What is Total Ear Canal Ablation and Bulla Osteotomy (TECA-BO)?

TECA-BO is an abbreviation for Total Ear Canal Ablation and Bulla Osteotomy. This surgery involves the complete removal of the ear canal and the tympanic bulla (middle ear), leaving only the pinna (ear flap) remaining. It is primarily recommended in cases of chronic, end-stage otitis (ear infections) where medical treatment is no longer effective. Let’s explore further:

Indications:

• Chronic Otitis: When ear infections persist despite medical management.
• Bacterial Resistance: In cases where bacterial infections are resistant to antibiotics.
• Severe Scarring and Narrowing: Chronic inflammation leads to significant scarring and narrowing of the ear canal, rendering ear cleaning ineffective.
• Neoplastic Growth: Removal of cancerous masses confined to the ear canal.

Procedure:

1. Pre-Operative Assessment:

   • Physical examination evaluates the extent of ear abnormalities.
   • Pre-anesthetic blood tests assess internal organ function.
   • Imaging (CT scan or MRI) provides effective visualization of the ear canals and bullae.

2. Surgery:

   • Under general anesthesia, the surgeon makes a skin incision surrounding the ear.
   • The ear canal is removed as one intact cylinder, including the eardrum and middle ear bones.
   • The tympanic bulla is exposed, and infected material is removed for bacterial culture.

Post-Operative Care:

• Pain Management: Ensuring comfort during recovery.
• Wound Care: Regular cleaning and monitoring.
• Quality of Life Improvement: Reduced pain and inflammation.

Benefits:

• Disease Control: Removal of infected tissue.
• Improved Quality of Life: Relief from chronic pain.
• Cosmetic Outcome: Preservation of the pinna.
