Factors influencing rehabilitation effect in prelingually deafened late-implanted cochlear implant users, and the construction of a nomogram.

Objectives: Our study aimed to identify potential factors that may influence rehabilitation outcomes in late-implanted adolescents and adults with prelingual deafness and to construct a user-friendly nomogram.

Design: This cross-sectional study included 120 subjects under 30 years of age who had received cochlear implantation at a single medical centre. The Categories of Auditory Performance (CAP) scale was used to evaluate the rehabilitation outcomes.

The use of the MUSS and the SIR scale in late-implanted prelingually deafened adolescents and adults as a subjective evaluation.

The SIR scale has been widely used to measure speech improvement in late-implanted prelingually deafened adolescents and adults. However the ceiling effect of the SIR scale may lead to the loss of some information. To evaluate the oral ability of late-implanted prelingually deafened adolescents and adults using the MUSS and SIR scale and to analyse the relationship between the SIR score and the MUSS score.

Interaction of tinnitus suppression and hearing ability after cochlear implantation.

Objectives: To study the postoperative impact of cochlear implants (CIs) on tinnitus, as well as the impact of tinnitus on speech recognition with CI switched on.

Methods: Fifty-two postlingual deafened CI recipients (21 males and 31 females) were assessed using an established Tinnitus Characteristics Questionnaire and Tinnitus Handicap Inventory (THI) before and after cochlear implantation. The tinnitus loudness was investigated when CI was switched on and off in CI recipients with persistent tinnitus.

One-stage coclear implantation via a facial recess approach in children with otitis media with effusion.

Objective: To investigate surgical indications, operative techniques, complications and auditory and speech rehabilitation for cochlear implant (CI) in children with otitis media with effusion (OME).

Material And Methods: This is a retrospective review of records of 24children with bilateral profound sensorineural hearing loss and OME who were implanted during January 2011 to November 2014 in the Department of Otorhinolaryngology and Head and Neck Surgery at the PLA Hospital, using one-stage implantation via the facial recess approach and round window insertion. The incus was removed in 8 cases during the implantation procedure.

[Effect of cochlear implantation on bilateral perceived tinnitus of postlingually deafened patients].

Objective: The aim of the study was to evaluate the effects of cochlear implantation on bilateral perceived tinnitus of postlingually deafened patients.

Method: Total of 32 postlingually deafened cochlear implant recipients (13 males, 19 females; 31 unilateral,1 bilateral cochlear implantation) with bilateral tinnitus were assessed by Tinnitus Handicap Inventory (THI) before and after implantation. Furthermore, characteristics information of tinnitus were recorded to analyze the variety of tinnitus.

Determination of benefits of cochlear implantation in children with auditory neuropathy.

Background: Auditory neuropathy (AN) is a recently recognized hearing disorder characterized by intact outer hair cell function, disrupted auditory nerve synchronization and poor speech perception and recognition. Cochlear implants (CIs) are currently the most promising intervention for improving hearing and speech in individuals with AN. Although previous studies have shown optimistic results, there was large variability concerning benefits of CIs among individuals with AN.

NRT test in auditory neuropathy patients with cochlear implants.

Conclusion: In patients with auditory neuropathy (AN), waveforms of neural response telemetry (NRT) could be present, showing characteristics of low incidence, low differentiation, and large variation.

Objective: To study the characteristics of NRT in AN patients who had received cochlear implants (CIs).

Methods: NRT data for seven AN patients who had received Nucleus CIs were retrospectively analyzed.

Vibrant Soundbridge implantation via the third window in two Chinese patients with severe bilateral congenital aural atresia.

Conclusion: In patients with undeveloped vestibular/oval windows and inaccessible round windows, Vibrant Soundbridge (VSB) implantation performed by placing the transducer into a reconstructed window on the inner tympanum wall demonstrated significant improvement in hearing and verbal communication ability.

Objective: To report our surgical experience with new placement of the VSB in pediatric patients with undeveloped vestibular windows, inaccessible round windows, and severe bilateral congenital aural atresia (CAA).

Methods: In two patients with bilateral CAA selected for middle ear implantation, CT scans revealed severe middle ear malformation including inaccessible round windows, absence of vestibular/oval windows, and abnormal facial nerve anatomy.
