He suffered from a chronic ear infection and was treated with antibiotics for several months, but the results were not satisfactory. “
Total ear canal ablation is the complete removal of the ear canal, usually performed in dogs. But the OSU vet.Katy TownsendDoctors have found no record of this type of surgery being performed on pigs, whose external ear canals are primarily located in the bony columns, making them difficult to access.
Although pig ears are very different from dog ears, the structure of the former is similar to that of human ears. SOcleansendCall his doctor for advice. Portland Ear SurgeonsTimothy HullarDoctors performed the operation on him five years ago to treat a condition called otosclerosis, in which the bones of the inner ear fuse together and cause deafness.

TownsendAndBlanketsCooperation came quickly. Meanwhile, from Oregon State University Vet.Susanne Stieger VanegasThe doctorate helped them with diagnostic imaging and printing, according toEllaAccepted to Oregon State UniversityCTscanned and they got a3DSkull print. This helps the team think through and plan the next steps in the surgical procedure.
Blankets“I read ear scans at least five times a day,” he said, who still works at the Portland Veterans Affairs Health System, “but the pigCTNot common. The anatomy makes sense to me, a pig’s outer ear is completely different than a human’s, but there are some similarities between the inner ear and the middle ear. “
EllaAn ear infection was causing him a lot of pain, and neurological issues were causing him to lose his balance and find himself unable to walk at any time.
△Previously, surgeons used3DA surgical plan was developed by printing the kidney model and the operation was successfully performed. The model is so realistic that it not only contains the tumor to be removed, but also bleeds when cut.
The surgical team suddenly proposedA、B、C、DFour treatment options so that they could be adjusted if difficulties arose during the operation, but the operation went so well that they only resulted inAset of plans.
