Background: Cleft lip and palate (CLP) can affect the development of the maxilla; which may create a midfacial deficiency as well as an interference of the facial growth pattern and dentofacial esthetics.
Objective: This study aimed to estimate the chronological age of complete fusion of the spheno-occipital synchondrosis (SOS) in cleft lip and palate patients and a control group; using cone beam computed tomography (CBCT) images.
Methods: In this retrospective study; 125 patients were enrolled (cleft lip and palate group ( = 91); control group ( = 34)). Age comparison was made with a chi-square test; and a Kaplan-Meier analysis determined the median time to reach complete fusion of the spheno-occipital synchondrosis ( <0.05).
Results: The experimental group showed statistically significant differences in the median time for complete ossification between males and females ( = 0.019). The median time for complete ossification of the spheno-occipital synchondrosis was; for males; 15.0 years in both groups; for females; it was 14.0 years and 13.0 years in the experimental group and in the control group; respectively. Both for males and females; there were no statistically significant differences between experimental and control groups ( = 0.104).
Conclusions: The present study showed no differences in the ossification of the spheno-occipital synchondrosis between individuals with and without cleft lip and/or palate.

Ankyloblepharon-Ectodermal Defects-Cleft Lip/Palate (AEC) syndrome is a rare genetic disorder caused by mutations in the TP63 gene, which encodes a transcription factor essential for epidermal gene expression. A key feature of AEC syndrome is chronic skin erosion, for which no effective treatment currently exists. Our previous studies demonstrated that mutations associated with AEC syndrome lead to p63 protein misfolding and aggregation, exerting a dominant-negative effect.

: Defects in maxillary and mandibular continuity are common in maxillofacial practice. They can occur after trauma, osteonecrosis, congenital jaw deformities, or surgical resection of benign or malignant tumours. Reconstruction with microvascular bone flaps and subsequent prosthetic rehabilitation is considered the contemporary first line treatment.

This study describes the results of whole exome sequencing in the etiological investigation and genetic counseling of families presenting with non-syndromic oral clefts with vertical transmission recorded in the Brazilian Database on Craniofacial Anomalies. Whole exome sequencing was performed in 18 families presenting with non-syndromic oral clefts with vertical transmission, and variant filtering was used to identify rare, and also possibly pathogenic variants in genes associated with oral clefts. Overall, our study identified seven families (38.

As individuals with a cleft lip and palate (CLP) transition into adulthood, they face unique employment challenges related to income, job stability, and fewer career options. This study explored these challenges through two focus group discussions with 19 participants (aged 21-38), primarily women, to understand their employment experiences. Thematic analysis revealed the following three main themes: (1) physical factors, (2) psychosocial factors, and (3) overcoming employment challenges, with nine sub-themes including speech, hearing, appearance, health, childhood experiences, societal expectations, lack of self-confidence, communication improvement, and self-esteem building.
