter one. What the table can show is that the bridge is the shared part, that the names and the hook are not shared, and that the measurable readings exist without being the label.
Twelve positions, ascending by publication day: three measurement papers and nine consumer pages. The third column is what carries the definition; the fourth is the hook or tip; the fifth is the number printed. No consumer page prints one.
| Published | What it is | Definition rests on | Hook or tip | Numbers printed |
|---|---|---|---|---|
| 1 September 2011 | Measurement paper, lateral-view rhinometry, 105 adults | Does not use the label | Dorsum classed straight, concave or convex; no tip direction | No millimetres or angles |
| 24 February 2016 | Measurement paper, 60 candidates and 60 controls | Does not use the label | Nasolabial angle measured; no aquiline category | NLA band 90 to 115 degrees; means 100.22 and 101.76 |
| 1 September 2021 | Measurement paper, CT, 134 patients, 67 humps | Does not use the label | Hump on the dorsum; tip not classified | Hump 1.8 mm high (1.1 to 3.8), 17 mm long |
| 22 March 2024 | Consumer page, clinic | Prominent high bridge and downward curve; aquiline as Roman synonym | A downward curve; tip not separated from the bridge | None |
| 24 September 2024 | Consumer page, clinic | Prominent bridge, slightly curved; aquiline as Roman synonym | No tip direction | None |

| 24 August 2026 | Consumer page, surgeon | Curved shape and prominent bridge; aquiline separate from Roman and hooked | Drooping tip belongs to the hooked entry | None |
| 15 October 2026 | Consumer page, clinic | Prominent bridge, straight-to-convex; curved or slightly hooked emphasis | No tip direction; neither name is a formal diagnosis | None |
Publication dates, with later revisions kept out of the sort: Belorens revised 10 May 2025; Berkeley Square 22 October 2026; Dr Seçkin Ulusoy 13 October 2026; Dr Jérémy Djian 14 July 2026; Acibadem 7 June 2026; Gustavo Sordo 7 October 2026. The three measurement papers do not use the aquiline label as a category. A Europe PMC phrase search on 23 October 2026 returned 94 records for aquiline nose and 168 for nasal tip rotation; the first ten aquiline records sampled include case reports on pycnodysostosis and thyroid disease, a history paper and a methodology piece, not a classification with a cutoff. No consumer page in the table prints an angle, a ratio or a millimetre.
The label is useful as a starting description and weak as a boundary. It points to a bridge that bows outward, and that is the part all nine pages share. The hook is a second question: it can sit on the bridge, at the tip, or in both places, and the pages disagree about which one the word covers.
The measurements are separate from the name. A lateral-view class, a hump measured in millimetres on CT, and a nasolabial angle can all be recorded, but none of the sources turns them into a cutoff for aquiline. Reading the bridge and the tip as two notes is more useful than choosing between Roman, hawk and hooked.
Questions this page answers
What does an aquiline nose look like in profile?
It looks like a bridge that rises in a curve or arch above the line from the brow to the tip. The nine pages read for this page all describe the bridge this way; the tip may be straight, slightly down or upturned. A single bump on the bridge and a downward tip are both called a hook in ordinary speech, but the pages do not agree on whether the hook belongs to the bridge or the tip.
Is an aquiline nose the same as a Roman nose?
It depends on the page. Five of the nine pages read here use the two names as synonyms; three keep them apart and usually make aquiline the more arched version; one gives aquiline, Roman and hooked separate entries. No page prints a cutoff where one becomes the other, so the answer is a naming convention, not a measurement.
Does an aquiline nose always have a hooked tip?
No. The shared feature in the nine pages is a curved or arched bridge, not a downward tip. One page attaches a slight downward tip to its aquiline and hawk entry; another reserves the clearly downward tip for a separate hooked entry; several say nothing about the tip at all. Read the bridge and the tip as two separate notes.
What does the phrase aquiline features mean?
It applies the adjective for a hooked, eagle-like nose to a person's features as a whole. The nine nose pages read here do not use the phrase and do not define a face-wide category; they describe the bridge and the tip. It is a descriptive phrase, not a diagnosis or a classification with measurements.
How can an aquiline nose be measured?
There is no measurement for the label itself. The closest readings are the dorsum profile class (straight, concave or convex), the height and length of a hump on CT, and the nasolabial angle for tip rotation. The papers that define those readings do not use the aquiline label, and no consumer page prints an angle or a millimetre.
Is an aquiline nose a medical diagnosis?
No. One of the nine pages says outright that neither Roman nor aquiline is a formal medical diagnosis, and the three measurement papers read here do not use either term as a category. A clinician may describe a specific nasal deformity in a consultation, but that is a different context from the consumer label.
