Abstract
Prevalence of hearing loss in children with autism spectrum disorder (ASD) is uncertain, as it is more challenging to assess hearing function in children with developmental difficulties (DD). We aimed to determine the prevalence and profiles of hearing loss in preschool children with ASD in a Southeast-Asian population who passed newborn hearing screening. A retrospective study of preschool children with DD (ASD, Global Developmental Delay (GDD), and Speech and Language Delay (SLD)) attending the Child Development Unit (CDU) at our hospital was performed. Three hundred and thirty-three children (ASD: n = 129; GDD: n = 110; and SLD: n = 94) underwent hearing assessments. Of these, 10.8% of children (n = 36, comprising 15 with ASD, 12 with GDD and 9 with SLD) had confirmed hearing loss. Hearing loss was predominantly bilateral in children with ASD and GDD; in those with SLD, unilateral and bilateral hearing loss were equally common. Conductive hearing loss occurred as frequently as sensorineural hearing loss in children with ASD and SLD, but was the dominant subtype in those with GDD. Moderate to severe hearing loss (n = 2) was noted only in children with ASD. Children with ASD and GDD required significantly more audiology visits and procedures to obtain conclusive hearing test results, compared to those with SLD. The need to identify hearing loss and monitor for resolution is particularly important in vulnerable populations with communication deficits, such as in those with ASD.

Polspoel S, Moore DR, Swanepoel DW, Kramer SE, Smits C. Sensitivity of the antiphasic digits-in-noise test to simulated unilateral and bilateral conductive hearing loss. Int J Audiol 2023; 62:1022-1030. [PMID: 36121040 DOI: 10.1080/14992027.2022.2119611] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2022] [Accepted: 08/28/2022] [Indexed: 11/05/2022]
Abstract
OBJECTIVES The objective of this study is (1) to assess whether the presentation level of the antiphasic digits-in-noise (DIN) test affects the speech recognition threshold (SRT), (2) to evaluate how accurately simulated unilateral and bilateral conductive hearing loss is detected (CHL) and (3) to determine whether increasing the presentation level normalises the antiphasic DIN SRT. DESIGN Participants performed antiphasic and diotic DINs at different presentation levels with unilateral, bilateral or no earplugs. STUDY SAMPLE Twenty-four and twelve normal hearing adults. RESULTS Without earplugs, antiphasic DIN SRTs did not differ between 60 and 80 dB SPL. At 60 dB SPL, the antiphasic DIN correctly classified 92% of the unilateral earplug cases; the diotic DIN 25%. The binaural intelligibility level difference did not differ between the no-earplug condition and the condition with bilateral earplugs when the presentation was increased with the attenuation level. CONCLUSIONS In normal hearing participants, diotic and antiphasic DIN SRTs are independent of presentation level above a minimum level of 60 dB SPL. The antiphasic DIN is more sensitive than the diotic DIN for detecting unilateral CHL; not for bilateral CHL. The effect of CHL on DIN SRTs can be largely compensated by increasing the presentation level. Audibility plays an important role in the antiphasic and diotic DIN.

Impact of palatoplasty techniques on tympanic membrane findings and hearing prognosis in children with cleft palate. Int J Pediatr Otorhinolaryngol 2023; 174:111747. [PMID: 37820571 DOI: 10.1016/j.ijporl.2023.111747] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Revised: 09/14/2023] [Accepted: 09/25/2023] [Indexed: 10/13/2023]
Abstract
OBJECTIVE Children with cleft palate (CP) are at high risk of developing otitis media with effusion (OME) due to Eustachian tube (ET) dysfunction. Palatoplasty has been reported to decrease the frequency of middle ear disease and improve ET function, and although various techniques have been developed, there is no consensus on the differences in the impact of different techniques on the middle ear. The purpose of this study was to determine the differential effects of palatoplasty on middle ear function and hearing. METHODS We performed a retrospective observational survey of pediatric patients who underwent palatoplasty for CP between June 2010 and October 2018 at Tohoku University Hospital. Cases were divided into three groups depending on the palatoplasty procedures performed: the push-back palatoplasty group, the two-flap palatoplasty group, and the Furlow double-opposing Z-plasty group. We examined the differences in clinical characteristics between patients who underwent each procedure. The primary outcome variable was tympanic membrane (TM) findings, and the secondary outcome was hearing test results. RESULTS Children who underwent the two-flap palatoplasty had a higher tympanostomy tube (TT) insertion rate and a higher total number of TT insertions than those who underwent the Furlow double-opposing Z-plasty or the push-back palatoplasty. The TM retraction rate tended to be lower in the Furlow double-opposing Z-plasty group than in the push-back palatoplasty group or the two-flap palatoplasty group. The hearing test results at the last visit were not significantly different among the three groups. CONCLUSIONS Children who underwent the two-flap palatoplasty had a higher rate of TT insertions, potentially increasing the risk of TM perforation. In contrast, the Furlow double-opposing Z-plasty group had a lower tendency for TM regression, possibly due to improved ET function and reduced incidence of OME. It is important to understand the advantages and disadvantages of each technique before selecting one suitable for the child's cleft and arch width. Additionally, it is important to conduct regular follow-up of TM findings and hearing test results even after palatoplasty.

Abstract
OBJECTIVE Describe the ear and hearing outcomes in Aboriginal infants in an Australian urban area. DESIGN Aboriginal infants enrolled in the Djaalinj Waakinj prospective cohort study had ear health screenings at ages 2-4, 6-8 and 12-18 months and audiological assessment at ∼12 months of age. Sociodemographic, environmental characteristics, otoscopy, otoacoustic emissions, tympanometry and visual reinforcement audiometry data were collected. STUDY SAMPLE 125 infants were enrolled in the study; 67 completed audiological assessment, 62, 54, and 58 of whom attended ear screenings at 2-4, 6-8 and 12-18 months. RESULTS Of the children that attended the audiological assessment, 36.5%, 50% and 64.3% of infants had otitis media (OM) at 2-4, 6-8 and 12-18 months. Using a 10 dB correction factor, 44.8% of infants had hearing loss (HL) (≥ 25 dB HL) at ∼ 12 months of age. More males (X2=5.4 (1df, p = 0.02)) and infants with OM at audiological assessment (X2=5.8 (1df, p = 0.02)) had HL. More infants that used a pacifier at 12-18 months of age had HL (X2=4.7 (1df, p = 0.03)). CONCLUSION Aboriginal infants in an urban area have high rates of HL and OM, which requires early surveillance and timely treatment to reduce the medical and developmental impacts of OM and HL.

Abstract
OBJECTIVE Infants diagnosed with a conductive hearing loss (CHL) are at increased risk of developmental delays. Using a sample of infants diagnosed with CHL through UNHS, this study aimed to investigate the relationship between specific demographic or clinical characteristics and 1) occasions of service to reach a hearing diagnosis and 2) the profile of CHL. METHODS Retrospective analysis was conducted for all infants with CHL born between 01/01/2007 and 31/12/2018 who had received UNHS. Chi squared analysis was conducted on data from 1208 records. RESULTS Infants with ≥1 risk factor for hearing loss were more likely to attend more than three occasions of service. Infants who were bilateral refer/medical exclusion, Torres Strait Islander, had ≥1 risk factors for hearing loss or were born pre-term had greater proportions of bilateral CHL than unilateral CHL. Mild to moderate was the most frequent degree of CHL, although a unilateral or bilateral CHL did not have an association with the severity of CHL. Compared to other risk factors, infants with a syndrome had greater proportions of bilateral than unilateral CHL. Risk factors of craniofacial abnormality, prolonged ventilation, or syndrome had greater proportions of mild to moderate CHL than moderate or greater. On average, infants were diagnosed with a CHL at 37.29 weeks of age. CONCLUSION These findings highlight the relationship between clinical/demographic characteristics and occasions of service to diagnose CHL in children, including the CHL profile. An understanding of this relationship may help clinicians to better plan, assess and manage infants diagnosed with a CHL through UNHS.

Abstract
Children with a history of temporary conductive hearing loss (CHL) during early development may show long-term impairments in auditory processes that persist after restoration of normal audiometric hearing thresholds. Tones in noise provide a simplified paradigm for studying hearing in noise. Prior research has shown that adults with sensorineural hearing loss may alter their listening strategy to use single-channel energy cues for tone-in-noise (TIN) detection rather than rove-resistant envelope or spectral profile cues. Our objective was to determine the effect of early CHL on TIN detection in healthy children compared to controls. Children ages 4-7 years, with and without a history of CHL due to otitis media with effusion (OME) before age 3 years, participated in a two-alternative forced choice TIN detection task. Audiometric thresholds were normal at the time of testing. Thresholds for detection of a 1000 Hz tone were measured in fixed-level noise and in roving-level noise that made single-channel energy cues unreliable. Participants included 23 controls and 23 with a history of OME-related CHL. TIN thresholds decreased with increasing age across participants. Children in both groups showed similar TIN sensitivity and little or no threshold elevation in the roving-level condition compared to fixed-level tracks, consistent with use of rove-resistant cues. In contrast to older listeners with sensorineural hearing loss, there was no detectable change in TIN sensitivity with roving level for children with a history of OME-related CHL.

Abstract
BACKGROUND Binaural hearing is of utmost importance for communicating in noisy surroundings and localizing the direction of sound. Unilateral hearing loss (UHL) affects the quality of life in both childhood and adulthood, speech development, and academic achievements. Sound amplification using air-conducting hearing aids (HAs) is a common option for hearing rehabilitation of UHL. The processing time of digital HAs can significantly delay the acoustic stimulation in 3 to 10 milliseconds, which is far longer than the maximal natural interaural time difference (ITD) of 750 microseconds. This can further impair spatial localization in these patients. PURPOSE We sought to assess whether HA effects on ITD and interaural level difference (ILD) impair localization among subjects with unilateral conductive hearing loss (UCHL). RESEARCH DESIGN "Normal"-hearing participants underwent localization testing in different free field settings. STUDY SAMPLE Ten volunteers with "normal"-hearing thresholds participated. INTERVENTION Repeated assessments were compared between "normal" (binaural) hearing, UCHL induced by insertion of an inactivated HA to the ear canal (conductive HL), and amplification with a HA. RESULTS In UCHL mode, with HA switched-off, localization was significantly impaired compared to "normal" hearing (NH; η2 = 0.151). Localization error was more pronounced when sound was presented from the front and from the side of the occluded ear. When switched-on, amplification with HAs significantly improved localization for all participants compared to UCHL. Better localization with HAs was seen in high frequencies compared to low frequencies (η2 = 0.08, 0.03). Even with HAs, localization did not reach that of NH (η2 = 0.034). CONCLUSION Mild UCHL caused localization to deteriorate. HAs significantly improved sound localization, albeit the delay caused by the device processing time. Most of the improvements were seen in high-frequency sounds, representing a beneficial effect of amplification on ILD. Our results have potential clinical value in situations of mild CHL, for instance, otitis media with effusion.

Abstract
OBJECTIVE To determine the cumulative 24-month incidence of middle ear effusion (MEE) among tracheostomy-dependent children requiring ventilatory support. METHODS A prospective longitudinal cohort study included all children under 2 years of age with a tracheostomy placed at a tertiary care children's hospital between 2015 and 2020 that obtained at least one tympanometry exam. The development of MEE, defined as a flat tympanogram with normal external canal volume, and mechanical ventilation requirement at examination were recorded. RESULTS Ninety-four children with a mean age at tracheostomy of 5.4 months (SD: 3.7) were included. During a mean follow-up of 18.3 months (SD: 14.6) (median: 14.1 months, interquartile range: 6.6-27.8), 192 tympanometry examinations were obtained with 59% (114/192) while requiring mechanical ventilation. Within 24 months after tracheostomy, 56.5% (95% CI: 48.9-64.4%) of children developed at least one MEE. Among those on mechanical ventilation, 74.0% (95% CI: 65.6-82.5%) developed MEE compared to 31.2% (95% CI: 21.4-44.0%) not on mechanical ventilation (HR: 2.97, 95% CI: 1.46-6.05, P = .003). A persistent MEE on two consecutive exams was not statistically more common for children on a ventilator (OR: 0.64, 95% CI: 0.01-6.95, P = .70). When controlling for age at exam, craniofacial syndrome, and newborn hearing test results on logistic regression, ventilator-dependence significantly predicted the presence of MEE (OR: 2.34, 95% CI: 1.18-4.68, P = .02). CONCLUSION Children with a tracheostomy were more likely to develop MEE when requiring mechanical ventilation. Clinicians should recognize this risk factor and appropriately assess for development of MEE to mitigate adverse speech and language development outcomes in this vulnerable population.

Abstract
OBJECTIVE Cleft palate (CP) in children is frequently complicated by otitis media with effusion (OME) due to Eustachian tube dysfunction. Although tympanostomy tube (TT) placement can be beneficial in the treatment of OME to prevent short-term hearing loss, there is no consensus regarding the indications for and timing of TT insertion. The present study was performed to define the safety and effectiveness of simultaneous TT placement with palatoplasty during the language-acquisition period. METHODS We retrospectively reviewed the medical charts of pediatric patients who underwent palatoplasty for CP in a tertiary medical center, Kyoto University Hospital, from June 2010 to October 2018. The TT retention time was estimated using the Kaplan-Meier method. The incidence of OME recurrence was compared among four Veau classification groups based on the patients' sex, type of CP, median TT retention time, and type of fluid. RESULTS Seventy-six subjects (150 ears) were enrolled in the study. The median follow-up duration was 48.7 months (range, 18.2-108.0 months) after the first TT placement. A first TT retention time of <20.1 months was a significant risk factor for OME recurrence. Subjects with maxillofacial anomaly complex and subjects with cleft lip and palate and an alveolar cleft showed a significantly higher OME recurrence rate than subjects with clefts only in the hard and/or soft palate. There was no significant difference in the occurrence of sequelae between subjects with only a single TT placement and subjects with more than one TT placement. CONCLUSIONS Based on the findings of the present study, it is reasonable to perform TT insertion at the same time as palatoplasty on patients who meet the indications. This technique may reduce the number of times the patient requires general anesthesia and maintain good middle ear condition during the period of language acquisition between 1 and 3 years of age.

Abstract
Early identification, treatment, and medical evaluation of childhood hearing loss are essential to promoting language and social development, regardless of their age of presentation. Evaluation of hearing loss in children should prioritize reversible and treatable causes. Multiple algorithms have been established to address the changing prevalence of genetic or infectious contributions to hearing loss and include recommendations on laboratory testing, imaging, and genetic testing. Despite these recommendations, significant practice variation remains on assessing the etiology of hearing loss in children.

Abstract
BACKGROUND Children with cleft palate are at high risk of both conductive hearing loss and cleft speech characteristics (CSCs) yet there is limited research to understand whether hearing loss impacts speech development in this population by contributing to the development of CSCs. AIMS This study used data from a large national cohort study in the UK (The Cleft Collective) to explore the relationship between those with a history of diagnosed hearing loss and presence of CSCs in children with cleft palate (+/- cleft lip) aged between 18 and 24 months. METHOD Speech and Language Therapists (SLTs) provided uniformed information from assessment for 123 participants who had been recruited to the Cleft Collective study. History of diagnosed hearing loss, intervention for hearing loss, and presence of CSCs were reported. A consonant inventory for each participant was completed. Statistical analysis of relationships between hearing loss and CSCs and analysis of consonant inventories was undertaken to provide information related to speech acquisition and its relationship with hearing. RESULTS There was a statistically significant relationship between history of diagnosed hearing loss and presence of CSCs (p < 0.05). Analysis of the consonant inventories highlighted that children with diagnosed hearing loss used fewer oral consonants compared to those with normal hearing (p < 0.05) CONCLUSION: This study provides some evidence that a conductive hearing loss can affect speech in children with cleft palate resulting in CSCs developing. Therefore, children with cleft palate should be closely monitored by audiology from birth to ensure that hearing is optimised for speech and language development. SLT services should also closely monitor the speech development of those children where a hearing loss has been identified, so that early intervention can be provided if appropriate. Continued data collection, with a large sample of children, will provide additional evidence regarding how this hearing loss is best managed. It will also allow increased knowledge of the long term impact of conductive hearing loss on speech development in children with cleft palate.

Improving the Differential Diagnosis of Otitis Media With Effusion Using Wideband Acoustic Immittance. Ear Hear 2021; 42:1183-1194.

Abstract
OBJECTIVES The objective of this work is to determine whether there is a systematic effect of middle ear effusion volume on wideband acoustic immittance in children with surgically confirmed otitis media with effusion. DESIGN Wideband acoustic immittance was measured in 49 ears from children (9 months to 11 years) who had a diagnosis of otitis media with effusion and compared to 14 ears from children (10 months to 10 years) without a recent history of otitis media. For children with otitis media with effusion, wideband acoustic immittance testing took place in the child's preoperative waiting room before surgical placement of tympanostomy tubes. Testing was completed in a pressurized condition (wideband tympanometry) for all ears as well as in an ambient condition in a subset of ears. Intraoperative findings regarding effusion volume were reported by the surgeons immediately before tube placement and confirmed following myringotomy. This classified the volume of effusion as compared to middle ear volume categorically as either full, partial, or clear of effusion. The type of wideband acoustic immittance explored in this work was absorbance. Absorbance responses were grouped based on effusion volume into one of four groups: full effusions, partial effusions, ears clear of effusion at the time of surgery, and normal control ears. Standard tympanometry was also completed on all ears. RESULTS Absorbance is systematically reduced as the volume of the middle ear effusion increases. This reduction is present at most frequencies but is greatest in the frequency range from 1 to 5 kHz. A multivariate logistic regression approach was utilized to classify ears based on effusion volume. The regression approach classified ears as effusion present (full and partial ears) or absent (clear ears and normal control ears) with 100% accuracy, ears with effusion present as either partial or full with 100% accuracy, and ears without effusion as either normal control ears or ears clear of effusion with 75% accuracy. Regression performance was also explored when the dataset was split into a training set (70% of the data) and a validation test set (30% of the data) to simulate how this approach would perform on unseen data in a clinical setting. Accuracy, sensitivity, specificity, and area under the receiver operating characteristic curve are reported. Overall, this approach demonstrates high sensitivity and specificity for classifying ears as effusion being present or absent and as present effusions being full or partial with areas under the curve ranging from 1 to 0.944. Despite the lack of effusion present in both clear ears and normal control ears, this approach was able to distinguish between these ears, but with a more moderate sensitivity and specificity. No systematic effect of effusion volume was found on standard tympanometry. CONCLUSIONS Wideband acoustic immittance, and more specifically, absorbance, is a strong and sensitive indicator of the volume of a middle ear effusion in children with otitis media with effusion.

Abstract
OBJECTIVE Recent literature has highlighted a link between hearing loss as a result of otitis media in the early years of life and impacted binaural processing skills in later childhood. Such findings are of particular relevance to Indigenous Australian children, who tend to experience otitis media earlier in life and for longer periods than their non-Indigenous counterparts. There is also growing interest in the effects of reduced auditory processing ability on a child's early learning of language and, specifically, on phonological awareness that contributes to word reading skills. The aim of the present study was to determine the association between hearing thresholds, dichotic listening skills and phonological awareness in children with pervasive otitis media (OM) from remote Indigenous communities of Australia who generally do not speak English as a first language. METHODS Participants included one hundred and one children between the ages of 4.8-7.9 years (mean 6.1 years) from three separate remote Northern Territory communities. Evaluations included otoscopy, air conduction PTA, and tympanometry. All children were also assessed on the Dichotic Digits difference test (DDdT) and the Foundations of Early Literacy Assessment (FELA), assessing children's dichotic listening and phonological awareness respectively. RESULTS The results showed that 56% of the children had middle ear dysfunctions (type B and type C on tympanometry results) in at least one ear on the day. Partial correlation showed a significant correlation, between dichotic scores and FELA with age as covariate (r = 0.45, p < 0.001). One way ANOVA showed females exhibited a significantly higher performance compared to males on FELA [F (1, 99) = 5.47, p = 0.021]. The overall regression model was found to be significant in predicting total FELA scores [F (7, 77) = 7.56, p < 0.0005]. Age and gender as well as dichotic listening scores explain 40.7% of the variance. CONCLUSIONS The results reinforce the importance of managing the ear health of Indigenous children, clarifying the impact this has on listening and phonological awareness. These findings highlight the importance of evaluating children's listening abilities, and how poor listening can impact phonological awareness. The findings have important implications for ensuring optimal listening and learning conditions in schools in remote NT communities.

Abstract
OBJECTIVE To investigate and compare babbling, early consonant production and proficiency from 10 to 36 months of age and its relationship with hearing in children with otitis media with effusion (OME) with or without cleft palate. DESIGN Prospective, longitudinal group comparison study. SETTING University hospital. PARTICIPANTS Fifteen children born with nonsyndromic cleft palate with or without cleft lip (CP±L) and 15 age-matched children with hearing loss (HL) associated with OME but without cleft palate (noncleft group). MAIN OUTCOME MEASURES Canonical babbling (CB) and early consonant variables (presence of oral stops, anterior stops, dental/alveolar stops, number of different true consonants) at 10 and 18 months, and percentage of consonants correct proficiency (PCC) at 36 months. RESULTS A total of 54% of the CP±L group and 77% of the noncleft group had CB. The noncleft group had a significantly higher prevalence of all consonant variables. Percentage of consonants correct was 61.9% in the CP±L group and 81.6% in the noncleft group. All early consonant variables except CB were significantly related to PCC. Hearing sensitivity at 18 and 30 months correlated with PCC and explained 40% of the variation. CONCLUSIONS Mild HL impacted presence of CB at 10 months and was related to consonant proficiency at 36 months in children with HL associated with OME and children with cleft palate. The noncleft group showed results at 36 months similar to children with normal hearing; however, the CP±L group did not. Although the cleft palate may have a bigger impact on the speech development, management of hearing sensitivity would also be beneficial.

Abstract
OBJECTIVES Congenital cytomegalovirus (cCMV) infection is the leading cause of nonhereditary sensorineural hearing loss in childhood and is also associated with CNS abnormalities. The main objective is to investigate the prognostic value of neonatal cranial ultrasound (cUS) and cranial magnetic resonance imaging (cMRI) in predicting long-term hearing outcome in a large cohort of cCMV-infected symptomatic and asymptomatic patients. DESIGN Data were prospectively collected from a multicentre Flemish registry of children with cCMV infection born between 2007 and 2016. Neonatal cUS and cMRI scans were examined for lesions related to cCMV infection. Audiometric results at different time points were analyzed. The imaging and audiometric results were linked and diagnostic values of cUS and cMRI were calculated for the different hearing outcomes. RESULTS We were able to include 411 cCMV patients, of whom 40% was considered symptomatic at birth. Cranial ultrasound abnormalities associated with cCMV infection were found in 76 children (22.2% of the cUS scans), whereas cMRI revealed abnormalities in 74 patients (26.9% of the cMRI scans). A significant relation could be found between the presence of cUS or cMRI abnormalities and hearing loss at baseline and last follow-up. Cranial ultrasound and cMRI findings were not significantly correlated with the development of delayed-onset hearing loss. Specificity and sensitivity of an abnormal cUS to predict hearing loss at final follow-up were 84% and 43%, respectively compared with 78% and 39% for cMRI. Normal cUS and cMRI findings have a negative predictive value of 91% and 92%, respectively, for the development of delayed-onset hearing loss. CONCLUSIONS Neuroimaging evidence of CNS involvement in the neonatal period is associated with the presence of hearing loss in children with a cCMV infection. Imaging abnormalities are not predictive for the development of delayed-onset hearing loss.

Abstract
OBJECTIVE The aim of this study was to explore the impact of otitis media on auditory evoked potentials in children with a history of otitis media in comparison to a control group. DESIGN 90 children, with normal hearing and middle ear status at time of assessment, aged between 8 and 14 years (44 boys and 46 girls) were enrolled in this study. 50 children (28 boys and 22 girls) had a documented history of Otitis Media. The control group consisted of 40 children (17 boys and 23 girls) with no documented history of otitis media. All children completed the auditory evoked potentials tasks of Auditory Brainstem Response (ABR) and P300. RESULTS Auditory Evoked Potentials results demonstrated significantly increased latencies and decreased amplitudes in the otitis media group. ABR showed significantly latency delay of waves III and V by 0.1 msec (p < 0.001) and reduced amplitude (0.06 μV, p = 0.002 and 0.05 μV, p = 0.008, respectively) in the otitis media group compared to control group. P300 also showed significant latency delays (13,41 ms, p = 0.008) in otitis media group. No significant difference was seen for amplitude between CG and otitis media group for P300. CONCLUSION The results demonstrate the negative effects of otitis media on auditory evoked potentials in children with a history of middle ear disease as can be seen by changes on the ABR and P300 measures.

Abstract
OBJECTIVES To explore the rule of extended high-frequency (EHF) audiometry recovery in patients with acute otitis media. METHODS From January 2016 to July 2019, patients with acute otitis media in the outpatient department of otology were studied. The diagnosis was made according to the otoscopy and acoustic impedance tests, and antibiotics and other treatment programs were given. The patients were followed up to compare the effects of different recovery time on extended high-frequency audiometry in patients with acute otitis media. RESULTS 146 patients with acute otitis media (69 in the left ear and 77 in the right ear) were selected for observation and follow-up. The patients were divided into three groups according to the time from the onset to the disappearance of hyperacusis and earache symptoms: ≤ 5 days group (26 patients, 17.8%), 6-10 days group (74 patients, 50.7%), and > 10 days group (46 patients, 31.5%). The threshold of EHF in the study group was significantly higher than that in the control group in the early stage. According to the study design for follow-up, we found that with the prolongation of the duration of acute otitis media, the extended high frequency of different groups had different changes. CONCLUSIONS Our results show that the recovery time of EHF in patients with acute otitis media was later than that of the standard audiogram and was closely related to the course of the disease. This is of great significance for discovering the hidden hearing loss of the patients and taking the treatment plan as soon as possible.

Abstract
OBJECTIVES The use of cone-beam computed tomography (CBCT) is well-established in clinical practice. This study seeks to categorize and quantify the incidental finding (IF) rate on CBCT in patients with cleft lip and palate (CLP) prior to orthodontic or surgical treatment. METHODS This is systematic retrospective review of head and neck CBCTs in patients with nonsyndromic CLP taken between 2012 and 2019 at a single tertiary referral center. All assessments were performed independently by 4 observers (a head and neck radiologist and 3 orthodontists, including 2 fellowship-trained cleft-craniofacial orthodontists ). The images were divided into 9 anatomical areas and screened using serial axial slices and 3D reconstructions. The absolute number of IFs was reported for each area and statistical analysis was performed. RESULTS Incidental findings were found in 106 (95.5%) of the 111 patients. The most common sites were the maxilla (87.4%, principally dental anomalies), paranasal sinuses (46.8%, principally inflammatory opacification), and inner ear cavities (18.9%, principally inflammatory opacification). Eleven patients had skull malformations. Thirty-three patients had IFs in 1 anatomical area, 49 patients in 2 anatomical areas, 19 patients in 3 areas, and 5 patients presented with IFs in 4 of the 9 anatomical areas. DISCUSSION In patients with CLP, IFs on CBCT exam were present in the majority of cases. Most patients with IFs had them in multiple anatomical areas of the head and neck. The maxillary dental-alveolar complex was the most common area. Inflammatory changes in the inner ear cavities and paranasal sinuses were also common; however, cervical spine and skull abnormalities were also identified. Clinicians caring for patients with CLP should be aware of IFs, which may warrant further investigation and treatment.

Abstract
Different guidelines are adopted in clinics and countries to assess pure tone hearing sensitivity in children with otitis media with effusion (OME). Some guidelines specify a broad range of audiometric frequencies that must be tested and from which average thresholds determined, while others leave test frequencies unspecified. For guidelines that suggest specific frequencies there are various pure tone frequencies and frequency ranges given. The present study investigated whether (1) a full range of audiometric frequencies is required to evaluate hearing loss caused by OME in children, or if neighboring frequencies provide essentially the same threshold information, and (2) if different combinations of test frequency pure tone averaging calculations may affect decision criteria for surgical treatment. In a retrospective cohort study, right and left ear air conduction pure tone threshold data were obtained, from 125 Hz to 8 kHz, for 96 children with OME aged 4 to 12 years. Paired t-tests, correlation tests (Pearson’s r, Cronbach’s alpha, intraclass correlation) and absolute differences were used to examine the relationships among pure tone audiometric (PTA) frequencies for all ears with hearing loss. 168 ears were found to have OME-related hearing loss. Only the 125 Hz—250 Hz comparison showed no statistically significant difference between neighboring thresholds. However, only the 4 kHz and 8 kHz comparison showed a clinically significant mean difference of ≥ 10 dB. When viewing individual differences, comparison between 250 Hz and 500 Hz, 125 Hz and 500 Hz, and 4 kHz and 8 kHz, showed a large number of ears with clinically significant differences between test frequencies. Comparisons among low frequency 3 PTA average (500 Hz, 1 kHz, 2 kHz), high frequency 3 PTA average (1 kHz, 2 kHz, 4 kHz), and 4 frequency PTA average (500 Hz, 1 kHz, 2 kHz, 4 kHz) showed no statistically significant differences, with very strong correlations for all comparisons. In addition, for all the combinations of PTA averages, no clinically significant differences were found for the various comparisons or among individual results. Clinically, testing hearing sensitivity in the 125 Hz to 8 kHz range is worthwhile in evaluating hearing sensitivity in children with OME due to large individual variability across audiometric frequencies. However, frequencies tested for criterion averages for surgical treatments of children with OME may be restricted to 3 frequency PTA averages, either an average of 500 Hz, 1 kHz, 2 kHz or an average of 1 kHz, 2 kHz, 4 kHz, as no clinically significant differences were found using these or a 4 frequency averaging technique. For research purposes, 250 Hz can proxy for hearing thresholds at 125 Hz; and the low frequency 3 PTA average, high frequency 3 PTA average and 4 frequency PTA average may be used interchangeably, as no statistically significant differences were found among these measures.

Abstract
Accurate sound localization requires normal binaural input and precise auditory neuronal representation of sound spatial locations. Previous studies showed that unilateral hearing loss profoundly impaired the sound localization abilities. However, the underlying neural mechanism is not fully understood. Here, we investigated how chronic unilateral conductive hearing loss (UCHL) affected the neural tuning to sound source azimuth in the primary auditory cortex (AI). The UCHL was manipulated by the removal of tympanic membrane and malleus in the right ear of young (P14) rats and adult (P57) rats. We recorded the azimuth tuning of neurons in the left AI contralateral to the operated ear in the two groups of rats that experienced 2 months of UCHL, and in the left AI of age-matched control rats. We found that AI neurons in control rats showed predominant preference to sound from contralateral azimuths. However, UCHL weakened the cortical neuronal representation of contralateral azimuths on the operated ear side and strengthened the cortical neuronal representation of ipsilateral azimuths on the intact ear side. This effect was stronger in rats with UCHL at young age than in rats with UCHL in adulthood. Moreover, UCHL degraded the azimuth selectivity and azimuth sensitivity of AI neurons, and this effect was stronger in rats with UCHL in adulthood than in rats with UCHL at young age. These findings highlight a remarkable age-related experience-dependent plasticity of neural tuning to sound source azimuth in AI, and imply a neural mechanism for the impacts of chronic UCHL on sound localization abilities.

Abstract
The Société française d'ORL et de chirurgie cervico-faciale clinical practice guidelines concern the management of otitis media with effusion (OME) in children under the age of 12 years. They are based on extensive review of MEDLINE and Cochrane Library publications in English or French from 1996 to 2016 concerning the methods of diagnosis and assessment of otitis media with effusion, as well as the efficacy of tympanostomy tubes and medical and surgical treatments of OME.

Abstract
OBJECTIVES To evaluate the relation between ventilation tube insertion, otitis media with effusion duration and otologic outcomes in unilateral cleft lip and/or cleft palate children from infancy to teenage age. DESIGN AND POPULATION Retrospective longitudinal charts review of patients from the multidisciplinary cleft team of the University Hospital of Lausanne over a 30-year period. 146 charts from consecutive patients with non-syndromic unilateral cleft lip and/or cleft palate who were born between January 1986 and January 2003 were included. RESULTS The earlier in life a cleft child experience his first otitis media with effusion (OME), the worse his long-term hearing will be. Along with the age of onset of OME, we disclosed an influence of the duration of OME without ventilation tube (VT) insertion on short and long-term hearing outcomes. Different patterns were observed between cleft palate (CP) and cleft lip palate children (CLP), with a higher incidence of otitis media with effusion for the CLP group than the CP group. Direct positive relationship between VT insertion and hearing were disclosed and evaluation of long-term complications did not reveal significant relation with VT insertion. Of note, OME in CLP children led to a higher rate (but not statistically significant) of chronic ear complications than in the CP group, that may indicate more persistent OME or different adverse effect on the middle ear mucosa between CP and CLP children. CONCLUSIONS Individualized counseling should take into account different factors such as the type of cleft, the age of onset of OME and duration of OME, keeping in mind the adverse effect of persistent middle ear fluid. In the present report, results prone an early ventilation tube insertion to prevent short and long-term injury to the middle ear homeostasis, hearing loss and related issues.

Abstract
Otitis media with effusion (OME) is considered a form of relative sensory deprivation that often occurs during a critical period of language acquisition in children. Animal studies have demonstrated that hearing loss during early development can impair behavioral sensitivity to amplitude modulation (AM), critical for speech understanding, even after restoration of normal hearing thresholds. AM detection in humans with a history of OME-associated conductive hearing loss (CHL) has not been previously investigated. Our objective was to determine whether OME-associated CHL in children ages 6 months to 3 years results in deficits in AM detection in later childhood, after restoration of normal audiometric thresholds. Children ages 4 to 7 years with and without a history of OME-associated CHL participated in an AM detection two-alternative forced-choice task at 8 and 64 Hz modulation frequencies using a noise carrier signal and an interactive touch screen interface. Thirty-four subjects were studied (17 with a history of OME-related CHL and 17 without). Modulation detection thresholds improved with age and were slightly lower (more sensitive) for the 64 Hz modulation frequency for both groups. Modulation detection thresholds of children with a history of OME-associated CHL were higher than control thresholds at 5 years, but corrected to expected levels between ages 6-7. OME-associated CHL results in impaired AM detection, even when measured years after restoration of normal audiometric thresholds. Future studies may shed light on implications for speech and language development and academic success for children affected by OME and associated conductive hearing loss.

Abstract
AbstractBackgroundHearing loss can present at birth or be acquired as a result of illness, middle-ear disease, injury, age, overuse of certain medications, and/or induced by exposure to damaging noise levels. There are serious short-term consequences for people living with hearing impairment, including the effects on language acquisition, education, employment and overall wellbeing. There are also complex long-term implications.ObjectivesThis review aimed to present some of the leading causes of ear disease and hearing loss globally, and to identify their impact at both an individual and societal level.

Abstract
Sensory deprivation during development induces lifelong changes to central nervous system function that are associated with perceptual impairments. However, the relationship between neural and behavioral deficits is uncertain due to a lack of simultaneous measurements during task performance. Therefore, we telemetrically recorded from auditory cortex neurons in gerbils reared with developmental conductive hearing loss as they performed an auditory task in which rapid fluctuations in amplitude are detected. These data were compared to a measure of auditory brainstem temporal processing from each animal. We found that developmental HL diminished behavioral performance, but did not alter brainstem temporal processing. However, the simultaneous assessment of neural and behavioral processing revealed that perceptual deficits were associated with a degraded cortical population code that could be explained by greater trial-to-trial response variability. Our findings suggest that the perceptual limitations that attend early hearing loss are best explained by an encoding deficit in auditory cortex.

Abstract
It has been demonstrated that sensory deprivation results in homeostatic adjustments recovering neuronal activity of the deprived cortex. For example, deprived vision multiplicatively scales up mEPSC amplitudes in the primary visual cortex, commonly referred to as synaptic scaling. However, whether synaptic scaling also occurs in auditory cortex after auditory deprivation remains elusive. Using periodic intrinsic optical imaging in adult mice, we show that conductive hearing loss (CHL), initially led to a reduction of primary auditory cortex (A1) responsiveness to sounds. However, this was followed by a complete recovery of A1 activity evoked sounds above the threshold for bone conduction, 3 days after CHL. Over the same time course patch-clamp experiments in slices revealed that mEPSC amplitudes in A1 layers 2/3 pyramids scaled up multiplicatively in CHL mice. No recovery of sensory evoked A1 activation was evident in TNFα KO animals, which lack synaptic scaling. Additionally, we could show that the suppressive effect of sounds on visually evoked visual cortex activity completely recovered along with TNFα dependent A1 homeostasis in WT animals. This is the first demonstration of homeostatic multiplicative synaptic scaling in the adult A1. These findings suggest that mild hearing loss massively affects auditory processing in adult A1.

Abstract
Otitis Media with Effusion (OME) is an inflammatory condition of the middle ear cleft, acute or chronic, with collection of fluid in the middle ear with an intact tympanic membrane. It is a very common disease in childhood, the most frequent cause of hearing loss in childhood and often requiring surgery. OME is called chronic when the fluid in the middle ear persists for more than three months or when the episodes recur six or more times in one year. The current article covers various aspects of OME including definition, epidemiology. Pathomechanisms, risk factors, role of allergy in OME, impact of upper airway disease on OME, eosinophilic otitis media and management of OME.

Abstract
Auditory activity plays an important role in the development of the auditory system. Decreased activity can result from conductive hearing loss (CHL) associated with otitis media, which may lead to long-term perceptual deficits. The effects of CHL have been mainly studied at later stages of the auditory pathway, but early stages remain less examined. However, changes in early stages could be important because they would affect how information about sounds is conveyed to higher-order areas for further processing and localization. We examined the effects of CHL at auditory nerve synapses onto bushy cells in the mouse anteroventral cochlear nucleus following occlusion of the ear canal. These synapses, called endbulbs of Held, normally show strong depression in voltage-clamp recordings in brain slices. After 1 week of CHL, endbulbs showed even greater depression, reflecting higher release probability. We observed no differences in quantal size between control and occluded mice. We confirmed these observations using mean-variance analysis and the integration method, which also revealed that the number of release sites decreased after occlusion. Consistent with this, synaptic puncta immunopositive for VGLUT1 decreased in area after occlusion. The level of depression and number of release sites both showed recovery after returning to normal conditions. Finally, bushy cells fired fewer action potentials in response to evoked synaptic activity after occlusion, likely because of increased depression and decreased input resistance. These effects appear to reflect a homeostatic, adaptive response of auditory nerve synapses to reduced activity. These effects may have important implications for perceptual changes following CHL. SIGNIFICANCE STATEMENT Normal hearing is important to everyday life, but abnormal auditory experience during development can lead to processing disorders. For example, otitis media reduces sound to the ear, which can cause long-lasting deficits in language skills and verbal production, but the location of the problem is unknown. Here, we show that occluding the ear causes synapses at the very first stage of the auditory pathway to modify their properties, by decreasing in size and increasing the likelihood of releasing neurotransmitter. This causes synapses to deplete faster, which reduces fidelity at central targets of the auditory nerve, which could affect perception. Temporary hearing loss could cause similar changes at later stages of the auditory pathway, which could contribute to disorders in behavior.

Abstract
The clinical practice guideline on otitis media with effusion (OME) provides evidence-based recommendations on diagnosing and managing OME in children. This is an update of the 1994 clinical practice guideline “Otitis Media With Effusion in Young Children,” which was developed by the Agency for Healthcare Policy and Research (now the Agency for Healthcare Research and Quality). In contrast to the earlier guideline, which was limited to children aged 1 to 3 years with no craniofacial or neurologic abnormalities or sensory deficits, the updated guideline applies to children aged 2 months through 12 years with or without developmental disabilities or underlying conditions that predispose to OME and its sequelae. The American Academy of Pediatrics, American Academy of Family Physicians, and American Academy of Otolaryngology- Head and Neck Surgery selected a subcommittee composed of experts in the fields of primary care, otolaryngology, infectious diseases, epidemiology, hearing, speech and language, and advanced practice nursing to revise the OME guideline. The subcommittee made a strong recommendation that clinicians use pneumatic otoscopy as the primary diagnostic method and distinguish OME from acute otitis media (AOM). The subcommittee made recommendations that clinicians should (1) document the laterality, duration of effusion, and presence and severity of associated symptoms at each assessment of the child with OME; (2) distinguish the child with OME who is at risk for speech, language, or learning problems from other children with OME and more promptly evaluate hearing, speech, language, and need for intervention in children at risk; and (3) manage the child with OME who is not at risk with watchful waiting for 3 months from the date of effusion onset (if known), or from the date of diagnosis (if onset is unknown). The subcommittee also made recommendations that (4) hearing testing be conducted when OME persists for 3 months or longer, or at any time that language delay, learning problems, or a significant hearing loss is suspected in a child with OME; (5) children with persistent OME who are not at risk should be reexamined at 3- to 6-month intervals until the effusion is no longer present, significant hearing loss is identified, or structural abnormalities of the eardrum or middle ear are suspected; and (6) when a child becomes a surgical candidate, tympanostomy tube insertion is the preferred initial procedure. Adenoidectomy should not be performed unless a distinct indication exists (nasal obstruction, chronic adenoiditis); repeat surgery consists of adenoidectomy plus myringotomy, with or without tube insertion. Tonsillectomy alone or myringotomy alone should not be used to treat OME. The subcommittee made negative recommendations that (1) population-based screening programs for OME not be performed in healthy, asymptomatic children and (2) antihistamines and decongestants are ineffective for OME and should not be used for treatment; antimicrobials and corticosteroids do not have long-term efficacy and should not be used for routine management. The subcommittee gave as options that (1) tympanometry can be used to confirm the diagnosis of OME and (2) when children with OME are referred by the primary clinician for evaluation by an otolaryngologist, audiologist, or speech-language pathologist, the referring clinician should document the effusion duration and specific reason for referral (evaluation, surgery), and provide additional relevant information such as history of AOM and developmental status of the child. The subcommittee made no recommendations for (1) complementary and alternative medicine as a treatment for OME based on a lack of scientific evidence documenting efficacy and (2) allergy management as a treatment for OME based on insufficient evidence of therapeutic efficacy or a causal relationship between allergy and OME. Last, the panel compiled a list of research needs based on limitations of the evidence reviewed. The purpose of this guideline is to inform clinicians of evidence-based methods to identify, monitor, and manage OME in children aged 2 months through 12 years. The guideline may not apply to children older than 12 years because OME is uncommon and the natural history is likely to differ from younger children who experience rapid developmental change. The target population includes children with or without developmental disabilities or underlying conditions that predispose to OME and its sequelae. The guideline is intended for use by providers of health care to children, including primary care and specialist physicians, nurses and nurse practitioners, physician assistants, audiologists, speech-language pathologists, and child development specialists. The guideline is applicable to any setting in which children with OME would be identified, monitored, or managed. This guideline is not intended as a sole source of guidance in evaluating children with OME. Rather, it is designed to assist primary care and other clinicians by providing an evidence-based framework for decision-making strategies. It is not intended to replace clinical judgment or establish a protocol for all children with this condition, and may not provide the only appropriate approach to diagnosing and managing this problem.

Tympanometric Findings among Children with Adenoid Hypertrophy in Port Harcourt, Nigeria. Int J Otolaryngol 2016; 2016:1276543. [PMID: 27563311 PMCID: PMC4985572 DOI: 10.1155/2016/1276543] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2016] [Accepted: 07/05/2016] [Indexed: 11/17/2022] Open
Abstract
Introduction. Adenoid hypertrophy (AH) is a common childhood disorder. Adenoid plays a significant role in the pathogenesis of otitis media with effusion (OME). The aim of this study is to critically appraise the tympanometric finding among children with adenoid hypertrophy in Port Harcourt, Nigeria. Methodology. A Prospective, controlled study carried out among newly diagnosed cases of adenoid hypertrophy at the ENT clinic of the UPTH, between November 2014 and June 2015. Tympanometry was done on each child and each ear was considerably studied as a single entity. Types B and C tympanograms were used as indicators of OME. Data was collected and analyzed using SPSS version 20. Results. Sixty-eight cases of adenoid hypertrophy were seen within the study period and 136 ears were studied. Forty (29.4%) ears had type B tympanogram, while 36 (26.5%) ears had type C. The incidence of OME was 55.9%; there were 12 (17.6%) unilateral OME, while bilateral OME was 32 (47.1%). Grade 3 AH was prevalent and was statistically significant with the OME. Conclusion. This study had shown adenoidal hypertrophy as a significant risk factor for OME in children. There was more bilateral OME than unilateral. The more severe grade of AH was more prevalent and it was shown to be statistically significant with OME, thus being a significant risk factor for OME in children. This establishes the need for prompt hearing evaluation and management.

Hearing in Children with Congenital Cytomegalovirus Infection: Results of a Longitudinal Study. J Pediatr 2016; 172:110-115.e2. [PMID: 26858192 DOI: 10.1016/j.jpeds.2016.01.024] [Citation(s) in RCA: 69] [Impact Index Per Article: 8.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/15/2015] [Revised: 11/23/2015] [Accepted: 01/07/2016] [Indexed: 11/19/2022]
Abstract
OBJECTIVES To evaluate hearing outcome, to characterize the nature of symptomatic and asymptomatic congenital cytomegalovirus (cCMV) infection and associated hearing loss, and to compare results with data from previous studies. STUDY DESIGN A prospective multicenter registry was set up in 2007. Six centers participated in the development of a standardized protocol for diagnosis, treatment, and follow-up. Data were gathered in an online registry. Children (n = 379) with a documented cCMV infection and at least 2 separate audiologic evaluations were included. Audiometric results from a multicenter cohort study of children with cCMV infection with longitudinal observation were examined. RESULTS Results from 123 children with a symptomatic and 256 children with an asymptomatic cCMV infection were analyzed. In the group with symptomatic cCMV, 63% had hearing loss, compared with 8% in the group with asymptomatic cCMV. Delayed-onset hearing loss occurred in 10.6% of symptomatic cCMV and in 7.8% of asymptomatic cCMV. In the group with symptomatic cCMV, 29.3% of children used some kind of hearing amplification; 1.6% in the group with asymptomatic cCMV used hearing amplification. CONCLUSIONS Symptomatic and asymptomatic cCMV infections are a major cause of hearing loss in childhood. Reliable estimates of the long-term outcome of cCMV infection are mandatory to increase vigilance, especially among pregnant women and to draw attention to preventive measures, vaccine development, and prenatal and postnatal therapy. Universal screening of newborns for cCMV infection should be initiated and combined with longitudinal audiometric follow-up.

Abstract
OBJECTIVES The aim of this study was to investigate and compare auditory brainstem response (ABR) thresholds related to otitis media with effusion (OME) in infants with and without cleft palate and/or lip (CP±L). METHODS Forty-seven infants with CP±L and 67 infants with OME participated in the study. Hearing thresholds of ears of infants with OME were compared between groups and within the group with CP±L. RESULTS Infants with CP±L and OME presented with similar hearing thresholds as infants with OME and not CP±L. Within the cleft group, infants with isolated cleft palate and OME demonstrated significantly higher hearing thresholds than infants with unilateral cleft lip and palate and OME. CONCLUSION A high prevalence of infants with CP±L present with OME early in life. Hearing thresholds of these infants are similar to infants without CP±L, but with OME. The ear status and hearing thresholds of infants with CP±L needs to be monitored to be able to provide the best access to hearing in order to fully allow speech and language development.

Abstract
PURPOSE To study the temporal auditory ordering and resolution abilities in children with and without a history of early OME and ROME, as well as to study the responses according to age. METHODS A total of 59 children were evaluated, and all of them presented pure tone thresholds within the normal range at the time of the conduction of the hearing tests. The children were divided into two groups according to the occurrence of episodes of recurrent otitis media. Then, each group was divided into two subgroups according to age: 7- and 8-year olds, and 9- and 10-year olds. All children were assessed with standard tests of temporal frequency (ordination) and gaps-in-noise (resolution). RESULTS For the temporal abilities studied, children with a history of otitis media presented significantly lower results compared to the control group. In the frequency pattern test, the correct answers increased with age in both groups. In the identification of silence intervals, the control group showed no change in threshold regarding to age, but this change was present in the group with a history of otitis media. CONCLUSION Episodes of otitis media with effusion in the first year of life, recurrent and persistent in preschool and school ages, negatively influence the temporal ordering and resolution abilities.

Abstract
BACKGROUND Breastfeeding is the reference against which alternative infant feeding models must be measured with regard to growth, development and other health outcomes. Although not a systematic review, this report provides an update for dental professionals, including an overview of general and oral health-related benefits associated with breastfeeding. TYPES OF STUDIES REVIEWED The authors examined the literature regarding general health protections that breastfeeding confers to infants and mothers and explored associations between breastfeeding, occlusion in the primary dentition and early childhood caries. To accomplish these goals, they reviewed systematic reviews when available and supplemented them with comparative studies and with statements and reports from major nongovernmental and governmental organizations. RESULTS When compared with health outcomes among formula-fed children, the health advantages associated with breastfeeding include a lower risk of acute otitis media, gastroenteritis and diarrhea, severe lower respiratory infections, asthma, sudden infant death syndrome, obesity and other childhood diseases and conditions. Evidence also suggests that breastfed children may develop a more favorable occlusion in the primary dentition. The results of a systematic review in which researchers examined the relationship between breastfeeding and early childhood caries were inconclusive. CONCLUSIONS AND CLINICAL IMPLICATIONS The American Academy of Pediatric Dentistry, Chicago, suggests that parents gently clean infants' gums and teeth after breastfeeding. The American Academy of Pediatrics, Elk Grove Village, Ill., recommends that breastfeeding should be exclusive for about the first six months of life and should continue, with the introduction of appropriate complementary foods, to at least age 12 months or beyond, as desired by mother and child. Dentists and staff members can take steps to ensure they are familiar with the evidence and guidelines pertaining to breastfeeding and to oral health. They are encouraged to follow the surgeon general's recommendations to promote and support optimal breastfeeding and oral health practices among their patients.

[PMID: 24409125 PMCID: PMC3873525 DOI: 10.3389/fnsys.2013.00123] [Citation(s) in RCA: 59] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2013] [Accepted: 12/12/2013] [Indexed: 11/23/2022] Open
Abstract
Under normal hearing conditions, comparisons of the sounds reaching each ear are critical for accurate sound localization. Asymmetric hearing loss should therefore degrade spatial hearing and has become an important experimental tool for probing the plasticity of the auditory system, both during development and adulthood. In clinical populations, hearing loss affecting one ear more than the other is commonly associated with otitis media with effusion, a disorder experienced by approximately 80% of children before the age of two. Asymmetric hearing may also arise in other clinical situations, such as after unilateral cochlear implantation. Here, we consider the role played by spatial cue integration in sound localization under normal acoustical conditions. We then review evidence for adaptive changes in spatial hearing following a developmental hearing loss in one ear, and show that adaptation may be achieved either by learning a new relationship between the altered cues and directions in space or by changing the way different cues are integrated in the brain. We next consider developmental plasticity as a source of vulnerability, describing maladaptive effects of asymmetric hearing loss that persist even when normal hearing is provided. We also examine the extent to which the consequences of asymmetric hearing loss depend upon its timing and duration. Although much of the experimental literature has focused on the effects of a stable unilateral hearing loss, some of the most common hearing impairments experienced by children tend to fluctuate over time. We therefore propose that there is a need to bridge this gap by investigating the effects of recurring hearing loss during development, and outline recent steps in this direction. We conclude by arguing that this work points toward a more nuanced view of developmental plasticity, in which plasticity may be selectively expressed in response to specific sensory contexts, and consider the clinical implications of this.

Abstract
Auditory cortical maps have been a long-standing focus of studies that assess the expression, mechanisms, and consequences of sensory plasticity. Here we discuss recent progress in understanding how auditory experience transforms spatially organized sound representations at higher levels of the central auditory pathways. New insights into the mechanisms underlying map changes have been achieved and more refined interpretations of various map plasticity effects and their consequences in terms of behavioral corollaries and learning as well as other cognitive aspects have been offered. The systematic organizational principles of cortical sound processing remain a key aspect in studying and interpreting the role of plasticity in hearing.

Abstract
OBJECTIVE Children with a Cleft Palate (CLP) and with or without cleft lips (non-syndromic) universally present with Secretory Otitis Media (SOM). The purpose of this study was to determine the incidence of secretory otitis media that occurs in patients with cleft palates and to confirm the existence of these manifestations by doing a Basic Audiologic Evaluation (BAE). MATERIAL AND METHODS A retrospective study was done on forty four male and female children who were within the 2 to 14 years age range, with non-syndromic cleft palates with or without cleft lips, with the symptoms of SOM. Otoscopy examinations were done in all the cases. X-rays of the mastoids (both sides) were done in all the cases to detect the pneumatization of the mastoid air cell system. The Basic Audiologic Evaluation (BAE) includes an evaluation by tympanometry of the middle ear function and an evaluation by pure tone audiometry to establish the type of hearing loss. RESULTS A majority of the patients (47.27%) were in the age group of eight-to-fourteen (8-14) years. The Basic Audiologic Evaluation (BAE) revealed that 77.27% of the children had presented with normal hearing; 13.6% had conductive hearing loss and 2.2% had presented with a mixed hearing loss. We noticed that 68.2% of the children had type A curves; 21.2% of the children had type C tympanometry curves; 7.1% had type B curves and 3.5% had Ad curves. The contralateral acoustic reflex was present in 54.5% of the children and 45.5% did not have this reflex. A majority of the patients (46%) showed sclerotic changes in their mastoid air cell systems in the X-rays of the mastoids. CONCLUSION The significantly higher prevalence of SOM in the children with cleft was confirmed by the study. Also, the hearing loss which was associated with SOM was evident and it demonstrated that there was a high prevalence of a mild conductive hearing loss when SOM was present. The cleft palate contributed to the occurrence of the secretory otitis media and it required proper ENT and audiological follow ups.

Abstract
Early binaural experience can recalibrate central auditory circuits that support spatial hearing. However, it is not known how binaural integration matures shortly after hearing onset or whether various developmental stages are differentially impacted by disruptions of normal binaural experience. Here we induce a brief, reversible unilateral conductive hearing loss (CHL) at several experimentally determined milestones in mouse primary auditory cortex (A1) development and characterize its effects ~1 week after normal hearing is restored. We find that CHL shapes A1 binaural selectivity during two early critical periods. CHL before P16 disrupts the normal coregistration of interaural frequency tuning, whereas CHL on P16, but not before or after, disrupts interaural level difference sensitivity contained in long-latency spikes. These data highlight an evolving plasticity in the developing auditory cortex that may relate to the aetiology of amblyaudia, a binaural hearing impairment associated with bouts of otitis media during human infancy.

Abstract
OBJECTIVE To investigate the prevalence and demographic, environmental and child associated risk factors of OME in schoolchildren in Eastern Anatolia, Turkey, and analyze the results with reference to the review of the literature. METHODS A total of 2355 children who were attending two different primary schools, one located in low, and the other located in a high socioeconomic district of city of Van were screened and 2320 children who met the inclusion criteria were enrolled to study. Standardized questionnaires that include nine questions for determination of risk factors were delivered to the parents to be filled before examination of each child. All of the children underwent both otoscopic examination and tympanometric evaluation to provide high accuracy on the diagnosis of OME. The association between children diagnosed as OME and the answers to the questionnaires were evaluated. Also, teachers of the children were asked to complete a questionnaire evaluating child's level of school success, and the success levels of children with or without OME were compared. RESULTS The prevalence of OME was found to be 10.43%. Second-hand smoking (p<0.0001), low socioeconomic status (p<0.001), living in a crowded house (p<0.001), presence of atopy (p<0.01), lack of breast-feeding (p<0.05), presence of URTI (p<0.0001), young age (p<0.001) and snoring (p<0.0001) were found to be associated with prevalence of OME. No significance was found for duration of breast-feeding, gender, birth history and previous otolaryngological operations. Also, children with OME were tended to be less successful in terms of school success. CONCLUSIONS The potential of OME to cause serious sequelae and complications that may affect children's life long-term, makes the disease an important health problem. Environmental, epidemiologic and familial factors play an important role in pathogenesis of OME. Caretakers must be informed about these highly modifiable risk factors, by this way the development or delayed diagnosis of the disease that may cause serious consequences can be prevented.

Abstract
Studies relating chronic otitis media and language disorders in children have not reported consistent findings. We carried out the first selective study aimed at discerning the role of chronic right otitis media in children less than 3 years of age in language development. A total of 35 children were studied using a full linguistic protocol, auditory brainstem responses, and middle latency responses. Twelve children had a history of chronic exclusive right otitis media. Seventeen age-matched children were selected as controls. Also, three children having a history of chronic left otitis media were compared with three age-matched controls. Linguistic tests showed significant differences between patients and controls in phonetic, phonological, and syntax scores but not semantics. Correlation studies between linguistic scores and auditory evoked responses in the whole cohort showed a significant coefficient in phonetic and phonological domains. These results emphasize the causative effect of right ear chronic otitis media and indicate that it mainly impairs phonetic and phonological coding of sounds, which may have implications for prophylactic treatment of at-risk children.
