Surgical management in submucous cleft palate patients

Soft Palate Dysplasia: Properties and Surgical Techniques

BACKGROUND

The authors aimed to report a hitherto undescribed class of patients with the obvious phenotype of a novel soft palate dysplasia (SPD) combining unilateral soft palate hypoplasia with a fully developed uvula. The authors also aimed to investigate and evaluate the corresponding surgical approaches.

METHODS

Twelve patients were clinically diagnosed with SPD. Clinical examination, including radiographic tests, was performed to characterize the congenital deformity. The effectiveness of velopharyngeal closure and speech were tested preoperatively and postoperatively.

RESULTS

SPD was featured with velopharyngeal insufficiency, food regurgitation, and speech disorders. It was commonly manifested as structural deformities of the soft palate, tongue palatine arch, pharyngeal palatine arch, and pterygomandibular fold, but with complete uvula shape. According to radiographic analysis, in five patients, the lateral pterygoid processes were poorly developed, and other malformations were present. Velopharyngoplasty based on the unilateral posterior pharyngeal flap can well restore the velopharyngeal closure and speech intelligibility without respiration obstruction.

CONCLUSIONS

SPD is characterized as congenital velopharyngeal insufficiency manifested as a primary soft palate defect. It is highly associated with other physical deformities but independent of conventionally known syndromes. The cause may be an abnormal development of the pterygoid process. Unilateral velopharyngoplasty based on the posterior pharyngeal flap is a great technique to repair SPD.

Outcomes of primary repair of cleft palate using sommerled intravelar veloplasty associated with velocardiofacial syndrome

OBJECTIVES

Velocardiofacial syndrome, a prevalent microdeletion syndrome occurring in 1 in 2000-4000 live births, is marked by speech and language disorders, notably velopharyngeal dysfunction. This study investigates speech outcomes, nasometric and videofluoroscopic results before and after primary repair of cleft palate using the Sommerlad intravelar veloplasty (SIVV) technique within the Isfahan cleft care team for patients with velocardiofacial syndrome.

METHODS

Employing a quasi-experimental design, 19 participants with velocardiofacial syndrome, who underwent primary cleft palate repair by the Isfahan cleft care team, were included through convenience sampling. Perceptual and instrumental outcomes were assessed pre-and post-operatively. Statistical analysis encompassed paired t-tests and the non-parametric Wilcoxon signed-rank test (p < 0.05).

RESULTS

The study identified no statistically significant differences between pre-and post-surgical speech outcome parameters and nasalance scores. Nonetheless, a significant distinction emerged in the velopharyngeal closure ratio based on fluoroscopic evaluation (p = 0.038).

CONCLUSION

The efficacy of the SIVV technique in treating velopharyngeal dysfunction in velocardiofacial syndrome patients is inconclusive, demanding further research. Post-surgical speech outcomes are influenced by surgical technique, hypotonia, apraxia of speech, and surgery timing. Notably, an elevated velopharyngeal valve closure ratio, though anatomically indicative, does not exclusively predict surgical success.

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.

[Cleft lip and palate : One of the most frequent congenital malformations]

With a frequency of 1 per 500 live births, a cleft lip and palate is one of the most frequent congenital malformations. Untreated, it leads to disturbances in feeding, speech, hearing, tooth position and esthetics. A multifactorial genesis is assumed. The fusion of the different facial processes takes place in the first 3 months of pregnancy and a cleft can develop during this time. Surgical treatment includes the early anatomical and functional restoration of the affected structures within the first year of life in order to enable normal intake of food, articulation, nasal breathing and middle ear ventilation. Breastfeeding is possible in children with a cleft formation but alternative feeding methods, such as finger feeding, often have to be used. In addition to the surgery for primary closure of the cleft, otorhinolaryngological (ENT) interventions, speech therapy, orthodontic treatment as well as other surgical interventions are part of the interdisciplinary treatment concept.

A retrospective analysis of speech and hearing in patients receiving surgery for submucous cleft palate

Submucous cleft palate (SMCP) is an uncommon subtype of cleft palate that is associated with symptoms of velopharyngeal insufficiency (VPI), the most common being hypernasal speech. A high proportion of patients also suffer from conductive hearing loss, which is thought to be due to eustachian tube dysfunction. A number of surgical techniques have been proposed to correct the anatomical defect that is responsible for VPI. This exploratory study aims to describe surgical techniques and clinical outcomes in a series of patients who underwent surgical repair of SMCP at a single regional specialist cleft centre between 1999 and 2018. Through a retrospective case note review, records of 57 patients who underwent SMCP repair between the ages of 6 months and 16 years were examined. Patients underwent one of the three surgical techniques: Intravelar Veloplasty, Furlow or a novel technique we have termed as "Hemi-Furlow". Hypernasality, measured on the Great Ormond Street Speech Assessment, showed evidence of improvement post-operatively in all three surgical groups (P<0.005), with no evidence to favour any specific approach. Post-operative complications, including wound dehiscence and fistulae, occurred in nine patients (15.8%). Nine patients (15.8%) required revisional surgery, either due to post-operative complications or persistent speech problems. Otological disease was present in 54.4% of patients, comprising conductive hearing loss due to otitis media with effusion (52.6%) and sensorineural hearing loss (1.8%). There is now a need for large, multi-centre studies with robust outcomes measures to further examine relationships between surgical techniques and clinical outcomes in people born with SMCP.
