Article Synopsis
- - The study aimed to determine the prevalence of dilatory eustachian tube dysfunction (ETD) in adults undergoing surgery for chronic middle ear disease, by evaluating patients with specific ear conditions while excluding those with unrelated issues.
- - Researchers assessed ETD using the Valsalva maneuver and the eustachian tube score (ETS), defining dilatory ETD based on negative Valsalva results and low ETS scores.
- - Results showed that 82% of the 482 patients had no detectable dilatory ETD according to standard clinical methods, suggesting a need to reconsider common assumptions about this condition's prevalence in such patients.
Hyperbaric oxygenation (HBO) represents the controlled exposure to positive pressure with simultaneous inhalation of pure oxygen. It is considered to be an effective treatment option for diseases with restricted blood flow as oxygen not only binds chemically to hemoglobin but also physically dissolves in blood plasma. With the help of a hyperbaric chamber the ambient pressure of a patient can be modified and the physiological characteristics in positive pressure can be medically used.

For temporal bone surgery, shown here by means of mastoidectomy, there are other training models besides cadaver specimens, such as artificial temporal bones or computer-based simulators.
Objectives: A structured training concept was created which integrates different training methods of mastoidectomy with regard to effectiveness and current learning theory in education.
