Objective: To evaluate the esthetic and functional results of an osteoplastic flap for mastoid cavity closure in cochlear implant surgery.
Study Design: Double-blind, prospective, randomized clinical trial.
Setting: tertiary referral center.
Purpose: To evaluate the influence of obstructive sleep apnea (OSA) on the P300 response of auditory event-related potentials (ERPs) and to correlate the electrophysiological findings with OSA severity.
Methods: Patients with no OSA and mild, moderate, and severe OSA according to polysomnography (PSG) with normal hearing and no comorbidities were studied. Individuals with a body mass index (BMI) ≥ 40 kg/m, hypertension, diabetes, dyslipidemia, the use of chronic medications, and a risk of hearing loss were excluded.

Objective: The aim of this study was to determine whether the auditory skills presented by five-year-old children can predict their performance in auditory processing (AP) tests at seven years old.
Design: Thirty-five children were evaluated for AP at two different times. At evaluation 1, the children were between 5 years 2 months and 6 years 1 month of age, and at evaluation 2, they were between 7 years 1 month and 7 years 8 months of age.
Introduction: Obstructive sleep apnea causes changes in normal sleep architecture, fragmenting it chronically with intermittent hypoxia, leading to serious health consequences in the long term. It is believed that the occurrence of respiratory events during sleep, such as apnea and hypopnea, can impair the transmission of nerve impulses along the auditory pathway that are highly dependent on the supply of oxygen. However, this association is not well established in the literature.

Methods: This was a cross-sectional study that investigated 40 individuals between 30 and 50 years old, who were divided into groups with and without systemic arterial hypertension, using data from high-frequency audiometry, transient-evoked otoacoustic emissions and distortion-product otoacoustic emissions. The results were compared with those from groups of normal-hearing individuals, with and without systemic arterial hypertension, who underwent the pure-tone audiometry test.
Objective: To identify a cutoff value based on the Percentage of Consonants Correct-Revised index that could indicate the likelihood of a child with a speech-sound disorder also having a (central) auditory processing disorder .
Methods: Language, audiological and (central) auditory processing evaluations were administered. The participants were 27 subjects with speech-sound disorders aged 7 to 10 years and 11 months who were divided into two different groups according to their (central) auditory processing evaluation results.
Introduction: Abnormalities in auditory function of newborns may occur not only because of preterm birth, but also from the use of medications and from diseases related to prematurity.
Objective: To analyze the inhibitory effect from stimulation of the olivocochlear efferent system on transient evoked otoacoustic emissions in preterm neonates, comparing these data with those from full-term neonates.
Methods: This was a prospective, cross-sectional, contemporary cohort study with 125 neonates, pooled into two groups: full-term (72 full-term neonates, 36 females and 36 males, born at 37-41 weeks of gestational age); and preterm (53 neonates, 28 males and 25 females, born at ≤36 weeks of gestational age, evaluated at the corrected gestational age of 37-41 weeks).
Introduction: Middle ear muscle reflex (MEMR) evaluation assists in diagnosing hearing problems because normal responses depend on preconditions of a healthy auditory system. Studies in neonates recording the acoustic reflex with 226Hz probes have described high rates of absence. Other studies using a high frequency probe have found higher rates of presence in normal neonates.

Methods: A total of 243 students with a mean age of 8.3 years participated in the study.
Purpose: To verify if there is an association between temporal auditory tests and phonological awareness in individuals with reading and writing disorders.
Methods: Sixteen children were subjects of this study, aged between 7 and 12 years old, who had reading and writing disorders confirmed after specific assessment. All participants underwent phonological awareness assessment using CONFIAS test.
Purpose: To characterize the normal values of acoustic energy reflectance obtained with pure-tone stimulation in neonates prior to hospital discharge.
Methods: Seventy-seven infants (37 girls and 40 boys) were evaluated by measuring acoustic reflectance using pure-tone stimuli, transient-evoked otoacoustic emissions, and tympanometric probe frequencies of 226 Hz and 1 kHz.
Results: At low frequencies (258-750 Hz), greater energy reflectance was observed, while at medium frequencies (1-3 kHz), greater energy absorption was observed.
Introduction: The resonant frequency is the probe frequency in which susceptance is 0 due to the neutralization of the forces of mass and stiffness components that control the middle ear. This frequency can be evaluated by multifrequency tympanometry, and the normality value for adults ranges 800-1,200 Hz. Studies about resonant frequency in children are scarce.

Methods: Fifteen subjects with phonological disorder (pure tone thresholds ≤20 dBHL from 0.50 to 4 kHz, and age between 7 years and 10 years and 11 months) were evaluated, divided into three groups:
Control Group: five subjects (mean age 9.
Background: Distortion product otoacoustic emission measures (DPOAE) verifies, among other characteristics, the emergence and growth rate of the DPOAE response according to sound stimulus intensity (growth curve).
Aim: To estimate the DPOAE threshold in neonates according to the DPOAE growth curve at 2 kHz and 4 kHz, with stimulus presentation ranging between 35 and 70 dB SPL.
Method: Participants were 51 neonates, with 24 to 84 hours of life and with no indication of risk for hearing impairment.
Background: Audiological evaluation of parents of individuals with autosomal recessive hearing loss.
Aim: To study the audiological profile of parents of individuals with autosomal recessive hearing loss, inferred by family history or by molecular tests that detected heterozygous mutations in the GJB2 gene. This gene codes Connexin 26.
Background: the Gaps-in-Noise (GIN) test assesses the auditory temporal resolution skill. Studies have described the GIN test an instrument of easy application and with good sensitivity and specificity.
Aim: to compare the results of the GIN test in normal listeners with and without tinnitus and to correlate the obtained results with pure tone thresholds and age.
Our aim was to analyze the influence of subtle cochlear damage on temporal auditory resolution in tinnitus patients. Forty-eight subjects (hearing threshold
