“…We recently described Valsalva CT as a way to identify distal obstruction; in the great majority of the normal population, the distal one-third of the Eustachian tube can be visualized and the patency of that segment of the Eustachian tube can be assured. 8 In our study population of patients undergoing surgery for chronic ear disease, only two ears had a distal obstruction, which is similar to the frequency expected in the general population.…”

“…Endoscopic ear surgery with rigid angled scopes allows for high‐resolution evaluation of the protympanic segment of the tube . Valsalva computed tomography (CT) has been recently reported by our group as a method for visualizing the lumen of the distal one‐third of the Eustachian tube . We have utilized both modalities to evaluate any identifiable anatomic obstruction in the Eustachian tube in patients undergoing ear surgery for chronic disease in our practice.…”

“…Preoperative computed tomography (CT) was used for calibration and visualization of the cartilaginous portion of ET [13]. High-resolution paranasal CT scans were conducted using a GMS Revolution CT scanner (GE Healthcare, Milwaukee, WI, USA) with the patients in supine position, with and without Valsalva maneuver.…”

Objectives. Balloon Eustachian tuboplasty (BET) is a novel treatment method for Eustachian tube dilatory dysfunction (ETD). However, surgeons cannot identify the insertion depth of the catheter during BET, resulting in potential risks such as internal carotid artery (ICA) injury. Therefore, we developed an image-guided navigation balloon catheter to identify the insertion depth of the catheter and to establish awareness of the proximity of the ICA. This study aimed to evaluate the technical feasibility of this image-guided navigation balloon catheter system in patients with ETD.Methods. Twenty-nine patients (38 ears; nine bilateral; 21 right ears, and 17 left ears) diagnosed with ETD were assessed. All patients who showed no improvement despite medical therapy with topical steroids, anti-reflux medication, and the Valsalva maneuver for a minimum of 6 weeks received image-guided navigation-assisted BET. The 7-item Eustachian Tube Dysfunction Questionnaire (ETDQ-7) score and Valsalva maneuver were used to evaluate patients’ symptoms preoperatively and at the postoperative follow-up.Results. Image-guided navigation-assisted BET was safely performed in all patients. The mean total ETDQ-7 score was 25.4±7.1 preoperatively, 17.5±6.2 at 1 month, and 15.2±7.0 at 6 months (<i>P</i><0.001). In total, a Valsalva maneuver was possible for 28 of 38 ears (73.7%) at the time of the patient’s final visit at 6 months post-procedure.Conclusion. Image-guided navigation balloon catheters are a potentially valuable tool in patients with ETD. Their use is also technically feasible and safe when performing BET to treat ETD.

“…Tóth et al [5] showed that the main structure of the protympanum develops from the petrous part of the temporal bone while the tympanic part forms the posterior border of the protympanum laterally. It is also the location of the narrowest portion of the Eustachian tube, the isthmus [6, 7]. …”

Eustachian tube dysfunction is believed to be an important factor to cholesteatoma development and recurrence of disease after surgical treatment. Although many studies have described prognostic factors, evaluation methods, or surgical techniques for Eustachian tube dysfunction, they relied on the soft tissues of its structure; little is known about its bony structure – the protympanum – which connects the Eustachian tube to the tympanic cavity, and can also be affected by several inflammatory conditions, both from the middle ear or from the nasopharynx. We studied temporal bones from patients with cholesteatoma, chronic otitis media (with and without retraction pockets), purulent otitis media, and non-diseased ears, looking for differences between the volume of the protympanum, the diameter of the Eustachian tube isthmus, and the distance between the anterior tympanic annulus and the promontory. Light microscopy and 3-D reconstruction software were used for the measurements. We observed a decrease of volume in the lumen of the four middle ear diseased ears compared to the control group. We observed a significant decrease in the volume of the protympanic space in the cholesteatoma group compared to the chronic otitis media group. We also observed a decrease in the bony space (protympanum space) in cholesteatoma, chronic otitis media with retraction pockets, and purulent otitis media compared to the control group. We found a correlation in middle ear diseases and a decrease in the middle ear space. Our findings may suggest that a smaller bony volume in the protympanic area may trigger middle ear dysventilation problems.
