Speech and Resonance Disorders in Children With Cleft Palate: Diagnostic Evaluation and Current Speech Therapy Modalities.

This article will provide an overview of how speech and resonance can be impacted in children with cleft palate. The authors will outline evidence-based assessment and treatment approaches commonly used for children with cleft palate and provide information on current initiatives to provide speech therapy. The methods discussed will be the use of telehealth to provide access to speech therapy for patients in areas without speech-language pathologists and the use of speech therapy camps to offer intensive, limited-duration speech therapy for groups of children due to the lack of trained providers in certain geographical regions.

Surgical and Speech Therapy Evaluation of Lingual Frenulum.

Interdisciplinary evaluation is essential to diagnose and define clinical conduct for children and adults presenting with an altered lingual frenulum; however, there are few reports on the subject in the literature. In this context, the following study exemplifies a proposed protocol for the surgical and SLT treatment of a lingual frenulum based on a review of the literature and the experience of speech and language therapists and maxillofacial surgeons from hospitals in Santiago de Chile. After its application, a history of breastfeeding with difficulties and a maintained preference for soft foods was reported. Upon anatomic examination, the lingual apex was heart-shaped, and the lingual frenulum was fixed in the upper third of the ventral side of the tongue, with a pointed shape, submerged up to the apex, and of adequate thickness. Meanwhile, upon functional examination, the tongue was descended at rest, performed tongue protrusion with restrictions (raising and clicking), did not achieve attachment or vibration, and presented distortion of the sounds / r/ and /rr/. With this information, an altered lingual frenulum was diagnosed, with the indication for surgery and postoperative speech and language therapy. The constructed instrument allowed for the standardization of the evaluation in different teams but should be validated in future research.

International Collaboration for the Prosthetic and Surgical Intervention of Velopharyngeal Insufficiency.

Interdisciplinary teamwork is essential for the rehabilitation of patients with cleft lip and palate, and therefore, the application of treatment techniques for velopharyngeal insufficiency, both surgical and prosthetic, depends on the experience of each rehabilitation team. For this reason, the following study consisting of the cooperation between interdisciplinary cleft lip and palate teams from Chile and Argentina, which succeeded in correcting velopharyngeal insufficiency in an adolescent, initially using a pharyngeal bulb prosthesis and speech therapy, and finally through pharyngeal flap surgery, is presented. This shows that international cooperation is a valuable tool for training, implementation, and follow-up of different treatment techniques for teams in formation.

Primary Palatal Surgery in Nonsyndromic Cleft Palate Children and Velopharyngeal Insufficiency Correction Outcomes.

ABSTRACT: Speech has a very significant impact on the life quality of people with cleft and lip palate. Restore tissue anatomy and functionality is the main aim of primary palatal surgery. Multiple factors are associated with successful handling, including the need for a velopharyngeal insufficiency (VPI) secondary surgery. The study's aim is to determine speech and velopharyngeal function outcomes in children with cleft palate operated in our institution and to determine VPI secondary surgery outcomes, if appropriate. Clinical records of nonsyndromic patients with cleft palate born between January 2009 and December 2012, who performed their multidisciplinary care on our institution, were analyzed retrospectively. One hundred forty-two patients received primary palatal surgery. Eighty (56%) were male and 62 (44%) female. Twenty-two had soft cleft palate, 9 hard and soft cleft palate, 84 unilateral, and 27 bilateral cleft lip and palate. Twelve percent of patients presented palatal fistula, with a significantly higher presentation in Soft Cleft Palate and Hard and Soft Cleft Palate. Twenty-seven patients (19%) had surgical indication for VPI correction, and 20 of them received VPI surgery, before school age. Cleft type and gender were significantly associated with VPI surgery indication rate. Postsurgery, 80% presented normal resonance. Nasal emission improved in 85% of patients. Nasometry decreased from 45% to 31%. Hyponasality increased by 10%. One case presented total flap dehiscence. Preoperative planning must be done carefully and individualized to succeed. Future prospective research that considers all the variables for a correct analysis is advisable, to improve our results.

22q11.2 Deletion: Surgical and Speech Outcomes of Patients With Velopharyngeal Insufficiency Treated With a Superiorly Based Pharyngeal Flap as the Primary Surgery.

The most frequent palate diagnoses in patients with chromosome 22q11.2 deletion syndrome are a classic submucous cleft, occult, and velopharyngeal insufficiency without cleft, which generates alterations in speech that require surgery. Surgical protocols are controversial owing to syndrome characteristics that make their handling more complex. Pharyngeal flap pharyngoplasty is effective for this type of patient. The objective of this study is to examine the surgical management of velopharyngeal insufficiency in patients with chromosome 22 deletion, using a pharyngeal flap as the primary surgery. The clinical records of patients with chromosome 22 deletion and velopharyngeal insufficiency between 2015 and 2017 were analyzed retrospectively. Eight patients underwent pharyngeal flap pharyngoplasty as a primary surgery, including 1 with velopharyngeal insufficiency without a cleft, 1 with a classic submucous cleft, and 6 with occult submucous cleft. The pre- and postoperative protocol performed by speech therapists and surgeons included clinical evaluation of the oral cavity; perceptual, video recording, and nasometry speech evaluation; and videonasopharyngoscopy. All perceptual parameters and nasometry results significantly changed. Of the cases, 88% achieved a flap with the expected width and height and complete closure of the velopharyngeal sphincter. One patient required flap revision. Four of the 8 patients achieved normal resonance, and 2 of 8 showed mild hypernasality. Using the pharyngeal flap pharyngoplasty as a primary technique to correct velopharyngeal insufficiency in patients with chromosome 22 deletion provides satisfactory outcomes and decreases the number of surgeries. Preoperative planning must be conducted carefully and needs to be individualized to be successful.

Normative nasalance scores in Chilean adults.

PURPOSE: The present study is aimed towards determining and comparing normative nasalance scores in Chilean Spanish-speaking adult men and women. METHODS: 40 women (age range 18 to 35, X = 25.79, SD = 5.83) and 36 men (age range 18 to 35, X = 26.45, SD = 4.08) were invited to participate, all of them without any previous speech therapy, neurological pathologies, intellectual deficits, hearing loss, syndromes, or other diagnosed pathologies that could impact speech production.A study of proper velopharyngeal function was performed, using a perceptual resonance evaluation. Nasalance was determined using a model 6450 Nasometer, during the reading of three standardized speech samples in Spanish: a nasal passage (NP), an oronasal passage (ONP), and an oral passage (OP). Also, the nasalance distance was calculated. Genders were compared using Wilcoxon tests for independent samples. RESULTS: The NP presented the highest percentage of nasalance, with 52.13% (± 4.73), followed by the ONP with 25.38% (± 3.7), and finally the OP, which presented the lowest value of 14.15% (± 5.03). Meanwhile, nasalance distance was 37.98% (± 5.32). Finally, no significant differences were observed when comparing the nasalance between genders (p >0.05). CONCLUSION: The nasalance values obtained were similar to those observed for other Spanish speakers. Also, male and women showed similar scores. The results of this study are a contribution to the indirect assessment of velopharyngeal function in Chilean adults.

Speech pathology telepractice intervention during the COVID-19 pandemic for Spanish-speaking children with cleft palate: A systematic review.

BACKGROUND: Due to the lockdown and quarantines caused by the COVID-19 pandemic, the need to study and use telepractice for providing speech pathology interventions for children with cleft palate has arisen. OBJECTIVE: To carry out a systematic review of the use of telepractice during the COVID-19 pandemic for providing speech pathology interventions for Spanish-speaking children with cleft palate. METHODS: In July and August 2020, the authors searched the electronic databases Medline, LILACS, SciELO, and the Cochrane Library using the following keywords in English (MeSH): Cleft palate combined with Early intervention, Speech therapy, Rehabilitation of speech and language disorders, Speech production measurement, Speech articulation tests and Telemedicine. Original articles were selected and analyzed, complemented by an analysis of flowcharts and recommendations by the GES Clinical Guide of Cleft Lip and Palate of Chile's Government and the authors' expert opinions. RESULTS: A total of 2680 articles were retrieved, of which 23 were critically analyzed and used to adapt the early stimulation, evaluation, and treatment of children with CP to speech therapy telepractice at the Gantz Foundation, a Hospital in Santiago de Chile. LIMITATIONS: Only three researchers carried out a quick review, which limited the depth of individual analysis of the studies included. Also, the suggestions and material presented should be evaluated in future investigations. CONCLUSION: This systematic review provides useful guidelines for providing speech pathology interventions through telepractice for children with cleft palate. Audiovisual materials seem to be extremely useful for families receiving the interventions. The use of interactive videos for Spanish-speaking children and educational videos for parents is manifest.

Planificación quirúrgica de colgajo faríngeo a medida para insuficiencia velofaríngea secundaria a fisura de paladar: reporte de caso y revisión de literatura / Surgical planning of a tailor-made pharyngeal flap for velopharyngeal insufficiency secondary to a cleft palate: case report and literature review

Resumen La insuficiencia velofaríngea (IVF) es una de las principales secuelas estructurales tras la palatoplastía primaria en casos de fisura de paladar. La IVF se caracteriza por la ausencia de tejido suficiente para lograr un cierre adecuado del mecanismo velofaríngeo durante el habla, lo que conlleva a una resonancia hipernasal y la emisión nasal de aire durante la producción de sonidos orales. Al respecto, el tratamiento ideal para corregir la IVF es quirúrgico, dentro de los cuales el colgajo faríngeo de pedículo superior es uno de los procedimientos más utilizados en nuestro país. Para su realización es fundamental determinar el ancho necesario, lo cual puede ser determinado mediante una videofluoroscopía multiplano (VFMP). Por esto, con el objetivo de potenciar el trabajo multidisciplinario en la corrección quirúrgica de la IVF, a continuación, se presentan los procedimientos de evaluación fonoaudiológica, videonasofaríngoscopía flexible y videofluoroscopía multiplano utilizados para la planificación quirúrgica de un colgajo faríngeo en un adolescente chileno diagnosticado con IVF secundaria a fisura palatina operada. Además, se describe el uso de la VFMP en la planificación quirúrgica del colgajo faríngeo mediante una revisión de literatura.

Abstract Velopharyngeal insufficiency (VPI) is one of the main structural sequelae after primary palatoplasty in cases of cleft palate. VPI is characterized by the absence of sufficient tissue to achieve adequate closure of the velopharyngeal mechanism (VFM) generating hyper-nasal resonance and nasal emission during the production of oral sounds. In cases of cleft palate, the ideal treatment to correct VPI is surgery. The upper pedicle pharyngeal flap is one of the most widely used procedures. To plan it, is essential to determine the appropriate width, which can be determined by means of multiplane videofluoroscopy (MPVF). For this reason, and with the aim of promoting multidisciplinary approach in the surgical correction of VPI, the following procedures such as speech and language evaluation, flexible videonasopharyngoscopy and multiplane videofluoroscopy used for the surgical planning of a pharyngeal flap, in a Chilean adolescent diagnosed with VPI secondary to operated cleft palate, will be presented. In addition, the use of MPVF in pharyngeal flap surgical planning is described through a literature review.

RESUMEN Objetivo El presente estudio tiene como objetivo determinar y comparar puntajes normativos de nasalancia en hombres y mujeres chilenos de habla hispana. Método Participaron 40 mujeres (rango de edad de 18 a 35, X = 25.79, DE = 5.83) y 36 hombres (rango de edad de 18 a 35, X = 26.45, DE = 4.08), todos sin ningún antecedente de tratamiento fonoaudiológico, patologías neurológicas, déficit intelectual, hipoacusia, síndromes u otras patologías diagnosticadas que podrían afectar la producción del habla. La adecuada función velofaríngea fue determinada en vivo a través de una evaluación perceptual de la resonancia. La nasalancia se determinó utilizando un Nasometer modelo 6450, durante la lectura de tres muestras de habla estandarizadas en español: un párrafo nasal (PN), un párrafo oronasal (PON) y un párrafo oral (PO). Además, se calculó la distancia de nasalancia. La comparación entre ambos sexos fue realizada con el test de Wilcoxon para muestras independientes. Resultados El PN presentó el mayor porcentaje de nasalancia con 52.13% (± 4.73), seguido del PON con 25.38% (± 3.7), y finalmente el PO, que presentó el valor más bajo de 14.15% (± 5.03). En tanto, la distancia de nasalancia fue del 37.98% (± 5.32). Por último, no se observaron diferencias significativas al comparar entre ambos sexos (p> 0.05). Conclusión Los valores de nasalancia obtenidos fueron similares a los observados para otros hispanohablantes. Además, hombres y mujeres mostraron puntuaciones similares. Los resultados de este estudio son una contribución a la evaluación indirecta de la función velofaríngea en adultos chilenos.

Fisiología del esfínter velofaríngeo durante la deglución. Revisión sistemática de literatura

Resumen El objetivo de este artículo es describir el funcionamiento del esfínter velofaríngeo (EVF) durante la deglución, mediante una revisión de literatura. En febrero de 2020, las bases de datos electrónicas Medline, LILACS, SciELO e IBECS, fueron consultadas retrospectivamente, usando las palabras claves en inglés: "velopharyngeal sphincter" o "pharyngeal muscles". Fueron seleccionados artículos originales que describen la fisiología del EVF en la deglución de adultos sanos. Para este estudio fue creado un protocolo que contempla lo siguiente: autor, año, país, número y características de los participantes, actividades evaluadas, metodologías e instrumentos utilizados y principales resultados. Fueron encontrados 4.124 artículos. 3.863 fueron excluidos luego de la lectura de los títulos, 239 luego de lectura de los resúmenes y 8 luego de la revisión de los textos completos. Finalmente, 14 artículos fueron analizados en esta revisión. Se discuten eventos espaciales y temporales del EVF, la actividad electromiográfica de la musculatura del EVF y la presión velofaríngea durante la deglución en adultos sanos. Se concluye que el esfínter velofaríngeo cumple un rol importante en la fase faríngea de la deglución, que debe ser profundizado en futuras investigaciones.

Abstract The aim of this article is to describe the functioning of the velopharyngeal sphincter (VPS) during swallowing, through a literature review. In February 2020, the electronic databases Medline, LILACS, SciELO and IBECS were retrospectively consulted, using the key words in English: "velopharyngeal sphincter" or "pharyngeal muscles". Original articles were selected that describe the physiology of VPS in healthy adult swallowing. For this study it was created a protocol that includes the following items: author, year, country, number and characteristics of the participants, evaluated activities, methodologies and instruments used, and main results. 4124 articles were found. 3,863 were excluded after reading the titles, 239 after reading the abstracts and 8 after reviewing the full texts. Finally, 14 articles were analyzed in this review. Spatial and temporal events of the VPS, the electromyographic activity of the VPS musculature, and velopharyngeal pressure during swallowing in healthy adults are discussed. We conclude that the velopharyngeal sphincter plays an important role in the pharyngeal phase of swallowing, which should be studied in depth in future research.
