Methods: Retrospective analysis of preoperative CT scans was performed at a tertiary center.

Revisions after prior stapes surgery: aspects on indication, intraoperative findings and surgical strategies.

Objective: Primary stapes surgery is considered a challenging intervention in ear surgery. Despite an risk of deafness in 0.5-1 percent, this procedure has still a good benefit-risk ratio due to the improvement in hearing and quality of life that is usually achieved.

Middle ear malformations (MEMs) represent a diverse group of congenital anomalies with significant implications for auditory function. These malformations, which occur in approximately 0.5 to 3% of conductive hearing loss cases, can arise from various genetic and environmental factors.

Tenfold Increase: Acute Pediatric Mastoiditis Before, During, and After COVID-19 Restrictions.

Introduction: Acute mastoiditis (AM) is a relatively rare complication arising from acute otitis media, a common condition among children. The COVID-19 pandemic has significantly impacted AM cases. We noted a surge in pediatric AM cases in Germany after COVID-19 restrictions were lifted in 2022.

Comparison of Two Measurement Paradigms to Determine Electrically Evoked Cochlear Nerve Responses and Their Correlation to Cochlear Nerve Cross-section in Infants and Young Children With Cochlear Implant.

Introduction: Electrically evoked compound action potentials (ECAPs) are used for intra-/postoperative monitoring with intracochlear stimulation of cochlear implants. ECAPs are recorded in MED-EL (Innsbruck, Austria) implants using auditory response telemetry (ART), which has been further developed with automatic threshold determination as AutoART. The success of an ECAP measurement also depends on the number of available spiral ganglion cells and the bipolar neurons of the cochlear nerve (CN).

Comparison of speech perception in bimodal cochlear implant patients with respect to the cochlear coverage.

Outcome of Auricular Reconstruction with Porous Polyethylene Frameworks: Our 10 Years of Experience with 113 Children and Adults.

This study evaluates the surgical outcome and patient benefit after auricular reconstruction with porous polyethylene frameworks and temporoparietal fascia flaps in both children and adults. A total of 161 patients who had undergone auricular reconstruction between 2003 and 2014 by doctors in our department were asked to answer both a validated health-related quality-of-life questionnaire (Glasgow Benefit Inventory or Glasgow Children's Benefit Inventory) and a questionnaire reporting satisfaction, complaints, and complications with the reconstructed pinna. Furthermore, postoperative surgical complications were recorded.

Variation of the cochlear anatomy and cochlea duct length: analysis with a new tablet-based software.

Purpose: In cochlear implantation, thorough preoperative planning together with measurement of the cochlear duct length (CDL) assists in choosing the correct electrode length. For measuring the CDL, different techniques have been introduced in the past century along with the then available technology. A tablet-based software offers an easy and intuitive way to visualize and analyze the anatomy of the temporal bone, its proportions and measure the CDL.

Comparison of ABR and ASSR using NB-chirp-stimuli in children with severe and profound hearing loss.

Introduction: Objective techniques for hearing threshold estimation in infants and children with profound or severe hearing loss play a key role in pediatric audiology to prevent speech acquisition disorders by choosing the adequate therapy. Auditory brainstem responses and auditory steady-state responses are available for frequency-dependent hearing threshold estimations and both techniques show strong correlations. However, various systems and stimuli are available, which is one reason why comparison is challenging, and, so far, no single "gold standard" could be established for hearing threshold estimation in children suffering from profound or severe hearing loss.

Extended Applications for Cochlear Implantation.

The indications for cochlear implantation (CI) have expanded over the last few years. There is evidence that some adult patients with pre- or perilingual onset of deafness may gain from implantation. Similarly, CI in patients with single-sided deafness may offer significant benefits in terms of quality of life and social as well as academic development.
