Early or delayed palatoplasty in complete unilateral cleft lip and palate patients? A systematic review of the effects on maxillary growth

Buccal Fat Pad in Primary and Secondary Cleft Palate Repair: A Systematic Review of the Literature

ObjectiveTo review the evidence supporting the use of buccal fat pad (BFP) in primary and secondary cleft palate repair and its short- and long- term clinical outcomes.DesignSystematic review conducted by 2 independent reviewers following PRISMA guidelines.Setting: None ParticipantsArticles were identified from three databases (Pubmed/Medline, Embase and Web of Science). Search terms included "cleft palate", "palatoplasty", "palate repair", "buccal fat pad".InterventionsUse of BFP in primary and secondary cleft palatoplasty.Main Outcome MeasuresPrimary outcomes were immediate postoperative complications, postoperative fistula, and maxillary growth. Secondary outcomes were palatal length, speech, and donor site morbidity.ResultsNinety-one reports were retrieved after excluding duplicates. Twenty-three studies were included (13 case series and 10 comparative studies). Overall level of evidence was low. Randomized and non-randomized studies had a high risk of bias. In primary palatoplasty, BFP was more frequently used filling lateral relaxing incisions(57.4%), or in the hard-soft palate junction and covering mucosal defects(30.1%). In these patients, post operative fistula incidence was 2.8%. Two studies found wider transverse maxillary dimensions after BFP use. No higher incidence of bleeding, infection, dehiscence, or flap necrosis was reported. In secondary palatoplasty, no recurrent fistulas were reported for patients undergoing BFP for fistula repair.ConclusionsBFP appears to be associated with a favorable impact in fistula prevention and management, as well as in transverse maxillary growth. However, there is a high heterogeneity among studies, high risk of bias and overall low quality of evidence. More high-quality research with long-term follow-up is warranted.

Evaluation of the Effect of Unilateral Cleft Palate on Piriform Aperture Dimensions

OBJECTIVE

The aim of the present research was to assess and compare the piriform aperture dimensions of subjects with a unilateral cleft lip and palate (UCLP) and those of a control group using cone-beam computed tomography (CBCT).

DESIGN

CBCT data of 40 subjects with a complete UCLP (28 males and 12 females, with a mean age of 17.21 ± 5.75 years) and 40 CBCT images of age- and sex-matched subjects with no cleft, serving as the control group (28 males, 12 females; mean age, 17.25 ± 5.74 years) were included in the study. The maximal height and width of the piriform aperture as well as nasal bone height were measured and statistically compared between the groups.

RESULTS

There were no significant differences in the age and sex distributions between the groups. The mean piriform aperture height was significantly lower in the UCLP group than in the control group, while the mean piriform aperture width was significantly higher in the UCLP group compared to the control group (P < .01). Furthermore, the mean bony nasal height was found to be significantly lower in the UCLP group than in the control group (P < .01).

CONCLUSIONS

According to the present findings, UCLP is associated with changes in the piriform aperture dimensions due to lower height and higher width values. These structural alterations may contribute to the functional and aesthetic nasal challenges in patients with UCLP.

Craniofacial and Velopharyngeal Dimensions in Infants 0-12 Months: Between- and Within-Group Differences Based on Age and Sex

PURPOSE

The purpose of the present study is to (a) provide quantitative data on the growth of levator veli palatini (LVP), velopharyngeal (VP), and craniofacial dimensions in children under 12 months while controlling for corrected age and sex and (b) compare variability within age and sex groups.

METHOD

Magnetic resonance imaging scans of 75 infants between 0 and 12 months were measured and divided into four age groups. These data were obtained as part of a larger retrospective study. Following exclusion criteria, scans were analyzed, and dependent variables were obtained.

RESULTS

There was a statistically significant (p < .0001) difference between corrected age groups on LVP muscle, VP, and craniofacial variables while controlling for sex. Significant growth effects were observed for LVP length (p < .0001), extravelar length (p < .0001), intravelar length (p = .048), midline thickness (p = .0001), origin-origin distance (p < .0001), velar length (p < .0001), velar thickness (p = .003), nasion-sella turcica distance (p < .0001), sella turcica-basion distance (p < .0001), and hard palate length (p < .0001). Significant sex effects were observed for pharyngeal depth (p = .026) and effective VP ratio (p = .014). When age was treated as a continuous variable, similar results were observed for all variables except pharyngeal depth. Within-group comparisons revealed the most variability occurs between 3 and 5.99 months for LVP and craniofacial variables and between 9 and 11.99 months of age for VP variables. Male participants demonstrated greater variability than female participants.

CONCLUSIONS

Differences were observed in LVP, VP, and craniofacial variables in children under 12 months while controlling for sex. Males demonstrated larger values and greater variability for most variables.

Comparison of two surgical protocols for the treatment of unilateral cleft lip and palate: a multidisciplinary systematic review and meta-analysis

There is still no unanimous agreement on the optimal surgical protocol(s) for the treatment of unilateral cleft lip and palate (UCLP), and a huge variety of protocols are employed by cleft centres across the world. The aim of this systematic review and meta-analysis was to compare reported patient outcomes of the Oslo protocol (and modifications) (OP) and delayed hard palate closure protocols (DHPCP) from a multidisciplinary perspective. A systematic search of multiple databases was conducted until September 2023. Studies reporting any patient outcomes of these protocols were included. Random-effects meta-analyses were performed for evidence synthesis, including comparisons of results between the types of protocol. The quality of evidence was evaluated using the ROBINS-I tool. In total, 62 articles (42 studies) reporting patients with UCLP were reviewed, involving 1281 patients following the OP and 655 following DHPCP. Equally poor long-term sagittal maxillofacial growth was found, and similar results for velopharyngeal insufficiency and nasolabial appearance. In contrast, OP was associated with a lower rate of oronasal fistulas. Disregarding the scarcity of comparable evidence for some domains, the results of this review, overall, favour OP over DHPCP. However, caution should be taken when interpreting the results on velopharyngeal insufficiency and oronasal fistulas, since the possibility of confounding and other biases remains.

The Effects of Radial Cartilage Incision on the Growth of Rabbit Ear

OBJECTIVES

Recently, radial cartilage incision (first-stage) at an early age combined with free auricular composite tissue grafting (second-stage) can effectively correct the concha-type microtia with the moderate or severe folded cartilage in the middle and upper third auricle, but radial cartilage incision's effects on the growth of the ear remain to be determined. The authors aimed to evaluate the effects of radial cartilage incision in young rabbits model.

METHODS

Ten New Zealand white rabbits were included in our experiment. Two ears of each rabbit were divided randomly into two groups. The experimental group was operated with radial cartilage incision, and no intervention was given to the control group. The ear width, length, and perimeter were noted every two weeks. Auricular surface area was noted at 4 and 22 weeks old. The repeated measures ANOVA was used to describe ears' growth trend. A paired-sample's t test is conducted to test whether there are significant differences among the variables through the SPSS25.0 software.

RESULTS

The growth tendencies of the ear length, width, and perimeter were observed and analyzed. The growth curves of the experimental ears were similar to that of the control. There was no significant difference in the increased ratio of surface area among the two groups. The cartilage of the experimental ears showed no change in biomechanical properties compared to that of control group.

CONCLUSION

This study shows that radial cartilage incision at an early age does not influence the growth of rabbit ear length, width, perimeter, and surface area and also does not change the biomechanical properties of the cartilage.

Stem Cell-Based Regenerative Approaches for the Treatment of Cleft Lip and Palate: A Comprehensive Review

Cleft lip and/or palate (CLP) is a prevalent congenital craniofacial abnormality that can lead to difficulties in eating, speaking, hearing, and psychological distress. The traditional approach for treating CLP involves bone graft surgery, which has limitations, post-surgical complications, and donor site morbidity. However, regenerative medicine has emerged as a promising alternative, employing a combination of stem cells, growth factors, and scaffolds to promote tissue regeneration. This review aims to provide a comprehensive overview of stem cell-based regenerative approaches in the management of CLP. A thorough search was conducted in the Medline/PubMed and Scopus databases, including cohort studies, randomized controlled trials, case series, case controls, case reports, and animal studies. The identified studies were categorized into two main groups: clinical studies involving human subjects and in vivo studies using animal models. While there are only a limited number of studies investigating the combined use of stem cells and scaffolds for CLP treatment, they have shown promising results. Various types of stem cells have been utilized in conjunction with scaffolds. Importantly, regenerative methods have been successfully applied to patients across a broad range of age groups. The collective findings derived from the reviewed studies consistently support the notion that regenerative medicine holds potential advantages over conventional bone grafting and represents a promising therapeutic option for CLP. However, future well-designed clinical trials, encompassing diverse combinations of stem cells and scaffolds, are warranted to establish the clinical efficacy of these interventions with a larger number of patients.

A systematic review of differences in outcome between one and two stage palate repair in cleft lip and palate

The aim of this systematic review was to determine whether one-stage palatoplasty for children born with cleft lip and palate shows overall advantages in outcome compared with two-stage palatoplasty. The included studies were controlled studies of syndromic and non-syndromic children born with unilateral cleft lip and palate, bilateral cleft lip and palate, or isolated cleft palate. The interventions studied were one-stage palatoplasty and two-stage palatoplasty starting with the soft palate. The outcomes were facial growth, speech, hearing, presence of fistulae, other complications related to surgery, health-related quality of life, and health economics. In total, 14 original studies were included. Results were dichotomized into showing advantage for one- or two-stage palatoplasty for the respective outcome and compared with the results from six included systematic reviews. No overall advantage for either surgical strategy was found for any of the outcome measures. The certainty of evidence was highest for the presence of fistulae, followed by facial growth and speech. For several outcomes, the quality of the existing evidence was too low to allow for any conclusions to be drawn. Neither one- nor two-stage palatoplasty showed significant advantages in clinical outcomes compared with the other. Other aspects such as ethics, economics, or surgeon's preference might hence be of more importance. Homogenous choices of outcome measures and defined minimal clinically important differences would facilitate further research.

Evidence Mapping and Quality Analysis of Systematic Reviews on Various Aspects Related to Cleft Lip and Palate

BACKGROUND

Management of cleft lip and palate is interdisciplinary. An evidence-mapping approach was envisaged to highlight the existing gaps in this field, using only the highest level of evidence.

OBJECTIVES

To conduct evidence mapping and quality analysis of systematic reviews and meta-analyses related to any aspect of cleft lip and palate.

SEARCH METHODS

The cleft lip and palate field was divided into 9 domains and 50 subdomains and a method of categorization of systematic reviews was established. A comprehensive search strategy was carried out in seven databases along with the search of gray literature and references of included articles.

SELECTION CRITERIA

Systematic reviews related to any aspect of cleft lip and palate, conducted by a minimum of two reviewers, with a comprehensive search strategy and adequate quality analysis were included.

DATA COLLECTION AND ANALYSIS

A self-designed, pre-piloted data-extraction sheet was used to collect information that was analyzed through an expert group discussion. Quality analysis was performed using ROBIS-I, AMSTAR 2, and the PRISMA checklist.

RESULTS

A total of 144 systematic reviews published between 2008 and 2022 were included. The largest number of these could be categorized in the therapeutic domain (n = 58). A total of 27% of the studies were categorized as inconclusive, 40% as partially conclusive, and 33% as conclusive. As per ROBIS-I, 77% of reviews had high risk of bias while 58% were graded as critically low in quality as per AMSTAR 2. The majority of systematic reviews showed low reporting errors.

CONCLUSIONS

The majority of systematic reviews related to cleft lip and palate relate to therapeutic and prognostic domains and show high risk of bias and critically low quality regardless of the source journal. The results of this paper might serve as a starting point encouraging authors to carry out high-quality research where evidence is lacking.

The Slavcleft: A Three-Center Study of the Outcome of Treatment of Cleft Lip and Palate Considering Palatal Shape

The degree of deviation of palatal shape from the norm may reflect facial growth disturbance in cleft lip and palate (CLP). The objective of this study was to compare the palatal morphology in children treated with different surgical protocols. Palatal shape was assessed with geometric morphometrics (GM) including Procrustes superimposition, principal component analysis (PCA), and permutation tests with 10,000 permutations, in 24 children treated with two-stage repair with a late palatoplasty (Prague group; mean age at assessment 8.9 years), 16 children after two-stage repair with early palatoplasty (Bratislava group; mean age 8.2 years), and 53 children treated with a one-stage repair (Warsaw group, mean age 10.3 years). The non-cleft control group comprised 60 children at 8.6 years. The first five principal components (PCs) accounted for a minimum of 5% of the total shape variability (65.9% in total). The Procrustes distance was largest for the Prague vs. Control pair and smallest for the Prague vs. Bratislava pair. Nonetheless, all intergroup differences were statistically significant (p < 0.01). One can conclude that variations in palatal shape roughly correspond to cephalometric and dental arch relationship findings from prior research. Among the children who underwent a one-stage repair of the complete cleft, their palatal morphology most closely resembled that of the non-cleft controls. Conversely, children who received late palatoplasty exhibited the greatest degree of deviation.

A Cross-Sectional Study of the Dental Arch Relationship and Palatal Morphology after Cleft Surgery in Italian Children with Unilateral Cleft and Lip Palate

Dental arch relationships (DARs) and palatal morphology (PM) were evaluated in in non-syndromic complete unilateral cleft lip and palate (UCLP) Italian patients after surgery. Pre- and postnatal factors affecting the results were investigated. Sixty-six children with UCLP (40 boys and 26 girls, with a mean age of 10.1 ± 2.9 years), predominantly Caucasian (77%), were consecutively enrolled in this cross-sectional study. Twenty children had received a one-stage protocol consisting of an early periosteal palate surgical repair and lip closure and forty-six were submitted to a staged surgical protocol with delayed palate repair (DPR). A single clinician collected data on their medical history and carried out a dental examination. The DAR and PM were graded on dental casts according to the Eurocran index and dichotomised as favourable and unfavourable based on the treatment outcome. Multiple logistic regression analyses demonstrated that female sex (OR = 6.08, 95% CI: 1.47-25.23, p = 0.013), DPR (OR = 4.77, 95% CI: 1.14-19.93, p = 0.032) and the use of a neonatal plate (OR = 4.68, 95% CI: 1.27-17.16, p = 0.020) increased the odds of having favourable DAR, while only DPR (OR = 9.76, 95% CI: 2.40-39.71, p = 0.001) was significantly associated with a favourable PM. Based on these findings, only DPR had a significantly favourable effect on both DAR and DM in Italian children with complete UCLP.

The Midfacial Soft Tissue Changes After Anterior Maxillary Segmental Distraction Osteogenesis in Patients With Cleft: A 3-Dimensional Volumetric-Based Subunit Analysis

BACKGROUND

Maxillary hypoplasia is common in patients with cleft lip and palate. In this study, the authors investigated the soft tissue changes in midfacial regions after anterior maxillary segmental distraction osteogenesis (AMSDO) in patients with cleft.

METHODS

Eight patients with cleft lip and palate who underwent AMSDO were enrolled in this study. Spiral computed tomographic images were taken before surgery and 6-12 months after surgery to evaluate soft tissue changes after AMSDO. The midfacial area was divided into 6 regions of interest according to anatomical subunits. The average movements of each region were calculated using volumetric changes and preoperative region surface areas.

RESULTS

The upper lip on both sides has the most anterior movement (5.22±0.86 and 5.14±0.84 mm), supracommissural regions have a little less movement (4.11±0.55 and 3.81±0.67 mm), paranasal regions have the least movement (3.37±0.47 and 3.15±0.36 mm). The corresponding regions of interest showed no significant difference on the cleft side versus the noncleft side.

CONCLUSIONS

Anterior maxillary segmental distraction osteogenesis can improve the soft tissue profile in patients with cleft, and there was no significant difference in soft tissue changes between the cleft side and the noncleft side.

The study on the morphological changes of oropharynx in patients with complete unilateral cleft lip and palate after palatopharyngeal closure

Cleft lip and palate can be treated as one of the most common craniofacial congenital malformations in humans. Such disease influences tens of millions of patients all over the world. Cleft lip and palate deformity affects many important physiological functions, including breathing, swallowing, speech, chewing, and aesthetics. This work focuses on investigating the morphology and airway volume of oropharynx patients with unilateral complete cleft lip and palate after palatopharyngeal closure. In addition, this work evaluated the similarities and differences between patients with cleft lip and palate and those without such an issue. The employed data, selected from the Department of Stomatology of Xuzhou First People's Hospital, are based on the conical beam CT images. The study sample was divided into two groups: the selected experimental group, who confronted the cleft lip, cleft palate, and velopharyngeal closure surgery, and the selected control group, who are healthy children at the corresponding age. The parameters, including the airway volume, the airway volume of velopharyngeal and oropharyngeal segments, the minimum cross-sectional area of the pharynx, the horizontal plane airway area of the hard palate and soft one, the horizontal airway area of the hyoid bone, and the vertical distance between the hard palate and soft palate, can be measured by Dolphin. These parameters were analyzed with a statistical approach. The analysis of the above-mentioned parameters reveals that the airway volume, the minimum cross-sectional area of the pharynx, the horizontal cross-sectional area of the hyoid, and the distance between the hard palate and soft palate tip in patients with complete unilateral cleft lip and palate show significant differences between the experimental group and the control group. Meanwhile, other parameters, including the horizontal cross-sectional area of the airway in the horizontal plane of the hard palate and the horizontal plane of the soft palate, did not show noticeable differences in the two groups. The patients, who confronted the unilateral complete cleft lip and palate, can improve with the velopharyngeal closure surgery. Furthermore, the length and vertical distance of the soft palate and the volume of each segment of the airway exhibit differences between the experimental group and the control group.

Primary palatoplasty: A comparison of results by various techniques - A retrospective study

Introduction:

To identify a better method for primary cleft palate (CP) repairs with respect to velopharyngeal function.

Materials and Methods:

A retrospective, longitudinal review of medical charts of patients with congenital CP who underwent four different techniques of palatoplasty, performed by three different surgeons in the Department of Maxillofacial Surgery of the National Center for Maternal and Child Health. Nasopharyngoscopy (NPS) was used for velopharyngeal function evaluation. CP was classified according to the Veau system and the “Golding-Kushner” scale for NPS results was used for assessing the patient’s velopharyngeal function and its association with cleft types and the primary palatoplasty techniques. Pearson’s Chi-square analysis and binary logistic regression were used for statistical analysis.

Results:

A total of 335 patients were included in the study. The mean age at primary palate repair was 22.9 ± 13.6 months. There were 56, 42, 177, and 60 patients with Veau-I, Veau-II, Veau-III, and Veau-IV types, respectively, whereas for primary palatoplasty 65 patients underwent Furlow, 148 patients – Mongolian, 108 patients – two flap, 34 patients – von Langenbeck technique. NPS assessment of adequate velopharyngeal function was followed by Furlow’s technique in 89.4% of cases, Mongolian technique in 62.2% of cases but by “two flap” only in 48.1% and von Langenbeck in 47.1% of cases.

Discussion:

The Furlow and Mongolian techniques were superior for maintaining velopharyngeal function after primary palatoplasty.

Orthognathic Surgery Rate in Cleft Care

PURPOSE

To determine the true need for orthognathic surgery in patients with repaired cleft lip and/or palate (CL/P) at a high-volume craniofacial center.

METHODS

An institutional retrospective review of patients with CL/P born between 1975 and 2008 was performed. Patients with adequate documentation reflecting cleft care who were ≥ 18 years at the time of last craniofacial/dentistry follow-up were included. Patients with non-paramedian clefts or a comorbid craniofacial syndrome were excluded. Primary outcome variable was the total proportion of patients with CL/P who either underwent or were referred for orthognathic surgery Le Fort I (LF1) to correct midface hypoplasia. Secondary outcome variables were associations between cleft phenotype, midface hypoplasia severity, and number of cleft related surgeries with the eventual LF1 referral/recipiency.

RESULTS

One hundred seventy-seven patients with CL/P met inclusion criteria. A total of 90/177 (51%) patients underwent corrective LF1; however, 110/177 (62%) of patients were referred for surgery. Patients with secondary cleft palate involvement were referred for and underwent LF1 at significantly greater rates than those without secondary palate involvement (referred: 65% versus 13%, P = 0.001; underwent: 55% versus 0%, P < 0.001). Patients with bilateral cleft lip/palate were referred for and underwent LF1 at significantly higher rates than those with unilateral cleft lip/palate (referred: 71.0% versus 50.4%, P= 0.04; underwent: 84% versus 71%, P = 0.02). Number of secondary palate surgeries was positively correlated with increased LF1 referral (P = 0.02) but not LF1 recipiency (P = 0.15).

CONCLUSIONS

The incidence of orthognathic surgery redundant in patients with repaired CL/P was 51% at our institution, marginally above the higher end of previously reported rates. However, this number is an underrepresentation of the true requirement for LF1 as 62% of patients were referred for surgical intervention of midface hypoplasia. This distinction should be considered when counseling families.

Correlation between surgical protocols for palatoplasty and midfacial growth in cleft lip and palate patients: A long-term, single centre study

To evaluate and compare the outcomes of two different surgical protocols for palatoplasty for midfacial growth in patients with cleft lip and palate. A retrospective observational cohort study was conducted in 80 patients with cleft lip and palate, who were divided into two groups. Group 1 comprised patients who underwent operation between 9 and 11 months of age using the Bardach two-flap technique without a palatal pushback. Group 2 comprised patients who had undergone operation between 18 and 20 months of age using either a Bardach two-flap technique with a palatal pushback or a von Langenbeck technique. Patient follow-up was done between 8 and 9 years of age when they reported to the centre for secondary alveolar bone grafting. Post-surgical cephalometric measurements were taken for midfacial growth analysis. Group 1 underwent palatoplasty at significantly younger ages than Group 2 (p < 0.01). A statistically significant difference(p < 0.01) was found between the two groups of patients on comparison of cephalometric parameters such as SNA, ANB, CoA, NperpA ANS-PNS, N-ANS, N-Me, Witt's (AO-BO). Group 2 had more positive cephalometric values as compared to Group 1, thereby implying that there was less incidence of midfacial hypoplasia in patients treated at the age of 18-20 months. Between the types of palatoplasty techniques within Group 2, i.e., Bardach two-flap and von Langenbeck, there was no statistical difference found in the post-opertative cephalometric values, i.e., SNA, ANB, CoA, ANS-PNS, N-ANS, N-Me, Witt's (AO-BO) except for Nperp-A, which showed a statistical difference (p = 0.03). Within the limitations of the study which is only a single center experience it seems that palatal closure should be carried out at 18-20 months of age for better midfacial growth, leading to decreased incidence of maxillary hypoplasia at a later stage in life. Repair at less than 18 months of age is also associated with mid-facial hypoplasia.

The Relationship Between Maxillary Growth and Speech in Children With a Unilateral Cleft Lip and Palate at 5 Years of Age

OBJECTIVE

This study sought to investigate the association between maxillary growth and speech outcomes for children with a repaired unilateral cleft lip and palate (UCLP) at 5 years of age.

PARTICIPANTS

In all, 521 children (180 females and 341 males) with a nonsyndromic complete UCLP, born between 2007 and 2012 in England, Wales, and Northern Ireland were included in this study.

OUTCOME MEASURES

Maxillary growth was analyzed using dental models scored by the 5-Year-Olds' index, and perceptual speech analyses were scored by the Cleft Audit Protocol for Speech - Augmented rating.

RESULTS

Forty-one percent of the children achieved good maxillary growth (scores 1 and 2 on 5-Year-Old' index). Fifty percent of the children achieved normal speech (achieving UK speech standard 1). Maxillary growth was not found to have an impact on speech outcome when described by the 3 UK National Cleft Lip and Palate Speech Audit Outcome Standards. Analysis according to individual speech parameters showed dentalizations to be less prevalent in children with good maxillary growth compared to fair and poor growth (P = .001). The remaining speech parameters within resonance, nasal airflow, and articulation categories were not significantly associated with maxillary growth.

CONCLUSION

The findings from this study suggest that children with a history of complete UCLP, who have poor maxillary growth, are not at a higher risk of having major speech errors compared to children with good or fair maxillary growth at 5 years of age.

Superior Orbicularis Oris Muscle Activity in Children Surgically Treated for Bilateral Complete Cleft Lip and Palate

The aim of this cross-sectional study was to evaluate the electromyographic activity of the superior orbicularis oris muscle both in children surgically treated for bilateral complete cleft lip and palate (BCCLP) as well as in subjects without BCCLP. The study comprised 77 children aged 6.6 to 12.5 years. All the patients with clefts had previously undergone lip and palate surgery. The upper lip electromyographic (EMG) assessments were made with a DAB-Bluetooth device (Zebris Medical GmbH, Germany) at rest, while swallowing saliva, protruding lips and compressing lips. EMG measurements were also made when the subjects produced phonemes /p/, /b/, and /m/ with the vowel /a/. The Mann-Whitney U test was applied to statistically analyze the EMG values. Significantly higher median upper lip EMG activity under working conditions such as swallowing saliva, lip compression, and production of the phoneme /p/ with the vowel /a/ was observed in patients with BCCLP compared to those without a cleft. The results of the study showed that the upper lip muscle activity increases in children with BCCLP when swallowing saliva, compressing lips and during some speech movement tasks. This may be important in the aspect of the effect of surgical lip repair on the craniofacial growth.

[Ultrasound scan of a fetus with facial cleft must be done from the lip to the uvula: What's new?]

Facial cleft are the most frequent craniofacial anomalies with an incidence of one for 1000 births, all births combined, and require specialized multidisciplinary care. Since 2005, the systematic realization of two ultrasound views (nose-lip and profile) is recommended for the exploration of the fetal face in the 2nd trimester of pregnancy. Application of these recommendations should allow screening of the majority of cleft lip and palate. However, cleft palates, without labiomaxillary involvement, are currently largely underdiagnosed at prenatal ultrasound, although they can be associated with a syndromic diagnosis in up to 30% of cases. The aim of this work is to describe, from embryology to surgical consultation, the complete ultrasound examination of a fetus with a classic facial cleft.
