call me biased, but you may want to check this young un for an odontogenic tumor

They had a fracture similar to that in one of our female giraffes a few years back, elected to do a hemimandibulectomy, animal is still doing well. It was before my time here, but I believe Chris Hanley down in St Louis could give you more info on that case. The periosteal proliferation is the disturbing part, if this was indeed an acute injury that was noted in a timely fashion. May suggest a more insidious cause.......

As an equally unbiased pathologist, I agree with Mike. That lesion needs to be biopsied.

I monitor discussions quite closely with your list serve and will humbly give my opinion since this problem involves my interest...the oral cavity. There are multiple options to fix fractures within the interdetnal space. These would include: tension-band wiring, oral acrylic splints with/without wire, U-bars, external fixators and bone plating. External fixators and bone plating would not be my first choice due to developing tooth buds (canines, pm). Rostral mandibulectomy would only be an option if this became a non-union or was pathologic. I won't disagree the need to rule out pathologic reason for fracture (odontogenic, other tumor) which can be done with good intraoral RADs. Awesome case. If I can help further let me know. Thanks for letting me give my opinion.

I recommend any diagnosis be confirmed histologically before attempting any further treatment or other. it would be unwise (and embarrassing) to euthanize an animal due to a radiographic diagnosis of neoplasia, and then find that histologically the lesion was an abscess.

I agree with Michael.
But even so, check the hay rack: if it has vertical bars, the anterior part of the head may get stuck between those bars. When the animal suddenly frightens, it can easily fracture the mandible or maxilla. I prefer a net or wire mesh to provide roughage to these animals.

The images appear similar to our 6y male retic, diagnosed by biopsy with an odontogenic mandibular tumor at 3y and stable to date without adverse local invasion or expansion.
