What is Ventral Bulla Osteotomy (VBO)?

Ventral Bulla Osteotomy (VBO) is a specialized surgical procedure performed in dogs and cats to address middle ear diseases. It involves accessing the middle ear (bulla) through a small incision in the neck. Here’s what you need to know:

Indications:

  • Chronic Otitis: When ear infections persist despite medical treatment.
  • Inflammatory Polyps: Removal of polyps within the bony canal of the ear.
  • Tumors: Excision of benign or malignant growths affecting the middle ear.

Procedure:

  1. Surgical Approach:

    • The surgeon makes an incision along the underside of the neck.
    • The osseous bulla (middle ear) is exposed.
    • The bulla is entered using specialized instruments (intramedullary pin and rongeurs or a pneumatic drill).
    • The bony septum separating the ventromedial and dorsolateral compartments of the middle ear is removed.
    • The epithelial lining of the bulla is curetted.
    • If indicated, inflammatory polyps or tumors are excised.
  2. Post-Operative Care:

    • Pain Management: Ensuring comfort during recovery.
    • Wound Care: Regular monitoring and cleaning.

Benefits:

  • Disease Control: Removal of infected tissue or abnormal growths.
  • Improved Quality of Life: Relief from chronic ear issues.
  • Preservation of Ear Flap: The external ear flap (pinna) remains unchanged.
