AI Article Synopsis
- The study aimed to find how common aneuploidy and major anatomical abnormalities are in fetuses and neonates with cleft lip and/or palate in Utah between 1995-1999.
- Of the 263 cases reviewed, 5.7% were aneuploid, with higher rates in those with bilateral cleft lip and palate compared to unilateral cases.
- Additional significant anatomical abnormalities were found in around 7% to 21% of cases, particularly affecting the heart and central nervous system, highlighting the need for amniocentesis and thorough counseling for affected patients.
Article Abstract
Objective: To determine the prevalence of aneuploidy and additional major anatomic abnormalities in fetuses and neonates with cleft lip with or without cleft palate.
Methods: All cases of cleft lip with or without cleft palate (cleft lip/cleft palate) occurring in Utah from 1995 through 1999 were reviewed by using the Utah Birth Defect Network population-based surveillance system. All pregnancy outcomes are included (stillborn, live born, and termination) in this analysis.
Results: Of 263 cases of cleft lip/cleft palate, 72 (27.4%) were unilateral cleft lip, 112 (42.6%) were unilateral cleft lip and cleft palate, 12 (4.6%) were bilateral cleft lip, and 67 (25.5%) were bilateral cleft lip and cleft palate. Fifteen (5.7%) of the 263 fetuses and neonates were aneuploid. One (1.2%) with cleft lip (unilateral and bilateral combined) was aneuploid. Five (4.5%) of the fetuses and neonates with unilateral cleft lip and cleft palate were aneuploid compared with 9 (13.4%) of fetuses and neonates with bilateral cleft lip and cleft palate. In known or presumed euploid fetuses and neonates, additional sonographically occult major anatomic abnormalities occurred in 5 (7.0%) of 71 with unilateral cleft lip, 18 (16.8%) of 107 with unilateral cleft lip and cleft palate, 1 (8.3%) of 12 with bilateral cleft lip, and 12 (20.7%) of 58 with bilateral cleft lip and cleft palate. These abnormalities primarily involved the heart and the central nervous system.
Conclusions: Amniocentesis for karyotype should be offered in all cases of cleft lip/cleft palate because of the risk of aneuploidy. Patients should be counseled that sonographically occult additional anatomic abnormalities might be present with all clefts.

Background: Cleft lip and palate is the most frequent malformation in humans that requires surgical correction but is not primarily life-threatening. That is why in many economically not very well developed countries, special surgical care, such as for cleft lip and palate, is not guaranteed at all or is not sufficiently guaranteed, so that numerous aid organizations have been founded for over 50 years to provide help by organizing surgical aid missions. Even if this help seems primarily ethically harmless and very laudable, the lack of rules and instructions unfortunately regularly leads to the fact that legal, ethical and even medical treatment standards are often not observed to the detriment of the affected children.

Introduction: The objective of this study was to evaluate the effects of the miniplate application sites in the maxilla and the applied force vector changes during skeletally supported facemask application in adolescent patients with unilateral cleft lip and palate (UCLP) using finite element model (FEM) analysis.
Methods: A FEM was obtained from a cone-beam computed tomography image of a 12-year-old female patient with UCLP. Miniplates were placed on 3 different sites of the maxilla; 500 g of advancement force was applied bilaterally, parallel (0°), and downward (-30°) to the occlusal plane.
