What Is a Hofer Osteotomy in Orthognathic Surgery?

That wording matters. It anchors the term to a specific lower-jaw region, rather than to every possible operation on the mandible. It does not automatically tell you the exact cut design, the direction of movement, the amount of movement, or whether other jaw procedures are planned.

Why the “alveolar process” detail matters

The key anatomical clue is the phrase alveolar process. The Hofer-related sources describe the procedure in relation to the alveolar process of the mandible, or lower jaw .

That is narrower than the general term “mandibular osteotomy.” A broader orthognathic-surgery reference notes that mandibular osteotomies may be performed in several regions, including the ramus, body, chin, dento-alveolar region, and inferior border . So if a note uses the Hofer name, it suggests a more specific dento-alveolar or alveolar lower-jaw context than “mandibular osteotomy” alone.

How it fits into orthognathic surgery

Orthognathic surgery is the broader category of corrective jaw surgery. Boston Children’s Hospital lists possible reasons for jaw surgery including bite problems such as underbite, large overbite, crossbite, or open bite; facial asymmetry; difficulty with lip closure; jaw-joint stability; growth abnormalities associated with cleft conditions; and obstructive sleep apnea .

A Hofer osteotomy reference is much narrower than that full field. It is best treated as a procedure term or anatomical reference—not as a diagnosis, an indication for surgery, or a complete treatment plan .

Hofer osteotomy vs. related terms

What the term does not tell you

Even when “Hofer osteotomy” appears in a consultation note or surgical plan, the phrase leaves important details unanswered. It does not specify:

• the exact osteotomy design;
• the direction or amount of bone movement;
• whether movement is limited to the alveolar or dento-alveolar segment;
• whether other mandibular or maxillary procedures are planned;
• how orthodontic treatment fits before or after surgery.

Those details need to come from the surgeon’s explanation and the formal treatment plan.

Questions to ask your surgeon

If you see “Hofer osteotomy” in your records, focus the conversation on anatomy, purpose, and alternatives. Useful questions include:

• Which exact part of my mandible is being cut and repositioned?
• Are you using “Hofer” as the formal procedure name, as an eponym, or as shorthand for a related technique?
• Is the movement limited to the alveolar or dento-alveolar segment?
• Is this part of a larger orthognathic correction?
• What orthodontic steps are expected before or after surgery?
• What alternatives were considered, and why is this approach preferred for my case?

Bottom line

“Hofer osteotomy” should be interpreted precisely but cautiously. The clearest documented meaning is Hofer’s 1942 osteotomy of the alveolar process of the lower jaw, with later literature describing a sagittal sliding modification of that procedure . It is not a blanket term for all mandibular osteotomies or all orthognathic surgery. The exact meaning in your case depends on the wording of the surgical plan and your surgeon’s explanation of which jaw segment is being moved.
