Journal of Ultrasound in Medicine :... Mar 2024To prospectively evaluate the prognosis of fetuses diagnosed with micrognathia using prenatal ultrasound screening.
OBJECTIVE
To prospectively evaluate the prognosis of fetuses diagnosed with micrognathia using prenatal ultrasound screening.
METHODS
Between January 2019 and December 2022, a normal range of IFA to evaluate the facial profile in fetuses with micrognathia in a Chinese population between 11 and 20 gestational weeks was established, and the pregnancy outcomes of fetal micrognathia were described. The medical records of these pregnancies were collected, including family history, maternal demographics, sonographic findings, genetic testing results, and pregnancy outcomes.
RESULTS
Ultrasound identified 25 patients with fetal micrognathia, with a mean IFA value of 43.6°. All cases of isolated fetal micrognathia in the initial scans were non-isolated in the following scans. A total of 78.9% (15/19) cases had a genetic cause confirmed, including 12 with chromosomal abnormalities and 3 with monogenic disorders. Monogenic disorders were all known causes of micrognathia, including two cases of campomelic dysplasia affected by SOX9 mutations and one case of mandibulofacial dysostosis with an EFTUD2 mutation. In the end, 19 cases were terminated, 1 live birth was diagnosed as Pierre Robin syndrome, and 5 cases were lost to follow-up.
CONCLUSION
IFA is a useful indicator and three-dimensional ultrasound is a significant support technique for fetal micrognathia prenatal diagnosis. Repeat ultrasound monitoring and genetic testing are crucial, with CMA recommended and Whole exome sequencing performed when normal arrays are reported. Isolated fetal micrognathia may be an early manifestation of monogenic disorders.

Stickler syndrome (SS) is a congenital autosomal dominant condition that affects the formation of collagen. Of primary importance to the anesthesia provider is the propensity for difficulties in managing the airway due to orofacial abnormalities associated with this syndrome. The authors present a two-year-old infant with SS who required anesthetic care for a cleft palate repair. The potential anesthetic implications of this syndrome are discussed and the importance of proper planning and preparation and the usefulness of ultrasound as an airway evaluation tool are highlighted.

OBJECTIVES
This is the first national study to investigate the incidence of non-syndromic oro-facial clefts (NSOFC) and Pierre-Robin-Sequence in Saudi Arabia over the Covid-19 pandemic period.
METHODS
All maternity hospitals (30-hospitals) in the major regions and cities of Saudi from November 2020-to-2021 were included in the study. Patients were evaluated for cleft phenotype using the LASHAL-classification system. The incidence of NSOFC in Saudi Arabia was calculated by comparing the number of NSOFCs cases born out of all live births during the study period at the included hospitals. Clinical examination was performed and information was gathered using a validated data collection form.
RESULTS
In one year, 140,380 live-infants were born at the selected hospitals. Of these, 177 were diagnosed with NSOFC giving an incidence of 1.26/1,000 live-births in Saudi Arabia and the highest incidence in Medina city (2.46/1000 live-births). The incidence of cleft lip-and-palate (0.67/1000 live-births) was higher than that of cleft-palate (0.37/1000 live-births) and cleft-lip (0.22/1000 live-births). Pierre-Robin Sequence incidence was (0.04/1000 live-births). There were 21(12.1) or 23(13.2%) of NSOFC's mothers exposed or vaccinated with Covid-19, respectively.
CONCLUSION
The national incidence of NSOFC in Saudi Arabia was 1.26/1000 live births with variation between phenotypes and regions in the country. In addition, to reporting Covid-19 infection prevalence and vaccine exposure among NSOFC's mothers, this study represents the first of its type to evaluate NSOFC prevalence in Saudi Arabia on a national level.

Klippel-Feil syndrome-4 (KFS4), a rare autosomal recessive form of Klippel- Feil syndrome, is characterized by facial dysmorphism, nemaline myopathy, and short stature. Only 10 cases of KFS4 have been previously published in the literature. We report a novel case of a 1- month-old girl with known KFS4 and Robin Sequence (RS). At 2 months old, she underwent bilateral mandibular distraction osteogenesis to correct significant airway obstruction. Despite adequate mandibular advancement, the patient failed extubation twice and eventually required a tracheostomy. Due to the multiple anomalies present in KFS4, mandibular distraction osteogenesis may have a decreased likelihood of surgical success.

Brainstem evoked response audiometry (BERA) is the most established and recommended objective audiometric method for the clinical diagnosis of hearing impairment in high-risk infants. It is unclear whether infants with orofacial clefts meet the criteria for the high-risk group. This retrospective cohort study evaluated the need for diagnostic BERA in infants with cleft palate with or without cleft lip by assessing the predisposition to and diagnosis of congenital hearing impairment. Data from 122 patients treated at a single cleft centre were evaluated. BERA was conducted at the time of palate repair at 4-6 months of age. Clinical follow-up was analysed up to 4 years. The presence of a syndrome was examined as a risk factor for congenital hearing impairment. Among the 122 patients, four had congenital sensorineural or mixed hearing loss requiring hearing aids. All affected patients had syndromes in addition to the cleft. Most patients with elevated hearing thresholds had transient conductive hearing loss. Most suspected sensorineural hearing loss initially diagnosed was refuted. However, a higher incidence of sensorineural hearing loss was found in patients with syndromic clefts, supporting the diagnostic use of BERA with initial surgery only in patients with syndromic clefts.

Meta-Analysis Review
Robin sequence (RS), a congenital disorder of jaw maldevelopment and glossoptosis, poses a substantial healthcare burden and has long-term health implications if airway obstruction is suboptimally treated. This study describes the global birth prevalence of RS and investigates whether prevalence estimates differ by geographical location, ethnicity or study data source (registry non-registry data). The protocol was prospectively registered with PROSPERO.Databases were searched using keywords and subject terms for "Robin sequence", "epidemiology", "incidence" and "birth prevalence". Meta-analysis was performed fitting random effects models with arcsine transformation.From 34 eligible studies (n=2722 RS cases), pooled birth prevalence was 9.5 per 100 000 live births (95% CI 7.1-12.1) with statistical heterogeneity. One third of studies provided a case definition for RS and numerous definitions were used. A total of 22 countries were represented, predominantly from European populations (53% of studies). There was a trend towards higher birth prevalence in European populations and lower prevalence from registry-based studies. Only two studies reported ethnicity.This study indicates that RS occurs globally. To investigate geographical differences in prevalence, additional studies from non-European populations and reporting of ethnicity are needed. Heterogeneity of estimates may be due to variable diagnostic criteria and ascertainment methods. Recently published consensus diagnostic criteria may reduce heterogeneity among future studies.

BACKGROUND
Cleft lip and/or palate (CL/P) can be accompanied by other congenital anomalies. We conducted a long-term evaluation of the associations between cleft patterns, sex distribution, and accompanying congenital anomalies of patients with CL/P.
METHODS
The medical records of 739 patients with CL/P, seen between January 1967 and December 2020, were retrospectively reviewed. Fisher's exact test was used for statistical analysis.
RESULTS
Among the 739 patients with CL/P, the male-to-female ratio was 1.1. Regarding the cleft pattern, 121 (16.4%), 104 (14.1%), 280 (37.9%), 198 (26.8%), and 36 (4.9%) patients had cleft lip (CL), cleft lip and alveolus (CLA), cleft lip and palate (CLP), cleft palate (CP), and submucous cleft palate (SMCP), respectively. Congenital anomalies were identified in 107 (14.5%) cases, of which 53 (49.5%) had congenital heart disease. The frequencies of congenital anomalies patients with in CL/P were 14/225 (6.2%), 36/280 (12.9%), 43/198 (21.7%), and 14/36 (38.9%) for a combination of CL and CLA, CLP, CP, and SMCP, respectively. Accompanying syndromes and chromosomal anomalies were identified in 40 (5.4%) cases, in which Pierre Robin sequence (16 cases of CP and 4 cases of SMCP) was the most frequent.
CONCLUSION
No sex differences were observed in CL/P, and CLP and CP were the most common cleft patterns. Congenital anomalies associated with CL/P were dominated by congenital heart disease and were most frequently identified in CP and SMCP cases. Notably, the Pierre Robin sequence, a complex syndrome characterized by micrognathia, glossoptosis, respiratory obstruction, and a U- or V-shaped CP, was found in cases of both CP and SMCP, and accounted for the symptoms in most cases.

The purpose of this study was to provide the experience of a single center with mandibular distraction osteogenesis (MDO) in Pierre Robin Sequence (PRS) patients. A longitudinal research analysis was conducted to identify PRS patients who underwent MDO at Vietnam National Children's Hospital between 2019 and 2021. The following criteria were used to determine inclusion: 1) those pediatric patients with PRS who were not well handled with conservative therapy, 2) those who received MDO with internal mandibular distractors, and 3) no previous treatment elsewhere. Demographic data, postoperative complications, and surgical results were all evaluated. The inclusion criteria were met by 73 patients. There were no difficulties associated with our distraction strategy. The majority of individuals with tracheostomies were successfully decannulated, and the remainder were able to avoid tracheostomies. Using MDO in PRS is an effective technique to avoid future airway issues. The success rate was lower and the complication rate higher for patients who had a tracheotomy before distraction and for those who underwent distraction at an age older than 2 months. The presence of laryngomalacia, gastric reflux disease, cardiac abnormalities, and GI anomalies did not increase the likelihood of MDO failure in PRS patients.

BACKGROUND
The obstruction of the upper airway (UAO) in infants diagnosed with Robin Sequence (RS) is caused by micrognathia, and in severe cases, it can result in obstructive sleep apnea (OSA). Mandibular distraction osteogenesis (MDO) is a secure and efficient remedy for significant UAO. However, there is insufficient data on the related cephalometric changes. Therefore, this study meticulously analyzes the mandibular cephalometric changes in infants with RS who have undergone MDO using internal devices. The aim is to gain a more comprehensive understanding of the short- and long-term impacts of distraction on the mandible.
METHODS
The study examined 73 consecutive cases of mandibular distraction osteogenesis (MDO) performed by a single surgeon. Preoperative and postoperative lateral cephalograms, as well as CT scans of the mandible, were utilized to assess population averages for both time points. A two-sample T-Test with equal variance was used for this analysis.
RESULTS
After the MDO procedure, 19 out of 21 cephalometric parameters exhibited significant morphological changes. On average, there were notable improvements of 20.3 mm (60.7%) in length, 9.8 mm (49.7%) in height, 12.6 mm (36.1%) in width, and 211% in airway parameters. However, most parameters showed only mild regression at the time of device removal and 6 to 12 months post-MDO. Nonetheless, the cephalometric parameters remained significantly improved compared to the preoperative measurements.
CONCLUSIONS
The use of cephalometric measurement is a potent approach that provides a clear and measurable understanding of how MDO influences both immediate and long-term growth of the mandible. This quantitative assessment of the effects of mandibular distraction allows for the refinement of surgical techniques and the optimization of outcomes. Therefore, incorporating cephalometric measurements in the evaluation of patients undergoing MDO can lead to better surgical planning and more favorable results.
