[Effectiveness of cochlear implantation in children with auditory neuropathy and cochlear nerve aplasia].

Objective: The aim of this study is to assess of cochlear implantation in children with auditory neuropathy and cochlear nerve aplasia by using Categories of Auditory Performance (CAP) and Speech Intelligibility Rating (SIR).

Methods: Twenty one children with cochlear implants participated in this study. They all received cochlear implant surgery at our hospital from January 2004 to October 2010.

[Vibrant soundbridge implantation (two cases report)].

Objective: To investigate the effect of Vibrant Soundbridge (VSB) implantation.

Methods: In accordance with the indications for VSB implantation, surgeries were done for two patients who suffered from either a sensorineural or conductive hearing loss (microtia). Their preoperative auditory thresholds (0.

[Comparison of sensitivity of audiological tests to identify otitis media with effusion in newborn infants].

Objective: To investigate the sensitive factors which were used in routine audiological tests to find out otitis media with effusion (OME) in newborn infants.

Methods: Subjects of this study were 48 infants, including 31 males and 17 females, who failed in the universal newborn hearing screening. The age ranged from 1.

[Quality of life after cochlear implantation in postlingually deaf adults].

Objective: To evaluate the quality of life after cochlear implantation in adult cochlear implant recipients and to assess the applicability of Nijmegen Cochlear implant Questionnaire (NCIQ).

Methods: Thirty-two postlingually deaf patients, 19 males and 13 females, underwent cochlear implantation with the age at operation of 35.27 (18-66) during the period from 1996 to the end of 2006.

[Cochlear implantation in the ossified cochlear].

Objective: To explore the problems and describe clinical experiences associated with multichannel cochlear implantation in patients with cochlear ossification.

Methods: Seven cochlear implant cases with bilateral cochlear ossification from 1996 to 2006 in Beijing Tongren Hospital were retrospectively reviewed, 4 of which were the consequence of meningitis. Three patients' cochlear were completely ossified, 1 patient's tympanic scala was completely ossified, 1 patient's cochlear was partially ossified, and 2 patients' cochlear were partially fibrotic.

[Outcome of cochlear implantation in prelingual pediatric auditory neuropathy].

Objective: To explore the electrophysiological results and rehabilitation outcome of two prelingually deafened pediatric cochlear implant patients with auditory neuropathy.

Methods: Preoperative audiological evaluation, intra-postoperative electrically evoked auditory brainstem response (EABR) and neural response telemetry (NRT) record for the two cases were conducted in Beijing Tongren Hospital. A one year follow-up was performed.

[Auditory capability evaluation for children after cochlear implantation using meaningful auditory integration scale].

Objective: To analyze the auditory capability of preschool children before and after cochlear implantation using meaningful auditory integration scale (MAIS) questionnaire.

Methods: Eighty-two prelingually deaf patients participated in this study. They received a cochlear implant at the age of 3 to 6 years and 11 months.

[Follow-up study for newborns and infants who failed hearing screening].

Objective: To study the audiological characteristics of newborns and infants who failed hearing screening.

Methods: One hundred and six infants failed hearing screening received follow-up study with routine audiological evaluations (auditory brainstem response, distortion product otoacoustic emission, tympanometry and visual reinforcement audiometry).

Results: Sixty-five infants (61.

Comparisons between neural response imaging thresholds, electrically evoked auditory reflex thresholds and most comfortable loudness levels in CII bionic ear users with HiResolution sound processing strategies.

Conclusions: The data collected in this study indicated that first Neural Response Imaging (NRI) thresholds had a better correlation with HiResolution most comfortable loudness (M) levels than tNRI thresholds. Electrically evoked auditory reflex thresholds (EARTs) had a higher correlation with HiResolution M levels than tNRI thresholds and a lower correlation than first NRI thresholds. NRI is a very useful method for programming the cochlear implants of young children who cannot demonstrate a reliable judgment of loudness.

[Cochlear implantation in patients with inner ear malformations].

Objective: To describe clinical experiences with multi-channel cochlear implantation in patients with bilateral inner ear malformations.

Methods: Among 410 patients who received multi-channel cochlear implantations from 1996 to 2004 in Beijing Tongren Hospital, 82 patients were diagnosed with inner ear malformations and implanted. A retrospective analysis was performed about the surgical characteristics and mapping characteristics after implantation.

[Multi-channel cochlear implants in patients with Mondini malformation].

Objective: To describe clinical experiences with multi-channel cochlear implantation in patients with Mondini malformation.

Methods: Among 300 patients who received multi-channel cochlear implants from 1996 to 2002 in Beijing Tongren Hospital, 15 patients were diagnosed with Mondini malformation. A retrospective analysis was performed dealing with the surgical techniques, mapping and rehabilitations characteristics after surgery.

[Cochlear implants in children with enlargement of vestibular aqueduct].

Objective: To describe the clinical experiences with multi-channel cochlear implantation in the children with enlargement of vestibular aqueduct.

Method: Fifteen patients were diagnosed with enlargement of vestibular aqueduct and received multi-channel cochlear implantation at Beijing Tongren Hospital. A cochleostomy was performed for all patients by a standard facial recess approach to anterior inferior to the round window niche.

[Cochlear implantation in patients with inner ear malformations, clinical analysis of 25 cases].

Objective: To explore the clinical experience of multi-channel cochlear implantation in patients with bilateral inner ear malformations.

Method: Multi-channel cochlear implantation was conducted among 180 patients from 1997 to 2001. Twenty-five of them, being with inner ear malformations, were given hearing and speech rehabilitation including sound detection, word discrimination, auditory comprehension and spoken language skill development.
