What is Eustachian Tube Dysfunction?
Eustachian Tube Dysfunction is a common problem affecting the structures of the inner ear (Eustachian tubes) of both children and adults. Common secondary conditions (a.k.a. symptoms) of Eustachian Tube Dysfunction include earaches, dizziness, fullness in the ear, tinnitus (ringing in the ear), and more. Conditions such as vertigo, Meniere’s, and endolymphatic hydrops include signs and symptoms of ETD.
There are various causes of Eustachian Tube Dysfunction, some commonly understood and others less so. Understanding the cause of Eustachian Tube Dysfunction helps to shed light on proper treatments and potential triggers. The causes can be due to inflammation in the tissues surrounding the inner ear, pressure changes (such as flying, high altitude hiking, riding in an elevator), or from structural obstructions to the structures of the inner ear.
Inflammation of the Eustachian Tubes is commonly referred to as an “ear infection” and is unfortunately common (but not normal) among newborns and infants. In adulthood, the Eustachian Tubes are angulated downward to drain into the back of the nose and throat. In infancy and childhood, the tubes are angulated horizontally and may not drain properly if tissue inflammation or obstruction is present. This can lead to pain, pressure, discharge, or chronic ear infections in pediatric patients. For Eustachian Tube Dysfunction related to bacterial sinus infections, antibiotics are often needed to fully resolve the condition.
Causes: Structural Nerve Irritation
In the absence of a sinus infection, Eustachian Tube inflammation can be caused by several other factors. One of the most commonly overlooked causes of Eustachian Tube Dysfunction lies in the neurological supply to the muscles that constrict and surround the Eustachian Tubes. The nervous system acts as the electrical communication system of the body. A network of nerve fibers connects the brain to various structures in the body so that the body can adapt to changes in its environment (both internal and external). These individual “circuits” are subject to being overloaded or obstructed in the same way that circuits within your home can become overloaded. When this occurs the end organ (tissue or structure at the end of the circuit) is compromised in its function.
The nerve supply to the Eustachian Tubes is provided by a branch of the Vagus nerve. This nerve starts in the lower part of the brain (called the brainstem or medulla oblongata) and travels through the base of the skull and upper neck giving off branches to various structures including the Eustachian Tubes.
Mechanical Irritation of this nerve circuit has been documented in cases of Atlas Displacement Complex, also known as Upper Cervical Subluxation. An abnormal structural position of the head and neck produces biomechanical dysfunction and local irritation in the area of the brainstem and upper spinal cord. If the “circuit” supply the Eustachian Tube or its supporting musculature is affected, Eustachian Tube Dysfunction is a common side effect.
There are a number of ways to distinguish between a bacterial cause or a structural cause of Eustachian Tube Dysfunction which helps to guide appropriate treatment.
