Introduction: This study aimed to verify the influence of speech stimulus presentation and speed on auditory recognition in cochlear implant (CI) users with poorer performance.
Methods: The cross-sectional observational study applied auditory speech perception tests to fifteen adults, using three different ways of presenting the stimulus, in the absence of competitive noise: monitored live voice (MLV); recorded speech at typical speed (RSTS); recorded speech at slow speed (RSSS). The scores were assessed using the Percent Sentence Recognition Index (PSRI).
Purpose: Longitudinally verify the influence of auditory tonal thresholds obtained with transcutaneous and percutaneous bone-anchored hearing aids on speech perception in individuals with external and/or middle ear malformation and chronic otitis media.
Methods: Observational, retrospective, longitudinal follow-up study of 30 unilateral users of the transcutaneous and percutaneous Baha® system for the collection of secondary data on pure tone thresholds obtained through free field audiometry and sentence recognition threshold in silence and noise in conditions: without the prosthesis; at the time of activation; in the first month of use (post 1); and in the third month (post 2).
Results: There was a significant difference between pure tone thresholds obtained at frequencies of 3 and 4kHz with better results for the percutaneous technique at all evaluation moments.
Objective: To describe the post-operative complications and audiological results related to percutaneous bone-anchored hearing devices.
Methods: A retrospective review was conducted of 44 patients with bilateral conductive or mixed hearing loss who were implanted with unilateral Baha Connect or Ponto devices. A generalised linear model for repeated measurements was used.
Middle fossa approach has been suggested as an alternative for patients in whom other routes of electrode insertion are contraindicated. Even though there are temporal bone studies about the feasibility of introducing the cochlear implant through the middle fossa, until now, very few studies have described results when cochlear implant surgery is done through this approach. The objective of this study is to review a series of temporal bone studies related to cochlear implantation through the middle fossa and the results obtained by different surgical groups after cochlear implantation through this approach.

Background: The benefits of residual hearing preservation in cochlear implant recipients have promoted the development of atraumatic surgeries. Minimal trauma during electrode insertion is crucial for residual hearing preservation.

Objective: The present investigation evaluated the speech perception performance of patients with ossified cochlea implanted with the 24M Double Array cochlear implant, using standard and duplicated maps in each of the arrays.
Study Design: Retrospective case review.
Setting: Tertiary referral center.
Unlabelled: Neurofibromatosis 2 (NF2) is an autosomal dominant disease in which hearing loss is predominant. Auditory restoration is possible using cochlear implants (CI) or auditory brainstem implant (ABI).
Objective: To assess the auditory results of CI and ABI in NF2 patients and review the literature.
Unlabelled: The technological advances in cochlear implants and processing strategies have enabled subjects affected by severe to profound hearing loss to hear sounds and recognize speech in various different degrees. The variability of hearing outcomes in subjects with post-lingual deafness has been significant and cochlear implant indications have been extended to include an ever larger population.
Objective: This paper aims to look into the groups of post-lingual deafness patients to find where cochlear implants have yielded better outcomes than conventional hearing aids.
This study aimed to evaluate the neural response in double-array cochlear implant as well as to describe the refractory recovery and the spread of excitation functions. In a prospective study 11 patients were implanted with the double-array cochlear implant. Neural response telemetry (NRT) was performed intra-operatively.

Aim: this paper aims to analyze the use of DWI and delayed post-contrast T1-weighed imaging in the detection of recurring cholesteatomas.
Materials And Method: this is a cross-sectional prospective study that looked at 17 cholesteatoma patients postoperatively.
Background: Cochlear implant speech processors compress a wide acoustical dynamic range of sounds into a smaller electrical dynamic range. Some patients show wider electrical dynamic ranges than others and most of them have good speech perception performance. The knowledge of the average psycho-acoustical dynamic range in adults will help the audiologist program children who do not give reliable responses.

Aim: 1) to delineate a profile of receptive and expressive verbal language of children who have been using cochlear implant for five years and five years and eleven months; 2) to verify the influence of time of auditory sensorial privation in the receptive and expressive verbal language of these children.
Method: 19 children users of CI with auditory deficiency acquired before language development, who have been using CI for 5y - 5y11m and who have an average time of sensorial privation of 3y (standard deviation of 1 year).

Background: Due to the condition known as middle ear squeeze, scuba diving has become one of the main causes of barotrauma, and the acute form of this condition has been relatively well established. However, there are few reports available on clinical or laboratory findings in divers who practise repeated diving. The objective of the present study was to assess the otological effects of repeated dives.

The use of objective measures is needed to help speech processor programming. The electrically evoked compound potential (EAP), which can be assessed by neural response telemetry (NRT), is one of those objective measures.

One of these involves the precise nature of surgical intervention once the decision to operate has been made. Between June 1, 1984, and June 30, 1993, we surgically treated 220 cases of traumatic facial paralysis with good cochlear reserve by decompressing the tympanic and mastoid segments via a transmastoid approach followed by decompression of the geniculate ganglion and the distal half of the labyrinthine segment via a middle fossa approach.
