Etiology

  • DISCUSSION It is important to make an etiological diagnosis for children with sensorineural hearing loss because procedures can differ if it is a case of malformation.[arquivosdeorl.org.br]
  • Etiology The precise etiology of the failure of EAC canalization is not known. Associations have been postulated between EACA and low birth weight, intrauterine trauma, toxins, or infection.[emedicine.medscape.com]
  • While there may be subtle distinctions between these conditions, the presumed etiology is inflammation. In this condition the vertigo comes on quickly and patients often have severe nausea and can't walk.[dartmouth.edu]
  • .  Suggested etiologies include-  vascular insufficiency because of its relatively poor blood supply  The micro angiopathy of diabetes  Small arterial emboli have been suggested.  Repeated local trauma is a popular theory, for example ear bud abuse[slideshare.net]
  • The etiology of the disease is still poorly understood, but it is associated with both genetic and environmental factors. In early stages, the normal bone is replaced with spongy, irregular bone.[appliedradiology.com]
