The auditory tube connects the tympanic cavity with nasopharynx. Due to its structure and position, it is difficult to demonstrate the auditory tube in its whole length and to study its topography on anatomical specimens. The purpose of our study was to present the sectional anatomy of the auditory tube in order to facilitate understanding of its structure and topography. We utilized serial sections of the cadaveric head in four planes: transverse, oblique, frontal and sagittal. The osseous part of the auditory tube was demonstrated on transverse sections and most of the cartilaginous part on oblique sections of the head and neck. The tensor veli palati muscle was found to consist of bilaminar muscle sheet: the outer part originating from the skull base and the inner part originating from the lateral cartilaginous lamina and membranous part of the tube. Topographic relations seen on four section planes were described in detail. The structure, course, and topography of auditory tube are well demonstrated on sectional images. Detailed knowledge of the sectional anatomy of the auditory tube is important for the interpretation of corresponding computerized tomographic and magnetic resonance images, and in understanding the disorders and diseases affecting the middle ear and mastoid.

AbstractThe value of tubal inflation as a diagnostic procedure for Eustachian tube patency and function is controversial. In an attempt to assess the diagnostic value of air douche in atelectatic ears, 49 such ears of 40 patients were politzerized. The procedure was successful in 45 ears. However, of the four unsuccessful cases, two of the patients were able to autoinflate their ears. These results show that air douches pass regularly through the Eustachian tube into the tympanic cavity even in atelectatic ears, which by definition suffer from aeration deficiency, which is often considered to be secondary to ‘Eustachian tube obstruction’, or alternatively ‘Eustachian tube dysfunction’. Thus, the ability to force air through the Eustachian tube by politzerization is of no diagnostic value as an indicator of normal or abnormal tubal patency or functioning in atelectatic ears and most probably in allied conditions.

Endotracheal Anesthesia

Treatment of otitis media with effusion (OME) in most cases requires topical application of medications, which are designed to stop the inflammatory process and act on exudate in the middle ear cavity. One of the most common treatments for OME is catheterization of the auditory tube using a Guillot catheter, which is not always effective. This work presents the second stage of the study on the introduction of drugs into the middle ear using an original ear catheter. The study included patients with OME (N = 14, the duration of the disease from 2 to 3 months). The patients underwent surgical treatment: bypass of the eardrum, septoplasty, turbinoplasty under endotracheal anesthesia. An intraoperative experiment was conducted to evaluate the effectiveness of catheterization of the auditory tube with an original catheter, a tinted solution and Miramistin solution. In all 14 cases, the eardrum of the affected ear during catheterization made oscillatory movements, synchronously with the reciprocating movements of the syringe plunger. In 2 cases (14.3%), we did not visualize the tinted solution behind the eardrum. The full filling of the tympanic cavity with tinted saline was 4 patients (28.6%), while the average volume of the injected solution (V) was 4.09 ml, and in 8 ears (57.1%) the tympanic cavity was partially filled with the contrast solution (V = 7.0 ml). In case of transtubar injection of Miramistin solution in the tympanic cavity in all cases (14 ears), the antiseptic solution enters the external auditory canal after myringotomy. By correlating the average volume of the tympanic cavity with the volume of the injected drug necessary for the initial filling of the tympanic cavity, the minimum loss of the liquid form of the drug was 1: 2.

Tube Dysfunction

Introduction: Eustachian tube dysfunction (ETD) and middle ear barotrauma (MEB) are the most common adverse effects of hyperbaric oxygen (HBO2) treatments. Patients practice equalization maneuvers to prevent ETD and MEB prior to hyperbaric exposure. Some patients are still unable to equalize middle ear pressure. This ETD results in undesirable consequences, including barotrauma, treatment with medications or surgical myringotomy with tube placement and interruption of HBO2. When additional medications and myringotomy are employed, they are associated with additional complications. Methods: A device known as the Ear Popper® has been reported to reduce complications from serous otitis media and reduce the need for surgical interventions (myringotomy). Patients unable to equalize middle ear pressure during initial compression in the hyperbaric chamber were allowed to use the device for rescue. All hyperbaric treatments were compressed using a United States Navy TT9, or a 45-fsw hyperbaric treatment schedule. Patients with persistent ETD and the inability to equalize middle ear pressure were given the Ear Popper upon consideration of terminating their treatment. Results: The Ear Popper allowed all patients to successfully equalize middle ear pressure and complete their treatments. Conclusion: This study substantiates the use of this device to assist in allowing pressurization of the middle ear space in patients otherwise unable to achieve equalization of middle ear pressure during HBO2 treatment in a multiplace chamber.

Causes Of Failure

AbstractForty cases of failed combined approach tympanoplasty were analysed. The commonest cause of failure was adhesions between the facial ridge and the tympanic membrane, causing segmental attico-mastoid malaeration in 51.3 per cent of cases followed-up continually. Other causes were, large dermoids, incomplete removal of squamous epithelium, and eustachian tube obstruction. Eustachian tube dysfunction did not appear to be a major cause of failure.

Relationships between middle ear pressure and non-infection-related cochleovestibular dysfunction have been suggested by several authors. According to some data, vertiginous attacks can be prevented by the insertion of a ventilation tube in patients suffering from Meniere's syndrome. The aim of our study was to investigate if the incidence of eustachian tube malfunction and pathologic middle ear pressure is frequent, and if routine implantation of ventilation tubes is reasonable in ears with dysfunctions of the labyrinth, including clinical Meniere's syndrome. So, we determined in our pressure chamber all active and passive parameters of eustachian tube function in 40 patients suffering from Meniere's syndrome, sudden sensory hearing impairment (SSHI), or vestibular neuronitis. Our results disclosed no nonrandom incidence of impaired tubal function among our patients compared to healthy control subjects. Pressure equalization was sufficient in most patients suffering from clinical Meniere's syndrome, and only one patient with vestibular neuronitis presented with a patulous tube. Our results show that impairment of vestibular or cochlear function is not regularly accompanied by eustachian tube dysfunction. Furthermore, no patient reported symptoms while pressure variation was performed. We conclude that variation of middle ear pressure does not usually play a role in the genesis of Meniere's syndrome, vestibular neuronitis, or SSHI. Thus, from our data, we cannot recommend routine implantation of tympanic ventilation tubes in patients suffering from Meniere's syndrome, vestibular neuronitis, or sudden hearing loss.

AbstractObjectiveTo assess the effect of topical betahistine on Eustachian tube function in subjectively abnormal subjects in a hyperbaric chamber.MethodActive and passive Eustachian tube function was examined using tympanometry in a pressure chamber.ResultsActive Eustachian tube function was tested against the negative middle ear pressure induced by increasing the chamber pressure to +3 kPa. One voluntary swallow decreased middle-ear pressure by a mean of 1.36 kPa. Passive Eustachian tube function was tested by measuring spontaneous Eustachian tube openings as the chamber pressure dropped from +10 kPa to ambient. Four distinct patterns of Eustachian tube behaviour were seen, three of which indicated Eustachian tube dysfunction. Betahistine had no positive effect on Eustachian tube opening, although previous animal studies had suggested a beneficial effect.ConclusionTopical betahistine had no effect on Eustachian tube function. Combining a hyperbaric chamber with tympanometry proved ideal for evaluating Eustachian tube function.
