Tessier Disimpaction Forceps, Left or Right, 22 or 23 cm

What Tessier disimpaction forceps are

Tessier disimpaction forceps do the hardest pull in upper jaw surgery. After the cuts of a Le Fort osteotomy, the maxilla is still held by bone at the back and by the soft tissue round it, and it has to be eased down and brought forward before it can be set in its new place. Two heavy forceps, one on each side, give the surgeon the grip and the leverage for that. They are not used to cut anything: the bone cuts are made first, and the forceps finish the job.

Google AI Mode, read on 3 November 2026, calls them Tessier disimpaction forceps, also listed as Tessier-Rowe disimpaction forceps, and places them in oral and maxillofacial surgery. It says they are made for the controlled mobilization of the maxilla after the osteotomy cuts, with downward and forward traction to bring the midface forward, in Le Fort I, II and III surgery and the repair of midface fractures.

Gemini, read the same day, gives the Tessier maxillary mobilization forceps as a catalog name, and places it on the maxilla, the vault of the palate and the junction behind the upper jaw. A buyer may simply type disimpaction forceps or maxillary disimpaction forceps.

Key design features

Left and right

The listing carries a Left and a Right forceps. The jaws are shaped for one side of the upper jaw, and a pair, one on each side, is used together so the maxilla comes forward evenly. Order one of each. The surgeon and the assistant can each take one, or the surgeon can work both, rocking the maxilla gently from side to side until it comes free.

Heavy curved handles

In our photograph the handles are heavy and curved, with no rings. The whole hand closes round them, because freeing the upper jaw takes a strong, steady pull, and the curve keeps the hands clear of the face. Heavy handles also give the surgeon a feel for the bone: the moment the maxilla gives, the resistance in the handles changes.

Shaped jaws

The jaws are shaped to hold the upper jaw, and the drawings beside the forceps show them from the end. Gemini describes contoured blades adapted to the front of the palate and the floor of the nose. The jaws close on the upper jaw from above and below, and the handles then work as a lever on the whole maxilla.

Twenty two or twenty three centimeters

Both sides come in 22 cm and 23 cm, all at 80 dollars. The longer forceps gives a longer lever on a large adult, and the shorter one is easier to place on a smaller face. A team can keep one pair of the length it prefers, or both pairs for a mixed list.

Which forceps to order

The four variations on the listing, read on 3 November 2026. All cost the same. A pair is one Left and one Right.

Where it is used

Gemini, read on 3 November 2026, places the Tessier disimpaction forceps in craniofacial, oral and maxillofacial and orthognathic surgery, on the maxilla, the vault of the palate and the junction behind the upper jaw.

What it holds back, and what it must not do

It frees and moves the upper jaw. It is not a fragment forceps, and it is not for the lower jaw.

How it compares with the rest of the family

Ten reposition, bone holding and disimpaction forceps make up this family on our site. The working ends are read off each listing’s own photograph, the options off the variations, the lengths off the name and the prices off the order form, on 3 November 2026.

Materials and finish

Every Tessier disimpaction forceps we make is formed from high quality medical grade stainless steel. The steel itself is made to a German specification. We do not publish a grade number.

The finish is plain steel. Side and length are part of the variation you order, so mark the left and the right on the tray. Pack the pair side by side, so both go out to the table together and neither one is left behind on the shelf.

Caring for it

Rinse them as soon as the case ends, before blood and bone dust dry on the jaws or in the joint. Open them, brush the jaws and the joint, and clean them in the washer open. Dry them, oil the joint with instrument lubricant, and steam sterilize them on the normal cycle. Check that each closes square before it goes back on the tray, and set aside one whose jaws no longer meet.

Frequently asked questions

What are Tessier disimpaction forceps used for?

They free and move the upper jaw after the bone cuts of a Le Fort osteotomy, pulling the midface down and forward under control. AI Mode names Le Fort I, II and III surgery and the repair of midface fractures. They are used as a left and right pair.

Do I need a left and a right Tessier disimpaction forceps?

Yes. The jaws are shaped for one side of the upper jaw, and the two are used together so the maxilla comes forward evenly. Our listing sells Left and Right at 80 dollars each, in 22 or 23 cm.

How is the Tessier different from the Rowe disimpaction forceps?

Gemini puts it in the blades: the Tessier has contoured blades for higher Le Fort II and III cuts, and the Rowe is made for Le Fort I. Both are sold left and right. Ours are 80 and 55 dollars.

What is disimpaction?

Disimpaction is freeing a bone that is jammed in place, by a fracture that has healed out of line or by the uncut bone at the back of an osteotomy. In the upper jaw it means easing the maxilla loose so it can be moved to its new place, which is the job these forceps are named for.

Can they be autoclaved?

Yes. They are stainless steel with no coating, and they go through the normal steam cycle with the rest of the tray. Clean them open, oil the joint, and check each one closes square before it is packed.
