: Since the beginning of 2020, the world has been confronted by the Covid-19 pandemic. The lock-down aims to limit the circulation of the virus and thus avoid overwhelming healthcare systems. ⋯ Literature has previously reported other human coronaviruses in the middle ear and mastoid, suggesting a risk of infection to staff during ear surgery where aerosolizing procedures are usually used. The aim of this article is to propose a strategy for planning consultations and surgeries for ear and lateral skull base diseases, in the context of the current active evolution of the pandemic and of the future gradual recovery to normal practice.

Review
Machine Learning and Cochlear Implantation-A Structured Review of Opportunities and Challenges.
The use of machine learning technology to automate intellectual processes and boost clinical process efficiency in medicine has exploded in the past 5 years. Machine learning excels in automating pattern recognition and in adapting learned representations to new settings. Moreover, machine learning techniques have the advantage of incorporating complexity and are free from many of the limitations of traditional deterministic approaches. Cochlear implants (CI) are a unique fit for machine learning techniques given the need for optimization of signal processing to fit complex environmental scenarios and individual patients' CI MAPping. However, there are many other opportunities where machine learning may assist in CI beyond signal processing. The objective of this review was to synthesize past applications of machine learning technologies for pediatric and adult CI and describe novel opportunities for research and development. ⋯ The relationship between CI and artificial intelligence is strengthening with a recent increase in publications reporting successful applications. Considerable effort has been directed toward augmenting signal processing and automating postoperative MAPping using machine learning algorithms. Other promising applications include augmenting CI surgery mechanics and personalized medicine approaches for boosting CI patient performance. Future opportunities include addressing scalability and the research and clinical communities' acceptance of machine learning algorithms as effective techniques.

By discussing the design, findings, strengths, and weaknesses of available studies investigating the influence of angular insertion depth on speech perception, we intend to summarize the current status of evidence; and using evidence based conclusions, possibly contribute to the determination of the optimal cochlear implant (CI) electrode position. ⋯ All included studies are characterized by methodological flaws, and therefore, evidence-based conclusions regarding the influence of angular insertion depth cannot be drawn to date.

Review
Management of Sigmoid Sinus Associated Pulsatile Tinnitus: A Systematic Review of the Literature.
Although studies demonstrate 4 to 20% of patients with pulsatile tinnitus (PT) have associated sigmoid sinus anomalies, no consensus exists regarding optimal management. Our objective was to perform a systematic review exploring surgical and endovascular intervention of PT caused by sigmoid sinus anomalies. ⋯ PT as a result of sigmoid sinus diverticula, aneurysms, and dehiscence is a rare, but largely treatable condition. Available interventions include SSW R/R, endovascular intervention, and cardiac U-clip techniques. In SSW R/R, bone pate, unspecified soft-tissue graft, and bone cement had the highest rates of PT resolution. While temporalis fascia and autologous bone chips were the materials most commonly used, they had significantly lower rates of PT resolution compared with the other materials, with the exception of auricular cartilage and bone cement. Most episodes of recurrence are resolved with medical management or a revision procedure. This study serves to summarize the current state of knowledge on the treatment of pulsatile tinnitus across disciplines.
