Purpose: Secretion bubbling on the superior aspect of the velopharyngeal (VP) valve typically occurs with a small VP opening during production of oral pressure consonants. The use of high-speed nasopharyngoscopy has shown correlation between the bubbling frequency and the acoustics captured with the nasal microphone of the nasometer. The purpose of this study was to investigate if the sound generated by the bubbling process is perceived as nasal rustle (also known as nasal turbulence). Method: Speech samples were extracted from the data of patients who were diagnosed with nasal rustle (five boys and five girls, ranging in age from 5 to 10 years old). A customized filter was used to remove the sound generated by the secretion bubbling. Six experienced listeners were asked to rate the perception of nasal rustle in each speech stimuli before and after the filtering process. Results: Rating values for the perception of nasal rustle were overall reduced in all cases after the filtering process. Furthermore, the perception of nasal rustle was eliminated in 40% of the cases. Rating reliability was excellent before the filtering process and moderate to good after filtering. Conclusion: Reducing the perception of nasal rustle using spectral filtering based on the bubbling frequencies supports the hypothesis that undesired sound in the nasal cavity is generated from the interaction of the turbulent airflow with the secretion bubbling.

The purpose of this article is to (1) define the diagnostic characteristics of ankyloglossia, (2) identify potential problems associated with ankyloglossia, and (3) discuss treatment options, when treatment is appropriate. This article is based on a review of the literature, including recent systematic reviews, and the author's experience as a cleft and orofacial specialist. Ankyloglossia is a common congenital condition characterized by an anterior attachment of the lingual frenulum on the tongue. This causes difficulty elevating and/or protruding the tongue tip. As such, ankyloglossia has been thought to affect neonatal feeding, speech, and other functions. Although systematic reviews have concluded that most infants with ankyloglossia can be fed normally, a small percentage of affected infants will show improved efficiency of feeding post-frenotomy. They also concluded that frenotomy may relieve nipple pain in the breastfeeding mothers of affected infants. Regarding speech, the systematic reviews concluded that there is no evidence that ankyloglossia causes speech disorders. This may be because simple compensations will result in normal acoustics of the sounds. Therefore, frenotomy should be recommended sparingly for newborn infants, and it should rarely, if ever, be recommended for speech disorders. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this study was to obtain information regarding the education and experience of preschool and school-based speech-language pathologists (SLPs) regarding the assessment and treatment of children born with cleft lip and/or palate and to determine their continuing education needs in this area. Method: A 16-item mixed-methods survey to collect quantitative and qualitative data was distributed via postal mail to a geographically diverse random sample of 565 preschool and school SLPs. Results: The response rate was 59%. With an average of 15.93 years in practice, respondents reported that they infrequently saw children with cleft lip/palate. When treating these children, respondents wanted communication with the cleft-craniofacial team, accessible continuing education through Web sites and conferences, and clinically practical information relevant to the school setting. Conclusion: When assessing and treating a low-incidence population such as children with cleft-related communication disorders, school-based SLPs need accessible, accurate continuing education resources and collaboration with specialists in the field.

Resonance disorders can have a variety of causes but the appropriate evaluation includes a speech pathology evaluation and may require a videofluoroscopic speech study or nasopharyngoscopy assessment. Treatment may include surgery or the use of prosthetic devices, and usually speech therapy. An interdisciplinary approach is best. (Author/DB)

Objective: To establish nasalance score norms for adolescent and young adult native speakers of American English and also determine age-group and gender differences using the Simplified Nasometric Assessment Procedures (SNAP) Test-R and Nasometer II. Design: Prospective study using a randomly selected sample of participants. Setting: Greater Cincinnati area and Miami University of Ohio. Participants: Participants had a history of normal speech and language development and no history of speech therapy. Participants in the adolescent group were recruited from schools in West Clermont and Hamilton County, whereas the young adults were recruited from Miami University of Ohio. The participants of both groups were residents of Cincinnati, Ohio or Oxford, Ohio and spoke midland American English dialect. Outcome Measures: Mean nasalance scores for the SNAP Test-R. Results: Normative nasalance scores were obtained for the Syllable Repetition/Prolonged Sounds, Picture-Cued, and Paragraph subtests. Results showed statistically significant nasalance score differences between adolescents and young adults in the Syllable Repetition, Picture-Cued, and Paragraph subtests, and between males and females in the Syllable Repetition and the Sound-Prolonged subtests. A significant univariate effect was found for the syllables and sentences containing nasal consonants and high vowels compared to syllables and sentences containing oral consonants and low vowels. Across all the SNAP Test-R subtests, the females' nasalance scores were higher than the males. A significant univariate effect was also found across nasal syllables, and high vowels such that the females' nasalance scores were higher than the males. Tables of normative data are provided that may be useful for clinical purposes. Conclusion: Norms obtained demonstrated nasalance score differences according to age and gender, particularly in the Syllable Repetition/Prolonged Sound subtest. These differences were discussed in light of potential reasons for their existence and implications for understanding velopharyngeal function. In addition, nasalance scores are affected by the vowel type and place of articulation of the consonant. These facts should be considered when nasometry is used clinically and for research purposes.

Purpose: The purpose of this study was to investigate the clinical application of the Intelligibility in Context Scale (ICS) instrument in children with velopharyngeal insufficiency (VPI). This study investigated the relationship between clinical speech outcomes and parental reports of speech intelligibility across various communicative partners. Methods: The ICS was completed by the parents of 20 English-speaking children aged 4–12 years diagnosed with VPI. The parents were asked to rate their children's speech intelligibility across communication partners using a 5-point scale. Clinical metrics obtained using standard clinical transcription on the Picture-Cued SNAP-R Test were: (1) percentage of consonants correct (PCC), (2) percentage of vowels correct (PVC), and (3) percentage of phonemes correct (PPC). Nasalance from nasometer data was included as an indirect measure of nasality. Intelligibility scores obtained from naive listener's transcriptions and speech-language pathologists' (SLP) ratings were compared with the ICS results. Result: Greater PCC, PPC, PVC, and transcription-based intelligibility values were significantly associated with higher ICS values, respectively (r[20] = 0.84, 0.82, 0.51, and 0.70, respectively; p < 0.05 in all cases). There was a negative and significant correlation between ICS mean scores and SLP ratings of intelligibility (r = –0.74; p < 0.001). There was no significant correlation between ICS values and nasalance scores (r[20] = –0.28; p = 0.22). Conclusion: The high correlations obtained between the ICS with PCC and PPC measures indicate that articulation accuracy has had a great impact on parents' decision-making regarding intelligibility in this population. Significant agreement among ICS scores with naive listener transcriptions and clinical ratings supports use of the ICS in practice. [ABSTRACT FROM AUTHOR]

Objective: Palatoplasty outcome measurements vary widely among institutions. A standardized outcome metric would help provide quality benchmarks. Design: Retrospective review of primary palatoplasty patients from 2007 to 2013. Setting: Tertiary care children's hospital. Main Outcome Measures: We created a novel conceptual quality metric called "OOR" (Optimal Outcome Reporting). Optimal Outcome Reporting is designed to reflect the percentage of patients with cleft palate who experience the best outcomes: one operation, velar competence by age 5 years, and no unintended palatal fistula. Results: Optimal Outcome Reporting was 72.3% (68/94). Eight patients had "suboptimal" outcomes for having undergone more than one operation. Eighteen patients failed for velar incompetence. No additional patients fell out of the algorithm for fistula. A significantly higher proportion of nonsyndromic patients demonstrated an "optimal" result compared to syndromic patients (61/80, 76.3% vs 7/14, 50.0%; P =.04). Patients who required more than one procedure had significantly more clinic visits (32.6 vs 14.9; P <.01) and accrued higher costs compared to "optimal" patients (US$34 019.88 vs US$15 357.25; P <.01). Conclusions: Optimal Outcome Reporting represents a novel quality metric that can provide meaningful information for patients with cleft palate. Optimal Outcome Reporting utilization can help cleft centers adopt changes that matter to patients and their families. By allowing for cross-institutional comparisons in a clear and objective manner, OOR can promote competition, innovation, and value in cleft palate care. [ABSTRACT FROM AUTHOR]

Objective: The loud and severely distorting form of audible nasal emission (commonly known as nasal turbulence or nasal rustle) typically occurs with a small velopharyngeal opening during production of pressure-sensitive consonants. The purpose of this study was to determine whether bubbling of the secretions, which commonly occurs on the superior aspect of the velopharyngeal port when there is a small opening, is a periodic process that can generate sound in the nasal cavity. Participants: Ten pediatric patients were included in the study. All participants had normal articulation and resonance but exhibited audible nasal emission characterized as nasal rustle. Measures: For each participant, high-speed video (HSV) nasopharyngoscopy and acoustic signals were recorded simultaneously. The acoustic recordings were captured in a manner similar to nasometry using nasal and oral microphones connected to a separation plate. Spectral analysis of the audio recordings and the HSV images was used to determine correlation between the acoustic and visual measurements. Results: This study showed that secretion bubbling is a periodic process and its frequency, measured from the HSV data, was also captured by the acoustic measurements. The nasal acoustic signal correlated more strongly with the video of bubbling than the oral acoustic signal in the majority of the cases where bubbling occurred. Conclusion: These findings are strong evidence that secretion bubbling plays a significant role in the mechanism that generates undesired sound in the nasal cavity. Further work is needed to determine whether this sound is perceived as nasal rustle. [ABSTRACT FROM AUTHOR]

There are several different types of nasal emission that can occur during speech due to either velopharyngeal dysfunction or abnormal articulation in the pharynx. Nasal emission can be inaudible or very loud and distracting, depending on the size of the velopharyngeal opening and the physics of the flow. Nasal emission can be obligatory and/or compensatory (due to abnormal structure) or it can be caused by a misarticulation that results in a substitution of a pharyngeal sound for an oral sound, despite normal velopharyngeal structure. Nasal emission can occur on all pressure-sensitive phonemes or it can be phoneme-specific. Although it is generally recognized that the loud and distracting form of nasal emission (called nasal turbulence or nasal rustle) is due to a small velopharyngeal opening, the causality of the distracted sound is debated. This article provides a brief review of the types of nasal emission, the terms used to describe it, and the potential causes. This article also stresses the need for further research to clarify the causality of the sound generated by a small velopharyngeal opening. [ABSTRACT FROM AUTHOR]
