Congenital orofacial cleft, the most common birth defect in the maxillofacial region, exhibits a wide range of prognosis depending on the severity of deformity and underlying etiology. Non-syndromic congenital orofacial clefts typically present with milder deformities and more favorable treatment outcomes, whereas syndromic congenital orofacial clefts often manifest with concomitant organ abnormalities, which pose greater challenges for treatment and result in poorer prognosis. This consensus provides an elaborate classification system for varying degrees of orofacial clefts along with corresponding diagnostic and therapeutic guidelines. Results serve as a crucial resource for families to navigate prenatal screening results or make informed decisions regarding treatment options while also contributing significantly to preventing serious birth defects within the development of population.

Muenke syndrome is an autosomal dominant genetic disorder that is typically characterized by unilateral or bilateral coronal synostosis, macrocephaly, midface hypoplasia, and developmental delays. This article reports a case of Muenke syndrome with a soft cleft palate. A heterozygous missense mutation c.749C>G (p.P250A) was identified in the FGFR3 gene through genetic testing. The patient exhibited typical features including coronal synostosis, bilateral hearing loss, right accessory auricle, and developmental delays and underwent surgery to repair the soft cleft palate. Cases of Muenke syndrome with cleft palate in the literature are relatively rare, and common associated symptoms include coronal suture craniosynostosis and hearing impairment. This article reports a differential diagnosis with other craniosynostosis syndromes and provides a reference for clinical diagnosis and treatment.

The prevention, prenatal diagnosis and postnatal treatment of cleft lip and palate form a comprehensive treatment process requiring multidisciplinary participation. Prevention and treatment of cleft lip and palate involve multiple disciplines. The timing of professional intervention often cross and overlap, intervention and the sequence of treatment had a great influence on the outcome of the treatment. In the meantime, under the premise of the change of national fertility policy, the reproductive needs of families with cleft lip and palate, such as fertility intervention and diagnosis etc., should be paid attention to through the whole chain of pre-pregnant, prenatal and post-natal interventions. Therefore, this paper proposes a multidisciplinary treatment process for the comprehensive diagnosis and treatment of cleft lip and palate. It primarily combs and standardizes the discipline composition, data preparation, consultation contents, personnel, time and technical points of the consultation records of the multidisciplinary treatment in antenatal, postnatal, infant, adolescent, adult and reproductive stages of cleft lip and palate.

OBJECTIVE: To explore the genetic basis for a fetus with cleft lip and palate. METHODS: Copy number variations (CNVs) in the fetus and his parents were detected with chromosomal microarray analysis (CMA). RESULTS: As revealed by the CMA assay, the fetus has carried a 228 kb deletion in Xp11.22 region and a 721 kb duplication in 9p21.1. Both CNVs were inherited from the parents. The CNV in Xp11.22 was predicted to be pathogenic by involving the PHF8 gene, whilst the CNV in 9p21.1 was predicted to be benign. CONCLUSION Deletion of the Xp11.22 region probably underlies the cleft lip and palate in this fetus.

Craniofacial abnormalities are common. It is important to examine the fetal face and skull Epub ahead of print during prenatal ultrasound examinations because abnormalities of these structures may indicate the presence of other, more subtle anomalies, syndromes, chromosomal abnormalities, or even rarer conditions, such as infections or metabolic disorders. The prenatal diagnosis of craniofacial abnormalities remains difficult, especially in the first trimester. A systematic approach to the fetal skull and face can increase the detection rate. When an abnormality is found, it is important to perform a detailed scan to determine its severity and search for additional abnormalities. The use of 3-/4-dimensional ultrasound may be useful in the assessment of cleft palate and craniosynostosis. Fetal magnetic resonance imaging can facilitate the evaluation of the palate, micrognathia, cranial sutures, brain, and other fetal structures. Invasive prenatal diagnostic techniques are indicated to exclude chromosomal abnormalities. Molecular analysis for some syndromes is feasible if the family history is suggestive.

OBJECTIVETo carry out genetic analysis for a fetus with Dandy-Walker malformation and provide prenatal diagnosis for its parents during the subsequent pregnancy.

METHODSRoutine G-banding was carried out to analyze the karyotype of the fetus and its parents, and next-generation sequencing (NGS) and fluorescence in situ hybridization (FISH) were used to verify the result.

RESULTSThe father showed a normal karyotype, while the mother was found to carry a balanced t(11; 22) (q23; q11) translocation. NGS and FISH analysis verified that the supernumerary marker chromosome carried by the fetus was der(22) t(11; 22) (q23;q11). The fetus was diagnosed with Emanuel syndrome. During the next pregnancy, the fetus was found to carry the same balanced translocation as its mother. After genetic counseling, the couple decided to continue with the pregnancy, and eventually delivered a healthy baby.

CONCLUSIONA fetal case of Emanuel syndrome has been identified. The derivative der(22) t(11; 22)(q23; q11) chromosome probably underlies the Dandy-Walker malformation in the fetus. Combined cytogenetic and molecular analyses can attain a more precise diagnosis for fetal abnormalities detected by ultrasonography.

Neonatal hypocalcemia and congenital heart defects has been known as the first clinical manifestation of the chromosome 22q11.2 deletion syndrome (22q11DS). However, because of its wide clinical spectrum, diagnosis of 22q11DS can be delayed in children without classic symptoms. We report the case of a girl with the history of imperforate anus but without neonatal hypocalcemia or major cardiac anomaly, who was diagnosed for 22q11DS at the age of 11 after the onset of overt hypocalcemia. She was born uneventfully from phenotypically normal Korean parents. Imperforate anus and partial cleft palate were found at birth, which were surgically repaired thereafter. There was no history of neonatal hypocalcemia, and karyotyping by GTG banding was normal. At the age of 11, hypocalcemia (serum calcium, 5.0 mg/dL) and decreased parathyroid hormone level (10.8 pg/mL) was noted when she visited our Emergency Department for fever and vomiting. The 22q11DS was suspected because of her mild mental retardation and velopharyngeal insufficiency, and a microdeletion on chromosome 22q11.2 was confirmed by fluorescence in situ hybridization. The 22q11DS should be considered in the differential diagnosis of hypocalcemia at any age because of its wide clinical spectrum.

BACKGROUND: Nasalance is used to evaluate the velopharyngeal incompetence in clinical diagnoses using a nasometer. The aim of this study is to find the nasalance differences between Vietnamese cleft palate children and Korean cleft palate children by measuring the nasalance of five oral vowels. METHODS: Ten Vietnamese cleft palate children after surgery, three Vietnamese children for the control group, and ten Korean cleft palate children after surgery with the same age participated in this experimentation. Instead of Korean control, the standard value of Korean version of the simplified nasometric assessment procedures (kSNAP) was used. RESULT: The results are as follows: (1) the highest nasalance score among the Vietnamese normal vowels is the low vowel /a/; however, that of Korean normal vowels is the high vowel /i/. (2) The average nasalance score of Korean cleft palate vowels is 18% higher than that of Vietnamese cleft palate vowels. There was a nasalance score of over 45% among the vowels /e/ and /i/ in Vietnamese cleft palate patients and /i/, /o/, and /u/ in Korean cleft palate patients. CONCLUSION: These different nasalance scores of the same vowels seem to cause an ethnic difference between Vietnamese and Korean cleft palate children.

PURPOSE: The purpose of this study was to evaluate the feasibility and usefulness of sagittal color Doppler ultrasonography (CDUS) for the diagnosis of fetal cleft lip (CL) and cleft palate (CP). METHODS: We performed targeted ultrasonography on 25 fetuses with CL and CP, taking coronal and axial images of the upper lip and maxillary alveolar arch in each case. The existence of defects in and malalignment of the alveolus on the axial image, hard palate defects on the midsagittal image, and flow-through defects on CDUS taken during fetal breathing or swallowing were assessed. We compared the ultrasonography findings with postnatal findings in all fetuses. RESULTS: Alveolar defects were detected in 16 out of 17 cases with CP and four out of eight cases with CL. Alveolar malalignment and hard palate defects were detected in 11 out of 17 cases and 14 out of 17 cases with CP, respectively, but not detected in any cases with CL. Communicating flow through the palate defect was detected in 11 out of 17 cases of CL with CP. The accuracy of detection in axial scans of an alveolar defect and malalignment was 80% and 76%, respectively. Accuracy of detection of in mid-sagittal images of hard palate defect and flow was 80% and 86%, respectively. The overall diagnostic accuracy of combined axial and sagittal images with sagittal CDUS was 92%. CONCLUSION: Sagittal CDUS of the fetal hard palate is a feasible method to directly reveal hard palate bony defects and flow through defects, which may have additional value in the differential diagnosis of fetal CL and CP.

BACKGROUND: The prenatal ultrasound detection of cleft lip with or without cleft palate (CL/P) and its continuous management in the prenatal, perinatal, and postnatal periods using a multidisciplinary team approach can be beneficial for parents and their infants. In this report, we share our experiences with the prenatal detection of CL/P and the multidisciplinary management of this malformation in our institution's Congenital Disease Center. METHODS: The multidisciplinary team of the Congenital Disease Center for mothers of children with CL/P is composed of obstetricians, plastic and reconstructive surgeons, pediatricians, and psychiatrists. A total of 11 fetuses were diagnosed with CL/P from March 2009 to December 2013, and their mothers were referred to the Congenital Disease Center of our hospital. When CL/P is suspected in the prenatal ultrasound screening examination, the pregnant woman is referred to our center for further evaluation. RESULTS: The abortion rate was 28% (3/11). The concordance rate of the sonographic and final diagnoses was 100%. Ten women (91%) reported that they were satisfied with the multidisciplinary management in our center. CONCLUSIONS: Although a child with a birth defect is unlikely to be received well, the women whose fetuses were diagnosed with CL/P on prenatal ultrasound screening and who underwent multidisciplinary team management were more likely to decide to continue their pregnancy.
