Investigating the Effects of Glottal Stop Productions on Voice in Children With Cleft Palate Using Multidimensional Voice Assessment Methods

Treatment Outcomes of Interdisciplinary Care on Speech and Health-Related Quality of Life Outcomes in Adults With Cleft Palate

PURPOSE

Individuals born with a cleft palate with or without a cleft lip (CP ± L) often experience functional, aesthetic, and psychosocial consequences well into adulthood. This study aimed to investigate outcomes of speech and health-related quality of life (HRQoL) in adults with a CP ± L who received interdisciplinary cleft care at the Ghent University Hospital using valid, reliable, and condition-specific instruments.

METHOD

Thirteen Belgian Dutch-speaking participants with a CP ± L with a mean age of 25.4 years (SD = 5.1, range: 20-33 years) and an age- and gender-matched control group of 13 participants without a CP ± L with a mean age of 25.2 years (SD = 4.8, range: 20-32 years) were included in this study. Speech characteristics were evaluated perceptually and instrumentally. HRQoL was assessed through standardized patient-reported outcome measures. Outcomes were compared with those of the control group and to normative data where available.

RESULTS

Participants with a CP ± L in this sample demonstrated significantly lower speech acceptability (p < .001) and higher rates of hypernasality (p = .015) and nasal turbulence (p = .005) than the control group. They showed significantly higher satisfaction with appearance of the cleft scar compared with norms of adults with a CP ± L (p = .047). No other differences in speech characteristics, sociodemographics, or HRQoL were found between participants with and without a CP ± L.

CONCLUSIONS

The reduced speech acceptability and the presence of resonance and nasal airflow disorders may indicate the need for standardized long-term outcome measurement and interdisciplinary follow-up for speech characteristics and velopharyngeal insufficiency in young and middle adulthood in future clinical practice. Additional research is necessary to further substantiate these findings and to determine predictors for these continuing complications in adults with a CP ± L.

Compensatory Articulation Errors in Patients With Velopharyngeal Dysfunction and Palatal Anomalies

PURPOSE

The aim of this study was to assess the frequency and types of compensatory articulations (CAs) in nonsyndromic patients with velopharyngeal dysfunction (VPD) and various palatal anomalies and to determine the relationship between the frequency of CAs, type of palatal anomaly, and phonological errors.

METHOD

A total of 783 nonsyndromic, Hebrew-speaking patients with VPD and various palatal anomalies (cleft lip and palate [CLP], cleft palate [CP], submucous CP [SMCP], occult submucous CP [OSMCP], or non-CP) were studied retrospectively. Perceptual VPD tests, including articulation and phonological assessment, were conducted. CAs were described as below the level of the defect in the vocal tract (abnormal backing of oral targets to post-uvular place) or in front of it within the oral cavity (palatalization) and at the velopharyngeal port.

RESULTS

Among 783 patients, 213 (27.2%) had CAs. Most CAs (18.4%) occurred below the level of the defect, followed by CAs at the velopharyngeal port (12.0%) or in front of it (4.9%). No differences were found in the frequency of CAs between patients with CP (47.8%) or CLP (52.6%) and between those with non-CP (13.6%) or OSMCP (14.7%). SMCP patients had lower frequency of CAs (29.8%) than CP (p = .003) and CLP (p =  .002) patients but higher frequency than OSMCP (p = .002) and non-CP (p =  .002) patients did. Among the 783 patients, 247 (31.5%) had phonological errors. A higher frequency of phonological errors was found in patients with CAs (55.4%) compared to those without (22.6%) and in all palatal anomaly groups except CLP (31.4% vs. 23.9%).

CONCLUSIONS

CAs in nonsyndromic patients with VPD remained relatively high in all age groups, up to adulthood. CAs are influenced by inadequate velar length following palatal repair, as well as by oral structural abnormalities, whereas poor muscle function due to OSMCP and/or abnormal size and/or shape of nasopharynx has less influence. Errors produced in front of the velopharyngeal port are influenced by the structural anomaly of CLP. This information may contribute to general phonetic and phonological theories and genetic investigations about CP anomalies.

Subjective and Objective Evaluation of Speech in Adult Patients with Unrepaired Cleft Palate

OBJECTIVE

To explore the speech outcomes of adult patients through subjective perception evaluation and objective acoustic analysis, and to compare the differences in pronunciation characteristics between speakers with adult patients with unrepaired cleft palate and their non-cleft peers.

PARTICIPANTS AND INTERVENTION

Subjective evaluation indicators included speech intelligibility, nasality, and consonant missing rate, whereas objective acoustic parameters included normalized vowel formants, voice onset time, and the analysis of three-dimensional spectrogram and spectrum, were carried out on speech samples produced by 2 groups of speakers: (a) speakers with unrepaired cleft palate (n = 65, mean age = 25.1 years) and (b) typical speakers (n = 30, mean age = 23.7 years).

RESULTS

Compared with typical speakers, individuals with unrepaired cleft palate exhibited a lower speech intelligibility with higher nasality and consonant missing rate, the missing rate is highest for the 6 consonants syllables. The acoustic parameters are mainly manifested as differences in vowel formants and voice onset time.

CONCLUSIONS

The results revealed important acoustical differences between adult patients with unrepaired cleft palate and typical speakers. The trend of spectral deviation may have contributed to the difficulty in producing pressure vowels and aspirated consonants in individuals with speech disorders related to cleft palate.

The effect of velopharyngeal insufficiency on voice quality in Estonian Children with Cleft Palate

Most children born with cleft palate (CP) or cleft lip and palate (CL/P) have velopharyngeal insufficiency (VPI), some degree of hypernasal resonance, articulation disorders and laryngeal dysphonia. Combination of different CL/P specific problems may mask laryngeal dysphonia and therefore, it may remain undiagnosed and untreated by clinicians. The research aimed to study the effect of VPI on voice quality in Estonian CL/P children. We included 18 CL/P and 79 healthy children. Combination of objective (Multi-Dimensional Voice Program (MDVP)) and subjective (Pediatric Voice Handicap Index (pVHI), GRBAS scale, video-nasoendoscopy (VNE), video-laryngostroboscopy (VLS)) assessment methods were assisted and performed by our multidisciplinary cleft teams. We found that (1) overall quality of life is greatly affected by voice, resonance and articulation disorders in CL/P group, (2) more than half of the CL/P children had morphological changes of the vocal folds, (3) the severity of VPI did not result in worse outcomes of acoustic parameters of voice.

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.

Otologic, audiometric and speech findings in patients undergoing surgery for cleft palate

BACKGROUND

Although considerable progress has been made in the last 30 years in the treatment of cleft palate (CP), a multidisciplinary approach combining examinations by a paediatrician, maxillofacial surgeon, otolaryngologist and speech and language pathologist followed by surgical operation is still required. In this work, we performed an observational cross-sectional study to determine whether the CP grade or number of ventilation tubes received was associated with tympanic membrane abnormalities, hearing loss or speech outcomes.

METHODS

Otologic, audiometric, tympanometric and speech evaluations were performed in a cohort of 121 patients (children > 6 years) who underwent an operation for CP at the Vall d'Hebron Hospital, Barcelona from 2000 to 2014.

RESULTS

The most and least frequent CP types evaluated according to the Veau grade were type III (55.37%) and I (8.26%), respectively. A normal appearance of the membrane was observed in 58% individuals, of whom 55% never underwent ventilation ear tube insertion. No statistically significant associations were identified between the CP type and number of surgeries for insertion of tubes (p = 0.820). The degree of hearing loss (p = 0.616), maximum impedance (p = 0.800) and tympanic membrane abnormalities indicative of chronic otitis media (COM) (p = 0.505) among examined patients revealed no statistically significant association with the grade of CP. However, an association was identified between hypernasality and the grade of CP (p = 0.053), COM (p = 0.000), hearing loss (p = 0.000) and number of inserted ventilation tubes.

CONCLUSION

Although the placement of tympanic ventilation tubes has been accompanied by an increased rate of COM, it is still important to assess whether this is a result of the number of ventilation tubes inserted or it is intrinsic to the natural history of middle ear inflammatory disease of such patients. Our results do not support improvements in speech, hearing, or tympanic membrane abnormalities with more aggressive management of COM with tympanostomy tubes.

Voice Quality in Adults Treated for Unilateral Cleft Lip and Palate: Long-Term Follow-Up After One- or Two-Stage Palate Repair

OBJECTIVES

The aim of the current study was to assess voice quality among adults treated for unilateral cleft lip and palate (UCLP), after one- or two-stage palate closure, and compare it to a noncleft control group.

STUDY DESIGN

Cross-sectional study of patients with UCLP with long-term follow-up and noncleft controls.

PARTICIPANTS

Patients with UCLP born between 1960 and 1987, treated at Uppsala University Hospital, Sweden, were examined (n = 73) at a mean of 35 years after primary surgery. Forty-seven (64%) patients had been treated with 1-stage palate closure and 26 with 2-stage closure (36%). The noncleft control group consisted of 63 age-matched volunteers.

MAIN OUTCOME MEASURES

Ratings of perceptual voice characteristics from blinded voice recordings with Swedish Voice Evaluation Approach method. Acoustic voice analysis including pitch and spectral measures.

RESULTS

Among the patients, the mean values for the 12 evaluated variables on a visual analog scale (0 = no abnormality, 100 = maximal abnormality) ranged between 0.1 and 17, and the mean for all was 6 mm. Voice variables were similar between patients and controls, except the total mean of all the perceptual voice variables, as well as "vocal fry"; both slightly lower among patients ( P = .018 and P = .009). There was no difference in any variable between patients treated with 1-stage and 2-stage palate closure. No clear relationship was found between velopharyngeal insufficiency and dysphonia.

CONCLUSIONS

The voice characteristics among adults treated for UCLP in childhood are not different from those of individuals without cleft.
