Local glucocorticosteroid (“steroid”) therapy is widely used to treat the inner ears of patients with Menière's disease, idiopathic sudden sensorineural hearing loss and in combination with cochlear implants. Applied steroids have included dexamethasone, methylprednisolone, and triamcinolone. In reality, however, this is often not true and the steroid forms commonly applied are dexamethasone-phosphate, methylprednisolone-hemisuccinate, or triamcinolone-acetonide. In each case, the additional component...

Objective: The incidence of sporadic vestibular schwannoma (VS) has increased significantly over recent decades. The rising incidence of VS has been largely attributed to the increasing use of magnetic resonance imaging (MRI), especially with regard to incidentally diagnosed tumors. However, no study to date has directly investigated this supposed etiology beyond the observation that VS incidence rates have risen in the post-MRI era. Therefore, the primary objective of the current study was to...

Hypothesis: The investigation aimed at measuring the relation between abutment length and Implant Stability Quotient (ISQ) for stability measurements on two types of bone-anchored hearing implant systems. Background: Measuring bone-anchored hearing implant stability using the ISQ has the inherent limitation that the measurement is dependent on the length of the abutment used on the implant. This dependency has not earlier been analyzed in depth. Therefore, ISQ measurements for different abutment...

Introduction: The Eustachian tube plays a crucial role in pressure equalization between the middle ear and ambient pressure for fast and large pressure differences. In patients with chronic Eustachian tube dysfunction, Eustachian tube balloon dilatation is increasingly used as surgical therapy. Subjectively, many patients report an improvement of the symptoms postoperatively. Hence, there is a need to objectively measure this effect. Methods: The objectivity of Eustachian tube balloon dilatation...
