Erectile Ear Dysfunction

Introduction

  • he 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
