Poly-D,L-lactic acid polymer and cochlear implantation.

This case report describes a peculiar and innovative fixing procedure with a Poly-D,L-lactic acid (PDLLA) polymer in the unusual case of magnet dislodgment and rupture of the cochlear implant (CI) silicone sheath holding the magnet.

Maximum acceptable level for the determination of ECAP and ESRT in a paediatric population.

Objectives: Two of the most used objective measures are electrically evoked action potentials (ECAPs) and electrically evoked stapedius reflex thresholds (ESRTs). Although stimuli used for these measures differ considerably, both measures are influenced by subjective loudness percept. We focus on the subjective maximum acceptable loudness (MAL) to investigate if loudness sensitivity varied along the electrode array during ECAP recordings.

Cochlear implantation in children with Autism Spectrum Disorder (ASD): Outcomes and implant fitting characteristics.

Background: Little is known regarding fitting parameters and receptive and expressive language development in cochlear-implanted children (CCI) with profound sensorineural hearing loss (SHL) who are diagnosed with Autism Spectrum Disorder (ASD). The aim of the study was to evaluate a group of ASD CCI users in order to describe their ASD clinical features and CCI outcomes; report on the average electrical charge requirements; and evaluate the possible correlations between electrical and psychophysical outcomes with ASD characteristics.

Materials And Methods: A multicentre observational study of 22 ASD children implanted in four cochlear implant (CI) centers.

Irony Comprehension in Children With Cochlear Implants: The Role of Language Competence, Theory of Mind, and Prosody Recognition.

Purpose Aims of this research were (a) to investigate higher order linguistic and cognitive skills of Italian children with cochlear implants (CIs); (b) to correlate them with the comprehension of irony, which has never been systematically studied in this population; and (c) to identify the factors that facilitate the development of this competence. Method We tested 28 Italian children with CI (mean chronological age = 101 [ = 25.60] months, age range: 60-144 months), and two control groups of normal-hearing (NH) peers matched for chronological age and for hearing age, on a series of tests assessing their cognitive abilities (nonverbal intelligence and theory of mind), linguistic skills (morphosyntax and prosody recognition), and irony comprehension.

Impact of Cochlear Implant Array Placement on Speech Perception.

Purpose: To assess the role of flat panel computed tomography (FPCT) in the evaluation of cochlear implant (CI) electrode position and its relation to speech perception.

Methods: From March 2015 to March 2019, we retrospectively enrolled deaf subjects ≥ 18 years who underwent unilateral CI by one surgeon, imaged with FPCT and assessed with disyllabic words score before CI and at 6 months of follow-up. We calculated the disyllabic score difference before CI and after CI (ΔSDS) and divided the subjects in favorable and unfavorable outcome groups using the median ΔSDS as a cutoff.

Assessment of Frequency-Place Mismatch by Flat-Panel CT and Correlation With Cochlear Implant Performance.

Objective: To calculate the frequency allocation mismatch in a group of very selected cochlear implant (CI) recipients and to contrast it with the speech perception performances.

Study Design: Cross-sectional observational prospective study.

Settings: Tertiary Audiological Department, University hospital.
