Hi,
Torticollis....aka as wry neck or head tilt....is almost always caused by a bacterial infection in the middle and/or inner ear. About the only other thing that definitely causes tilt is obvious head trauma. Contrary to popular belief, E Cuniculi does notprimarily cause head tilt (as has been the general belief for years). EC compromises the immune system and that can allow bacterial infections to invade. Ear infections are much more serious in rabbits than in dogs or cats. Most vets treat ear infections far too conservatively. Ear infections have produced the highest body temps of any infection I have even seen....and I have seen a lot of infections. Sometimes the body temp will reach near 106F and that is dangerous. Keep in mind that the ear infection may be a stand alone infection....or could be secondary to a dental problem as well as EC. Around here, I fire all the big guns against ear infections. The treatment should also include lots of support in the form of pain management, hydration and nutritional support.
And in hoping it's an easy fix....we have had ear mites cause slight tilting. It is also much easier to treat an ear infection when it's caught early....and that seems to be the case here. Keep us posted.
