Background And Objective: Speech comprehension in a foreign language under noise conditions presents an increased cognitive demand. For multilingual patients with cochlear implants (PwCI), this poses a particular challenge, as audiological routine diagnostics are typically conducted in the language of the clinical environment. This study investigates speech understanding in noise as well as the subjectively perceived listening effort in PwCI compared to normal-hearing (NH) individuals under both native and nonnative language conditions.

Background: Skull base osteomyelitis (SBO) is a severe disease not only because of its rapid progression and its high mortality: diagnosis and treatment are often protracted and in more than 30% of cases no causative pathogen can be detected. SBO is usually preceded by immunodeficiency, which is why opportunistic infections caused by atypical pathogens must also be taken into consideration. In consideration of the different possible entities, an interdisciplinary approach with surgical debridement, pathological sampling, microbiological testing and antimicrobiological therapy is indispensable.

Background: Cochlear implants are implanted hearing devices; instead of amplifying sounds like common hearing aids, this technology delivers preprocessed sound information directly to the hearing (ie, auditory) nerves. After surgery and the first cochlear implant activation, patients must practice interpreting the new auditory sensations, especially for language comprehension. This rehabilitation process is accompanied by hearing therapy through face-to-face training with a therapist, self-directed training, and computer-based auditory training.
View Article and Find Full Text PDFObjectives: Cochlear implants are an established and proved method for auditory rehabilitation. In addition, neuromodulation systems for treating severe movement and pain disorders are gaining importance. To date, there is limited information regarding the concurrent use of the various implanted systems and potential electromagnetic interferences.

People with single-sided deafness (SSD) or asymmetric hearing loss (AHL) have particular difficulty understanding speech in noisy listening situations and in sound localization. The objective of this multicenter study is to evaluate the effect of a cochlear implant (CI) in adults with single-sided deafness (SSD) or asymmetric hearing loss (AHL), particularly regarding sound localization and speech intelligibility with additional interest in electric-acoustic pitch matching. A prospective longitudinal study at 7 European tertiary referral centers was conducted including 19 SSD and 16 AHL subjects undergoing cochlear implantation.

Purpose: For the modeling, execution, and control of complex, non-standardized intraoperative processes, a modeling language is needed that reflects the variability of interventions. As the established Business Process Model and Notation (BPMN) reaches its limits in terms of flexibility, the Case Management Model and Notation (CMMN) was considered as it addresses weakly structured processes.
Methods: To analyze the suitability of the modeling languages, BPMN and CMMN models of a Robot-Assisted Minimally Invasive Esophagectomy and Cochlea Implantation were derived and integrated into a situation recognition workflow.

To allow for a suitable collaboration between surgeon and robot, these systems should not interrupt the surgical workflow and integrate well in existing processes. As the surgical microscope is a standard tool, present in almost every microsurgical intervention and due to it being in close proximity to the situs, it is predestined to be extended by assistive robotic systems.

Purpose: Robot-assisted surgery at the temporal bone utilizing a flexible drilling unit would allow safer access to clinical targets such as the cochlea or the internal auditory canal by navigating along nonlinear trajectories. One key sub-step for clinical realization of such a procedure is automated preoperative surgical planning that incorporates both segmentation of risk structures and optimized trajectory planning.
Methods: We automatically segment risk structures using 3D U-Nets with probabilistic active shape models.
Introduction: Sphenopalatine ganglion (SPG) stimulation is an efficient treatment for cluster headache. The target for the SPG microstimulator in the pterygopalatine fossa lies between the vidian canal and foramen rotundum, ideally two contacts should be placed in this area. However, placement according to the manufacturers recommendations is frequently not possible.

Purpose: Accurate estimation of the position and orientation (pose) of surgical instruments is crucial for delicate minimally invasive temporal bone surgery. Current techniques lack in accuracy and/or line-of-sight constraints (conventional tracking systems) or expose the patient to prohibitive ionizing radiation (intra-operative CT). A possible solution is to capture the instrument with a c-arm at irregular intervals and recover the pose from the image.
