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:
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.
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.
Remember, always consult a veterinarian for personalized advice tailored to your pet’s specific needs.
