Results of Primary Repair of Submucous Cleft Palate with Furlow Palatoplasty in Both Syndromic and Nonsyndromic Children

Comparison of Speech Outcomes Between Speech Therapy Only and Double-Opposing Z-Plasty Combined With Speech Therapy in Patients With Submucous Cleft Palate

The purpose of this study was to compare speech outcomes in patients with submucous cleft palate (SMCP) between speech therapy alone and double-opposing Z-plasty (DOZ) combined with speech therapy. The subjects were 67 patients with SMCP (overt type, 45 males, 22 females), who were divided into the observation group (n=18), the speech therapy group (n=24; duration, 17.8 mo), and the DOZ and speech therapy (DOZ-speech therapy) group (n=25; median age at DOZ, 5.3 years, duration, 18.6 mo). The median age at initial and final speech assessments were 3 and 5 years. After age, sex, syndromic status, duration of speech therapy, surgery timing, and speech outcomes were investigated, statistical analysis was performed. After tailored interventions, both isolated and non-isolated SMCP patients experienced significant improvements in speech outcomes, including nasal emission, hypernasality, compensatory articulation, and unintelligible speech. Since comparable improvements were observed, there were no significant differences in the final assessments regardless of initial speech issues between the speech therapy group and the DOZ-speech therapy group (all P>0.05). In the DOZ-speech therapy group, the rate of achieving "socially acceptable" speech was 92.3% in isolated cases and 90% in non-isolated cases. Multivariate analysis revealed that DOZ showed a tendency to reduce hypernasality, compensatory articulation, and "unintelligible" speech; syndromic or developmental conditions influenced outcomes in nasal emission and hypernasality; and initial hypernasality and compensatory articulation were correlated with outcomes. Therefore, DOZ surgery could be recommended to resolve hypernasality and compensatory articulation in SMCP patients before speech issues worsen.

What Technique Results in the Lowest Rate of Velopharyngeal Insufficiency in Patients With Submucous Cleft Palate? A Systematic Review and Meta-Analysis

Objective: To determine which surgical technique offers the lowest rate of velopharyngeal insufficiency (VPI) without the need for further operative intervention, in pediatric patients with nonsyndromic submucous cleft palate (SMCP). Methods: This systematic review and meta-analysis included articles reporting on nonsyndromic pediatric patients treated surgically during childhood for SMCP, with data on postoperative speech outcomes and/or recommendations for secondary surgery. Main outcome measures included rates of unfavorable speech outcomes defined as persistent VPI requiring secondary surgery and speech outcome data. Results: 15 articles met our inclusion criteria, reporting on 383 children who underwent surgical treatment; 343 patients were included in studies reporting recommendations for secondary surgery. There was 1 randomized comparative trial, 4 comparative studies, and 10 single cohort studies. Eight articles used validated speech assessment tools. Our model showed the proportion of patients recommended for secondary surgery varied between techniques, ranging from 0.0% (CI 0.0, 1000) in pharyngeal flap to 17.8% (CI 8.9, 32.5) in straight line repair techniques, but there was no statistically significant difference between treatments (P = .33). Speech improvement ranged from 44.4% to 100%, with 9 studies recommending secondary surgery for some of their patient series. Conclusions: Although not of statistical significance, pharyngeal flap yields the lowest rate of reoperation as a primary technique for pediatric patients with nonsyndromic SMCP. Delayed repair age inherent to SMCP may render operations that rely on a functional levator muscle with less favorable outcomes. The absence of standardized surgical techniques, speech outcomes, speech therapy, and assessment make comparative analysis and recommendation difficult. We advocate for standardized speech assessment tools to improve future quantitative assessment of cleft surgery outcomes and a randomized controlled trial to better elucidate the preferred first-line technique.

Prognostic Factors for Speech Outcome among Patients with Submucous Cleft Palate Managed by Furlow Palatoplasty or Posterior Pharyngeal Flap

BACKGROUND

Submucous cleft palate (SMCP) is a particular subtype of cleft deformity for which the optimal surgical timing and technique are still under debate. This study aimed to identify potential prognostic factors for the speech outcome of patients with SMCP and provide evidence for further management strategy optimization.

METHODS

The authors reviewed patients with nonsyndromic SMCP who received either Furlow palatoplasty (FP) or posterior pharyngeal flap (PPF) between 2008 and 2021 in a tertiary hospital-based cleft center. Both univariate and multivariate logistic regression models were used to screen preoperative variables, including cleft type (overt or occult), age at surgery, mobility of velum and pharyngeal wall, velopharyngeal closure ratio, and pattern. The receiver operating characteristic curve was used to determine the cutoff value of the significant predictors for subgroup comparison.

RESULTS

A total of 131 patients were enrolled, with 92 receiving FP and 39 receiving PPF. Age at operation and cleft type were identified as having significant effects on FP outcome. Patients operated on before 9.5 years of age had a significantly higher velopharyngeal competence (VPC) rate than those operated on after that age. The speech outcome among patients with occult SMCP was significantly worse than that of patients with overt SMCP after FP treatment. No preoperative variable was found to be correlated with PPF outcome. PPF yielded a higher VPC rate than did FP among patients operated on after 9.5 years of age.

CONCLUSIONS

The prognosis of patients with SMCP treated with FP is sensitive to age at surgery and cleft type. PPF may be considered for older patients in settings with limited access to multiple surgical procedures, especially when occult SMCP is diagnosed.

Outcomes of Primary Furlow Double-Opposing Z-plasty for the Treatment of Symptomatic Submucous Cleft Palate

BACKGROUND

Submucous cleft palate (SMCP) requires surgical repair if symptomatic. The Furlow double-opposing Z-plasty is the preferred method in Helsinki cleft center.

AIMS

To assess the efficacy and complications of Furlow Z-plasty in the treatment of symptomatic SMCP.

METHODS

This retrospective study reviewed documentation of 40 consecutive patients with symptomatic SMCP who underwent primary Furlow Z-plasty by 2 high-volume cleft surgeons at a single center between 2008 and 2017. Patients underwent perceptual and instrumental evaluation of velopharyngeal function (VPF) by speech pathologists preoperatively and postoperatively.

RESULTS

The median age at Furlow Z-plasty was 4.8 years (SD 2.6, range 3.1-13.6). The overall success rate, including postoperative competent or borderline competent VPF, was 83%, and 10% required secondary surgery for residual velopharyngeal insufficiency. The success rate was 85% in nonsyndromic, and 67% in syndromic patients with no significant difference ( P =0.279). Complications arose in only 2 (5%) patients. No children were found to have obstructive sleep apnea postoperatively.

CONCLUSION

Furlow primary Z-plasty is a safe and effective operation for symptomatic SMCP with a success rate of 83% with only 5% rate of complications.

Speech Outcomes and Velopharyngeal Function in Children Undergoing Submucous Cleft Palate Repair

OBJECTIVE

Describe and compare the results of speech and velopharyngeal function in children with classic and occult submucous cleft palate undergoing interdisciplinary treatment at the Gantz Foundation.

METHODS

The clinical history of all patients born between 2012 and 2017 with a diagnosis of classic or occult submucous cleft palate was retrospectively reviewed. Preoperative and postoperative medical, surgical, and speech and language history were collected.

RESULTS

Twenty-eight cases diagnosed at the age of 44.8±23.9 months were included. Of these, 71.4% presented classic submucous cleft, and 28.6% occult. Before primary surgery, 7.1% had a diagnosis of the syndrome, and 21.4% were under study. A total of 39.3% had hearing difficulties and 21.4% used tympanic ventilation tubes. A total of 60.7% had language problems, 39.3% had compensatory articulation, 17.9% had absent hypernasality, and 21.4% had absent nasal emission. The team indicated primary palate surgery in 71.4%, of which 85% performed the surgery at the mean age of 61.7±24.7 months. The surgical technique was Furlow in 88.2% of the cases and intravelar veloplasty in the remaining 11.8%. Then, 3 cases underwent velopharyngeal insufficiency surgery; 2 of them eliminated hypernasality and reduced nasal emission. The age of diagnosis ( P =0.021) and the performance of velopharyngeal insufficiency surgery ( P =0029) of the occult submucous cleft palate group was significatively later than the classic cleft palate group.

CONCLUSIONS

Language, hearing, compensatory articulation, hypernasality, and nasal emission problems were recorded. A high percentage required primary surgery. Of these, a low proportion also required a velopharyngeal insufficiency surgery, which improved the velopharyngeal function of the children but did not completely adapt it. In this regard, early diagnosis is essential, as well as an analysis of each center primary closure protocol.

Surgical management in submucous cleft palate patients

OBJECTIVES

The submucous cleft palate (SMCP) is considered to be the most subtle type of cleft palate. Early detection is important to allow on time intervention by speech therapy and/or surgical repair before the children already develop compensatory speech mechanisms. The purpose of this study was to investigate at what time children with a SMCP present, to determine when children are operated, and to analyze the postoperative outcomes for in SMCP children.

PATIENT AND METHODS

Medical records from 766 individuals registered in the cleft registry in the Wilhelmina's Children's' Hospital, Utrecht, were retrospectively reviewed. Inclusion criteria were children diagnosed with SMCP. The following data were collected: age at diagnosis, physical examination, age at surgery, surgical technique, speech therapy pre- and post-surgery, otitis media, secondary cleft surgery, family history, syndromes, and other anomalies.

RESULTS

In total, 56 SMCP children were identified. The mean age of diagnosis was 44.0 months (range 0-150, SD = 37.0). In 48 children (85.7%), surgical intervention was performed (Furlow plasty, intravelar veloplasty, pharyngoplasty, or Furlow combined with buccal flap).

CONCLUSION

This retrospective study reconfirms that SMCP often presents late, even in a country with a modern healthcare system and adequate follow-up of all newborns by the so-called youth doctors in "children's healthcare centers" up to the age of 4 years old. Almost 86% of patients ultimately needed palate surgery when SMCP was suspected.

CLINICAL RELEVANCE

Any child presenting with repeated episodes of otitis media, nasal regurgitation, or speech difficulties should have prompt consideration for SMCP as diagnosis.

Outcomes of Furlow Double-Opposing Z-Plasty Palatoplasty for the Treatment of Symptomatic Overt and Occult Submucous Cleft Palate: A Comparison Study

BACKGROUND

The submucous cleft palate can be overt or occult and may require surgical repair. The double-opposing Z-plasty (Furlow repair) is the authors' center's preferred approach. This study evaluated complication rates, differences in outcome between overt and occult types, and patient factors associated with surgical failure.

METHODS

This retrospective study reviewed documentation on all patients who underwent Furlow Z-plasty for submucous cleft palate at a single center between 2004 and 2018. Speech pathology was quantified using the Pittsburgh Weighted Speech Score.

RESULTS

A total of 351 patients were included (125 overt and 226 occult cases). Furlow Z-plasty was successful (postoperative Pittsburgh Weighted Speech Score <7 without recommendation for secondary speech surgery) in 291 patients (82.1 percent). Apart from those requiring secondary surgery, there were no documented complications. Occult-type patients were 7.5 years old at palatoplasty with a speech score of 14.1; overt-type patients were 6.5 years old with a score of 15.7. Postoperative speech scores were similar for both groups. Secondary speech surgery patients had a higher preoperative score (16.9 versus 14.2). Age at time of palatoplasty and submucous cleft palate type were not predictive of the need for secondary surgery. Syndromic patients had higher preoperative and postoperative speech scores (15.6 and 7.5, respectively) than nonsyndromic patients (14.3 and 4.3) and needed secondary surgery more often (24.4 percent versus 9.2 percent). V-shaped velar vaulting on preoperative assessment was present in 92 percent of occult-type patients.

CONCLUSIONS

Furlow palatoplasty is a safe and effective means of repairing submucous cleft palate. Patients with the occult type presented later with a lower Pittsburgh Weighted Speech Score. High preoperative speech score and syndromic status were associated with the need for secondary speech surgery. V-shaped velar vaulting is a reliable sign of occult submucous cleft palate.

Clinical interventions and speech outcomes for individuals with submucous cleft palate

Background

This study aimed to identify the initial diagnostic characteristics and treatment status of children with submucous cleft palate (SMCP) and to examine the relationship between the timing of surgical correction and the degree of articulation and resonance improvement.

Methods

This retrospective study included 72 children diagnosed with SMCP between 2008 and 2016. The evaluation criteria were the age of the initial visit, total number of visits, age at the end of treatment, speech problems, resonance problems, and speech therapy.

Results

Children with SMCP first visited the hospital at an average age of 34.32 months, and speech problems were identified at an average age of 48.53 months. Out of 72 children, 46 underwent surgery at an average age of 49.74 months. Four of these children required secondary surgery at an average age of 83.5 months. Among the children who underwent surgery before 3 years of age, 70% exhibited articulation improvements, with mild-to-moderate hypernasality. Articulation improvements showed no statistically significant differences according to age at the time of surgery. However, children who underwent surgery before 4 years had a better hypernasality rating than those who underwent surgery after 4 years of age.

Conclusions

Children with SMCP tend to undergo delayed treatment because the anatomical symptoms in some children with SMCP are unclear, and surgical interventions are considered only after speech problems are clarified. Starting interventions as early as possible reduces the likelihood of receiving secondary surgery and speech therapy, while increasing expectations for positive speech function at the end.

A Comparative Study Evaluating Speech Outcomes in Classic versus Occult Submucous Cleft Palate Using a Primary Furlow Palatoplasty Technique

BACKGROUND

No consensus exists on the selection of procedures for the treatment of submucous cleft palate, with scarce reports on long-term outcomes from single-surgeon experience. This study assessed the outcomes of using extended indication criteria of Furlow palatoplasty as the first-line procedure for the management of submucous cleft palate-associated velopharyngeal insufficiency.

METHODS

Consecutive nonsyndromic patients with submucous cleft palate (n = 216) treated by a single surgeon between 1998 and 2018 were reviewed. Furlow palatoplasty was performed in all patients diagnosed with submucous cleft palate-associated velopharyngeal insufficiency, regardless of the age cutoff, number of Calnan triad features, or velopharyngeal gap size and pattern. Postoperative velopharyngeal function outcome (adequate, marginal, or inadequate) and the need for secondary surgery were investigated. Age at surgery, sex, submucous cleft palate type (classic and occult), and presence of complication were evaluated for potential associations with this outcome.

RESULTS

Forty-seven patients aged 8.3 ± 4.6 years with occult submucous cleft palate were significantly (p < 0.001) older than those with the classic type (n = 169; 5.6 ± 3.1 years). Most (p < 0.001) of the included patients [n = 181 (83.8 percent)] achieved adequate postoperative velopharyngeal function outcome. Three patients (1.4 percent) presented surgery-related complications, including bleeding and partial wound disruption. Secondary speech surgery was recommended in 24 patients (11.1 percent). In the bivariate and multivariate analyses, none of the tested variables was found to be associated (all p > 0.05) with the postoperative velopharyngeal function outcome.

CONCLUSION

The extended indication criteria of Furlow palatoplasty provided adequate velopharyngeal insufficiency management with a low complication rate and satisfactory speech outcome.

Submucous Cleft Palate Repair in Patients With 22q11.2 Deletion Syndrome

OBJECTIVE

To determine whether surgical intervention for submucous cleft palate (SMCP) is more common in children with 22q11.2 deletion syndrome (22q DS) compared to children without 22q DS.

DESIGN

Retrospective chart review.

SETTING

Tertiary pediatric hospital and 22q11.2 DS specialty clinic.

PARTICIPANTS

One hundred forty-two children seen at the tertiary hospital or clinic during a 20-year period (June 1999-June 2019) with documented SMCP with and without 22q DS.

MAIN OUTCOME MEASURE

Percentage of children with SMCP with and without 22q DS requiring surgical intervention for velopharyngeal insufficiency.

RESULTS

Patients with 22q DS had a significantly higher frequency of SMCP repair than those without 22q DS (89.7% vs 32.0%, P < .001, χ² = 37.75). The odds of requiring SMCP repair were 18.6 times higher in those with 22q DS compared to those without (odds ratio = 18.6, CI = 6.1-56.6).

CONCLUSIONS

This study provides new evidence suggesting patients with 22q DS require SMCP surgical repair for velopharyngeal insufficiency at a significantly higher rate than those without 22q DS. As the majority of patients with 22q DS with SMCP require surgical intervention, future prospective studies looking at early versus late repair of SMCP in patients with 22q DS are needed to guide the surgical repair timeline in this population.

Speech and language characteristics in individuals with nonsyndromic submucous cleft palate-A systematic review

BACKGROUND

Up to 80% of individuals with unrepaired submucous cleft palate (SMCP) experience speech difficulties secondary to velopharyngeal insufficiency. Language delays are reported in the broader cleft lip and/or palate population, suggesting that individuals with SMCP may also be at risk. However, contemporary understanding of this population remains limited as there has been no systematic examination of the literature. This review aims to systematically review and document the speech and language characteristics of individuals with nonsyndromic SMCP and, in addition, to identify factors reported to impact speech and language outcomes.

METHOD

This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Five databases were comprehensively searched using keywords and indexed headings. Included studies had to report speech or language outcomes of individuals with nonsyndromic SMCP. Risk of bias and methodological design quality were examined using tools from the Scottish Intercollegiate Guidelines Network. Relevant data were extracted for analysis.

RESULTS

Eighteen studies met inclusion criteria, yielding 598 participants. Study results showed that individuals with unrepaired nonsyndromic SMCP may have speech difficulties secondary to velopharyngeal insufficiency including increased nasal resonance and palatalized or glottal articulation. Lower age at primary surgical repair led to better postsurgical speech outcomes. There is a paucity of literature outlining motor or phonological aspects of speech and receptive or expressive language abilities of this population.

CONCLUSION

Individuals with nonsyndromic SMCP present with speech difficulties similar to those experienced by individuals with overt cleft palate. Health care professionals should be aware of possible presenting symptoms and consider early SMCP diagnoses where appropriate. Further research is needed to specify the broader communication profile in this population.

Effects of Surgical Intervention and Continuous Positive Airway Pressure Therapy on Velopharyngeal Structure and Function: A Case Report

Changes to the velum and velopharyngeal muscles following Furlow double-opposing Z-plasty in a 7-year-old female with submucous cleft palate and velopharyngeal dysfunction (VPD) were evaluated. Perceptual, instrumental (ie, nasometry and aerodynamic pressure flow), and research magnetic resonance imaging analyses were used during pre- and postsurgical time points at a university research clinic. Continuous positive airway pressure (CPAP) therapy was trialed following a failed surgery for residual VPD in the patient. Increases in velar length and thickness and decreases in levator veli palatini muscle angle of origin and contraction were observed following the Furlow double-opposing Z-plasty surgery. Variable improvements in residual hypernasality following the home-based CPAP therapy protocol were observed.

A Treatment Protocol for Velopharyngeal Insufficiency and the Outcome

BACKGROUND

A simple algorithm is applied to treat velopharyngeal insufficiency. The purpose of this study was to assess its success rate and complications.

METHODS

The diagnosis includes speech perceptual assessment and nasopharyngoscopy, focusing on velopharyngeal closure ratio. The treatment is composed of a double-opposing Z-plasty for marginal velopharyngeal insufficiency or a pharyngeal flap for moderate to severe velopharyngeal insufficiency. A retrospective chart review was conducted for 84 consecutive nonsyndromic postpalatoplasty patients undergoing velopharyngeal insufficiency surgery from August of 2007 to December of 2014. The demographic, perioperative, and follow-up data were collected. Statistical analyses were performed.

RESULTS

Mean age at velopharyngeal insufficiency surgery was 7.0 years. The overall improvement rate for patients was 86.9 percent. Nine patients in the double-opposing Z-plasty group and two patients in the pharyngeal flap group were refractory to velopharyngeal insufficiency surgery. The improvement rates for each surgical group were 80.4 percent for the double-opposing Z-plasty group and 94.7 percent for the pharyngeal flap group. There were no significant differences in postoperative velopharyngeal function between the coronal and noncoronal groups. Airway-associated complications were observed in nine patients (10.7 percent). The complications in the double-opposing Z-plasty group were observed in two patients (4.3 percent), and none of the patients presented obstructive sleep apnea. Seven patients (18.4 percent) in the pharyngeal flap group showed postoperative snoring, and one (2.6 percent) of them presented with obstructive sleep apnea.

CONCLUSION

The authors' algorithm is a simple patient- and surgeon-friendly strategy to obtain satisfactory improvement of velopharyngeal function for velopharyngeal insufficiency patients, with a low risk of airway complications.
