Clefts of the lip and palate frequently produce nasal deformities that tend to reduce the size of the nasal airway. Approximately 70% of the cleft population have nasal airway impairment and about 80% “mouth-breathe” to some extent. Surgical correction of nasal, palatal, and pharyngeal structures may further compromise breathing. Type of cleft appears to affect airway size, with unilateral clefts demonstrating the smallest airway. Although a pharyngeal flap may further decrease airway size, some individuals do not notice a postoperative change because of airway compromise prior to flap placement. Speech is a modified breathing behavior that uses the respiratory system to provide an energy source and involves structures within the respiratory tract to modulate this energy into meaningful sounds. The oral, nasal, and pharyngeal structures that are affected by cleft lip and palate during breathing are often compromised for speech as well. The nasal airway plays an important role in controlling speech pressures when velopharyngeal function is impaired. A “good” nose for breathing is often a “bad” nose for speech under such circumstances.

Objective The purpose of this study was to investigate a new diagnostic method that provides an approach to noninvasive, objective measurement of velopharyngeal movement by acoustic determination of epipharyngeal volume changes with velopharyngeal muscle function. Design This was a case control study, using consecutive samples. Setting This study took place at the Cleft Palate Rehabilitation Center of the University of Mainz, Germany. Patients Subjects were 29 consecutive cleft lip and palate (CLP) patients and 31 controls (21 patients with dysgnathia and 10 healthy volunteers). Intervention A series of transnasal acoustic measurements (pressure wave: 55 dB for 2 milliseconds) of epipharyngeal volume were performed with the pharyngeal muscles relaxed in end-expiration and while the velopharyngeal orifice was closed, with the difference in volume representing maximal pharyngeal movement. Results Cleft palate patients yielded significantly lower values of velopharyngeal movement (6.5 cm3) than did the control group (8.0 cm3)(p < .05; Mann-Whitney U test). Overlapping ranges of values were measured for the C(L)P and control groups. The least mobility (4.75 cm3) was measured in patients who had undergone pharyngeal flap surgery. Different patterns of restriction were observed in patients with and without a pharyngeal flap. Conclusion Acoustic pharyngometry may provide access to noninvasive quantitative measurement of velopharyngeal movement and a better understanding of the pattern of movement in C(L)P-patients. We expect it to be a helpful tool in objectively monitoring the progress of logopedic therapy.

The aim was to evaluate whether a large adenoid, which aids velopharyngeal function, influences facial growth and if a pharyngeal flap reinforces the effect. Forty cleft palate patients were divided into two groups: adenoid and nonadenoid. Twenty of the patients had a pharyngeal flap operation. All the patients had three cephalograms taken at the same ages over a period of 5 years. At an average age of 4.7 years, i.e., one year before any pharyngoplasty, the mandibular inclination was larger in the adenoid group. This inferioposterior mandibular position was aggravated when a flap was added and with age. The present study suggests that the nasopharyngeal space, which is indicative of nasal airway patency, is influenced by a pharyngeal flap as well as an adenoid which, in turn, influences facial growth direction in the cleft palate population. Airway variables ought to be taken into consideration when the growth effect of cleft palate treatment is evaluated.

Objective: To provide speech outcomes of English-speaking Ugandan patients with a cleft palate with or without cleft lip (CP±L). Design: Prospective case–control study. Setting: Referral hospital for patients with cleft lip and palate in Uganda. Participants: Twenty-four English-speaking Ugandan children with a CP±L (15 boys, 9 girls, mean 8.4 years) who received palatal closure prior to 6 months of age and an age- and gender-matched control group of Ugandan children without cleft palate. Interventions: Comparison of speech outcomes of the patient and control group. Main Outcome Measures: Perceptual speech outcomes including articulation, resonance, speech understandability and acceptability, and velopharyngeal composite score (VPC-sum). Information regarding speech therapy, fistula rate, and secondary surgery. Results: Normal speech understandability was observed in 42% of the patients, and 38% were judged with normal speech acceptability. Only 16% showed compensatory articulation. Acceptable resonance was found in 71%, and 75% of the patients were judged perceptually to present with competent velopharyngeal function based on the VPC-sum. Additional speech intervention was recommended in 25% of the patients. Statistically significant differences for all these variables were still observed with the control children ( P < .05). Conclusions: Overall, acceptable speech outcomes were found after early primary palatal closure. Comparable or even better results were found in comparison with international benchmarks, especially regarding the presence of compensatory articulation. Whether this approach is transferable to Western countries is the subject for further research.

Cleft lip and palate is the most frequent birth anomaly, with increasing reported rates of complications, such as palate fistulae. Current studies concerning the occurrence rate of cleft lip and palate (CLP) report 2 to 10 cases in 10,000 births. The purpose of this study was to investigate the existence of factors that could predict the occurrence of fistulae after cleft lip and palate surgery. A retrospective study was performed by collecting and analyzing data from all patients who were operated for cleft lip and/or palate in the Maxillo-Facial Department of the Emergency Clinical County Hospital of Cluj-Napoca, Romania, between 2010 and 2020. We investigated the existing evidence for possible links between the number of fistulae observed after the primary palatoplasty and the age at which the primary palatoplasty was performed, the sex of the patient, the type of cleft, the timing of the surgical corrections, and the presence of comorbidities. A total of 137 cases were included for analysis. A significant link between the number of fistulae and the type of cleft was found (with fistulae occurring more frequently after the surgical correction of CLP—p < 0.001). No evidence was found for the existence of significant links between the number of fistulae and the patient’s sex, the timing of surgery, or the presence of comorbidities. This study concluded that the incidence of palatal fistulae appears to be influenced by the type of cleft (CLP), but not by the sex of the patient, the timing of surgery, or the presence of comorbidities.

Cleft lip and palate are common congenital anomalies with significant implications for feeding, swallowing, and speech. If a cleft palate goes unrepaired, a child will have difficulty distinguishing nasal and oral sounds. Even following cleft palate repair, approximately 20 to 30% of nonsyndromic children have persistent hypernasal speech. This often occurs due to velopharyngeal dysfunction (VPD), a term describing failure of the soft palate and pharyngeal walls to seal the nasopharynx from the oropharynx during oral consonant production. The gold standard for diagnosis is perceptual examination by a trained speech pathologist, although additional diagnostic tools such as nasendoscopy are often used. Treatment options for VPD range from speech therapy to revision palatoplasty, sphincter pharyngoplasty, pharyngeal flap, and pharyngeal wall augmentation. Palatal prosthetics may also be considered for children who are not surgical candidates. Further research is needed to improve selection of diagnostic and treatment interventions and optimize speech outcomes for children with a history of oral cleft. This review contains 1 figure, 3 videos, and 58 references.  Key words: Cleft lip and palate, hypernasal resonance, levator veli palatine, nasal emission, nasendoscopy, palatoplasty, pharyngeal flap, posterior pharyngeal wall augmentation, sphincter pharyngoplasty, velopharyngeal dysfunction

Objectives The aim was to study the relationship between perceptual evaluation of speech variables related to velopharyngeal function and the pattern of nasal airflow during the velopharyngeal closing phase in speech in children with and without cleft palate. Participants Fourteen children with cleft lip and palate or cleft palate only and 15 controls aged 7 and 10 years. All were native Swedish speakers. Method Three experienced listeners performed a blinded perceptual speech evaluation. Nasal airflow was transduced with a pneumotachograph attached to a nasal mask. The duration from peak to 5% nasal airflow, maximum flow declination rate, and nasal airflow at selected points in time during the transition from nasal to stop consonants in bilabial and velar articulatory positions in sentences were estimated. The analysis was focused on the perceptual ratings of “velopharyngeal function” and “hypernasality.” Results A strong association was found between ratings of “velopharyngeal function” and “hypernasality” and the pattern of nasal airflow during the bilabial nasal-to-stop combination /mp/. Both the sensitivity and specificity were 1.00 for the bilabial temporal airflow measure in relation to ratings of “velopharyngeal function.” The nasal airflow rate during /p/ in /mp/ had a sensitivity of 1.00 and specificity of 0.92 to 0.96 in relation to ratings of “hypernasality.” Conclusion Assessment of the nasal airflow dynamics during the velopharyngeal closing phase in speech presents quantitative, objective data that appear to distinguish between perceptually normal and deviant velopharyngeal function with high sensitivity and specificity.

Aim: To examine the association of cleft severity at infancy and velopharyngeal competence in preschool children with unilateral cleft lip and palate operated with early or delayed hard palate repair. Design: Subgroup analysis within a multicenter randomized controlled trial of primary surgery (Scandcleft). Setting: Tertiary health care. One surgical center. Patients and Methods: One hundred twenty-five infants received cheilo-rhinoplasty and soft palate repair at age 3 to 4 months and were randomized to hard palate closure at age 12 or 36 months. Cleft size and cleft morphology were measured 3 dimensionally on digital models, obtained by laser surface scanning of preoperative plaster models (mean age: 1.8 months). Main outcome measurements: Velopharyngeal competence (VPC) and hypernasality assessed from a naming test (VPC-Sum) and connected speech (VPC-Rate). In both scales, higher scores indicated a more severe velopharyngeal insufficiency. Results: No difference between surgical groups was shown. A low positive correlation was found between posterior cleft width and VPC-Rate (Spearman = .23; P = .025). The role of the covariate “cleft size at tuberosity level” was confirmed in an ordinal logistic regression model (odds ratio [OR] = 1.17; 95% confidence interval [CI]:1.01-1.35). A low negative correlation was shown between anteroposterior palatal length and VPC-Sum (Spearman = −.27; P = .004) and confirmed by the pooled scores VPC-Pooled (OR = 0.82; 95% CI: 0.69-0.98) and VPC-Dichotomic (OR = 0.82; 95% CI: 0.68-0.99). Conclusions: Posterior cleft dimensions can be a modest indicator for the prognosis of velopharyngeal function at age 5 years, when the soft palate is closed first, independently on the timing of hard palate repair. Antero-posterior palatal length seems to protect from velopharyngeal insufficiency and hypernasality. However, the association found was significant but low.

Objective: To test the reliability of the speech data in the Swedish quality registry for cleft lip and palate. Design: Retrospective study. Setting: Primary care university hospital. Participants: Ninety-four children born with cleft palate with or without cleft lip between 2005 and 2009 who had been assessed and registered in the quality registry at the age of 5 years. Main Outcome Measures: Data in the registry on percent oral consonants correct, percent oral errors, percent nonoral errors, perceived velopharyngeal function (PVPF), and intelligibility were compared with results based on reassessments by 3 independent raters from audio recordings. Agreement was calculated by the intraclass correlation coefficient (ICC), quadratic weighted kappa, and percentage agreement. Results: Absolute agreement calculated by average measures ICC for percent oral consonants correct, percent oral errors, and percent nonoral errors was above >0.90. Single measures ICC for percent oral consonants correct was 0.82, for percent oral errors 0.69, and for percent nonoral errors 0.83. The kappa coefficient for PVPF was 0.5 to 0.59 and for intelligibility 0.65 to 0.77. Exact percentage agreement for PVPF was 33% and for intelligibility 47.8%. Conclusions: The data on oral consonants correct and nonoral errors in the quality registry seem to be reliable. The data on oral errors, PVPF, and intelligibility should be interpreted with caution. If differences among treatment centers are detected, one should go back and examine the collected raw data before drawing any definitive conclusions about treatment outcome.
