- Abstract
Nasometry is a non-invasive, easy-to-use technique that provides objective data regarding the amount of acoustic energy in the oral and nasal cavities during speech. The goal of this study is to create a Spanish passage and determine normative nasalance values for typical Spanish-speaking children, 3 to 5 years of age, that allows us to compare the values in children of the same age who present hypernasality and velopharyngeal dysfunction. Second, to determine if there are significant differences in nasalance scores based on age or gender. Third, to test the impact of vowel load on nasalance scores. Data were collected from 130 children with no known speech, language, or hearing disorder. Participants were organized into three groups according to age. A nasometric assessment protocol for Spanish was developed based on an adaptation of the MacKay-Kummer Simplified Nasometric Assessment Procedures-Revised (SNAP-R; 2005). All participants were required to repeat the speech stimuli. Data were collected using the icSpeech nasometer and were recorded on EXCEL 365 sheets for further analysis. Normative data is now available for a Spanish version of the SNAP-R Test. No significant differences were found between the genders, but significant differences were found based on age. It was also found that a load of high and anterior vowels, especially the phoneme /i/, increased nasalance scores. This protocol created passages in Spanish that mimic the passages of the SNAP-R Test in English. These Spanish passages were normed for Spanish-speaking children. This study confirms that high vowels result in higher nasalance values and therefore, the vowel composition of a specific passage determines the nasalance score, not the language of the passage., La nasometría es una técnica no invasiva y fácil de usar que proporciona datos objetivos sobre la cantidad de energía acústica en las cavidades oral y nasal durante el habla. El objetivo de este estudio fue crear un pasaje en español y determinar valores normativos de nasalance para niños nomotípicos hablantes de español, de 3 a 5 años, que permita comparar los valores en niños de la misma edad que presentan hipernasalidad y disfunción velofaríngea. En segundo lugar, determinar si existen diferencias significativas en las puntuaciones de nasalance en función de la edad o el sexo. Tercero, comprobar el impacto de la carga vocálica en las puntuaciones de nasalance. Se recogieron datos de 130 niños sin trastornos del habla, lenguaje o audición. Los participantes se organizaron en tres grupos según la edad. Se desarrolló un protocolo de evaluación nasométrica en español basado en una adaptación de los Procedimientos Simplificados de Evaluación Nasométrica Revisados de MacKay-Kummer (SNAP-R; 2005). Se pidió a todos los participantes que repitieran los estímulos del habla. Los datos de cada participante se recogieron utilizando el software del nasómetro icSpeech y se registraron en hojas EXCEL 365 para su posterior análisis. En este trabajo se presentan datos normativos para una versión española del Test SNAP-R. No se encontraron diferencias significativas entre los géneros, pero sí en función de la edad. También se encontró que una carga de vocales altas y anteriores, especialmente el fonema /i/, aumentaba las puntuaciones de nasalance. Este protocolo creó pasajes en español adaptados a los pasajes del Test SNAP-R en inglés. Estos pasajes fueron normalizados para niños hispanohablantes. Este estudio confirma que las vocales altas dan lugar a valores de nasalance más altos y, por tanto, la composición vocálica de un pasaje específico determina la puntuación de nasalance, no el idioma del pasaje.

3. The Source of Nasal Rustle (Nasal Turbulence): An Overview of Current Evidence

Rollins, Michael and Kummer, Ann
- Abstract
Objective Nasal rustle(also called nasal turbulence) refers to a loud distracting sound that sometimes occurs with audible nasal emission (ANE) during the production of pressure-sensitive consonants in patients with velopharyngeal insufficiency (VPI). This article examines evidence for two hypotheses of causality: vibration of the soft palate (velar flutter) and periodic motion of mucus above the velopharyngeal port (turbulent mucus).Conclusion A review of the relevant literature shows inconclusive evidence to support velar flutter as a cause of nasal rustle. In contrast, clinical observations and research involving high-speed nasopharyngoscopy suggest that nasal rustle is the result of turbulent mucus above a small velopharyngeal opening. Therefore, it is our contention that a plausible explanation for nasal rustle is one of turbulent mucus and not velar flutter.

- Abstract
Objective The inaugural Cleft Summit aimed to unite experts and foster interdisciplinary collaboration, seeking a collective understanding of velopharyngeal insufficiency (VPI) management.Design An interactive debate and conversation between a multidisciplinary cleft care team on VPI managementSetting A two-hour discussion within a four-day comprehensive cleft care workshop (CCCW).Participants Thirty-two global leaders from various cleft disciplinesInterventions Cleft Summit that allows for meaningful interdisciplinary collaboration and knowledge exchange.Main Outcome Measures Ability to reach consensus on a unified statement for VPI management.Results Participants agreed that a patient with significant VPI and a dynamic velum should first receive a surgery that lengthens the velum to optimize patient outcome. A global, multicenter prospective study should be done to test this hypothesis.Conclusion The 1st Cleft Summit successfully distilled global expertise into actionable best-practice guidelines through iterative discussions, fostering interdisciplinary collaboration and paving the way for a transformative multi-center prospective study on VPI care.
