What Is the Eustachian Tube?
Eustachian Tube: A small passage with a big role in ear pressure, comfort, and hearing
“The TUBOMANOMETRY device has significantly improved my ability to diagnose Eustachian tube dysfunction quickly and accurately.”
— Dr. Sarah Thompson
“Using TUBOMANOMETRY has streamlined my practice. It’s user-friendly and provides precise readings that enhance patient care.”
— Dr. Mark Robinson
“I appreciate the support and training provided by TUBOMANOMETRY. It made integrating the device into my workflow seamless.”
— Dr. Emily Carter
When the Eustachian Tube Fails, the Middle Ear Pays the Price
ETD is strongly associated with some of the most common and persistent middle-ear problems across both children and adults.
Up to 70% — Chronic Otitis Media & Cholesteatoma
Eustachian tube dysfunction has been reported in up to 70% of patients undergoing tympanoplasty for chronic otitis media or cholesteatoma, showing how closely ET function is tied to chronic middle-ear disease.
Up to 40% — Pediatric Middle-Ear Disease
Up to 40% of children may experience Eustachian tube dysfunction. In children, ETD is strongly associated with otitis media with effusion, tympanic membrane retraction, and other chronic middle-ear problems.
4.6% — A Common Adult Problem
ETD affects an estimated 4.6% of U.S. adults — about 11 million people. Persistent dysfunction can lead to negative middle-ear pressure, fluid retention, and eardrum retraction, contributing to chronic ear disease.
What We Offer
Discover the innovative solutions for Eustachian tube diagnosis and treatment
Objective Diagnosis — TMM
TMM objectively measures how the Eustachian tube opens during swallowing, providing clear pressure curves and quantitative data to support accurate functional assessment and clinical decisions.
Non-Invasive Treatment — Otuba
Otuba combines controlled Eustachian tube insufflation with nebulized medication delivery to improve ventilation, relieve local mucosal swelling, and support functional recovery — without surgery.
From Diagnosis to Treatment
Together, TMM and Otuba create a practical diagnosis-and-treatment pathway: identify Eustachian tube dysfunction, choose the right treatment approach, and evaluate functional improvement over time.
Real-Time Eustachian Tube Function Analysis
Dynamic pressure-curve measurement for objective evaluation of Eustachian tube opening
