  • Pre-existing chronic infectious diseases, liver cirrhosis, and autoimmune conditions were excluded. (bvsalud.org)
  • The proper broad-spectrum antimicrobial therapy is usually administered as part of the treatment for the infectious causes of the disease. (healthncare.info)

  • Seven bones conjoin to form the orbital structure, as shown in the image below. (medscape.com)
  • The orbital plate of the maxilla joins the orbital plate of the zygoma and the orbital plate of the palatine bones to form the floor. (medscape.com)
  • Surgery - When a surgical procedure is done, it repairs the tissue prolapse and the orbital wall, and in severe cases, sometimes, an implant is placed to create a new orbital wall. (tnoculoplastics.com)
  • Autoimmune disease caused by an antibody that acts as an agonist on the thryotropin receptor. (standardofcare.com)
