Barsky Glabellar Nasal Rasp, 18cm
$ 24.00
The Barsky glabellar nasal rasp works above the nose rather than on it, on the glabella, the bony ridge between the brows that runs down into the nasal root. It is 18cm long with a curved working face, so it reaches a surface that sits deep in the wound and curves in two directions at once, and it takes down a heavy brow ridge or a step at the radix that a straight dorsal rasp cannot properly touch. The same curve also makes it useful along the side of the dorsum, where a flat face would only ever meet the bone at one edge.

What a Barsky glabellar nasal rasp is
The glabella is the flat piece of bone between the eyebrows, and on some faces it stands proud enough that reducing the nose alone does not fix the profile. Lower the dorsum and leave the brow ridge where it is and the nose simply looks like it starts higher up. The Barsky glabellar nasal rasp is the instrument that deals with the other half of that problem.
It is 18cm long with a curved face, and both numbers matter. The length is what gets the working end up past the nasal root while the hand stays well outside the wound. The curve is what lets the face sit flat on bone that is convex in one direction and concave in the other, which is the shape the root actually is and the reason a straight rasp meets it at an angle.
Key design features
Curved for a surface that curves twice
The nasal root is a saddle: it falls away from side to side and rises from front to back. A flat face on a saddle touches at two corners. A curved face lies along the length of it and loads the whole working surface, which is the difference between shaving the root evenly and putting a flat spot in the middle of it.
18cm of reach
The glabella is the furthest point from the incision in a closed rhinoplasty, and a short instrument means a hand inside the field and a view of nothing. At 18cm the surgeon works from outside the nostril with the eye clear of the shank.
Cut teeth on a brow ridge
Glabellar bone is thicker and denser than the nasal bones below it, and a coated abrasive face on it is slow to the point of useless. Machined teeth are what actually reduce a brow ridge. The finish they leave matters less here than on the dorsum because the skin over the glabella is much thicker than the skin over the nasal bones.
The handle
Flat and wide. At the root the stroke is short and repeated rather than long and confident, because there is less room and less vision than anywhere else in the operation, and the handle is sized to hold the face at a constant angle through a dozen small pulls.
Which rasp reaches the glabella
Two instruments in our range are made for the glabella and they do different jobs. This table exists so the wrong one does not get ordered, because the names are nearly the same.
| What you are doing | The pattern for it | Why |
|---|---|---|
| Reducing a heavy brow ridge or a step at the root | This page, AO-12.09 | Cut steel teeth on a curved 18cm shank. Teeth are what actually remove dense glabellar bone |
| Smoothing the root once the bone is already down | the Peet Aufricht glabellar rasp, AO-09.08 | Diamond coated and curved. It abrades a few microns a stroke and will not catch, which is a finish rather than a reduction |
| Levelling the flat dorsum below the root | the McIndoe or the Maltz pattern | Straight faces for a straight surface. Neither will sit flat on the root |
| Following the dorsal curve in one pass | the Aufricht nasal rasp, AO-09.50 | Curved shank with three cut directions, for the dorsum rather than for the glabella |
Where it is used
It is bought as a nose instrument and used well beyond the nose, which is worth knowing before a set is priced.
| Procedure | What the Barsky glabellar rasp does there |
|---|---|
| Glabellar reduction | The primary use. Takes down a prominent brow ridge so the reduced dorsum runs into the forehead without a step |
| Rhinoplasty, nasal root | Reduces bone at the radix, the deepest point of the dorsal reduction |
| Rhinoplasty, lateral dorsum | Follows the curve at the side of the dorsum, where a flat face touches at one edge only |
| Frontal bone contouring | Reduction of the lower forehead, using the same curved face on a larger radius |
| After a nasal osteotomy | Smooths the peripheral bony edges once the mobilized bone is in position |
What it abrades, and what it must leave alone
The glabella sits between two structures nobody wants a rasp anywhere near, so this list is the most important table on the page.
| Tissue | What this rasp does with it |
|---|---|
| Glabellar bone and the frontal process | Removes. Denser than nasal bone and the reason for cut teeth |
| Nasal bone at the radix | Removes, in short strokes. Much thinner than the glabella directly above it |
| Nasofrontal suture | Approach with care. Short passes, and no working across the line of the suture |
| Periosteum and the thin envelope over the root | MUST BE LEFT ALONE. Raise the flap first and keep the teeth on bone |
| Medial canthal attachments and the trochlea | Never. They sit either side of the root, and the stroke is planned so the face stops on bone |
How it compares with the other finishing surfaces
The honest comparison is between this and the diamond coated glabellar rasp, because those two are the pair that get confused at the order stage.
| Instrument | What it does at the glabella | When it is the right choice |
|---|---|---|
| Barsky glabellar, cut teeth, as here | Removes dense bone at a working rate, and leaves ridges | Reduction. When there is a real brow ridge to take down |
| Peet Aufricht glabellar, diamond coated | Abrades a few microns a stroke and cannot catch | Finishing. When the bone is already the right height and the surface is not |
| A straight dorsal rasp | Meets the saddle of the root at an angle and digs at one edge | Never at the root. Right for the dorsum below it |
| An osteotome | Cuts rather than abrades, in one committed pass | When the bone has to be divided rather than reduced |
Materials and finish
Every Barsky glabellar nasal rasp we make is cut from high quality medical grade stainless steel. The steel itself is made to a German specification. We do not publish a grade number, because the number on a certificate tells a surgeon nothing about how an abrasive face holds up after fifty autoclave cycles, and the answer to that is in the finish rather than in the alloy.
Teeth are machined into the curved face rather than applied to it, so nothing sheds and nothing is plated to chip. The body is passivated and satin finished so it throws no glare. On a curved face the teeth at the apex of the curve do most of the work and wear first, so check the middle of the face rather than the ends when deciding whether an instrument is still cutting.
Caring for it
Rinse it before the trolley is cleared. On a curved toothed face the debris collects on the inside of the curve, which is the last place a straight brush reaches and the first place bone paste sets hard.
Work a soft nylon brush along the teeth and into the curve, in the direction the teeth lean, never against them and never with wire. Enzymatic cleaner, ultrasonic cycle, deionized water rinse, dry fully, autoclave at 134 degrees Celsius. Store it with the face resting against nothing.
Ordering and wholesale
The Barsky glabellar nasal rasp is made in our own workshop and sold direct, which is why the price sits where it does against the catalogue houses. Order one for a single set, or in quantity for a hospital list or a distributor line; we do OEM work under your own brand and your own item numbers, and we will hold a run to your pattern rather than ours if you send a sample. Stock items ship from our own workshop. Backorder items take 10 to 12 working days to make. Every instrument carries a three year replacement warranty against manufacturing defects. Production is controlled under an ISO 13485 quality management system.
Frequently asked questions
What is a Barsky glabellar nasal rasp used for?
Reducing bone at the glabella, the ridge between the brows, and at the nasal root just below it. It is used when lowering the dorsum alone would leave the profile stopping in a step, and it is a reduction instrument rather than a finishing one.
Where is the glabella, and why does it need its own rasp?
It is the flat bone between the eyebrows, above the nasal root. It needs its own rasp for two reasons: it is the furthest point in the wound from a closed incision, so the instrument has to be long, and it curves in two directions at once, so a flat face cannot lie on it without digging at one edge.
How is this different from the Peet Aufricht glabellar rasp?
Teeth against grit. This one has machined steel teeth and removes dense glabellar bone at a working rate. The Peet Aufricht is diamond coated and takes off a few microns a stroke. Use this to reduce a brow ridge and that one to smooth what is left behind.
How long is the Barsky glabellar nasal rasp?
18cm. The length is what lets the working face reach past the nasal root while the hand and the surgeon’s line of sight stay outside the nostril.
Can it be used anywhere other than the nose?
Yes. The same curved face is used for frontal bone contouring and for smoothing peripheral bony edges after an osteotomy. Anywhere a curved bony surface has to come down and the skin over it is thick enough that a toothed finish is acceptable.
