Balloon Dilation of the Eustachian Tube

Dennis Poe, MD

• Eustachian tube dysfunction
• Recurrent serous otitis media

• Balloon is passed under endoscopic visualization
• The catheter should advance easily without resistance
• Balloon is inflated to 12 atmospheres for 2 minutes, then deflated and withdrawn

Keep in Mind:
• The purpose is to dilate the cartilaginous distal end of the Eustachian tube, not the more proximal bony segment
• If resistance to passage of the balloon occurs, it should be partially withdrawn prior to inflation to avoid injury to the adjacent carotid canal
