Ventilation with hyperoxia promotes cochlear bleeding in rabbits with congenital diaphragmatic hernia.

Objective: The authors hypothesized that ventilation and hyperoxia may harm the cochlea vasculature in an experimental model of Congenital Diaphragmatic Hernia (CDH) performed in rabbits.

Methods: New Zealand rabbits underwent CDH creation at 25 days of gestation (term = 30 days). CDH was created in fetuses (n = 15) and compared with Controls (n = 15).

Does the Number of Stimuli Influence the Formation of the Endogenous Components of the Event-Related Auditory Evoked Potentials?

 The number of stimuli is important to determine the quality of auditory evoked potential records. However, there is no consensus on that number in studies, especially in the sample studied.  To investigate the influence of the number of rare stimuli on forming N2 and P3 components, with different types of acoustic stimuli.

Auditory Outcomes in Adolescents with Prenatal Alcohol Exposure.

The aim of the study was to investigate three aspects of auditory function (auditory acuity, cochlear dysfunction, and auditory processing) in adolescents with fetal alcohol exposure without phenotypic changes. Fifty-one adolescents with and without intrauterine exposure to alcohol were selected from a cohort study. The summons, evaluation, and analysis of the results were carried out blindly regarding the respective exposure to alcohol.

The P300 Auditory Evoked Potential in Cochlear Implant Users: A Scoping Review.

 The P300 auditory evoked potential is a long-latency cortical potential evoked with auditory stimulation, which provides information on neural mechanisms underlying the central auditory processing.  To identify and gather scientific evidence regarding the P300 in adult cochlear implant (CI) users.  A total of 87 articles, 20 of which were selected for this study, were identified and exported to the Rayyan search software.

Surgical management of embolized jugular foramen paragangliomas without facial nerve transposition: Experience of a public tertiary hospital in Brazil.

Background: Jugular foramen paragangliomas (JFP) treatment represents a challenge for surgeons due to its close relationship with facial nerve (FN), lower cranial nerves (LCN), and internal carotid artery. Due to its hypervascularization, preoperative tumor embolization has been indicated.

Methods: Retrospective analysis of the clinical evolution of 26 patients with JFP class C/D previously embolized treated through infratemporal/cervical access without FN transposition.

Glomus jugulare in a pediatric patient: case report and literature review.

Purpose: The jugular and tympanic glomus are rare neoplasms in the general population, being even more uncommon in the pediatric population. There is considerable morbidity associated with both disease and treatment. Treatment is essentially surgical, carried out in recent years in a multidisciplinary manner using preoperative embolization associated with microsurgery and eventually adjuvant radiotherapy.

Clinical implications of intraoperative eABRs to the Evo®-CI electrode array recipients.

Introduction: Electrically evoked auditory brainstem responses provide reliable clinical information to assist professionals in the auditory rehabilitation of cochlear implant users.

Objective: This study aimed to investigate intraoperative evoked auditory brainstem response recordings in Evo®-cochlear implant electrode array recipients and its correlation with their behavioral levels and auditory performance.

Methods: This is a retrospectivey study.

Functional Impact of Tinnitus in Patients with Hearing Loss.

 Tinnitus, which is considered the third worst symptom for humans, is a common complaint among people living with hearing loss and may negatively affect the quality of life of those who have it.  To analyze the perception of the handicap in patients with tinnitus and hearing loss as well as the possible associations between the variables hearing loss, loudness, onset, frequency and annoyance by tinnitus, and the correlation between the visual analogue scale (VAS) and the Tinnitus Handicap Inventory (THI).  A total of 30 patients with complaints of tinnitus and the presence of sensorineural hearing impairment were selected for this cross-sectional, observational, and descriptive study.

Method to quantitatively assess electrode migration from medical images: Feasibility and application in patients with straight cochlear implant arrays.

To propose a method for quantitative assessment of the migration of lateral-wall, straight electrode arrays after surgery based on postoperative Cone Beam Computed Tomography (CBCT) images and automated medical image analysis techniques. A preliminary study is conducted on 19 implanted ears. For each implantation, two CBCT images are objectively analyzed.

Cross-cultural adaptation of the Amsterdam inventory for auditory disability and handicap to Brazilian Portuguese.

Introduction: Patient-reported outcome measures, inventory and or questionnaire, allow patients to present their perspective of the impact of their individual condition on a day-to-day basis, independent of the analysis of test results by the expert clinician. Outcome measures are recommended when there is evidence showing their reliability, validity and sensitivity. There are standardized patient-reported outcome measures for hearing in English language; however, other languages lack these instruments.

Relationship between Speech Perception and Level of Satisfaction of Hearing Aid Users.

 Hearing difficulties can be minimized by the use of hearing aids.  The objective of this study is to assess the speech perception and satisfaction of hearing aids users before and after aid adaptation and to determine whether these measures are correlated.  The study was conducted on 65 individuals, 54% females and 46% males aged 63 years on average, after the systematic use of hearing aids for at least three months.

Anatomical and functional evaluation of tympanoplasty using a transitory natural latex biomembrane implant from the rubber tree Hevea brasiliensis.

Biosilicate ototoxicity and vestibulotoxicity evaluation in guinea-pigs.

Unlabelled: Changes, destructions and interruptions in middle ear ossicular chain architecture may be caused by infection, trauma, tumors, congenital alterations or prior surgeries. Nonetheless, infectious and inflammatory processes, focal or generalized which affect the middle ear are the most prevalent, causing a great demand for ossiculoplasty. Biosilicato is a new material which can be used in the middle ear with the goal of reconstructing the ossicular chain.
