Evaluación perceptual de la insuficiencia velofaríngea en personas con fisura del paladar: una revisión integradora de literatura

La insuficiencia velofaríngea (IVF) secundaria de fisura del paladar corresponde al cierre incompleto del mecanismo velofaríngeo durante el habla, debido a una falta de tejido en el paladar blando o las paredes de la faringe, lo cual genera una resonancia hipernasal y una emisión nasal de aire en los sonidos orales. Al respecto, en la literatura existen diversas propuestas para la evaluación perceptual de la IVF. Por esto, el objetivo del presente estudio es describir la evaluación perceptiva auditiva de la insuficiencia velofaríngea, mediante una revisión integradora de literatura. Para ello, en mayo de 2020 las bases de datos electrónicas PUBMED, LILACS, SciELO y Cochrane, fueron consultadas utilizando las palabras claves en inglés: “Velopharyngeal Sphincter”, “Velopharyngeal Insufficiency”, “Cleft Palate”, “Speech Intelligibility”, “Speech Production Measurement”, “Speech Articulation Tests” y “Speech-Language Pathology” y sus respectivos equivalentes en portugués y español. Se seleccionaron artículos originales relacionados al tema, y se creó un protocolo específico para la extracción de los datos. En total se encontraron 2.385 artículos. De ellos, 2.354 fueron excluidos por el título, 13 por el resumen y 3 luego de la lectura del texto completo. Finalmente, a partir de la metodología desarrollada, en esta revisión fueron utilizados 33 artículos. A partir de la revisión realizada se concluye que los parámetros más utilizados en la evaluación son la hipernasalidad, la emisión nasal y la articulación compensatoria asociada a IVF. Estos parámetros son evaluados principalmente en oraciones, habla espontánea y palabras, por un fonoaudiólogo experto, en vivo y mediante grabaciones de audio.

Speech-aid prosthesis in velopharyngeal incompetency patient with cleft palate: can speech aids be applicable for adult patient?

Background Velopharyngeal incompetence (VPI) therapy for cleft palate (speech therapy alone, speech therapy using speech aids, or combined therapy such as speech therapy using a pharyngeal flap), is more effective in younger patients than in adult patients. Speech therapy is known as very difficult for patients who still have VPI as an adult. Because of the possibility of subsequent speech disorders, the timing of surgery for cleft palate is accelerating. Herein, we present a case of an adult with articulation disorder due to VPI who was treated by speech therapy and a speech-aid prosthesis. Case presentation A woman who underwent cleft palate surgery at 8 years of age still had difficulty with articulation due to VPI as a 24-year-old adult because of a lack of continuous speech therapy. We decided to use a speech-aid application using palatal lift, and a reduction program was conducted four times, along with simultaneous speech therapy, over a period of 1 year and 7 months. During the therapy period, she was able to speak normally within a relatively short period of time, and after implementation of the reduction program, the therapy was completed by completely removing the device. Long-term observations have shown normal speech function without recurrence, even after the device was removed. Conclusion As seen in this case, speech therapy using speech aids can show a good result for adult patients with cleft palate who missed the usual timing for the treatment of articulation disorders, depending on the situation. Therefore, it is hereby reported as a therapy option worthy of consideration.

Reliability of Outcome Measures to Assess Consonant Proficiency Following Cleft Palate Speech Intervention: The Percentage of Consonants Correct Metric and the Probe Scoring System

Purpose This study compared the inter- and intrarater reliability of the percentage of consonants correct (PCC) metrics and the probe scoring system between an experienced and a less experienced rater and between two experienced raters. In addition, these outcome measures' ability to reflect changes following speech intervention was measured. Method During Phase 1, two raters (Rater 1 with 5 years of experience in cleft-related speech disorders and Rater 2 with limited experience in cleft-related speech disorders) independently assessed 134 speech samples at the word and sentence levels, which were collected on different data points before, during, and following a cleft palate speech intervention. During Phase 2, a third rater (with 8 years of experience) analyzed 34 speech samples. The percentage of consonants correct–revised, the percentage of correct places and manners, and probe scores at the word and sentence levels were measured. Results Poor-to-moderate interreliability between Raters 1 and 2 was found due to differences in error classification. Interrater reliability between Raters 1 and 3 was very good for both the PCC metrics and the probe scores. The interrater reliability for the amount of targets elicited was lower compared to the interrater reliability for the amount of targets correct. The probe scoring system demonstrated a greater ability to detect changes toward the correct production of the target consonant compared to the PCC metrics. Conclusions Having an experience with the assessment of cleft-related speech disorders is a crucial factor to gain reliable results. The interrater reliability for the PCC metrics and the probe scoring system between two experienced raters did not differ, suggesting that both outcome measures can be used in cleft palate speech intervention studies. Despite the ability of the probe scoring system to detect changes, further research should provide insight in the benefits of this system both for research and clinical purposes.

English-Only Treatment of Compensatory Speech Errors in a Bilingual Adoptee With Repaired Cleft Palate: A Descriptive Case Study

Purpose The purpose of this clinical focus article is to provide a descriptive case study of a late-adopted, bilingual adolescent with cleft palate speech errors. Specifically, we examined the cross-linguistic generalization of remediated compensatory cleft errors, following treatment in English (second language) only. The overarching goal of this study is to gain insights into the complexity of speech intervention for the adopted population with delayed cleft palate repair. Method A 14-year-old female adopted from China with a repaired unilateral cleft lip and palate and maladaptive articulation errors underwent 55 one-hour sessions of a motor-based, speech therapy approach over a 15-month span, targeting English phonemes only. Pre-, mid-, and posttreatment evaluation included perceptual and instrumental assessment of speech and resonance. Outcome measures at each time point included perceptual speech and resonance ratings, nasometry scores, and percent consonants correct (PCC) in both English and Mandarin. Results PCC in English improved from 60% in single words and 35% in sentences pretreatment to 100% in single words and sentences during posttreatment assessment. Without direct treatment in Mandarin, PCC in Mandarin improved from 56% in single words and 50% in sentences pretreatment to 100% in single words and 99% in sentences during posttreatment assessment. Posttreatment nasometry scores decreased by 20% for the nasal sample and 17% for the oral sample compared to pretreatment. Conclusions This descriptive case study demonstrated successful remediation of cleft palate speech errors, following 15 months of treatment in a late-adopted bilingual adolescent using a motor-based therapy approach. Treatment of errors in English (second language) led to generalization of correct productions in Mandarin (first language). This study presents the potential for bilingual late adoptees to achieve intelligible speech in both languages when motor-based therapy principles are applied to intervention.

Applying the ICF-CY to Specialist Speech-Language Pathologists’ Practice With Toddlers With Cleft Palate Speech

Objective: To evaluate how the practice of specialist speech-language pathologists (SLPs) working with young children with cleft palate ± cleft lip (CP±L) maps onto the International Classification of Functioning, Disability, and Health – Children and Youth version (ICF-CY) and consider the functionality of the categories of the ICF-CY for this specialist area of practice. Design: Cross-sectional, qualitative study. Setting: Semistructured face-to-face interviews were conducted with SLPs working in tertiary-level hospitals, universities, and public clinics. Participants: Six specialist SLPs with 17 to 39 years of experience working with young children with CP±L as researchers and clinicians in Australia, Brazil, Denmark, Ireland, New Zealand, and the United States. Main Outcome Measure(s): Specialists’ practices were captured using in-depth, semistructured interviews. Data collected were analyzed by directed content analysis applying the ICF-CY as a coding schema. Results: In total, 4077 data points were coded. Most mapped onto Body Structures (684, 16.8%), Body Functions (906, 22.2%), and Environmental Factors (1626, 39.9%) with less emphasis on Activities and Participation (560, 13.7%). A “best fit” approach was taken to topics that did not map exactly onto categories of the ICF-CY (eg, velopharyngeal insufficiency [VPI]); however, there was not always an ideally suitable category available. Conclusions: The current study revealed strengths and challenges in categorizing practice within the ICF-CY for children with CP±L, including collaboration with parents and significant others, specificity around speech, language, and articulation, and the different types of VPI. Therefore, future discussion around how best to use the framework with children with CP±L is needed.
