Article Synopsis
  • The study aimed to evaluate the feasibility of safely drilling into the temporal bone for cochlear implant fixation, addressing the risk of complications like hematoma and cerebrospinal fluid leakage, especially in patients with thinner bones.
  • An innovative semi-automatic algorithm was developed to analyze 3D skull models, identifying the thickest areas of temporal bone and determining residual bone thickness after simulated drilling, with initial validation showing high accuracy in five test cases.
  • The algorithm offers a reliable method for assessing surgical feasibility and risks in patients with thinner temporal bones, potentially improving the safety and efficiency of cochlear implant surgeries.

Background: During the cochlear implantation procedure, the receiver/stimulator (R/S) part of the implant is fixated to prevent postoperative device migration, which could have an adverse effect on the position of the electrode array in the cochlea. We aim to compare the migration rates of two fixation techniques, the bony recess versus the subperiosteal tight pocket without bony sutures.

Methods And Analysis: This single-blind randomized controlled trial will recruit a total of 112 primary cochlear implantation adult patients, eligible for implantation according to the current standard of practice.

Hypothesis: To develop and validate the optimal design and evaluate accuracy of individualized 3D- printed surgical guides for cochlear implantation.

Background: Positioning and fixation of the cochlear implant (CI) are commonly performed free hand. Applications of 3-dimensional (3D) technology now allow us to make patient specific, bone supported surgical guides, to aid CI surgeons with precise placement and drilling out the bony well which accommodates the receiver/stimulator device of the CI.

Background: Surgical success of cochlear implantation is usually measured through speech perception and quality of life questionnaires. Although these questionnaires cover a broad spectrum of domains, they do not evaluate the consciousness of wearing a cochlear implant (CI) and how this impacts the daily life of patients. To evaluate this concept we aimed to develop and validate a standardized patient reported outcome measure (PROM) for use in cochlear implant users.

Article Synopsis
  • The study aimed to explore the current surgical practices for placing and securing cochlear implant components among surgeons worldwide.
  • A questionnaire completed by 59 surgeons revealed a preference for S-shape and C-shape incisions, with most agreeing on implantation angles of 45° or 60° and using the facial recess approach.
  • Results showed a notable shift towards techniques that prioritize preserving structures and minimizing trauma during the cochlear implantation procedure.

Objective: Given the lack of consensus on fixation techniques of the cochlear implant, this review aims to create an up-to-date overview of intra- and postoperative complications, focusing on migration of the internal receiver/stimulator (R/S) device and the electrode array.

Data Sources: On June 29, 2020 we conducted a search in PubMed, Embase, Cochrane, Web of Science, and CINAHL. Keywords were "Cochlear implant," "complication," "migration," and synonyms.
