Assessment and Management of Hearing Loss in Children with Cleft Lip and/or Palate: a Review

Central Auditory Processing Abilities in Children with Non-Syndromic Cleft Lip and Palate: An Electrophysiological Study

BACKGROUND

The present study compared the central auditory processing abilities using electrophysiological tests in children with non-syndromic cleft lip and palate (NSCLP) and their age-matched control group.

METHOD

Thirty children aged 7 to 15 years were recruited for the study. Participants were divided into 2 groups. The clinical group (children with NSCLP) comprised 15 children, while the control group (craniofacially typical peers) comprised 15 children with normal hearing sensitivity and auditory processing skills. Electrophysiological tests, including auditory brainstem responses (ABR), binaural interaction component (BIC) of ABR, auditory late latency responses (ALLR), and P300 were assessed.

RESULTS

The results showed deviant responses in ABR, BIC, and ALLR in children with NSCLP compared to craniofacially typical counterparts. However, no significant difference was observed in P300 between the two groups.

CONCLUSION

Children with NSCLP may be at a higher risk of central auditory processing disorder due to their abnormal neural transmission in the auditory nervous system. Also, assessing auditory processing abilities in children with NSCLP should include electrophysiological tests in the test battery for additional information regarding neural transmission.

Central Auditory Processing Abilities in Children with Non-Syndromic Cleft Lip/and Palate-a Behavioural Study

The present study aimed to assess the central auditory processing abilities and working memory in children with non-syndromic cleft lip and palate (NSCLP) and to compare with the developed normative and craniofacially normal peers. Sixteen NSCLP children aged 7 to 12 years and fifteen craniofacially normal peers were recruited in this study. Speech perception in noise Kannada (SPIN-K), gap detection threshold (GDT), dichotic consonant-vowel (DCV), and masking level difference (MLD) tests were administered to assess various central auditory processing abilities. Working memory abilities were assessed by using forward-digit span and backward-digit span tests. The results showed significant differences in SPIN-K, dichotic CV, GDT, forward digit, and backward digit span scores between children with NSCLP and craniofacially normal peers. Thus, it can be concluded from the present study that children with NSCLP have a risk of developing auditory processing deficits. To conclude, assessment of central auditory processing abilities in children with NSCLP is recommended.

Intellectual Functioning of Children With Isolated PRS, PRS-Plus, and Syndromic PRS

OBJECTIVE

Describe the intelligence quotient (IQ) of children with Pierre Robin sequence (PRS).

DESIGN

Prospective cohort study.

SETTING

Neurodevelopmental follow-up clinic within a hospital.

PATIENTS

Children with PRS (n = 45) who had been in the Neonatal Intensive Care Unit (NICU) were classified by a geneticist into 3 subgroups of isolated PRS (n = 20), PRS-plus additional medical features (n = 8), and syndromic PRS (n = 17) based on medical record review and genetic testing.

MAIN OUTCOME MEASURE

Children with PRS completed IQ testing at 5 or 8 years of age with the Wechsler Preschool and Primary Scale of Intelligence, Third Edition (WPPSI-III) or Fourth Edition (WPPSI-IV) or the Wechsler Intelligence Scale for Children, Fourth Edition (WISC-IV) or Fifth Edition (WISC-V).

RESULTS

IQ scores were more than 1 to 2 standard deviations below the mean for 36% of the overall sample, which was significantly greater compared to test norms (binomial test P = .001). There was a significant association between PRS subtype and IQ (Fisher's exact P = .026). While only 20% of children with isolated PRS were within 1 standard deviation below average and 35% of children with syndromic PRS were below 1 to 2 standard deviations, 75% of PRS-plus children scored lower than 1 to 2 standard deviations below the mean.

CONCLUSION

PRS subgroups can help identify children at risk for cognitive delay. The majority of children with PRS-plus had low intellectual functioning, in contrast to the third of children with syndromic PRS who had low IQ and the majority of children with isolated PRS who had average or higher IQ.

[Auditory processing in children and adolescents with cleft palate]

BACKGROUND

Patients with cleft palate often suffer from recurrent otitis media chronica with effusion during infancy. The consecutive binaural conductive hearing loss is seen as a risk factor for developing auditory processing disease. Since there are just a few studies examining auditory processing in this population this study aimed to investigate on an own patient cohort with different cleft manifestations in terms of auditory processing disorders in context to given studies.

MATERIAL AND METHODS

This study included 48 patients (5-16 years): all patients had a non-syndromic cleft palate and normal peripheral hearing at the time of examination. The protocol included otoscopy, pure tone audiogram, speech intelligibility in noise, dichotic speech discrimination, auditory short-term memory and a parental questionnaire.

RESULTS

The majority of the parents did not indicate problems in the parental questionnaire. 69 % of the participants showed conspicuous results in the speech intelligibility in noise, whereas the dichotic speech discrimination and the auditory short-term memory were suspicious in 16.7 % only. The results in both tests proved mainly a problem in younger children. Noticeable results in speech intelligibility in noise were found in all age groups.

CONCLUSION

Children and adolescents with cleft palate are at risk to develop auditory processing disorders. In this study population speech intelligibility in noise was the most common problem. 90 % of the children had received a speech therapy which could have already compensated problems concerning dichotic speech discrimination and the auditory short-term memory but not problems in speech intelligibility in noise.

Derecho a la atención sanitaria para madres y menores de 18 años afectados con labio y/o paladar hendido en República Dominicana

Objetivo: identificar y describir, desde la perspectiva del derecho fundamental a la salud, la garantía de la atención sanitaria en menores dominicanos afectados con labio y/o paladar hendido (LPH) y sus madres. Métodos: en tanto este es un estudio descriptivo, se realizaron encuestas semiestructuradas y se aplicó la observación no participante en los territorios de residencia de familias con menores afectados por LPH, atendidos en una fundación de República Dominicana. Resultados: la mayoría de familias afectadas por LPH pertenecen a clases sociales vulnerables con limitada capacidad de pago para adquirir seguros de salud. De las 39 familias abordadas, 26 madres no contaron con seguro de salud durante la gestación, pero los 39 pacientes con LPH sí contaban con algún tipo de aseguramiento. Se evidenció negación sistemática en la prestación de  servicios sanitarios, barreras administrativas, invisibilización de la problemática del LPH en los servicios de salud y en definitiva, un sistema de salud excluyente en la práctica. Conclusión: pese a que la atención sanitaria a gestantes y menores de 18 años se reconoce constitucionalmente como un derecho fundamental a cargo del Estado, la forma en que opera el sistema de salud dominicano supedita la atención a la capacidad de pago de las familias, lo que genera inequidades sociales y sanitarias que vulneran el goce efectivo del derecho a la salud de las madres y los menores que nacen con LPH. 

Behavioral Signs of (Central) Auditory Processing Disorder in Children with Nonsyndromic Cleft Lip and/or Palate: A Parental Questionnaire Approach

Objective

Children with nonsyndromic cleft lip and/or palate often have a high prevalence of middle ear dysfunction. However, there are also indications that they may have a higher prevalence of (central) auditory processing disorder. This study used Fisher's Auditory Problems Checklist for caregivers to determine whether children with nonsyndromic cleft lip and/or palate have potentially more auditory processing difficulties compared with craniofacially normal children.

Methods

Caregivers of 147 school-aged children with nonsyndromic cleft lip and/or palate were recruited for the study. This group was divided into three subgroups: cleft lip, cleft palate, and cleft lip and palate. Caregivers of 60 craniofacially normal children were recruited as a control group. Hearing health tests were conducted to evaluate peripheral hearing. Caregivers of children who passed this assessment battery completed Fisher's Auditory Problems Checklist, which contains 25 questions related to behaviors linked to (central) auditory processing disorder.

Result

Children with cleft palate showed the lowest scores on the Fisher's Auditory Problems Checklist questionnaire, consistent with a higher index of suspicion for (central) auditory processing disorder. There was a significant difference in the manifestation of (central) auditory processing disorder-linked behaviors between the cleft palate and the control groups. The most common behaviors reported in the nonsyndromic cleft lip and/or palate group were short attention span and reduced learning motivation, along with hearing difficulties in noise.

Conclusion

A higher occurrence of (central) auditory processing disorder-linked behaviors were found in children with nonsyndromic cleft lip and/or palate, particularly cleft palate. Auditory processing abilities should not be ignored in children with nonsyndromic cleft lip and/or palate, and it is necessary to consider assessment tests for (central) auditory processing disorder when an auditory diagnosis is made for this population.

Chinese children with nonsyndromic cleft lip/palate: Factors associated with hearing disorder

OBJECTIVES

This study examined the auditory status of Chinese children with nonsyndromic cleft lip/palate (NSCL/P), investigated factors associated with peripheral hearing loss and compared results with earlier studies in western countries.

METHODS

Case history profiles and audiological data from 148 Chinese children with NSCL/P, aged between 6 and 15 years, who attended the Cleft Lip and Palate Clinic Center in a major Chinese urban hospital from July 2012 to September 2013 were acquired. The audiological status of the participants was reviewed, based on the results of their pure tone audiometry, tympanometry and acoustic reflex thresholds assessments. Factors including age, gender, cleft type, residential locality and school achievement were examined in relation to auditory status.

RESULTS

Findings revealed that 17% of the Chinese children with NSCL/P had hearing impairment at the time of assessment. Unilateral hearing loss was noted in 12% of children and in 5% of cases bilateral hearing loss was noted. In the majority of cases the hearing loss was slight and conductive in nature. Age, gender, residential locality and school achievement were found to have no relationship with severity of hearing loss. Children with cleft lip showed a lower degree of hearing impairment than children with cleft palate or cleft lip and palate.

CONCLUSION

Similar to studies for western children, Chinese children with CL/P associated with no known syndrome are at risk of peripheral hearing loss, generally of conductive type. However, the prevalence of peripheral hearing loss appears to be less than in western children with NSCL/P. Ethnic/racial factors may be a major contributing factor accounting for the discrepancies between the current results and western studies.

Electrophysiological assessment of auditory processing disorder in children with non-syndromic cleft lip and/or palate

Objectives

Cleft lip and/or palate is a common congenital craniofacial malformation found worldwide. A frequently associated disorder is conductive hearing loss, and this disorder has been thoroughly investigated in children with non-syndromic cleft lip and/or palate (NSCL/P). However, analysis of auditory processing function is rarely reported for this population, although this issue should not be ignored since abnormal auditory cortical structures have been found in populations with cleft disorders. The present study utilized electrophysiological tests to assess the auditory status of a large group of children with NSCL/P, and investigated whether this group had less robust central auditory processing abilities compared to craniofacially normal children.

Methods

146 children with NSCL/P who had normal peripheral hearing thresholds, and 60 craniofacially normal children aged from 6 to 15 years, were recruited. Electrophysiological tests, including auditory brainstem response (ABR), P1-N1-P2 complex, and P300 component recording, were conducted.

Results

ABR and N1 wave latencies were significantly prolonged in children with NSCL/P. An atypical developmental trend was found for long latency potentials in children with cleft compared to control group children. Children with unilateral cleft lip and palate showed a greater level of abnormal results compared with other cleft subgroups, whereas the cleft lip subgroup had the most robust responses for all tests.

Conclusion

Children with NSCL/P may have slower than normal neural transmission times between the peripheral auditory nerve and brainstem. Possible delayed development of myelination and synaptogenesis may also influence auditory processing function in this population. Present research outcomes were consistent with previous, smaller sample size, electrophysiological studies on infants and children with cleft lip/palate disorders. In view of the these findings, and reports of educational disadvantage associated with cleft disorders, further research that focuses on the auditory processing abilities of children with cleft lip/palate disorder is warranted.

Evaluation of an auditory assessment protocol for Chinese infants with nonsyndromic cleft lip and/or palate

OBJECTIVE

To objectively investigate the auditory status of mainland Chinese infants with nonsyndromic cleft lip and/or palate and to evaluate an auditory assessment protocol for this group.

DESIGN

Prospective cohort case review.

PATIENTS OR OTHER PARTICIPANTS

A total of 42 Chinese infants with nonsyndromic cleft lip and/or palate aged 6 to 24 months.

INTERVENTION

The hearing profiles of participants were acquired using otoscopy, tympanometry, transient-evoked otoacoustic emissions, and auditory brainstem response estimated hearing threshold. The efficiency of the current audiological test battery was analyzed also.

RESULTS

Sixty-four (64.2) percent of infants with nonsyndromic cleft lip and/or palate (55.9% of ears) were suspected to have middle ear disorder, and 85.7% of all subjects (83.3% of ears) were found to have hearing loss. Of those with confirmed loss, the overall mean auditory brainstem response estimated air-conduction hearing threshold was 53.5 ± 13.6 decibel normal hearing level [db nHL]. Using auditory brainstem response thresholds as a reference standard, the diagnostic agreement with the other assessment tools for normal/abnormal results was otoscopy, 69% (κ  =  .57); tympanometry, 66.7% (κ  =  .53); and transient-evoked otoacoustic emissions, 80% (κ  =  .64).

CONCLUSION

The high prevalence of middle ear disease and hearing loss in mainland Chinese infants with nonsyndromic cleft lip and/or palate in this study was in contrast to previous studies of older age groups of Chinese children conducted in Hong Kong and Singapore. The audiological assessment protocol used in our study could provide useful information; although, modifications may be necessary to ensure a complete diagnostic overview for children with craniofacial clefts.

Hearing outcomes in patients with cleft lip/palate

Objective : Children with cleft lip and palate or cleft palate only have a high incidence of conductive hearing loss from otitis media with effusion. Studies demonstrating longitudinal results are lacking. This study was undertaken to investigate long-term longitudinal hearing outcomes of children with cleft lip and/or cleft palate and cleft palate only. Design : Retrospective chart review. Setting : Clinical charts of patients born with cleft lip and palate or cleft palate only in 1985 to 1994 who were referred to the cleft team in Bergen, Norway. Study findings include 15 years of follow-up. Participants : The study population consisted of 317 children of whom 159 had nonsyndromic cleft lip and palate and 158 had nonsyndromic cleft palate. Main Outcome Measures : Pure tone average calculated from pure tone audiometry at ages 4, 6, and 15 years. Results : The median pure tone average significantly improved with increasing age. For the cleft lip and palate group, the median pure tone average at ages 4, 6, and 15 years was 16 dB hearing level (HL), 13 dB HL, and 9 dB HL, respectively (P ≤ .001). In the cleft palate group the median pure tone average at ages 4, 6, and 15 years was 15 dB HL, 12 dB HL, and 9 dB HL, respectively (P ≤ .001). There was no significant difference in the hearing levels between the two groups. Patients who had surgical closure of the palate at age 18 months had a significantly better pure tone average outcome at age 15 compared with patients who had surgery at 12 months. Conclusions : Hearing improves significantly from childhood to adolescence in patients with cleft lip and palate and cleft palate only.

Structural Abnormalities of the Central Auditory Pathway in Infants with Nonsyndromic Cleft Lip and/or Palate

Objective

To investigate possible structural abnormalities of the central auditory pathway in infants with nonsyndromic cleft lip and/or palate (NSCL/P).

Participants

Twenty-seven Chinese infants with NSCL/P, aged from 6 to 24 months.

Intervention

Morphological magnetic resonance imaging (MRI) measurements of the central auditory nervous system (CANS) in infants with NSCL/P were analyzed and compared with those of age- and sex-matched normal controls.

Results

No significant group differences were found in general brain measurements, including volumes of the brain stem and right hemisphere. However, infants with NSCL/P had statistically significantly smaller volumes of the left thalamus and left auditory cortex and notably decreased thickness of the left auditory cortex.

Conclusion

Cortical abnormalities were more marked compared with other MRI measurements. Structural CANS abnormalities in infants with NSCL/P may be located mainly in the left cerebral hemisphere. The development and maturation of the auditory cortex in infants with NSCL/P may be abnormal when compared with those of normal children.

Central auditory nervous system dysfunction in infants with non-syndromic cleft lip and/or palate

OBJECTIVE

Peripheral hearing loss has been commonly reported in children with non-syndromic cleft lip and/or palate (NSCLP) but few studies have provided information about central auditory nervous system (CANS) functioning for this group. The main objective of this study was to explore CANS functioning in infants with NSCLP through analysis of auditory evoked potentials (AEPs).

METHODS

AEPs including auditory brainstem response (ABR), middle latency response (MLR), and mismatch negativity (MMN) recordings were conducted in 34 infants of Chinese ethnicity with NSCLP and an equivalent number of normal controls.

RESULTS

There was no significant difference in ABR (all measurements, including wave I, III, V latencies, I-V inter-wave latency, and wave V amplitude), or MLR (recordable components, Na, Pa latencies, and Na-Pa amplitude) findings between the two groups. However, infants with NSCLP had a significantly smaller MMN response than their normal controls, using MMN strength as the measurement.

CONCLUSIONS

Significant abnormal auditory evoked potential findings at the cortical level suggest that infants with NSCLP may be at risk of central auditory discrimination dysfunction. Further effort is needed to determine auditory processing abilities in infants with NSCLP.
