Does the ChOLE classification relate to the duration of surgery?

Introduction: Cholesteatoma, a challenging entity in otologic surgery, necessitates a standardized classification system for effective communication among healthcare providers and consistent reporting of surgical outcomes. The ChOLE Classification System, introduced by Linder et al., stages cholesteatoma based on extension (Ch), ossicular chain status (O), life-threatening complications (L), and Eustachian tube function and mastoid pneumatization (E).

Cochlear measurement in computed tomography and magnetic resonance imaging data sets by the Otoplan measurement tool: a retrospective comparative study.

Background: Using Otoplan software, it is possible to measure the cochlea before cochlear implant surgery. Until now, computed tomography (CT) of the cochlea has been necessary for this purpose. The aim of this study was to find out whether measuring the cochlea with magnetic resonance imaging (MRI) using Otoplan is possible with the same accuracy.

[Vestibular Schwannoma: Factors in Therapy Decision-Making].

The treatment of vestibular schwannomas (VS) has always posed a challenge for physicians. Three essential treatment principles are available: wait-and-scan, surgery, and stereotactic radiotherapy. In addition to the type of treatment, decisions must be made regarding the optimal timing of therapy, the combination of different treatment modalities, the potential surgical approach, and the type and intensity of radiation.

[Predatory journals in otorhinolaryngology].

Background: Pseudo-scientific predatory journals have been making a commercially lucrative business with scientific manuscripts for many years misusing the "open access" model by offering a fast and uncomplicated publication of scientific manuscripts in return for publication fees. The question arises as to whether the specialty field of otorhinolaryngology has already been infiltrated by this bad practice.

Material And Methods: A pseudo-scientific fake manuscript was sent to 20 journals in which the journal title indicated an otorhinolaryngological content.

Initial clinical experience with N-hexyl cyanoacrylate for neuroendovascular embolization.

Objective: To report our initial clinical experience with N-hexyl cyanoacrylate (NHCA), a novel liquid agent for neurovascular embolization.

Methods: Four paragangliomas were treated with percutaneous embolization using NHCA as the sole embolic material. In one dural arteriovenous fistula (dAVF), NHCA was used in combination with other embolic materials.

Effective high-throughput RT-qPCR screening for SARS-CoV-2 infections in children.

Systematic SARS-CoV-2 testing is a valuable tool for infection control and surveillance. However, broad application of high sensitive RT-qPCR testing in children is often hampered due to unpleasant sample collection, limited RT-qPCR capacities and high costs. Here, we developed a high-throughput approach ('Lolli-Method') for SARS-CoV-2 detection in children, combining non-invasive sample collection with an RT-qPCR-pool testing strategy.

The DERIVO 2heal embolisation device: A technical report using single antiplatelet therapy for intracranial pseudoaneurysm treatment.

The novel DERIVO 2heal Embolisation Device (Acandis, Pforzheim, Germany) is a flexible, fully radiopaque flow-diverter with a fibrin-based nano-coating, which is supposed to make the device inert to the coagulation cascade. We report a case of pseudoaneurysm treatment with this device under single anti-platelet therapy (SAPT). A female patient underwent endoscopic surgery for chronic rhinosinusitis.

Impact of COVID-19-Mediated Olfactory Loss on Quality of Life.

Introduction: COVID-19 can be associated with a variety of longer-lasting impairments that can have a significant impact on patients' quality of life (QoL). While this is well described in the literature for limitations in lung capacity or permanent headaches, there is little research on the impact of olfactory dysfunction in the context of COVID-19 on patients' QoL.

Methods: In 65 patients with a history of COVID-19, the present olfactory ability was assessed using the Sniffin' Sticks test.

[Updated S2k AWMF guideline on obstructive sialadenitis].

The update of this guideline was an important step to define standards for the use of sialendoscopy and other emerging minimally invasive techniques for the therapy of sialolithiasis and other obstructive salivary gland diseases. The current actualization was necessary to adapt the diagnostic and therapeutic algorithms to the current scientific knowledge. In this article they are presented in a shortened version with a focus on conservative therapeutic measures which are especially relevant for daily practice.

Patients with COVID-19-associated olfactory impairment also show impaired trigeminal function.

Objective: Next to olfactory function, the nose can also perceive chemestetic sensations mediated by the trigeminal nerve. While olfactory dysfunction as a symptom of COVID-19 is well described, there has been little research on the limitation of other nasal sensory inputs due to SARS-CoV-2 infection. The aim of this study was to determine possible limitations of nasal chemesthesis after COVID-19 infection by a psychophysiological diagnostic tool.

Taste-strip gustometry in cochlear implanted patients.

Objective: Investigation of the gustatory function in a large cohort of cochlear implanted patients using lateralized taste-strip tests.

Aims/objectives: The aim of this study was to investigate how many patients with olfactory function impairment, which was detected in a validated olfactory test 3 months after COVID-19 disease, showed improvement in olfactory function after 6 months.

[Is Flying or Diving risky after cochlear implantation? Examination in a pressure chamber].

Objective:  Complications after cochlear implantation are relatively rare but patients are asked to follow certain behavioral rules. Until now there is no evidence if pressure changes that occur during flying and diving are safe for patients after cochlear implantation. For example, no recommendation exists for SCUBA- diving activities.

Evaluation of a New Material From an Allogenic Collagen Scaffold as a Suitable Coupling Option for Round Window Vibroplasty.

Introduction: In round window vibroplasty the most efficient coupling technique for contact of the floating mass transducer (FMT) to the round window membrane (RWM) is yet to be determined. Various materials placed between the FMT and the RWM have been proposed to enable better stimulation of the cochlea. Collagenous scaffolds derived from decellularized extracellular cartilage matrices as a commercially available biomaterial are already used for other applications in ear surgery.

Results of a national web-based survey on the SARS-CoV-2 infectious state of otorhinolaryngologists in Germany.

Purpose: SARS-CoV-2 is detected on the mucosa of the upper airways to a high degree. In the course of the COVID-19 pandemic, otorhinolaryngologists (ORL) are assumed to be at high risk due to close contact with the mucosa of the upper airways. No data are yet available providing evidence that ORLs have an increased risk of infection.

Olfactory dysfunction in patients after recovering from COVID-19.

Background: Smell and taste disorders occur in COVID-19 with a high prevalence, but little is known about the duration of the symptoms. In particular, studies using validated olfactory tests are very rare to date.
