Cochlear Implant Activation in the Immediate Postoperative Period in the Operating Room.

 Cochlear implant (CI) activation usually takes place at ∼ 30 days postoperative (PO). In our service, CI surgery is performed with local anesthesia and sedation, so activation is possible with the patient's cooperation, immediately after the CI surgery, still in the operating room (OR).  The objective of the present study was to provide the patient with hearing experience with the CI and to assess auditory perception immediately after surgery while still in the OR, as well as to compare impedance telemetry (IT), neural response telemetry (NRT), and comfort (C) level at two moments: in the OR and at the definitive activation, ∼ 30 days PO.

Neural recovery function of the auditory nerve in cochlear implant surgery: Comparison between different regions of the cochlea.

Introduction: Cochlear implants allow measures of neural function, through Neural response telemetry (NRT) and Auditory nerve recovery function (REC). These help in programming the speech processor and understanding the auditory system. However, not many studies have evaluated and compared these in different regions of the cochlea.

Neural Recovery Function of the Auditory Nerve in Cochlear Implant Surgery: Comparison between Prelingual and Postlingual Patients.

 Cochlear implants (CIs) enable objective measures of the neural function in implanted patients through the measurements of the neural response telemetry (NRT) and of the Auditory nerve Recovery Function (REC). These measurements help in programming the speech processor and understanding the auditory system.  To compare the NRT and the REC in prelingual and postlingual implanted patients.

Facial Nerve Intraoperative Monitoring in Otologic Surgeries under Sedation and Local Anesthesia - A Case Series and Literature Review.

 Local anesthesia with sedation has been employed for an increasingly number of otolaryngology procedures, and might be associated with lower surgical morbidity and costs. Facial nerve monitoring is often advisable in otology to minimize the risks of injuries to this cranial nerve, but the principles, techniques and parameters involved have only been studied for procedures under general anesthesia.  To report the preliminary outcomes of intraoperative facial nerve monitoring during otologic procedures under sedation and local anesthesia.

Use of remote control in the intraoperative telemetry of cochlear implant: multicentric study.

Introduction: The conventional evaluation of neural telemetry and impedance requires the use of the computer coupled to an interface, with software that provides visualization of the stimulus and response. Recently, a remote control (CR220) was launched in the market, that allows the performance of intraoperative tests with minimal instrumentation.

Objective: To evaluate the agreement of the impedance values and neural telemetry thresholds, and the time of performance in the conventional procedure and by the remote control.

Simultaneous cochlear implantation as a therapeutic option in vestibular schwannoma surgery: case report.

Hearing loss is the most common symptom of vestibular schwannomas (VSs). The management of these lesions includes observation, radiosurgery, and microsurgical resection. Hearing preservation and rehabilitation are the major challenges after the tumor treatment.

Auditory Nerve Recovery Function in Cochlear Implant Surgery with Local Anesthesia and Sedation versus General Anesthesia.

Objective: To analyze auditory nerve recovery function (REC), comparing the results after local anesthesia and sedation with those after general anesthesia.

Methods: This was a prospective, cross-sectional and descriptive study in a tertiary referral center hospital. We included all patients (37 ears) who underwent surgery for cochlear implant under either general anesthesia or local anesthesia and sedation during 3 years.

Subjective and Objective Analyses of Voice Improvement After Phonosurgery in Professional Voice Users.

Objectives: To evaluate voice improvement after phonosurgery by subjective and objective voice analysis.

Design: Prospective observational analytic group study.

Methods: This study was conducted from January 2012 to December 2013.

Cochlear implant surgery with local anesthesia and sedation: comparison with general anesthesia.

Objectives: The purpose of this study is to evaluate the possibility of performing cochlear implant surgery under local anesthesia and sedation and to evaluate the response of patients under sedation at the time of neural telemetry, comparing the differences with general anesthesia.

Patients: Twenty adult patients with bilateral sensorineural profound hearing loss submitted to cochlear implant surgery under general anesthesia and 20 patients under local anesthesia and intravenous sedation in the period from February 2011 to February 2012. The study was approved by the ethical committee of the institution.

A comparison between neural response telemetry via cochleostomy or the round window approach in cochlear implantation.

Unlabelled: There are two techniques for cochlear implant (CI) electrode placement: cochleostomy and the round window (RW) approach.

Objective: This study aims to compare neural response telemetry (NRT) results immediately after surgery to check for possible differences on auditory nerve stimulation between these two techniques.

Materials And Methods: This is a prospective cross-sectional study.

Cognitive evoked potentials and central auditory processing in children with reading and writing disorders.

Unlabelled: Learning disorders are often magnified by auditory processing disorders (APD).

Objective: This paper aims to verify whether individuals with reading and writing disorders and P300 latencies above the average also present altered Staggered Spondaic Word (SSW) and speech-in-noise test results suggestive of APD.

Materials And Methods: This is a cross-sectional cohort study.

Local anesthesia for cochlear implant surgery: a possible alternative.

Unlabelled: The aim of this paper is to illustrate the possibility of performing a cochlear implant surgery with local anesthesia and sedation, the anesthetic technique and the advantages of that in comparison to a general anesthesia.

Aims: prospective study demonstrating the possibility of doing cochlear implant surgery under local anesthesia and sedation.

Materials And Methods: we describe three successful cases operated under local anesthesia, including neural telemetry and the conditions the patient presented after the surgery, with a very good recovery and no complications during and after the procedure.

Event-related potentials (P300) and neuropsychological assessment in boys exhibiting Duchenne muscular dystrophy.

Objective: To examine auditory cognitive evoked potentials (P300 potentials) and neuropsychological dysfunction in patients with Duchenne muscular dystrophy (DMD).

Method: P300 potentials and neuropsychological test results were obtained from 16 healthy control boys and 20 DMD patients. Full Intelligence Quotients (IQ) were estimated for patients and control group.
