This condition results in the inability of the ear flap to assume an erect position – the ear will not stand up and just flops over
Trauma or a congenital defect of the cartilage or muscles that pull the ear up may be causes of this condition
Taping the ear up frequently does not result in resolution of clinical signs in severe cases
Surgery has a good outcome
Introduction
the ear is made of a series of cartilages
the position of the ear flap is largely controlled by muscles that attach onto the cartilages of the ear
trauma (pulling of the ear) when a dog is a pup (or even when it is mature) may cause disruption of the muscles of the ear and cause the ear flap to flop over
Signalment
the problem is only noted in dogs that normally have erect ears
it can be seen in young dogs
Signs
inability of the ear flap to assume an erect position
Treatment
the scutiform cartilage is examined at the time of surgery for damage
if the scutiform cartilage is torn from the pinnal cartilage it is reattached with nonabsorbable sutures
care is taken during the surgery to prevent damage to the muscles that control ear movement
a graft (collagen called laminated BIOSIS) is sutured to the cartilage of the ear flap (typically the scutiform) and to the occipital crest (bony projection of the skull)
Prognosis
good prognosis with surgery
the ear will permanently assume an erect position and likely will not lay flat even if the dog tries to do this
the ear typically can still rotate forward and backward, thus hearing ability is improved with surgery
Complications
infection
seroma formation
recurrence of erectile ear dysfunction necessitating another surgery
Testimonial
Hank is doing great and back to his old self. The ear looks great and the hair is coming back in. I’ll be able to send you a good “after” photo in a month or so. It looks to me like he has full mobility. He cocks it around, lays it back, etc. pretty much everything the left ear does, the right does.
