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.
