Speech Outcomes Audit for Unilateral Cleft lip and Palate After 2-Stage Palate Repair: Preliminary Results.

Primary cleft lip and palate surgeries can interfere with speech status, facial appearance, maxillary growth, and psychosocial and academic development. Therefore, different surgical protocols and techniques have been proposed, and adequate velopharyngeal function and speech is the main goal for the treatment success. The present study aimed to report preliminary speech results of the 2-stage palate repair of children with unilateral cleft lip and palate. One hundred seventy nonsyndromic patients with unilateral cleft lip and palate were included in this report, 35% males and 65% females, submitted to the 2-stage palatoplasty protocol, composed by lip, nasal ala, and hard palate repair at 3 to 6 m (stage 1) and soft palate repair at 12 to 18 m (stage 2). The target age range for speech recording was 5 to 10 years, and the speech material included repetition of Brazilian Portuguese sentences. These samples were obtained over 5 years and assessed by 3 of 14 experienced speech pathologists. When discordant, the majority rate was adopted. Average velopharyngeal dysfunction (VPD) rates were 19,5%, varying according to the soft palate technique, with better results when the Sommerlad technique was performed (VPD=11%), followed by Braithwaite (VPD=15%) and then Von Langenbeck (VPD=25%). Passive errors were observed in 32% and active errors in 25%. Speech results reflect the outcomes of an interdisciplinary team's work, where facial growth and nasolabial appearance must also be considered. Further analysis and a wider casuistic are recommended. Hence outcomes audit needs to be a permanent process, providing solid and updated evidence for optimal cleft care.

Models for Predicting Velopharyngeal Competence Based on Speech and Resonance Errors and Velopharyngeal Area Estimation.

OBJECTIVE: To develop tools for predicting velopharyngeal competence (VPC) based on auditory-perceptual assessment and its correlation with objective measures of velopharyngeal orifice area. DESIGN: Methodological study. PARTICIPANTS AND METHODS: Sixty-two patients with repaired cleft palate, aged 6 to 45 years, underwent aerodynamic evaluation by means of the pressure-flow technique and audiovisual recording of speech samples. Three experienced speech-language pathologists analysed the speech samples by rating the following resonance, visual, and speech variables: hypernasality, audible nasal air emission, nasal turbulence, weak pressure consonants, facial grimacing, active nonoral errors, and overall velopharyngeal competence. The correlation between the perceptual speech variables and velopharyngeal orifice area estimates was analysed with Spearman's correlation coefficient. Two statistical models (discriminant and exploratory) were used to predict VPC based on the orifice area estimates. Sensitivity and specificity analyses were performed to verify the clinical applicability of the models. RESULTS: There was a strong correlation between VPC (based on the orifice area estimates) and each speech variable. Both models showed 88.7% accuracy in predicting VPC. The sensitivity and specificity for the discriminant model were 92.3% and 97.2%, respectively, and 96.2% and 94.4% for the exploratory model. CONCLUSION: Two predictor models based on ratings of resonance, visual, and speech variables and a simple calculation of a composite variable, SOMA (Eng. "sum"), were developed and found to be efficient in predicting VPC defined by orifice estimates categories based on aerodynamic measurements. Both tools may contribute to the diagnosis of velopharyngeal dysfunction in clinical practice.

Effect of Orthognathic Surgery on Breathing in Patients with Cleft lip and Palate: 20-Year Experience at a Tertiary Hospital in Brazil.

OBJECTIVE: To verify the effect of orthognathic surgery (OS) on nasal dimensions and its correlation with respiratory symptoms in patients operated on over the past 20 years. DESIGN: Retrospective study. SETTING: Tertiary level craniofacial hospital. PARTICIPANTS: 535 patients with CLP previously repaired, without syndromes, age over 18, who performed OS between 2000 and 2019 and rhinomanometric evaluation pre and post OS. INTERVENTIONS: Maxillary advancement isolated and combined with turbinectomy and/or mandibular osteotomy. MAIN OUTCOME MEASURES: Minimum nasal cross-sectional area (CSA) assessed by posterior (PR) and anterior rhinomanometry (AR), nasopharyngeal cross-sectional area (NCSA) verified by modified AR, and self-perceived respiratory symptoms through a questionnaire. RESULTS: After OS, there was a significant increase in CSA assessed by PR (p < .001) and AR (p < .001), while there was no significant difference in NCSA (p = 0.319). Regarding respiratory symptoms after OS, 26.3% showed improvement in nasal obstruction, 28.5% in oronasal breathing, 18.5% in snoring, and 5.2% in respiratory obstruction during sleep. However, a weak correlation between increased CSA and improvement of symptoms was observed. In the first decade, lower values of CSA (p < .001) and NCSA (p < .001) were observed compared to the second decade. Both periods showed a significant increase in CSA (p < .001). CONCLUSIONS: Nasal dimensions and breathing symptoms were improved by OS when combined with turbinectomy. Comparing the results of patients operated on between two different decades, patients had more favorable conditions for breathing in the most recent decade of care. However, this was not statistically correlated with the improvement in patient symptoms in this study.

Evaluation of the Nasopharyngeal Cannula Use After Orthognathic Surgery: Permeability of the Nasal Airways and Discomfort of the Patient With Cleft Lip and Palate.

It is believed that the use of the nasopharyngeal cannula can maintain the patent upper airway in the immediate post-operative period of orthognathic surgery. The present study is a randomized clinical trial with the objective of evaluating the difference in the use of the nasopharyngeal cannula in the post-operative period of orthognathic surgery with respect to permeability and discomfort. The sample was composed of 26 individuals with repaired cleft lip and palate randomly distributed in 2 groups with and without nasopharyngeal cannula. The evaluation was composed by Visual Analogue Scale (VAS), test with Altman mirror in 4 pre-operative periods, 6, 24, 30 hours after the operation. Rhinomanometry was also performed, a flow- pressure technique in 2 distinct moments, 6 and 24 hours after surgery. As a result, greater discomfort, greater obstruction as well as a reduction in the area of bilateral minimum nasal cross-section (ASTM) and increased resistance in the group with nasopharyngeal cannula are observed. In the intra-group comparison with the lowest ASTM values, the test group showed a significant difference between the first and the second moments (P = 0.001). It can be concluded that the nasopharyngeal cannula contributes to increase discomfort, worsens airway permeability by decreasing ASTM and increasing nasal resistance. Regarding the length of stay of the nasopharyngeal cannula, it can be said that from 6 hours onwards it does not contribute to the reduction of discomfort, airway permeability and assist in hemostasis.

Predictors of Velopharyngeal Dysfunction in Individuals With Cleft Palate Following Surgical Maxillary Advancement: Clinical and Tomographic Assessments.

OBJECTIVE: To investigate whether morphofunctional velopharyngeal aspects may be considered predictors of appearance or worsening of hypernasality in patients with cleft palate after surgical maxillary advancement (MA). DESIGN: Prospective. SETTING: National referral center for cleft lip and palate rehabilitation. PARTICIPANTS: Fifty-two patients with repaired cleft palate, skeletal class III malocclusion, and normal speech resonance completed speech audio recordings and cone-beam computed tomography examination before (T1) and, on average, 14 months after (T2) MA. INTERVENTIONS: Hypernasality was rated by 3 experienced speech-language pathologists using a 4-point scale and morphofunctional aspects on a 3-point scale. Cone-beam computed tomography image measurements were performed using Amira and Dolphin 3D software. For each velopharyngeal morphofunctional aspect analyzed, patients were compared according to the absence (G1) and presence (G2) of postoperative hypernasality. MAIN OUTCOME MEASURES: Comparison of hypernasality scores between T1 and T2 and association between hypernasality and each velopharyngeal morphofunctional aspect. RESULTS: Significant difference was observed between T1 and T2 for hypernasality ( P = .031) and between G1 and G2 ( P = .015) for velar mobility, with significant association between this variable and hypernasality on T2 (P = .041). CONCLUSIONS: Levator veli palatini mobility influenced the appearance of hypernasality after MA.

Normative nasalance scores in the production of words and syllables for Brazilian Portuguese speakers.

The objective of this study was to determine normative nasalance scores for non-cleft children, adolescents and adults, native speakers of Brazilian Portuguese, during the production of words and syllables, for cross-linguistic comparisons in populations with and without cleft palate. Nasalance was assessed in 62 individuals, aged 6-10 years (n = 20), 11-17 years (n = 20) and 18-35 years (n = 22), using a nasometer II model 6450 (KayPENTAX), during production of one sequence of nine oral words (pipa, bis, burro, tatu, pilha, cuca, gui, fila, luz) and of sequences of isolated syllables (e.g. pa, pa, pa, pa, pa, pa) composed of plosive, fricative, liquid and nasal consonants with high and low vowels. In order to validate the new nasalance stimuli, nasalance scores for traditional oral and nasal stimuli were also obtained. Differences were analyzed at a significance level of 0.01. Mean nasalance scores (±SD) during the production of the sequence of words were 18 ± 5% (children), 18 ± 7% (adolescents) and 21 ± 5% (adults). Differences between age groups were not significant. During the production of syllables, adults had the highest mean nasalance scores (except for syllable /mi/); significant differences between age groups were observed only for /pa/ ,/sa/ and /la/. Nasalance scores were significantly higher in oral and nasal syllables with high vowels than with low vowels, and in nasal syllables than in oral syllables with high and low vowels. The nasalance scores obtained for the sentences were comparable to previously established norms. In conclusion, the nasalance scores defined for Brazilian Portuguese speakers, in different stimuli, may be adopted as normative values for local and cross-language comparisons in the identification of hypernasality related to conditions such as cleft palate, neurogenic disorders and syndromes.

Reliability of Hypernasality Rating: Comparison of 3 Different Methods for Perceptual Assessment.

OBJECTIVE: To compare reliability in auditory-perceptual assessment of hypernasality for 3 different methods and to explore the influence of language background. DESIGN: Comparative methodological study. PARTICIPANTS AND MATERIALS: Audio recordings of 5-year-old Swedish-speaking children with repaired cleft lip and palate consisting of 73 stimuli of 9 nonnasal single-word strings in 3 different randomized orders. Four experienced speech-language pathologists (2 native speakers of Brazilian-Portuguese and 2 native speakers of Swedish) participated as listeners. After individual training, each listener performed the hypernasality rating task. Each order of stimuli was analyzed individually using the 2-step, VISOR and Borg centiMax scale methods. MAIN OUTCOME MEASURES: Comparison of intra- and inter-rater reliability, and consistency  for each method within language of the listener and between listener languages (Swedish and Brazilian-Portuguese). RESULTS: Good to excellent intra-rater reliability was found within each listener for all methods, 2-step: κ = 0.59-0.93; VISOR: intraclass correlation coefficient (ICC) = 0.80-0.99; Borg centiMax (cM) scale: ICC = 0.80-1.00. The highest inter-rater reliability was demonstrated for VISOR (ICC = 0.60-0.90) and Borg cM-scale (ICC = 0.40-0.80). High consistency within each method was found with the highest for the Borg cM scale (ICC = 0.89-0.91). There was a significant difference in the ratings between the Swedish and the Brazilian listeners for all methods. CONCLUSIONS: The category-ratio scale Borg cM was considered most reliable in the assessment of hypernasality. Language background of Brazilian-Portuguese listeners influenced the perceptual ratings of hypernasality in Swedish speech samples, despite their experience in perceptual assessment of cleft palate speech disorders.

Obstructive Sleep Apnea Following Pharyngeal Flap Surgery for Velopharyngeal Insufficiency: A Prospective Polysomnographic and Aerodynamic Study in Middle-Aged Adults.

OBJECTIVE: To compare the frequency and severity of obstructive sleep apnea (OSA) in middle-aged adults who underwent pharyngeal flap surgery for velopharyngeal insufficiency (VPI) with matched subjects who did not undergo pharyngeal flap surgery and to verify the relationship between OSA severity and internal pharyngeal dimensions. SETTING: National referral care center for cleft lip and palate. METHOD: Prospective study on 42 nonsyndromic subjects with repaired cleft palate with flap (F group, n = 22) and without flap (NF group, n = 20), aged 40 to 58 years. The main outcome measure was the apnea-hypopnea index (AHI), measured by in-lab nocturnal polysomnography (PSG). The OSA-related symptoms were investigated by Pittsburgh, Epworth, and Berlin questionnaires. The nasopharyngeal or velopharyngeal (NP/VP) cross-sectional area was measured by modified anterior rhinomanometry in subgroups of the F (n = 14) and NF (n = 10) groups at rest and during speech. Differences were considered significant at P < .05. RESULTS: Questionnaire scores and frequency of self-reported symptoms of snoring, nasal obstruction, and breathing interruptions during sleep did not differ between groups. OSA was diagnosed by PSG in 60% and 77% of the NF and F subjects, respectively. The difference was not significant. No cases of severe OSA were observed. There was no correlation between AHI and NP/VP area. CONCLUSION: A significant number of middle-aged adults with repaired cleft palate had OSA and related symptoms, regardless of the presence of a pharyngeal flap. Results suggest that VPI treatment with a flap may not cause sleep-disordered breathing in the cleft population. Besides advancing age, congenital upper airway abnormalities may be involved.

Facial grimace during speech in cleft lip and palate: a proposal for classification. / Mímica facial durante a fala em fissura labiopalatina: uma proposta de classificação.

PURPOSE: To investigate the effectiveness of a proposal for classification of facial grimace (FG) and its correlation with objective evaluation of velopharyngeal closure (VPC). METHODS: Twenty individuals with repaired cleft lip and palate underwent velopharyngeal area measurement by means of rhinomanometry and speech sample recording. The FG was rated in two steps, by three speech-language pathologists. First the evaluators rated the FG using their own criteria as: 1= absent FG; 2=mild; 3=moderate; 4=severe. Subsequently, they were submitted to a training session that established the following FG rating criteria: 1=absent FG; 2=movement only of the nose or upper third of the face; 3=strong movement of the nose or upper third of the face; 4=movement of the nose and upper third of the face. The evaluators rated the FG using the established criteria. Intra- and inter-rater agreement were calculated using weighted Kappa coefficient. Correlation between the two stage ratings with the VPC was calculated by Spearman's correlation coefficient. RESULTS: In the first stage inter-rater agreement ranged from fair to substantial; in the second stage, from substantial to almost perfect. Intra-rater agreement ranged from moderate to almost perfect in the first stage, and from moderate to substantial in the second stage. The correlation between FG and velopharyngeal area was positive and significant in both stages. CONCLUSION: The proposed FG judgement proved to be effective in determining the symptom and reliable in diagnosing the severity of velopharyngeal dysfunction. The significant correlation between perceptual and instrumental methods suggests that FG can be used in predicting VPC.

MÉTODO: Vinte indivíduos com fissura labiopalatina reparada foram submetidos à medida da área velofaríngea por meio da rinomanometria e à gravação de amostra de fala. A MF foi classificada em dois momentos, por três fonoaudiólogas. Inicialmente as avaliadoras classificaram a MF, utilizando critérios próprios, em: 1=MF ausente; 2=leve; 3=moderada; 4=grave. Posteriormente, foram submetidas a um treinamento com o estabelecimento dos seguintes critérios de classificação: 1=MF normal; 2=movimento somente de nariz ou terço superior da face; 3=movimento acentuado de nariz ou terço superior da face; 4=movimento de nariz e terço superior da face e, classificaram a MF utilizando os critérios estabelecidos. Concordância intra e interavaliadores foram calculadas pelo coeficiente Kappa ponderado. A correlação entre os resultados das etapas com o FVF foi feita pelo coeficiente de correlação de Spearman. RESULTADOS: Na primeira etapa, a concordância interavaliadores variou de regular a substancial e na segunda, de substancial a quase perfeita. A concordância intra-avaliadores variou de moderada a quase perfeita na primeira etapa, e de moderada a substancial, na segunda etapa. A correlação entre a MF e área velofaríngea na primeira e na segunda etapa foi positiva e significativa. CONCLUSÃO: A proposta de julgamento da MF mostrou-se efetiva na determinação do sintoma e confiável no diagnóstico da gravidade da disfunção velofaríngea. A correlação significativa entre os métodos perceptivo e instrumental sugere que a MF pode ser utilizada na previsão do FVF.

Speech outcomes and velopharyngeal function after surgical treatment of velopharyngeal insufficiency in individuals with signs of velocardiofacial syndrome.

OBJECTIVE: The objective of the study was to analyze if individuals with velocardiofacial syndrome (VCFS) present the same characteristics of speech and velopharyngeal function (VPF) compared with patients with nonsyndromic submucous cleft palate, as well as to compare the effectiveness of palate surgery on the speech function and VPF between groups. METHODS: This was a prospective study performed at the Speech Therapy Sector and Physiology Laboratory, Hospital for Rehabilitation of Craniofacial Anomalies/University of São Paulo.The procedure performed was primary palatoplasty associated or not to superiorly based pharyngeal flap surgery.There were 50 patients with velopharyngeal insufficiency: 25 with signals of VCFS (VCFS group) and 25 without syndrome with submucous cleft palate (SMCP group).The hypernasality was scored by 3 examiners; nasalance was evaluated by nasometry, and VPF was assessed by the size of the velopharyngeal gap on the nasoendoscopy. The evaluations were conducted before and, in average, 18 months after surgery. RESULTS: Before surgery, the VCFS and SMCP groups presented similar speech function and VPF characteristics in all parameters, with no statistically significant differences. After surgery, there was reduction in the hypernasality, nasalance, and VPF in, respectively, 20%, 31%, and 36% of patients in the VCFS group and in 24%, 30%, and 30% in the SMCP group. Elimination/normalization of variables was obtained in 28%, 19%, and 8% of patients in the VCFS group and 20%, 40%, and 25% in the SMCP group, respectively, for hypernasality, nasalance, and VPF. There was no statistically significant difference between groups. CONCLUSIONS: Patients with VCFS presented similar speech function and VPF characteristics as patients with nonsyndromic SMCP. The surgery for velopharyngeal insufficiency correction was equally effective for the improvement and resolution of speech symptoms and VPF in patients with VCFS compared with the SMCP group.

Surgical maxillary advancement and speech resonance: comparison among cleft types. / Avanço cirúrgico de maxila e ressonância de fala: comparação entre os tipos de fissura.

Purpose This study investigated the influence of the cleft type on the appearance of hypernasality after surgical maxillary advancement (MA). Methods Nasality was determined by measurement of nasalance (acoustic correlate of nasality) by nasometry. The study involved analysis of the nasalance scores of 17 individuals with isolated cleft palate (CP), 118 with unilateral cleft lip and palate (UCLP) and 69 with bilateral cleft lip and palate (BCLP), of both sexes, aged 18 to 28 years, after MA. Only individuals with normal nasalance scores indicating balanced resonance before MA were included in this study. Nasometry was performed 3 days before and 15 months after MA, on average. The proportion of patients who presented nasalance scores indicating hypernasality after surgery was calculated by the ANOVA test, and comparison among the different cleft types was evaluated by the chi-square test (p < 0.05). Results No significant difference was found in the proportions of individuals with hypernasality among the cleft types. Conclusion Nasometry showed that the appearance of hypernasality after MA in individuals with cleft palate with or without cleft lip occurred in similar proportions, regardless of the cleft type.

Borg scale: a new method for hypernasality rating. / Escala de Borg: um novo método para avaliação da hipernasalidade de fala.

PURPOSE: To investigate the reliability in auditory-perceptual assessment of hypernasality of the Borg centiMax scale and the influence of the speech material on the reliability of two scales. METHODS: Four experienced speech-language pathologists rated hypernasality of 80 audio recordings of patients with repaired cleft palate (40 single-word string and 40 sentences) using the 5-point ordinal scale and the Borg centiMax scale. Intra and inter-rater reliability were calculated for both scales and for both types of speech samples. The comparison between the agreement coefficients of the two speech samples was calculated using the Z test and between the scales was calculated by Spearman correlation coefficient, considering as significant p<0.05. RESULTS: A very high and statistically significant correlation was found between the Borg centiMax scale and the ordinal scale for both speech samples. Intra- and inter-rater reliability was higher for Borg scale as compared to ordinal scale. Good to excellent intra-rater reliability was found for Borg scale for both speech samples. Poor to excellent intra-rater reliability was found for ordinal scale for both stimuli. Higher inter-rater reliability was demonstrated for Borg scale than ordinal scale for both speech samples. There was a significant difference between the single words string and sentences for intra- and inter-rater reliability using Borg scale, and for inter-rater reliability using ordinal scale. CONCLUSION: The Borg centiMax scale showed better intra and inter-rater reliability. Additionally, the speech material comprising of single words string showed better reliability in most of the comparisons for both scales.

OBJETIVO: Investigar a confiabilidade da escala Borg centiMax como método de avaliação perceptivo-auditiva da hipernasalidade e a influência do tipo de amostra de fala sobre a confiabilidade das avaliações. MÉTODO: Quatro fonoaudiólogas experientes classificaram a hipernasalidade de 80 amostras de fala de pacientes com fissura de palato reparada (40 vocábulos e 40 sentenças) utilizando a escala ordinal de 5 pontos e a escala Borg centiMax. Os índices de concordância intra e interavaliadores foram estabelecidos para ambas as escalas e amostras. A comparação desses índices foi feita pelo teste Z e a comparação entre as escalas foi feita pelo coeficiente de correlação de Spearman (p<0,05). RESULTADOS: Verificou-se correlação muito alta e significante entre a Escala Borg centiMax e a escala ordinal, para ambas as amostras. Os índices de concordância intra-avaliadores (CCI) para a escala Borg centiMax variaram de excelente a bom e, para a escala ordinal (Kappa), de excelente a pobre, em ambas as amostras. A concordância interavaliadores (CCI) para a escala Borg centiMax variou de excelente a moderada e, para a escala ordinal (Kappa), variou de moderada a pobre, para vocábulos e sentenças. Diferença estatisticamente significante, com melhores índices de concordância intra e interavaliadores para vocábulos, foi obtida com a escala Borg centiMax. Para a escala ordinal, diferença significante entre vocábulos e sentenças foi observada apenas para a comparação interavaliador. CONCLUSÃO: A escala Borg centiMax apresentou melhores índices de concordância intra e interavaliadores. A amostra contendo vocábulos mostrou melhores índices de concordância na maioria das comparações, para ambas as escalas.

Nasalance scores of Brazilian Portuguese speakers at 5 years of age. / Escores de nasalância de falantes do Português Brasileiro aos cinco anos de idade.

PURPOSE: To determine nasalance scores of Brazilian Portuguese speaking children without evident speech disorders, language delay and orofacial deformities, at age 5 years, and analyze differences between types of speech samples and genders. METHODS: Twenty children were analyzed, 11 males, age ranging from 4 years and 10 months to 5 years and 11 months. The Nasometer II 6450 (KayPENTAX) was used for nasalance assessment. Speech samples were eight consonant-vowel syllables and one sequence of nine words. The significance of differences between speech samples and genders were assessed by the Tukey test and Mann-Whitney test, respectively, at a significance level of 5%. RESULTS: Mean nasalance scores were: /pa/= 10±4%, /pi/= 22±7%, /sa/= 11±5%, /si/= 24±11%, /ma/= 57±11%, /mi/= 73±13%, /la/= 14±9%, /li/= 25±11%, words (pipa, bis, burro, tatu, pilha, cuca, gui, fila, luz)= 20±6%. Nasalance scores of nasal syllables were significantly higher than those of oral syllables (with high or neutral vowels) and nasalance scores of oral syllables with high vowels were significantly higher than those of oral syllables with neutral vowels, for the majority of comparisons. There was no difference between genders. CONCLUSION: Normative nasalance scores for 5-year-old Brazilian children were determined. The methodology can serve as a standard for the early diagnosis of nasality deviations, such as hypernasality observed in cleft palate speech.

Influence of speech sample on perceptual rating of hypernasality. / Influência da amostra de fala na classificação perceptiva da hipernasalidade.

PURPOSE: To investigate the influence of speech sample of spontaneous conversation or sentences repetition on intra and inter-rater hypernasality reliability. METHODS: One hundred and twenty audio recorded speech samples (60 containing spontaneous conversation and 60 containing repeated sentences) of individuals with repaired cleft palate±lip, both genders, aged between 6 and 52 years old (mean=21±10) were selected and edited. Three experienced speech and language pathologists rated hypernasality according to their own criteria using 4-point scale: 1=absence of hypernasality, 2=mild hypernasality, 3=moderate hypernasality and 4=severe hypernasality, first in spontaneous speech samples and 30 days after, in sentences repetition samples. Intra- and inter-rater agreements were calculated for both speech samples and were statistically compared by the Z test at a significance level of 5%. RESULTS: Comparison of intra-rater agreements between both speech samples showed an increase of the coefficients obtained in the analysis of sentences repetition compared to those obtained in spontaneous conversation. Comparison between inter-rater agreement showed no significant difference among the three raters for the two speech samples. CONCLUSION: Sentences repetition improved intra-raters reliability of perceptual judgment of hypernasality. However, the speech sample had no influence on reliability among different raters.

The influence of listener training on the perceptual assessment of hypernasality. / Influência do treinamento dos avaliadores no julgamento perceptivo da hipernasalidade.

Introduction A high agreement in the perceptual assessment of hypernasality among different listeners is difficult to achieve. Prior listener training and the standardization of analysis criteria may be effective strategies to decrease the effect of perceptual assessment subjectivity and increase the agreement among listeners. Objective To investigate the influence of prior training on agreement among different listeners in the perceptual assessment of hypernasality. Methods Three experienced speech-language pathologists analyzed 77 audio-recorded speech samples of individuals with repaired cleft palate. During the first phase, the listeners classified hypernasality according to their own criteria, using a 4-point scale. Seventy days later, they were required to complete the training to define the stimuli to be used as anchors for the assessment in the following phase. During the second phase, the listeners analyzed the same samples and rated hypernasality in a 4-point scale, using the anchors defined during training as the criteria. Intra- and interrater agreement in both the phases were calculated by the kappa coefficient. These values were statistically compared using the Z-test. Results The intrarater agreement obtained between the two phases of the study ranged from 0.38 to 0.92, with a statistically significant difference for one of the listeners (p=0.004). The agreement for the hypernasality degree obtained among the three listeners after training (0.54) was significantly higher than that obtained before training (0.37; p=0.044). Conclusion Listener training and the definition of criteria to rate hypernasality lead to the increase of intra- and interrater agreement.

Nasopharyngeal dimensions in normal individuals: normative data. / Dimensões nasofaríngeas em indivíduos sem anomalias craniofaciais: dados normativos.

OBJECTIVE: To establish normative values of minimum cross-sectional nasopharyngeal area in individuals without craniofacial anomalies at different age ranges. MATERIAL AND METHOD: Ninety-six individuals of both genders, without craniofacial anomalies, and with normal body mass index and neck circumference were evaluated. Participants were divided into 4 age groups: children, aged 6 to 10 years (G1); adolescents, aged 11 to 17 years (G2); young adults, 18 to 39 years (G3), and middle-aged adults, 40 to 59 years (G4). Minimum cross-sectional nasopharyngeal area (nasopharyngeal area - NPA) was assessed by means of modified anterior rhinomanometry (pressure-flow technique) using a PERCI-SARS system (version 3.50 - Microtronics Corp.). RESULTS: Mean±SD values of NPA were 1.025±0.054cm2, 1.055±0.081cm2, 1.050±0.083cm2, and 1.054±0.081cm2, respectively for groups G1, G2, G3, and G4, showing that there were no differences between the four age groups. CONCLUSION: Normative data of NPA were established for individuals without craniofacial anomalies from different age ranges, and they may be used as reference values in the clinical routine and for future studies regarding nasopharyngeal obstruction diagnosis, particularly in cases of craniofacial anomalies.

AIM: To propose a method for velopharyngeal function rating based on hypernasality, nasal air emission and compensatory articulation deficits scores. CONCLUSION: The proposed method shows several advantages in terms of clinical and research documentation and for an adequate follow-up of therapeutic and surgical outcomes.

Influence of pharyngeal flap surgery on nasality and nasalance scores of nasal sounds production in individuals with cleft lip and palate.

OBJECTIVE: To verify the influence of pharyngeal flap surgery on the management of velopharyngeal insufficiency on nasality and speech nasalance on nasal sound production in individuals with cleft lip and palate. METHODS: Prospective study in 159 individuals with repaired cleft palate ± lip, of both genders, aged 6 to 57 years old. All the participants presented residual velopharyngeal insufficiency and were submitted to pharyngeal flap surgery. Perceptual speech evaluation and nasometric assessment were performed before and after (14 months on average) the pharyngeal flap surgery. Hyponasality was rated as absent or present, and nasalance scores were determined by means of nasometer using nasal stimuli, with a cutoff score of 43% used as the lowest limit of normality. Nasality and nasalance were compared before and after surgery (p < 0.05). RESULTS: On the basis of correlation between both the methods used, perceptual hyponasality was observed in 14% of the individuals, whereas nasalance scores indicating hyponasality (< 43%) were obtained in 25% of the patients after surgery. CONCLUSION: Pharyngeal flap surgery influenced the production of nasal sounds, causing hyponasality in a significant proportion of individuals. The presence of this speech symptom can also be an indicator of upper airway obstruction caused by pharyngeal flap, which should be investigated objectively and prudently postoperatively.

Comparative analysis of velopharyngeal activity assessed by acoustic rhinometry and rhinomanometry.

PURPOSE: To analyze the velopharyngeal (VP) activity of subjects with velopharyngeal dysfunction (VPD) by acoustic rhinometry, as compared to rhinomanometry. METHODS: This was a prospective clinical study conducted in 41 adults, both genders, with repaired cleft palate, with or without a previously repaired cleft lip, and residual VPD on clinical assessment, without compensatory articulations for [p], [t], and [k]. The outcome measures were as follows: (1) on acoustic rhinometry, nasopharyngeal volumetric change (ΔV) during [p], [t], and [k], relatively to rest condition (decreases by <3 cm3 considered as absence of VP activity); (2) on modified anterior rhinomanometry, VP orifice area (areas ≥0.05 cm2 considered as inadequate closure). The plosive [p] was used when comparing the techniques (n=24). RESULTS: (1) A mean ΔV decrease of 18% was observed during [k], which was significantly lower (p<0.05) than the decrease reported for individuals without VPD (30%). ΔV values suggesting VPD were observed in 59% subjects. Similar results were obtained for [p] and [t], which shall be used as stimulus, given that they do not involve the use of the tongue to lift the velum during VP closure, differently from the velar plosive [k]. (2) Inadequate closure was seen in 85% subjects. No correlation was observed between ∆V and VP orifice area. Agreement between techniques was observed in 51% cases. CONCLUSION: Acoustic rhinometry had low accuracy as a diagnostic method of VPD when compared to the gold standard method. Nevertheless, the technique shows potential as a method for monitoring the outcomes of clinical and surgical treatment of VPD aimed at increasing velar and pharyngeal activity.
