Centre-level variation in speech outcome and interventions, and factors associated with poor speech outcomes in 5-year-old children with non-syndromic unilateral cleft lip and palate: The Cleft Care UK study. Part 4

Exploring the relationship between cleft type and speech outcome in 4-to-6-year-olds with non-syndromic cleft palate using different measures: A preliminary report

Cleft type affects speech outcomes, but exact relationships remain unclear as outcome measures vary. The primary aim was to investigate the relationship between cleft type and speech outcome using different measures in 4-to-6-year-olds with non-syndromic clefts. Secondary aims were to explore the relationships between (i) speech measures used; and (ii) parent perception of speech intelligibility and listener familiarity. Twenty-two pre-schoolers with clefts, plus one parent for each child, were recruited through a hospital outpatient clinic. Children with cleft lip and palate (CLP; n = 11) and those with cleft palate only (CP; n  = 11), matched on age and time of palate repair, were compared on Percentage Consonants Correct (PCC), clinician-reported speech intelligibility, and parent rating on the Intelligibility-in-Context Scale (ICS). Children with CLP had significantly lower PCC scores than children with CP (p = .020), but had no significant differences in their clinician- or parent-reported speech intelligibility. Clinician-reported speech intelligibility correlated significantly with both PCC (τ = .594, p < 0.01) and ICS (τ = .424, p  = 0.009). No significant correlation was found between PCC and ICS (τ =.197, p = 0.113). Overall, parents rated their child's intelligibility higher for familiar compared to unfamiliar communication partners (τ  = 2.325, p = 0.001, r  = .76). Cleft type is crucial for intervention planning when objective measures are employed. Speech outcomes should be evaluated at impairment, activity, and participation levels, and by different communication partners, to comprehensively evaluate communicative effectiveness.

Reliability of data on percent consonants correct and its associated quality indicator in the Swedish cleft lip and palate registry

BACKGROUND

Data in national health care quality registries must be valid and reliable in order to enable open comparisons of results.

AIM

To assess the reliability of data on percent consonants correct (PCC) and its associated quality indicator ≥86% correct consonants in the Swedish quality registry for patients born with cleft lip and palate (CLP) registry.

METHODS

Six independent speech-language pathologists re-assessed the audio recordings of 96 five-year-olds with PCC data in the CLP registry. Target consonants of a single-word picture-naming test were phonetically transcribed, and PCC was calculated. The reliability of PCC data was assessed with the intraclass correlation coefficient (ICC). The reliability of the quality indicator ≥86% correct consonants was assessed with point-by-point percentage agreement and Cohen's kappa.

RESULTS

Intra- and inter-judge agreement for PCC was excellent with ICCs above 0.9, and so was the agreement of data from the CLP registry and the six judges' re-assessments. The percentage agreement between all judges and the CLP registry for the quality indicator ≥86% correct consonants was poor (67%). However, in 88% of the cases, results from four judges and the CLP registry agreed, corresponding to good agreement. The mean of all kappa values for six judges and the CLP registry corresponded to good agreement (0.72).

CONCLUSIONS

The results indicate the PCC data in the CLP registry and the quality indicator ≥86% correct consonants to be reliable. When differences in outcome between treatment centres are detected, the raw data collected should always be re-examined before drawing definitive conclusions.

Surgical treatment of velopharyngeal dysfunction: Incidence and associated factors in the Swedish cleft palate population

INTRODUCTION

Speech in children with cleft palate can be affected by velopharyngeal dysfunction, which persists after primary palate repair. The incidence of surgery to correct velopharyngeal dysfunction in this patient group has previously been reported as 2.6-37%. We aimed to investigate the incidence of velopharyngeal dysfunction surgery in Swedish children with cleft palate and to examine potential associations of independent variables with this incidence.

METHODS

In this cohort study, we analysed data from the Swedish cleft lip and palate quality registry for 1093 children with cleft palate with or without cleft lip. Kaplan-Meier analysis was used to estimate the risk of having velopharyngeal dysfunction surgery. Multivariable Cox proportional hazards models were used to estimate the associated effect of cleft subtype, additional diagnoses, gender, and age at and number of stages for primary palate repair on the primary outcome.

RESULTS

The risk of having velopharyngeal dysfunction surgery was 25.6%. Complete primary palate repair after the age of 18 months or in more than one stage was associated with a higher risk, but it could not be determined which of these was the more significant factor. Cleft soft palate was associated with a significantly lower risk than other cleft subtypes.

CONCLUSIONS

Primary palate repair at a higher age or in more than one stage may increase the risk of having velopharyngeal dysfunction surgery. Further analysis of potential unknown confounding factors and the association between the incidence of velopharyngeal dysfunction and surgery to correct this condition is needed.

Considering the role of speech processing in cleft-related speech sound disorders: Implications for causal pathways and classification systems

BACKGROUND

Classification systems in healthcare support shared understanding of conditions for clinical communication, service monitoring and development, and research. Children born with cleft palate with or without cleft lip (CP+/-L) are at high risk of developing cleft-related speech sound disorder (SSD). The way cleft-related SSD is represented and described in SSD classification systems varies. Reflecting on the potential causal pathways for different cleft-related speech features, including the role of speech processing skills, may inform how cleft-related SSD is represented in classification systems.

AIM & APPROACH

To explore and reflect on how cleft-related SSD is represented in current SSD classification systems in the context of considering how speech processing skills and other factors may be involved in causal pathways of cleft speech characteristics (CSCs).

MAIN CONTRIBUTION

Variation in the representation of cleft-related SSD in classification systems is described. Potential causal pathways for passive cleft- related speech features and different active CSCs are explored. The factors involved in the development and/or persistence of different active CSCs may vary. Some factors may be specific to children born with CP+/-L, but if speech processing skills are also involved, this is an overlap with other SSD subtypes. Current evidence regarding relationships between different speech processing skills and active CSCs is limited. Implications for the representation of cleft-related SSD in SSD classification systems are discussed.

CONCLUSION

There are different categories of cleft-related speech features which are essential to understand and identify in children with cleft-related SSD to ensure appropriate management. Representation of these feature categories in classification systems could support understanding of speech in this population. Speech processing skills could be involved in the development and/or persistence of different active CSCs in individual children. Reflection and discussion on how cleft-related SSD is represented in classification systems in relation to other SSD subtypes may inform future iterations of these systems. Further work is needed to understand factors influencing the development and/or persistence of active CSCs, including speech processing skills.

WHAT THIS PAPER ADDS

What is already known on the subject Cleft-related speech sound disorder (SSD) is commonly described as being of known origin. The features of cleft-related SSD have been described extensively and several authors have also examined factors which may contribute to speech development and outcomes in children born with cleft palate +/- lip. There is limited evidence regarding the role of speech processing in the development and persistence of cleft-related SSD. What this study adds This paper reflects on how cleft-related SSD is represented in SSD classification systems in relation to key feature categories of cleft-related SSD and possible causal pathways for passive features and active cleft speech characteristics (CSCs). The role of cognitive speech processing skills is specifically considered alongside other factors that may contribute to the development of active CSCs. What are the clinical implications of this work? Causal pathways for different features of cleft-related SSD may vary, particularly between passive and active features, abut also between different active CSCs. Speech and language therapists (SLTs) need to differentially diagnose passive speech features and active CSCs. Consideration of the role of different speech processing skills and interactions with other potentially influencing factors in relation to active CSCs may inform clinical hypotheses and speech and language therapy (SLT) intervention. Representing key features of cleft-related SSD in classification systems may support understanding of cleft-related SSD in relation to other SSD subtypes.

Investigating the Impact of Patient-Related Factors on Speech Outcomes at 5 Years of Age in Children With a Cleft Palate

To investigate the relationship between patient-related factors (sex, cleft type, cleft extent, and Robin Sequence [RS]) and speech outcome at 5 years of age for children born with a cleft palate ±  lip (CP ± L).

3157 Children (1426 female:1731 male) with a nonsyndromic CP ± L, born between 2006 and 2014 in England, Wales, and Northern Ireland.

Perceptual speech analysis utilized the Cleft Audit Protocol for Speech-Augmented (CAPS-A) rating and UK National Speech Outcome Standards: Speech Standard 1 (SS1)-speech within the normal range, SS2a-no structurally related speech difficulties or history of speech surgery, and SS3-speech without significant cleft-related articulation difficulties.

Odds of achieving SS1 were lower among boys (aOR 0.771 [CI 0.660-0.901]), those with clefts involving the lip and palate (vs palate only) (UCLP-aOR 0.719 [CI 0.591-0.875]; BCLP-aOR 0.360 [CI 0.279-0.463]), and clefts involving the hard palate (incomplete-aOR 0.701 [CI 0.540-0.909]; complete-aOR 0.393 [CI 0.308-0.501]). Similar relationships with these patient factors were observed for SS3. SS2 was affected by the extent of hard palate involvement (complete; aOR 0.449 [CI 0.348-0.580]). Although those with CP and RS were less likely to meet all 3 standards than those without RS, odds ratios were not significant when adjusting for sex and cleft extent.

Sex, cleft type, and extent of hard palate involvement have a significant impact on speech outcome at 5 years of age. Incorporating these factors into risk-adjustment models for service-level outcome reporting is recommended.

Using "Real-World Data" to Study Cleft Lip/Palate Care: An Exploration of Speech Outcomes from a Multi-Center US Learning Health Network

OBJECTIVE

To assess the ability of a cleft-specific multi-site learning health network registry to describe variations in cleft outcomes by cleft phenotypes, ages, and treatment centers. Observed variations were assessed for coherence with prior study findings.

DESIGN

Cross-sectional analysis of prospectively collected data from 2019-2022.

SETTING

Six cleft treatment centers collected data systematically during routine clinic appointments according to a standardized protocol.

PARTICIPANTS

714 English-speaking children and adolescents with non-syndromic cleft lip/palate.

INTERVENTION

Routine multidisciplinary care and systematic outcomes measurement by cleft teams.

OUTCOME MEASURES

Speech outcomes included articulatory accuracy measured by Percent Consonants Correct (PCC), velopharyngeal function measured by Velopharyngeal Competence (VPC) Rating Scale (VPC-R), intelligibility measured by caregiver-reported Intelligibility in Context Scale (ICS), and two CLEFT-Q™ surveys, in which patients rate their own speech function and level of speech distress.

RESULTS

12year-olds exhibited high median PCC scores (91-100%), high frequency of velopharyngeal competency (62.50-100%), and high median Speech Function (80-91) relative to younger peers parsed by phenotype. Patients with bilateral cleft lip, alveolus, and palate reported low PCC scores (51-91%) relative to peers at some ages and low frequency of velopharyngeal competency (26.67%) at 5 years. ICS scores ranged from 3.93-5.0 for all ages and phenotypes. Speech Function and Speech Distress were similar across phenotypes.

CONCLUSIONS

This exploration of speech outcomes demonstrates the current ability of the cleft-specific registry to support cleft research efforts as a source of "real-world" data. Further work is focused on developing robust methodology for hypothesis-driven research and causal inference.

Scandcleft randomized trials of primary surgery for unilateral cleft lip and palate: Speech proficiency at 10 years of age

BACKGROUND & AIM

To assess consonant proficiency and velopharyngeal function in 10-year-old children born with unilateral cleft lip and palate (UCLP) within the Scandcleft project.

METHODS & PROCEDURES

Three parallel group, randomized, clinical trials were undertaken as an international multicentre study by nine cleft teams in five countries. Three different surgical protocols for primary palate repair (Arm B-Lip and soft palate closure at 3-4 months, hard palate closure at 36 months, Arm C-Lip closure at 3-4 months, hard and soft palate closure at 12 months, and Arm D-Lip closure at 3-4 months combined with a single-layer closure of the hard palate using a vomer flap, soft palate closure at 12 months) were tested against a common procedure (Arm A-Lip and soft palate closure at 3-4 months followed by hard palate closure at 12 months) in the total cohort of 431 children born with a non-syndromic UCLP. Speech audio and video recordings of 399 children were available and perceptually analysed. Percentage of consonants correct (PCC) from a naming test, an overall rating of velopharyngeal competence (VPC) (VPC-Rate), and a composite measure (VPC-Sum) were reported.

OUTCOMES & RESULTS

The mean levels of consonant proficiency (PCC score) in the trial arms were 86-92% and between 58% and 83% of the children had VPC (VPC-Sum). Only 50-73% of the participants had a consonant proficiency level with their peers. Girls performed better throughout. Long delay of the hard palate repair (Arm B) indicated lower PCC and simultaneous hard and soft palate closure higher (Arm C). However, the proportion of participants with primary VPC (not including velopharyngeal surgeries) was highest in Arm B (68%) and lowest in Arm C (47%).

CONCLUSIONS & IMPLICATIONS

The speech outcome in terms of PCC and VPC was low across the trials. The different protocols had their pros and cons and there is no obvious evidence to recommend any of the protocols as superior. Aspects other than primary surgical method, such as time after velopharyngeal surgery, surgical experience, hearing level, language difficulties and speech therapy, need to be thoroughly reviewed for a better understanding of what has affected speech outcome at 10 years.

WHAT THIS PAPER ADDS

What is already known on the subject Speech outcomes at 10 years of age in children treated for UCLP are sparse and contradictory. Previous studies have examined speech outcomes and the relationship with surgical intervention in 5-year-olds. What this study adds to the existing knowledge Speech outcomes based on standardized assessment in a large group of 10-year-old children born with UCLP and surgically treated according to different protocols are presented. While speech therapy had been provided, a large proportion of the children across treatment protocols still needed further speech therapy. What are the potential or actual clinical implications of this work? Aspects other than surgery and speech function might add to the understanding of what affects speech outcome. Effective speech therapy should be available for children in addition to primary surgical repair of the cleft and secondary surgeries if needed.

Speech Symptoms of Velopharyngeal Insufficiency and the Incidence of Secondary Speech Surgery in 10-Year-Old Children With Unilateral Cleft Lip and Palate: Comparison of 2 Randomized Surgical Methods for Primary Palatal Surgery

OBJECTIVE

To compare speech symptoms of velopharyngeal insufficiency (VPI) and incidence of secondary speech surgery in 10-year-old Finnish children with unilateral cleft lip and palate (UCLP) following primary palatal surgery using 2 surgical methods.

DESIGN

Single center analysis within the Scandcleft multicenter randomized controlled trial of primary surgery for UCLP.

MATERIALS AND METHODS

Patients comprised 79 nonsyndromic 10-year-old children with UCLP. Two randomized surgical methods were used in the primary palatal surgery: soft palate closure at 4 months and hard palate closure at 12 months (Arm A) and closure of both the soft and hard palate at 12 months (Arm C). Speech symptoms of VPI were analyzed from standardized video recordings by 2 experienced speech pathologists. The incidences of surgery for correcting VPI, fistula closure, and speech therapy were evaluated retrospectively from patient records.

RESULTS

No differences in speech symptoms of VPI, need for VPI surgery or speech therapy were found between the surgical methods. Of all 79 children, 33% had had VPI surgery and 61% had speech therapy. The number of fistulas was significantly higher in Arm A (25%) than in Arm C (2%). Moderate to severe speech symptoms of VPI (hypernasality, continuous nasal air leakage, weak pressure consonants, and/or compensatory articulation) were found in 11% of the children.

CONCLUSION

No differences were present between groups in speech symptoms of VPI or need for VPI surgery or speech therapy between the 2 surgical methods. One third of the children had undergone VPI surgery. Most of the children (89%) had good or relatively good speech.

Adapting Elements of Cleft Care Protocols in Low- and Middle-income Countries During and After COVID-19: A Process-driven Review With Recommendations

A consortium of global cleft professionals, predominantly from low- and middle-income countries, identified adaptations to cleft care protocols during and after COVID-19 as a priority learning area of need.

A multidisciplinary international working group met on a videoconferencing platform in a multi-staged process to make consensus recommendations for adaptations to cleft protocols within resource-constrained settings. Feedback was sought from a roundtable discussion forum and global organizations involved in comprehensive cleft care.

Foundational principles were agreed to enable recommendations to be globally relevant and two areas of focus within the specified topic were identified. First the safety aspects of cleft surgery protocols were scrutinized and COVID-19 adaptations, specifically in the pre- and perioperative periods, were highlighted. Second, surgical procedures and cleft care services were prioritized according to their relationship to functional outcomes and time-sensitivity. The surgical procedures assigned the highest priority were emergent interventions for breathing and nutritional requirements and primary palatoplasty. The cleft care services assigned the highest priority were new-born assessments, pediatric support for children with syndromes, management of acute dental or auditory infections and speech pathology intervention.

A collaborative, interdisciplinary and international working group delivered consensus recommendations to assist with the provision of cleft care in low- and middle-income countries. At a time of global cleft care delays due to COVID-19, a united approach amongst global cleft care providers will be advantageous to advocate for children born with cleft lip and palate in resource-constrained settings.

The impact of hearing loss on speech outcomes in 5-year-old children with cleft palate ± lip: A longitudinal cohort study

OBJECTIVES

To investigate the impact of hearing loss (using longitudinal measurements of hearing) on speech outcomes at age 5 (5 years 0 months-5 years 11 months) in children born with cleft palate ± lip. Other variables which may impact upon the speech outcomes at age 5 in this population were also investigated.

METHODS

A retrospective longitudinal cohort study of children, without a named syndrome, born with cleft palate ± lip, and treated at a Cleft Centre in the United Kingdom. Data collected from infancy to 5 years 11 months, included hearing test results from three specific time points (7 months-1 year 2 months [age A]; 2 years 0 months-2 years 11 months [age B]; 5 years 0 months-5 years 11 months [age C]) and speech outcome data at age 5 years (5 years 0 months-5 years 11 months). Hearing test results at each age were compared to identify how hearing changes with age. Correlations between hearing test results and speech outcomes at age 5 were analysed.

RESULTS

Hearing loss was frequent but predominantly mild. There were no significant correlations between speech outcomes and hearing results at any age. Mild hearing loss remained prevalent at age 5, although a significant age-related hearing improvement was found. A significant relationship between cleft type and cleft speech characteristics was found (P < .001); children with Bilateral Cleft Lip and Palate achieved the poorest articulation outcomes.

CONCLUSION

Although mild hearing loss was common in the cohort, there was no association between hearing loss and the speech outcomes investigated. In contrast, the type of cleft was significantly associated with the presence of cleft speech characteristics. Further longitudinal measurement of hearing is required to substantiate the findings of this study.

Speech Outcome and Self-Reported Communicative Ability in Young Adults Born With Unilateral Cleft Lip and Palate: Comparing Long-Term Results After 2 Different Surgical Methods for Palatal Repair

OBJECTIVE

To compare speech outcome and self-reported speech and communicative ability (SOK) in young adults treated with one-stage (OS) or two-stage (TS) palatal repair. Furthermore, to compare with normative data on individuals without cleft lip and palate and to study the relationship between patients' and experts' judgments.

DESIGN

A cross-sectional group comparison study with long-term follow-up. Participants: Patients born with unilateral cleft lip and palate treated at 2 cleft centers; 17 with OS at 14 months and 25 with TS, soft palate repair at 7 months and hard palate repair at 6.2 years. Pharyngeal flap surgery was performed in 53% (OS) and 24% (TS) of patients.

MAIN OUTCOME MEASURE(S)

Speech characteristics were blindly assessed by speech and language pathologist from audio recordings, SOK at 19 years of age.

RESULTS

No group differences were found. Although the occurrence of nasality symptoms was low in both groups, only 60% (OS)/65% (TS) were assessed with competent velopharyngeal function (VPC). Articulation proficiency (percentage of consonants correct [PCC]) was 91%/97%, the /s/-sound specifically 87%/91%. Good intelligibility was found in 91%/87%. Patient opinion was in agreement with norms and significantly associated with intelligibility (rs = 0.436, P < .01), PCC (rs = -0.534, P < .01), and correct /s/ (rs = -0.354, P < .05).

CONCLUSIONS

No differences in speech outcome were related to operation method. The low prevalence of VPC was not clearly reflected in nasality symptoms. Patient opinion was related to articulation and intelligibility. A higher burden of care in terms of pharyngeal flap surgery was seen after the OS technique.

Speech in a consecutive series of children born with cleft lip and palate with and without syndromes and/or additional malformations

Background

When evaluating speech in children with cleft palate with or without cleft lip (CP/L), children with known syndromes and/or additional malformations (CP/L+) are usually excluded. The aim of this study was to present speech outcome of a consecutive series of 5-year-olds born with CP/L, and to compare speech results of children with CP/L + and children with CP/L without known syndromes and/or additional malformations (CP/L-).

Methods

One hundred 5-year-olds (20 with CP/L+; 80 with CP/L-) participated. All children were treated with primary palatal surgery in one stage with the same procedure for muscle reconstruction. Three independent judges performed phonetic transcriptions and rated perceived velopharyngeal competence from audio recordings. Based on phonetic transcriptions, percent consonants correct (PCC) and percent non-oral errors were investigated. Group comparisons were performed.

Results

In the total group, mean PCC was 88.2 and mean percent non-oral errors 1.5. The group with bilateral cleft lip and palate (BCLP) had poorer results on both measures compared to groups with other cleft types. The average results of PCC and percent non-oral errors in the CP/L + group indicated somewhat poorer speech, but no significant differences were observed. In the CP/L + group, 25 % were judged as having incompetent velopharyngeal competence, compared to 15 % in the CP/L- group.

Conclusions

The results indicated relatively good speech compared to speech of children with CP/L in previous studies. Speech was poorer in many children with more extensive clefts. No significant differences in speech outcomes were observed between CP/L + and CP/L- groups.

Speech input processing in children born with cleft palate: A systematic literature review with narrative synthesis

BACKGROUND

Speech development requires intact and adequately functioning oral anatomy and cognitive 'speech processing' skills. There is evidence that speech input processing skills are associated with speech output problems in children not born with a cleft. Children born with cleft palate ± lip (CP±L) are at high risk of developing disordered speech output. Less is known about their speech input processing skills and whether they are associated with cleft-related speech sound disorder (SSD).

AIMS

(1) To collate and evaluate studies reporting evidence regarding the speech input processing skills of children born with cleft palate in comparison with data from typically developing children or other comparison groups; and (2) to identify any available evidence regarding relationships between speech input processing skills and speech output in children born with CP±L.

METHODS & PROCEDURES

Potentially relevant studies published up to November 2019 were identified from the following databases: Medline via Ovid, Embase via Ovid, Cinahl via Ebscohost, PsycInfo via Ebscohost, BNI via ProQuest, AMED via Ovid, Cochrane Library and Scopus. Inclusion criteria were: peer-reviewed articles published in scientific journals, any design, published in English, participants born with a CP±L aged up to age 18 years who completed speech input processing assessments compared with normative data and/or a control or other comparison group. Critical Appraisal Skills Programme (CASP) checklists were used to quality appraise included studies.

OUTCOMES & RESULTS

Six studies were retained in the final review. There is some evidence that children born with CP±L perform less well than non-cleft controls on some speech input processing tasks and that specific input processing skills may be related to errors in the children's speech. Heterogeneity in relation to study groups and assessments used, as well as small sample sizes, limits generalization of findings.

CONCLUSION & IMPLICATIONS

There is limited evidence regarding the speech input processing skills of children born with CP±L. There are indications that children born with CP+/L may have difficulty in some aspects of speech input processing in comparison with children not born with a cleft, and that difficulties with some speech input processing tasks may be specific to errors in children's speech output. Further research is required to develop our understanding of these skills in this population and any associations with speech output.

WHAT THIS PAPER ADDS

What is already known on the subject Few studies have been published that examine aspects of speech input processing in children born with CP±L. Theoretical models of speech processing, and published studies, propose that speech input processing skills are associated with SSD in children who were not born with a cleft. However, it is less clear whether there is any association between speech input processing and cleft-related SSD. What this paper adds to existing knowledge This review systematically collates and evaluates the published, peer-reviewed evidence regarding speech input processing skills in children born with CP±L. The collated evidence indicates that some speech input processing skills differ between children with and without CP±L. There is some evidence, from a single study, that speech input processing of specific cleft speech characteristics (CSCs) may be associated with the presence of these CSCs in the speech output of some children born with CP±L. What are the potential or actual clinical implications of this work? While the evidence is currently limited, increasing our knowledge of speech input processing skills in children born with CP±L contributes to our clinical understanding of the nature of cleft-related SSD. The current evidence suggests that speech and language therapists should consider speech input processing skills when assessing children with cleft-related SSD to support intervention planning. Considering these skills in relation to literacy development in these children may also be important.

Identifying associations between dental arch relationship scores, relative deprivation and other cleft audit outcomes. Part 1

OBJECTIVES

To assess whether dental arch relationship scores are associated with speech, audiological and psychology outcomes in patients with complete unilateral cleft lip and palate (UCLP) and bilateral cleft lip and palate (BCLP).

SETTING AND SAMPLE POPULATION

One hundred 5-year-old children with non-syndromic complete UCLP and forty-two 5-year-olds with non-syndromic complete BCLP from the United Kingdom.

MATERIAL AND METHODS

Data were collected from five-year audit clinics for dental arch relationships, speech, hearing and psychology outcomes. Associations were assessed between ordinal prognostic covariates and the dental arch relationship outcome using a Cochrane-Armitage test for trend and comparisons with binary prognostic covariates using chi-square/Fisher's exact test. This was extended to assess associations between five-year audit outcomes and a measure of deprivation.

RESULTS

There was no evidence of associations between dental arch relationships and outcomes for audiology and speech. Individual domain analysis of the psychology outcomes within the UCLP cohort reported a poor outcome for Pro-social score to be associated with a poor 5-year-old index score (P = .018). For the BCLP sample, a good outcome for the BCLP Deciduous Dentition Yardstick was associated with a good conduct score (P = .01).

CONCLUSION

There was no association with the 5-year-old index/BCLP Deciduous Dentition Yardstick score and outcomes reported for audiology and speech. For the UCLP and BCLP cohorts, a poor dental arch relationship outcome may be associated with issues with some aspects of psychological well-being, associated with peer interactions and conduct. The deprivation index of samples had no association with the outcomes assessed.

Perceptual Speech Outcomes After Early Primary Palatal Repair in Ugandan Patients With Cleft Palate

OBJECTIVE

To provide speech outcomes of English-speaking Ugandan patients with a cleft palate with or without cleft lip (CP±L).

DESIGN

Prospective case-control study.

SETTING

Referral hospital for patients with cleft lip and palate in Uganda.

PARTICIPANTS

Twenty-four English-speaking Ugandan children with a CP±L (15 boys, 9 girls, mean 8.4 years) who received palatal closure prior to 6 months of age and an age- and gender-matched control group of Ugandan children without cleft palate.

INTERVENTIONS

Comparison of speech outcomes of the patient and control group.

MAIN OUTCOME MEASURES

Perceptual speech outcomes including articulation, resonance, speech understandability and acceptability, and velopharyngeal composite score (VPC-sum). Information regarding speech therapy, fistula rate, and secondary surgery.

RESULTS

Normal speech understandability was observed in 42% of the patients, and 38% were judged with normal speech acceptability. Only 16% showed compensatory articulation. Acceptable resonance was found in 71%, and 75% of the patients were judged perceptually to present with competent velopharyngeal function based on the VPC-sum. Additional speech intervention was recommended in 25% of the patients. Statistically significant differences for all these variables were still observed with the control children (P < .05).

CONCLUSIONS

Overall, acceptable speech outcomes were found after early primary palatal closure. Comparable or even better results were found in comparison with international benchmarks, especially regarding the presence of compensatory articulation. Whether this approach is transferable to Western countries is the subject for further research.

The Method of Surgical Lip Repair Affects Speech Outcomes in Children With Bilateral Cleft Lip and Palate

OBJECTIVE

It was hypothesized that lip repair protocols in children with bilateral cleft lip and palate (BCLP) would affect development of bilabial consonants /m/ /b/ /p/. This study compared speech outcomes in 2 surgical groups.

DESIGN

A retrospective case note investigation.

SETTING

UK Cleft Centre (2000-2009).

PATIENTS

Forty-nine children with complete BCLP, of whom 26 had a 1-stage and 23 a 2-stage bilateral cleft lip repair.

INTERVENTIONS

One-stage cleft lip repair versus a 2-staged cleft lip repair.

MAIN OUTCOME MEASURES

Bilabial consonant production at 18 months, 3 and 5 years of age. Cleft Speech Characteristics (CSCs) at age 5.

RESULTS

At age 18 months, 81% of the 1-stage lip repair group and 4% of the 2-stage lip repair group produced bilabial consonants (P <·0001, Fisher test). At age 3 years, 81% of the 1-stage and 26% of the 2-stage lip repair groups produced bilabial consonants (P =·0133, Fisher test). At age 5 years, both groups had similar bilabial consonant production, but children in the 2-stage lip repair group had more frequent and severe CSCs (P = ·0037, χ²).

CONCLUSION

A 1-stage lip repair for children with complete BCLP resulted in better bilabial consonant production at 18 months and 3 years of age than a 2-stage lip repair. At age 5 years both groups had bilabial consonants but children in the 2-stage lip repair group had worse CSCs. The surgical protocol for bilateral cleft lip repair affected speech outcome in children with BCLP.

Randomized controlled trial comparing Parent Led Therapist Supervised Articulation Therapy (PLAT) with routine intervention for children with speech disorders associated with cleft palate

BACKGROUND

A total of 68% of pre-school children with cleft palate have speech problems requiring speech therapy. There is a lack of access to regular targeted therapy. Parent training leads to positive outcomes in early communication skills in cleft palate and non-cleft speech disorders. Connected health has been used to address inadequate access to therapy, providing intervention to those who would not otherwise receive therapy.

AIMS

To evaluate the speech, activity and participation outcomes of Parent Led, Therapist Supervised, Articulation Therapy (PLAT) compared with routine speech therapy intervention in parent-child dyads.

METHODS & PROCEDURES

A total of 44 children, aged 2.9-7.5 years, were included in a two-centre, two-phase randomized controlled trial. Informed consent and assent were obtained. Participants and speech and language therapists (SLTs) were unblinded to the groups. Parents, in the parent-trained group (n = 23), attended 2 days' training, received a detailed speech therapy programme, and undertook intervention over 12 weeks supported by the cleft specialist SLT using FaceTime and one face-to-face session. In the control arm (n = 21), parent-child dyads received six therapy sessions over 12 weeks with a research SLT, comparable with usual care. Speech recordings were undertaken pre- and post-intervention. Percent consonant correct (PCC) was analysed by external SLTs blinded to the time and group. Activity and participation were measured using the Intelligibility in Context Scale (ICS) and Focus on Outcomes for Children Under Six (FOCUS) questionnaire.

OUTCOMES & RESULTS

There was no evidence of an interaction between Time and Group or an overall statistical difference between groups for PCC scores. There was a statistically significant difference over time for both groups (words: p < 0.002; confidence interval (CI) = 9.38-16.27; d = 0.57; sentences: p < 0.002; CI = 16.04-25.97; d = 0.23). Effect sizes were medium for words and small for sentences. For intelligibility and participation, there was no evidence of an interaction between Time and Group or an overall statistical difference between groups. A statistically significant difference over time was found for intelligibility (F = 29.97, d.f. = 1, 42, p < 0.001, 95 % CI = 1.45-3.15 d = 0.46) and for participation (F = 14.19, d.f. = 1, 41, p < 0.001 95% CI = 7.63-25.03; d = 0.36) with FOCUS results indicating clinically meaningful (parent-led group) and significant (control group) change in participation.

CONCLUSIONS & IMPLICATIONS

PLAT can be as effective as routine care in changing speech, activity and participation outcomes for children with cleft palate, when supported by a specialist cleft SLT using connected health. What this paper adds What is already known on this subject Over 50% of children with cleft palate require speech therapy. However, there is a lack of timely, accessible speech therapy services in the UK and Ireland. Previous studies have shown that parents can deliver therapy effectively, and that connected health can support the delivery of speech therapy. This study aims to provide evidence that parent-led therapy with the supervision of a specialist cleft therapist using FaceTime is effective. What this paper adds to existing knowledge This randomized controlled trial indicates that parents can be trained to deliver therapy for children with cleft palate speech disorders, under the supervision of an SLT. This approach results in improved speech, activity and participation outcomes similar to routine care. What are the potential or actual clinical implications of this work? This study indicates that both parent-led articulation therapy and routine care showed meaningful gains in speech, activity and participation, and that parent-led articulation therapy when supported by a cleft SLT using connected health could be an additional service delivery model for children with cleft palate speech disorders.

Benchmarking Speech, Velopharyngeal Function Outcomes and Surgical Characteristics Following the Sommerlad Protocol and Palate Repair Technique

Objective:

To report speech and velopharyngeal function (VPF) outcomes, and surgical characteristics, at age 5 following early complete palate closure using the Sommerlad protocol.

Design:

A retrospective, descriptive, cross-sectional consecutive series.

Setting:

A regional twin site center; a district general hospital and tertiary children’s hospital.

Participants:

Between 1993 and 2006, 877 participants underwent surgery; 712 (81%) were eligible for inclusion; 391 (55%) were included, 321 (45%) excluded. Thirteen percent had bilateral cleft lip and palate (CLP), 40% unilateral CLP, and 47% isolated cleft palate.

Intervention:

Lip and vomerine flap repair at 3 months of age (BCLP, UCLP) with soft palate closure using radical muscle dissection and retropositioning at a mean age of 6.6 months, range 4 to 23 months, as described and undertaken by Sommerlad.

Outcome Measures:

Velopharyngeal Composite (VPC) CAPS-A and articulation summary scores derived from analysis using the Cleft Audit Protocol for Speech-Augmented.

Results:

A VPC-SUM CAPS-A score of “0” was found in 97% reflecting adequate VPF; 73% had no cleft articulation difficulties. The BCLP group had the poorest articulation. Secondary speech surgery rate was 2.6% and 10.7% had fistula repair. Levator muscle quality and degree of retropositioning was associated with speech outcomes related to VPF. 2.6% had current features of VPI.

Conclusions:

Complete palate closure by around 6 months of age by the surgeon who described the technique led to excellent perceived VPF and very good speech outcomes at age 5, with less speech therapy and secondary speech surgery than commonly reported. These findings serve as a benchmark for the Sommerlad protocol and technique.

Internationally Adopted Children With Unilateral Cleft Lip and Palate-Consonant Proficiency and Perceived Velopharyngeal Competence at the Age of 5

OBJECTIVE

To compare consonant proficiency, consonant errors, and the perceived velopharyngeal (VP) competence in internationally adopted (IA) children with unilateral cleft lip and palate (UCLP) and nonadopted (NA) children with the same cleft-palate type at age 5.

DESIGN

Case-control study based on phonetic transcriptions of standardized speech recordings of 5-year-olds at a tertiary hospital.

PARTICIPANTS

Twenty-five IA children were compared to 20 NA children. All consecutive patients at a cleft lip and palate center participated.

MAIN OUTCOME MEASURE(S)

Consonant proficiency was measured using percentage consonants correct, percentage consonants correct-adjusted for age, percentage correct place, percentage correct manner, and consonant inventory. Cleft speech characteristics (CSCs), developmental speech characteristics (DSCs), and the perceived VP competence were also measured.

RESULTS

The IA children had significantly lower values for all consonant proficiency variables (p < .05) and a smaller consonant inventory (p = .001) compared to the NA children. The IA children had a higher frequency of CSCs (IA = 84%, NA = 50%, p < .05) and DSCs (IA = 92%, NA = 65%, p = .057), and twice as many IA children as NA children had perceived VP incompetence (IA = 52%, NA = 25%, p = .17).

CONCLUSIONS

Severe speech disorder was more common in IA children than in NA children at age 5. Most importantly, the speech disorders seem to be not only cleft-related. More detailed speech assessments with a broader focus are needed for IA children with UCLP. Longitudinal studies are recommended to further investigate the impact of speech difficulties in IA children's daily lives.

Scandcleft Project Trial 3: Comparison of Speech Outcomes in Relation to Sequence in 2-Stage Palatal Repair Procedures in 5-Year-Olds With Unilateral Cleft Lip and Palate

OBJECTIVE

To compare speech outcome following different sequencing of hard and soft palate closure between arms and centers within trial 3 and compare results to peers without cleft palate.

DESIGN

A prospective randomized clinical trial.

SETTING

Two Norwegian and 2 British centers.

PARTICIPANTS

One hundred thirty-six 5-year-olds with unilateral cleft lip and palate were randomized to either lip and soft palate closure at 3 to 4 months and hard palate closure at 12 months (arm A) or lip and hard palate closure at 3 to 4 months and soft palate closure at 12 months (arm D).

MAIN OUTCOME MEASURES

A composite measure of velopharyngeal competence (VPC), overall assessment of VPC from connected speech (VPC-Rate). Percentage of consonants correct (PCC), active cleft speech characteristics (CSCs), subdivided by oral retracted and nonoral errors, and developmental speech characteristics (DSCs).

RESULTS

Across the trial, 47% had VPC, with no statistically significant difference between arms within or across centers. Thirty-eight percent achieved a PCC score of >90%, with no difference between arms or centers. In one center, significantly more children in arm A produced ≥3 active CSCs (P < .05). Across centers, there was a statistically significant difference in active CSCs (arm D), oral retracted CSCs (arm D), and DSCs (arms A and D).

CONCLUSIONS

Less than half of the 5-year-olds achieved VPC and around one-third achieved age-appropriate PCC scores. Cleft speech characteristics were more common in arm A, but outcomes varied within and across centers. Thus, outcome of the same surgical method can vary substantially across centers.

Hearing Thresholds in Young Children With Otitis Media With Effusion With and Without Cleft Palate

Objective:

To investigate hearing thresholds in children born with cleft palate and in children with otitis media with effusion but no cleft palate.

Design:

Prospective longitudinal group comparison study.

Setting:

University hospital.

Participants:

Sixteen children born with nonsyndromic cleft palate with or without cleft lip (CP±L) and 15 age-matched children with otitis media with effusion (OME) but without cleft.

Main Outcome Measures:

Hearing was tested at repeated occasions beginning with neonatal auditory brainstem response (ABR) at 1-4 months of age, and age-appropriate hearing tests from 9 to 36 months of age.

Results:

The median ABR thresholds in both groups were elevated but did not differ significantly. At 12 months of age, the median 4 frequency averages at 500-1000-2000-4000 Hz (4FA) were indicative of mild hearing loss but significantly better in the CP±L-group than in the group without cleft ( P < .01). There were no significant group-wise differences regarding the median 4FA at 24 and 36 months of age, and at 36 months, the median 4FA were normal in both groups. Both groups exhibited a significant improvement over time from the neonatal ABR thresholds to the 4FA at 36 months (CP±L-group P < .05; without CP±L-group P < .01).

Conclusion:

The hearing loss in children with CP±L was not more severe than among children with OME but without cleft palate; rather, at 12 months of age, the thresholds were significantly better in the CP±L-group than those in the group without cleft. The air conduction thresholds improved with age in both groups.

Scandcleft Project Trial 2-Comparison of Speech Outcome in 1- and 2-Stage Palatal Closure in 5-Year-Olds With UCLP

OBJECTIVE

To investigate in-depth speech results in the Scandcleft Trial 2 with comparisons between surgical protocols and centers and with benchmarks from peers without cleft palate.

DESIGN

A prospective randomized clinical trial.

SETTING

Two Swedish and one Finnish Cleft Palate center.

PARTICIPANTS

One hundred twelve participants were 5-years-old born with unilateral cleft lip and palate randomized to either lip repair and soft palate closure at 4 months and hard palate closure at 12 months or lip repair at 3 to 4 months (Arm A), or a closure of both the soft and hard palate at 12 months (Arm C).

MAIN OUTCOME MEASURES

A composite measure dichotomized into velopharyngeal competency (VPC) or velopharyngeal incompetency (VPI), overall assessment of velopharyngeal function (VPC-Rate), percentage of consonants correct (PCC score), and consonant errors. In addition, number of speech therapy visits, average hearing thresholds, and secondary surgeries were documented to assess burden of treatment.

RESULTS

Across the trial, 53.5% demonstrated VPC and 46.5% VPI with no significant differences between arms or centers. In total, 27% reached age-appropriate PCC scores with no statistically significant difference between the arms. The Finnish center had significantly higher PCC scores, the Swedish centers had higher percentages of oral consonant errors. Number of speech therapy visits was significantly higher in the Finnish center.

CONCLUSION

At age 5, poor speech outcomes with some differences between participating centers were seen but could not be attributed to surgical protocol. As one center had very few participants, the results from that center should be interpreted with caution.

Stages in the Development and Validation of a Belgian Dutch Outcome Tool for the Perceptual Evaluation of Speech in Patients With Cleft Palate

Objective:

To develop and validate a Belgian Dutch outcome tool for the perceptual evaluation of speech in patients with cleft palate.

Setting:

Cleft palate team in a tertiary university hospital.

Methods:

The tool was based on the Cleft Audit Protocol for Speech–Augmented (John et al., 2006; Sell et al., 2009), with adaptations to some of the speech variables and the structured listening protocol. Following a preliminary listening experiment in phase 1, the tool was optimized. In the second phase, a listening experiment with 4 experienced listeners was set up to assess face validity, inter- and intrarater reliability and criterion validity.

Results:

Results of phase 1 indicated good to very good inter- and intrarater reliability for the majority of the speech variables, good discriminant validity, and varying sensitivity and specificity based on a comparison with nasalance values and the Nasality Severity Index 2.0 (criterion validity). Results of phase 2 showed good to very good interrater reliability for 5 of the 14 variables and good intrarater reliability in 3 of the 4 experienced listeners. Sensitivity and specificity were sufficient, except the specificity of the hypernasality judgments in comparison with the nasalance values of the oral text. Overall, listeners positively judged the face validity of the tool.

Conclusion:

The 2-phase evaluation indicated varying validity and reliability results. Future studies will aim to optimize validity and reliability of the developed tool based on adaptations to the listening protocol, the addition of speech variables, and the inclusion of a more elaborate training.

Scandcleft Project, Trial 1: Comparison of Speech Outcome in Relation to Timing of Hard Palate Closure in 5-Year-Olds With UCLP

OBJECTIVE

To compare in-depth speech results in Scandcleft Trial 1 as well as reference data from peers without cleft palate (CP).

DESIGN

A prospective randomized clinical trial.

SETTING

A Danish and a Swedish CP center.

PARTICIPANTS

143 of 148 randomized 5-year-olds with unilateral cleft lip and palate. All received lip and velum closure at 4 months, and hard palate closure at 12 months (arm A) or 36 months (arm B).

MAIN OUTCOME MEASURES

A composite measure based on velopharyngeal competence (VPC) or velopharyngeal incompetence (VPI), an overall assessment of VPC from connected speech (VPC-Rate), Percentage of Consonants Correct (PCC-score), and consonant errors. Speech therapy visits, average hearing thresholds, and secondary pharyngeal surgeries documented burden of treatment.

RESULTS

Across the trial, 61.5% demonstrated VPC and 38.5% VPI. Twenty-two percent of participants achieved age appropriate PCC-scores. There were no statistically significant differences between arms or centers for these measures. In the Danish center, arm B: achieved lower PCC-scores (P = .01); obtained PCC-scores without s-errors below 79% (P = .002); produced ≥3 active oral cleft speech characteristics (P = .004) than arm A. In both centers, arm B attended more speech visits.

CONCLUSIONS

At age 5, differences between centers and treatment arms were not statistically significant for VPC/VPI, but consonant proficiency differed between treatment arms in the Danish center. Poor speech outcomes were seen for both treatment arms. Variations between centers were observed. As the Swedish center had few participants, intercenter comparisons should be interpreted with caution.

The relationship between health-related quality of life and speech in patients with cleft palate

INTRODUCTION

In health-care, current efforts focus on providing patient-centered care. Specifically for patients with velopharyngeal insufficiency, and by extent patients with cleft palate, the Velopharyngeal Insufficiency (VPI) Effects on Life Outcomes (VELO) questionnaire (Skirko et al., 2012; 2013) allows the clinician to map the impact of speech and swallowing difficulties on the patient's health-related quality of life (HRQoL). The current study evaluated the hypothesized association between this speech-related HRQoL measure and perceptually and instrumentally assessed speech variables, to provide evidence for the construct validity of the Dutch version of the VELO questionnaire.

MATERIALS AND METHODS

Thirty participants, twenty-five patients with cleft palate and five controls, were enrolled. Perceptual speech assessment was conducted following the recently developed Belgian Dutch outcome tool for perceptual speech assessment in patients with cleft palate. In addition, nasalance values and the Nasality Severity Index (NSI) 2.0 were determined. The relationship between these speech outcomes and the scores on the VELO parent report was determined using Spearman rank-order correlation coefficients.

RESULTS

Moderate to strong correlations were found between the total score on the VELO parent report and five speech variables: the VPC-SUM score (r_s = -0.476), speech understandability (r_s = -0.657), passive CSC's (r_s = -0.654), speech acceptability (r_s = -0.591) and the need for C(L)P-related speech therapy (r_s = -0.711). Furthermore, these variables were associated with at least one subscale of the VELO questionnaire.

DISCUSSION AND CONCLUSION

Correlations between speech outcomes and the Dutch version of the VELO questionnaire provide evidence for the construct validity of this version of the instrument. Furthermore, insights in these associations may lead the way to efficient therapy approaches, targeting speech features with the greatest impact on the patient's health-related quality of life.

Orofacial myofunctional evaluation in cleft lip and palate: an integrative literature review

ABSTRACT Purpose: to identify the focus of scientific publications in the field of orofacial motricity in individuals with cleft lip and palate, as well as validated protocols used in speech and language evaluation. Methods: a study conducted using the following databases: Medline, SciELO, Lilacs and Google Scholar, through keywords including: cleft palate + cleft lip + evaluation + speech therapy + stomatognathic system + speech + phonation + chewing + swallowing + breathing + validation studies, in Portuguese and English. Results: a total of 572 articles that addressed the evaluation of the stomatognathic system was selected. The articles were published between 2012 and 2017, and examined for year of publication, subject area, focus, instrument used for evaluation, and type of study. Of these, 90 articles met the inclusion criteria, but only 5 used validated protocols. The greatest number of articles was published in 2014. The studies covered broad age groups, using subjective and objective methods, and instruments were often non-standardized. Conclusion: speech was the prevalent theme, while other orofacial functions were poorly investigated, demonstrating that studies with other approaches were lacking.

Centre-level variation of treatment and outcome in 5-year-old children with non-syndromic unilateral cleft lip and palate: The Cleft Care UK study. Part 1: Methodology and results for dento-facial outcomes

OBJECTIVES

Outline methods used to describe centre-level variation in treatment and outcome in children in the Cleft Care UK (CCUK) study. Report centre-level variation in dento-facial outcomes.

SETTING AND SAMPLE POPULATION

Two hundred and sixty-eight five-year-old British children with non-syndromic unilateral cleft lip and palate (UCLP).

MATERIALS AND METHODS

Between January 2011 and December 2012, data were collected on a comprehensive range of outcomes. Child facial appearance and symmetry were assessed using photographic pictures. Dental arch relationships were assessed from standardized dental study models. Hierarchical statistical models were used to predict overall means and the variance partition coefficient (VPC)-a measure of amount of variation in treatment or outcome explained by the centre.

RESULTS

Data on dento-alveolar arch relationships and facial appearance were available on 197 and 252 children, respectively. The median age of the children was 5.5 years, and 68% were boys. Variation was described across 13 centres. There was no evidence of centre-level variation in good or poor dento-alveolar arch relationships with a VPC of 4% and 3%, respectively. Similarly, there was no evidence of centre-level variation in good or poor facial appearance with a VPC of 2% and 5%, respectively.

CONCLUSIONS

There was no evidence of centre-level variation for dento-facial outcomes although this study only had the power to detect large variation between sites.

Centre-level variation in behaviour and the predictors of behaviour in 5-year-old children with non-syndromic unilateral cleft lip: The Cleft Care UK study. Part 5

OBJECTIVES

The aims of this study were to describe child behavioural and psychosocial outcomes associated with appearance and speech in the Cleft Care UK (CCUK) study. We also wanted to explore centre-level variation in child outcomes and investigate individual predictors of such outcomes.

SETTING AND SAMPLE POPULATION

Two hundred and sixty-eight five-year-old children with non-syndromic unilateral cleft lip and palate (UCLP) recruited to CCUK.

MATERIALS AND METHODS

Parents completed the Strengths and Difficulties questionnaire (SDQ) and reported their own perceptions of the child's self-confidence. Child facial appearance and symmetry were assessed using photographs, and intelligibility of speech was derived from audio-visual speech recordings. Centre-level variation in behavioural and psychosocial outcomes was examined using hierarchical models, and associations with clinical outcomes were examined using logit regression models.

RESULTS

Children with UCLP had a higher hyperactive difficulty score than the general population. For boys, the average score was 4.5 vs 4.1 (P=.03), and for girls, the average score was 3.8 vs 3.1 (P=.008). There was no evidence of centre-level variation for behaviour or parental perceptions of the child's self-confidence. There is no evidence of associations between self-confidence and SDQ scores and either facial appearance or behaviour.

CONCLUSIONS

Children born with UCLP have higher levels of behaviour problems than the general population.
