Otogenic brain abscess and concomitant acute COVID 19 infection - case report and review of the literature.

Background: COVID-19 has attracted global attention primarily because of the severe acute respiratory symptoms associated with it. However, nearly one third of the patients also present with neurologic symptoms. This report describes a case of a previously healthy woman with acute COVID-19 infection, who developed acute facial nerve palsy and rapid progression to coma due to otogenic brain abscess.

Exercises to improve directional sound recognition by visually impaired users heading to the workplace.

Moving is an integral part of everyday life and applies to accessing the workplace, attending a health centre or meeting friends. Determination of the source of sound may be important when a visually impaired person is moving around. This allows to navigate, but also provides important information about potential danger.

High hydrostatic pressure treatment for advanced tissue grafts in reconstructive head and neck surgery.

The increasing importance of regenerative medicine has resulted in a growing need for advanced tissue replacement materials in head and neck surgery. Allo- and xenogenic graft processing is often time-consuming and can deteriorate the extracellular matrix (ECM). High hydrostatic pressure (HHP)-treatment could allow specific devitalization while retaining the essential properties of the ECM.

The Predictive Value of Preoperative Measurements of Cochlear Nerve Diameters From MRT and Postoperative Speech Perception in Adult Patients With Cochlear Implant.

Objective: The current study aims to investigate whether objective measurements of the cochlear nerve (CN), derived from preoperative MRI images, correlate with postoperative speech perception in CI patients.

Study Design: Retrospective cohort study.

Setting: University Medical Center, tertiary academic referral center.
