Impact of auditory variables on consonant production in babbling and early speech in children with moderate hearing loss - a longitudinal study.

This longitudinal study aimed to investigate early consonant production and the impact of hearing aid (HA) use, and aided audibility in Swedish children with moderate hearing loss (CHL) who received amplification before 6 months of age. CHL (n = 11) and children with normal hearing (CNH) (n = 11) were followed-up at 10, 18, and 36 months of age. At 10 months of age, the CHL used significantly fewer oral stops (p < 0.01), dental/alveolar stops (p < 0.05) and had a significantly fewer number of different true consonants (p < 0.01). At 18 months, there were no significant differences between the groups regarding presence of oral stops, and dental/alveolar stops, but the significant difference in the number of different true consonants remained (p < 0.00). At 36 months of age, consonant proficiency did not differ between the groups. A higher number of hours of HA use was associated with the presence of consonant variables at 10 months. Aided audibility showed weak to moderate correlations with number of consonants produced and proficiency. This group of children presented with initial delays in their early consonant production but seemed to catch up as they aged. Consistency of HA use from initial fitting is an important factor that may decrease the possible delays in the development of early consonant production and proficiency in CHL by 36 months of age.

Expressive vocabulary development in children with moderate hearing loss - the impact of auditory variables and early consonant production.

In this study, the early expressive vocabulary development was investigated in a group of children with moderate hearing loss (HL). Size and development of expressive vocabulary from 18 30 months were analyzed and compared to a group of children with normal hearing (NH). For the children with HL, the impact of auditory variables on number of words were examined. The relationship of early consonant production to number of words produced of both groups were examined and the phonological complexity of reported words was compared between the groups. The results showed that children with HL (n = 8) produced a similar number of words as the NH (n = 8) at 18 months, but fewer at 24 and 30 months. Hours of HA use showed significant correlations to number of words. The number of different true consonants at 18 months for the whole group showed a significant relationship to number of words produced at 24 months. No significant differences were found between children with HL and NH children regarding phonological complexity of reported words. The findings indicate that the children born with moderate HL who were fitted with hearing aids (HAs) before 6 months of age are at risk in their development of expressive vocabulary. Full-time use of HAs and monitoring of early consonant use should be encouraged in the early intervention of this target group.

Clinical Decision Support Tools for Predicting Outcomes in Patients Undergoing Total Knee Arthroplasty: A Systematic Review.

BACKGROUND: Total knee arthroplasty is the standard surgical treatment for end-stage osteoarthritis. Although widely accepted as a successful procedure, approximately 30% of patients are not satisfied due to non-optimal postoperative outcomes. Clinical decision support tools that are able to accurately predict post-surgery outcomes would assist in providing individualized advice or services to help alleviate possible issues, resulting in significant benefits to both the healthcare system and individuals. METHODS: Five databases (Ovid Medline, Ovid EMBASE, CINAHL complete, Cochrane Library, and Scopus) were searched for the key phrases "knee replacement" or "knee arthroplasty" and "decision support tool," "decision tool," "predict∗ tool," "predict∗ model," "algorithm" or "nomogram." Searches were limited to peer-reviewed journal articles published between January 2000 and June 2019. Reference lists of included articles were examined. Authors came to a consensus on the final list of included articles. RESULTS: Eighteen articles were included for review. Most models reported low predictive success and inability to externally validate. Both candidate and final predictor variables were inconsistent between studies. Only 1 model was considered strongly predictive (AUROC >0.8), and only 2 studies were able to externally validate their developed model. In general, models that performed well used large patient numbers, were tested on similar demographics, and used either nonlinear input transformations or a completely nonlinear model. CONCLUSION: Some models do show promise; however, there remains the question of whether the reported predictive success can continue to be replicated. Furthermore, clinical applicability and interpretation of predictive tools should be considered during development.

Canonical Babbling and Early Consonant Development Related to Hearing in Children With Otitis Media With Effusion With or Without Cleft Palate.

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.

Schoolchildren with unilateral or mild to moderate bilateral sensorineural hearing loss should be screened for neurodevelopmental problems.

AIM: The aim was to assess the rate and overlap of language and other neurodevelopmental problems in children aged 9-12 years with unilateral or mild to moderate bilateral sensorineural hearing loss. METHODS: Caregivers of 24 of the 58 eligible children, born 2004-2007, registered at the regional audiology department in Gothenburg, Sweden, with these types of hearing loss completed the Five-to-Fifteen questionnaire, a comprehensive screening instrument for neurodevelopmental problems. Of these 24 children, 21 were assessed with the Clinical Evaluation of Language Fundamentals-Fourth Edition (CELF-4). Children with scores indicating definite problem on the Five-to-Fifteen questionnaire and their parents were invited to a clinical neuropaediatric assessment. RESULTS: Of the 24 children, 13 (54%) screened positive for definite neurodevelopmental problems. Clinical assessments confirmed the presence of at least one neurodevelopmental disorder in eight of these 24, corresponding to 33%. Seven (33%) of the 21 children participating in the CELF-4 had scores indicating a language disorder, of whom four children had a neurodevelopmental disorder according to the neuropaediatric assessment. CONCLUSION: The results support that schoolchildren with unilateral or mild to moderate bilateral sensorineural hearing loss should undergo neurodevelopmental screening to identify possible coexisting neurodevelopmental problems or disorders.

Validation of the Swedish version of the LittlEARS® Auditory Questionnaire in children with normal hearing - a longitudinal study.

Objective: To externally validate the Swedish version of the LittlEARS® Auditory Questionnaire (LEAQ) in children with normal hearing followed longitudinally, and to examine to what extent the LEAQ correlates to other measures of auditory and language development. Design: The Swedish version of the LEAQ was completed every other month over a 2-year period and correlated with the Parents' Evaluation of Aural/Oral Performance of Children (PEACH) and McArthur-Bates Communicative Development Inventory (CDI) to examine overlapping areas of development. Normative curve was derived through linear mixed models and the effect of time investigated with repeated measures ANOVA. Study sample: Parents of 25 typically developing children with normal hearing (13 girls, 12 boys). Results: The norm curve of the Swedish LEAQ showed a similar equation as the original German version and the effect of time was significant. Correlations between LEAQ and CDI were moderate to high, and between LEAQ and PEACH weak or non-existing. Conclusion: The Swedish version of the LEAQ is a reliable tool in accordance with the original version. However, results indicate that this questionnaire to a large extent measures language skill rather than audition specifically.

Phonology in Swedish-speaking 3-year-olds born with cleft lip and palate and the relationship with consonant production at 18 months.

BACKGROUND: Approximately 50% of children born with cleft palate present speech difficulties around 3 years of age, and several studies report on persisting phonological problems after palatal closure. However, studies on early phonology related to cleft palate are few and have so far mainly been carried out on English-speaking children. Studies on phonology related to cleft palate in languages other than English are also warranted. AIMS: To assess phonology in Swedish-speaking children born with and without unilateral cleft lip and palate (UCLP) at 3 years of age, and to identify variables at 18 months that are associated with restricted phonology at age 3 years. METHODS & PROCEDURES: Eighteen consecutive children born with UCLP and 20 children without cleft lip and palate were included. Transcriptions of audio recordings at 18 months and 3 years were used. Per cent correct consonants adjusted for age (PCC-A), the number of established phonemes, and phonological simplification processes at 3 years were assessed and compared with different aspects of consonant inventory at 18 months. OUTCOMES & RESULTS: PCC-A, the number of established phonemes, and the total number of phonological processes differed significantly at 3 years between the two groups. Total number of oral consonants, oral stops, dental/alveolar oral stops and number of different oral stops at 18 months correlated significantly with PCC-A at 3 years in the UCLP group. CONCLUSIONS & IMPLICATIONS: As a group, children born with UCLP displayed deviant phonology at 3 years compared with peers without cleft lip and palate. Measures of oral consonant and stop production at 18 months might be possible predictors for phonology at 3 years in children born with cleft palate.

A longitudinal study of hearing and middle ear status of individuals with cleft palate with and without additional malformations/syndromes.

Objective : To describe and compare the middle ear status and hearing sensitivity in adolescence with isolated cleft palate plus additional malformations and/or syndromes with those with only an isolated cleft palate. Design : Retrospective and longitudinal. Two groups of individuals with isolated cleft palate were compared. Participants : A cohort of individuals born over 4 years in the western region of Sweden. The cohort was divided into one group with isolated cleft palate (n = 31; ICP) and one group with isolated cleft palate plus additional malformations and/or syndromes (n = 37; ICP+). Methods : Middle ear status and hearing thresholds were collected from the medical records at 7, 10, 13, and 16 years of age, examined, and compared within and between groups over time. Results : The ICP+ group demonstrated a significantly higher prevalence of abnormal middle ear status and elevated hearing thresholds as compared with the ICP group. As the individuals aged, the prevalence of abnormal middle ear status decreased. The hearing levels in both groups decreased in the low to middle frequencies as individuals aged; however, the hearing in the high frequencies did not. Conclusions : Individuals with cleft palate need to be followed routinely for middle ear status and hearing thresholds to ensure optimal audiological rehabilitation, with particular attention to those with additional malformations and/or syndromes.

Using Presurgical Biopsychosocial Features to Develop an Advanced Clinical Decision-Making Support Tool for Predicting Recovery Trajectories in Patients Undergoing Total Knee Arthroplasty: Protocol for a Prospective Observational Study.

BACKGROUND: Following total knee arthroplasty (TKA), 10% to 20% of patients report dissatisfaction with procedural outcomes. There is growing recognition that postsurgical satisfaction is shaped not only by the quality of surgery but also by psychological and social factors. Surprisingly, information on the psychological and social determinants of surgical outcomes is rarely collected before surgery. A comprehensive collection of biopsychosocial information could assist clinicians in making recommendations in relation to rehabilitation, particularly if there is robust evidence to support the ability of presurgical constructs to predict postsurgical outcomes. Clinical decision support tools can help identify factors influencing patient outcomes and support the provision of interventions or services that can be tailored to meet individuals' needs. However, despite their potential clinical benefit, the application of such tools remains limited. OBJECTIVE: This study aims to develop a clinical decision tool that will assist with patient stratification and more precisely targeted clinical decision-making regarding prehabilitation and rehabilitation for TKA, based on the identified individual biopsychosocial needs. METHODS: In this prospective observational study, all participants provided written or electronic consent before study commencement. Patient-completed questionnaires captured information related to a broad range of biopsychosocial parameters during the month preceding TKA. These included demographic factors (sex, age, and rurality), psychological factors (mood status, pain catastrophizing, resilience, and committed action), quality of life, social support, lifestyle factors, and knee symptoms. Physical measures assessing mobility, balance, and functional lower body strength were performed via video calls with patients in their home. Information related to preexisting health issues and concomitant medications was derived from hospital medical records. Patient recovery outcomes were assessed 3 months after the surgical procedure and included quality of life, patient-reported knee symptoms, satisfaction with the surgical procedure, and mood status. Machine learning data analysis techniques will be applied to determine which presurgery parameters have the strongest power for predicting patient recovery following total knee replacement. On the basis of these analyses, a predictive model will be developed. Predictive models will undergo internal validation, and Bayesian analysis will be applied to provide additional metrics regarding prediction accuracy. RESULTS: Patient recruitment and data collection commenced in November 2019 and was completed in June 2022. A total of 1050 patients who underwent TKA were enrolled in this study. CONCLUSIONS: Our findings will facilitate the development of the first comprehensive biopsychosocial prediction tool, which has the potential to objectively predict a patient's individual recovery outcomes following TKA once selected by an orthopedic surgeon to undergo TKA. If successful, the tool could also inform the evolution rehabilitation services, such that factors in addition to physical performance can be addressed and have the potential to further enhance patient recovery and satisfaction.

Hearing aid use in 11-year-old children with mild bilateral hearing loss: Associations between parent and child ratings and datalogging.

OBJECTIVE: This study examined the hearing aid use in older school-aged children with mild bilateral hearing loss. More specifically, it investigated children's and parents' estimation of use in comparison to datalogging as well as explored the situations children used their hearing aids. METHODS AND MATERIALS: Sixteen children with mild bilateral hearing loss and their parents participated. Of those, 14 children used hearing aids. Children and parents completed a questionnaire on hours of hearing aid use and situations hearing aids were used. Datalogging of the hearing aids was recorded and compared to the outcome of the questionnaires. RESULTS: Datalogging indicated average hearing aid use time was 6.6 h. Children significantly overestimated their use of their hearing aids while approximately half the parents overestimated their child's use. Children used their hearing aids most often at school and in the car. CONCLUSION: Children with mild bilateral hearing loss overestimate the amount of time they are wearing their hearing aids. This may impact counselling and intervention on the use of hearing aids. Therefore, school-aged children should be included in the discussions around potentially increasing use of hearing aids.

Expressive vocabulary of school-age children with mild to moderately severe hearing loss.

OBJECTIVES: The main goal of this study was to describe the expressive vocabulary of school-age children with mild to moderately severe hearing loss (CHL group) and to compare their performance with children with normal hearing (CNH group) of the same age. Another aim was to examine the interaction between nonword repetition and expressive vocabulary size. Furthermore, the interaction between results on vocabulary tests and background factors, such as the age of diagnosis, age of hearing aid fitting, and amount of hearing aid use, was explored. METHOD: School-aged children with mild to moderately severe, permanent bilateral hearing loss and children with normal hearing were included in this cross-sectional study. The children participated in assessments of naming pictures, defining words, and repetition of nonwords and sentences. Results of the CHL group and the CNH group were compared. The analysis also included the degree of hearing loss, the age of diagnosis, amount of hearing aid use, and level of parental education. RESULTS: The CHL group performed significantly below the CNH group on all measures: picture naming, defining words, nonword repetition, and repetition of sentences. The proportion of words pronounced with correct phonological structure when picture naming was more limited in the CHL group than in the CNH group. There was a significant positive correlation between the amount of hearing aid use and nonword repetition ability in the CHL group. Age of diagnosis and age of hearing aid fitting was not significantly correlated with the outcomes of the vocabulary assessments in this study. CONCLUSION: Despite the technological advancement of hearing aids, the expressive vocabulary in school-aged children with mild to moderately severe, permanent bilateral, hearing impairment does not reach the same level as for children with normal hearing, although there is a variation in performance within the group. The variation in the CHL group was not uniquely impacted by either age, degree of hearing loss, or the age of diagnosis. The amount of hearing aid use seems to impact the perception of new words. More studies of expressive vocabulary are needed, because they capture a dimension of word learning that seems particularly sensitive to hearing loss and hearing aid use.

Early consonant production in Swedish infants with and without unilateral cleft lip and palate and two-stage palatal repair.

OBJECTIVE: To investigate consonant production at 12 and 18 months of age following early soft palate repair in infants with unilateral cleft lip and palate (UCLP), and to compare it with typically developing children without clefts. DESIGN: Randomized study with comparison group. PARTICIPANTS: Twenty Swedish infants born with UCLP and 21 without clefts (COMP) were included in a randomized trial of palatal surgery (Scandcleft project). Soft palate closure was completed at age 5 months; hard palate closure was performed in 11 of the infants with UCLP at 1 year of age (HPC) and was left open in nine (HPO). METHOD: Audio recordings at 12 months (UCLP  =  9, COMP  =  21) and at 18 months (UCLP  =  18, COMP  =  21) were phonetically transcribed. Consonant inventory, frequency of manner and place of articulation, true canonical babbling (TCB), and impact of hearing status were analyzed. RESULTS: At 12 months of age, all children had reached the stage of TCB. Mild hearing impairment was significantly correlated with fewer consonant types. A lower frequency of dentals and oral stops was found in the UCLP group than in the COMP group. However, the number of oral stops was high compared with what has been previously reported. CONCLUSIONS: Early soft palate closure seems to give a relatively high number of oral stops even with the hard palate unrepaired, although with significantly fewer dentals/alveolars than are seen in peers without clefts. Differences in consonant inventory were correlated with hearing function.

Hearing Aid Use, Auditory Development, and Auditory Functional Performance in Swedish Children With Moderate Hearing Loss During the First 3 Years.

Purpose This study investigated longitudinal hearing aid (HA) use in a cohort of children with moderate hearing loss (CHL), fitted with amplification before the age of 6 months. Additionally, the relationship of HA use and aided audibility on outcomes of parental questionnaires of auditory skills was examined, and these outcomes were compared to a group of children with normal hearing (CNH). Method Nine CHL and 29 CNH and their parents participated in the study. Measures were collected at initial fitting, 10, 18, 24, 30, and 36 months of age. Parents reported hours of HA use and situations the HAs were used. Datalogging and speech intelligibility index were also collected. Auditory skills were measured through parental questionnaires. Results The mean hours of HA use/day for this cohort increased from 7.55 at the ages of 10 months to 10.15 at 36 months according to datalogging. Parental estimations of hours of HA use and in which situations varied between subjects. Correlations between HA use from datalogging and speech intelligibility index to measures of auditory skills were weak. CHL showed similar results to CNH on auditory development at the ages of 10, 18, and 24 months but presented with significantly lower scores on auditory functional performance in noise at 30 and 36 months of age. Conclusions Longitudinal monitoring of HA use from fitting of amplification with the combination of objective and subjective tools may have a positive impact on HA use in CHL. The lower scores on listening in noise compared to CNH call for further attention.

Single-Sided Deafness-Outcomes of Three Interventions for Profound Unilateral Sensorineural Hearing Loss: A Randomized Clinical Trial.

OBJECTIVE: A comparison of three interventions for profound unilateral sensorineural hearing loss. STUDY DESIGN: Prospective, crossover randomized clinical trial. PARTICIPANTS: Fifteen participants with profound unilateral sensorineural hearing loss. INTERVENTIONS: Three potential technical interventions were compared: Bone Conduction Device on softband, Contralateral Routing of Signal (CROS), and Remote Microphone . Each intervention was randomly trialed for a period of 3 weeks, separated by a 1 week washout period. OUTCOME MEASURES: Speech in noise recognition test performed under four conditions (lateral noise poorer ear, lateral noise better ear, speech poorer ear, speech better ear). Standardized questionnaires (Abbreviated Profile of Hearing Aid Benefit, Bern Benefit in Single Sided Deafness Questionnaire, and Speech, Spatial, and Other Qualities 12) were used to evaluate amplification benefit at baseline and following each intervention. RESULTS: The use of remote microphone provided the best results in the speech recognition in noise test. A benefit in some signal-to-noise ratios was presented of the CROS over bone conduction device on softband in the Speech Poor Ear condition. On questionnaires of benefit, participants did not rate a particular intervention as significantly better than any other. Following the study, CROS was the intervention preferred by the 8 of 15 participants (53%). The majority of participants (80%) chose to continue with an intervention rather than no treatment. CONCLUSION: The use of all interventions resulted in increased performance in speech recognition in noise and rated higher on subjective benefits in comparison with baseline. People with SSD are a heterogeneous population when considering perceived difficulties. Future research should focus on segmenting the population of SSD depending on factors such as etiology, high frequency loss in the better ear, and age of acquired loss for the poorer ear. This stratification may possibly increase the benefit for the patient in terms of more individual-based clinical routines.

Improving Patient Outcomes Following Total Knee Arthroplasty: Identifying Rehabilitation Pathways Based on Modifiable Psychological Risk and Resilience Factors.

Total knee arthroplasty (TKA) is a commonly implemented elective surgical treatment for end-stage osteoarthritis of the knee, demonstrating high success rates when assessed by objective medical outcomes. However, a considerable proportion of TKA patients report significant dissatisfaction postoperatively, related to enduring pain, functional limitations, and diminished quality of life. In this conceptual analysis, we highlight the importance of assessing patient-centered outcomes routinely in clinical practice, as these measures provide important information regarding whether surgery and postoperative rehabilitation interventions have effectively remediated patients' real-world "quality of life" experiences. We propose a novel precision medicine approach to improving patient-centered TKA outcomes through the development of a multivariate machine-learning model. The primary aim of this model is to predict individual postoperative recovery trajectories. Uniquely, this model will be developed using an interdisciplinary methodology involving non-linear analysis of the unique contributions of a range of preoperative risk and resilience factors to patient-centered TKA outcomes. Of particular importance to the model's predictive power is the inclusion of a comprehensive assessment of modifiable psychological risk and resilience factors that have demonstrated relationships with TKA and other conditions in some studies. Despite the potential for patient psychological factors to limit recovery, they are typically not routinely assessed preoperatively in this patient group, and thus can be overlooked in rehabilitative referral and intervention decision-making. This represents a research-to-practice gap that may contribute to adverse patient-centered outcomes. Incorporating psychological risk and resilience factors into a multivariate prediction model could improve the detection of patients at risk of sub-optimal outcomes following TKA. This could provide surgeons and rehabilitation providers with a simplified tool to inform postoperative referral and intervention decision-making related to a range of interdisciplinary domains outside their usual purview. The proposed approach could facilitate the development and provision of more targeted rehabilitative interventions on the basis of identified individual needs. The roles of several modifiable psychological risk and resilience factors in recovery are summarized, and intervention options are briefly presented. While focusing on rehabilitation following TKA, we advocate for the broader utilization of multivariate prediction models to inform individually tailored interventions targeting a range of health conditions.

Hearing thresholds and ventilation tube treatment in children with unilateral cleft lip and palate.

OBJECTIVE: Children with cleft lip and palate have a high prevalence of otitis media with effusion (OME) which is often associated with a fluctuating, conductive hearing loss in the low and mid-frequencies and a risk for permanent hearing loss in the higher frequencies. Although common, there is no consensus on the treatment of OME with ventilation tubes. The aim of this study is to document if the risk for permanent hearing loss and acquired cholesteatoma increases due to treatment with ventilation tubes (VT treatments) during childhood in a group of children with cleft lip and palate. METHODS: A retrospective medical chart review of 33 children (25 boys and 8 girls) born with unilateral cleft lip and palate (UCLP) was completed. Audiological data (results of hearing sensitivity tests, the total number of hearing tests, and number of VT treatments) were extracted from medical records from when the children were 4-7 and >7-10 years of age. RESULTS: The hearing thresholds in the speech frequencies improved with age (p < 0,05) but a minority of the children continued to present with elevated hearing thresholds in the higher frequencies at >7-10 years of age. There were no significant correlations between number of VT treatments and hearing thresholds at >7-10 years. Four of the 33 children presented with complications: two children exhibited perforations of the ear drum (6.1%) and two children developed unilateral cholesteatoma (6.1%). CONCLUSION: In the current study, the hearing sensitivity of children with cleft lip and palate improved with age. However, this improvement was not seen in the higher frequencies. Twelve percent of the children experienced complications following VT treatments. Due to these complications, it is recommended that all children with cleft palate should have routine follow-ups by an ENT doctor and audiologist. As part of the routine follow-up care, hearing assessments should be performed before and after VT treatments.

A longitudinal study of hearing and middle ear status in individuals with UCLP.

OBJECTIVE: To define the age when the higher prevalence of abnormal middle ear dissipates in individuals with cleft lip and palate and to investigate how this may affect hearing sensitivity over time. STUDY DESIGN: Retrospective and prospective cohort study. SETTING: University hospital. PATIENTS: Three groups of individuals with unilateral cleft lip and palate from the same cleft center: 1) a group of individuals followed longitudinally from 1 to 5 years of age (n = 22), 2) another group of individuals followed longitudinally from 7 to 16 years of age (n = 24), and 3) a group which encompasses young adults between 20 and 31 years of age (n = 26). MAIN OUTCOMES MEASURE(S): Abnormal middle ear status and hearing sensitivity. RESULTS: The prevalence of abnormal middle ear status decreases as the individuals within the 3 groups age from 89% at age 1 year to 10% in young adulthood. Hearing statistically improved as children became older up to 13 years of age and then worsened in the high frequencies between 16 and 20 to 31 years of age. CONCLUSION: There is a high prevalence of abnormal middle ear status in individuals with cleft lip and palate. This higher prevalence of abnormal middle ear status may lead to poorer high-frequency hearing, which could potentially lead to challenges in academics and difficulties understanding speech in social situations. Further investigation into these, the prevalence of abnormal middle ear status and hearing in comparison to a control group is warranted.

A longitudinal study of hearing and middle ear status in adolescents with cleft lip and palate.

OBJECTIVES/HYPOTHESIS: To study longitudinal prevalence of otitis media with effusion (OME) in children between 7 and 16 years of age by cleft group, and hearing sensitivity across time and across frequencies. STUDY DESIGN: Retrospective and longitudinal. METHODS: All children with cleft palate born from 1991 to 1993 were included in the study (n = 58). Audiological and otological data were reviewed at 7, 10, 13, and 16 years of age. The group was divided by cleft type (24 unilateral cleft lip and palate, 23 cleft palate only, and 11 bilateral cleft lip and palate). RESULTS: The prevalence of abnormal middle ear status decreased significantly with age. When comparing cleft types, the isolated cleft palate group presented with a significantly lower prevalence of abnormal middle ear status than the other groups at 7 and 16 years of age (21% as compared to 32% in the unilateral group and 38% in the bilateral group). The pure-tone average improved with age, while the high-frequency pure-tone average did not. When cleft types were compared, the bilateral group demonstrated significantly poorer hearing in the high frequencies than the other groups. CONCLUSION: Children with cleft palate need regular audiological and otological follow-up to ensure management is appropriate and timely. The increased hearing thresholds in the high frequencies may be due to the increased episodes of OME.

Hearing and otitis media with effusion in young adults with cleft lip and palate.

CONCLUSION: Speech recognition in noise is affected when otitis media with effusion (OME) is present in young adults with unilateral cleft lip and palate. OBJECTIVE: The objective of this study was to describe the hearing and performance on auditory tasks of young adults with unilateral cleft lip and palate as compared to young adults without cleft lip and palate. METHODS: Twenty-six young adults with unilateral cleft lip and palate and 23 young adults without cleft lip and palate participated in the study. Pure tone audiometry, tympanometry, speech recognition in noise at the word and sentence level, and masking level difference were examined. RESULTS: Results revealed elevated hearing thresholds in the young adults with cleft lip and palate as compared with young adults without cleft lip and palate. No differences concerning speech recognition in noise and binaural processing were observed between the young adults with cleft lip and palate and those without. However, there was poorer speech recognition performance in those adults with unilateral cleft lip and palate and OME on the day of testing as compared with young adults with unilateral cleft lip and palate without OME on the day of testing.
