Introduction

  • Cause: intrauterine position, hereditary, environmental, and nutritional factors have been postulated to be involved in disease etiology.
  • Signs: congenital condition with facial deformity, including deviation of the nasal septum and malalignment of the jaw.
  • Diagnosis: clinical signs consistent with disease, diagnostic imaging, endoscopy.
  • Treatment: mildly affected individuals require no treatment. Severely affected animals should be euthanized on welfare grounds.
  • Prognosis: poor.
