INTRODUCTION: Craniosynostosis, the premature fusion of cranial sutures, is usually divided into 2 major categories: syndromic and nonsyndromic. Mutations in the FGFR1, FGFR2, FGFR3, TWIST1, and EFNB1 genes cause the common craniosynostosis syndromes Muenke, Crouzon and Crouzon with acanthosis nigricans, Apert, Pfeiffer, Saethre-Chotzen, and Craniofrontonasal. Overlapping features among craniosynostosis syndromes, phenotypic heterogeneity even within the same syndrome, especially in the case of Muenke syndrome, and inadequate clinical evaluation can lead to misdiagnosis, which molecular testing can help clarify...

BACKGROUND: The polymalformative syndromes and craniofacial anomalies association is a well-known phenomenon in patients with Crouzon's, Pfeiffer, Apert or Muenke disease. Recently, other less frequent pathologies, such as Alagille syndrome, are showing an association with alterations in the development of cranial sutures resulting in serious cosmetic defects and neurological disorders. CASE DESCRIPTION: The authors report an exceptional case of a 30-month-old girl, nephroblastoma survivor, diagnosed with Alagille syndrome who is referred to our department with progressive anterior plagiocephaly and premature left coronal suture closure associated with a large compensating right bossing...

Crouzon syndrome (CS) is one of the craniosynostosis syndromes that leads to early fusion of cranial sutures and increased intracranial pressure. Intracranial hypertension is a serious complication that may lead to vision loss and cognitive impairment. Early detection and management are necessary to prevent complications. The authors present a patient with CS who underwent posterior cranial vault reconstruction with internal distraction after multiple episodes of headache and papilledema. The patient was unaware of any loss of color vision before the surgery; however, he noted an improvement in his color vision after the surgery...

Patients with considerable maxillomandibular anteroposterior discrepancies and maxillary hypoplasia require corrective treatment through orthognathic surgery. However, in the treatment of severe maxillary retrognathism, it is necessary to reconstruct areas of bone deficiency through grafting techniques in addition to maxillary advancement using only the Le Fort I osteotomy. Treatment in these patients is more challenging and requires high surgical predictability. Alloplastic materials often have been used for the reconstruction of poor bone contours...

Craniosynostosis (occurrence: 1/2500 live births) is a result of premature fusion of cranial sutures, leading to alterations of the pattern of cranial growth, resulting in abnormal shape of the head and dysmorphic facial features. In approximately 85% of cases, the disease is isolated and nonsyndromic and mainly involves only one suture. Syndromic craniosynostoses such as Crouzon, Apert, Pfeiffer, Muenke, and Saethre-Chotzen syndromes not only affect multiple sutures, but are also associated with the presence of additional clinical symptoms, including hand and feet malformations, skeletal and cardiac defects, developmental delay, and others...

Crouzon syndrome with acanthosis nigricans (CAN) is caused by a mutation in the fibroblast growth factor receptor ( FGFR) 3 gene that presents clinically as Crouzonoid craniofacial features in association with other anomalies such as acanthosis nigricans and benign odontogenic tumors. Diagnosis through the use of genetic mutational analysis is critical, as it alerts the surgeon to the need for careful screening for jaw tumors so that timely treatment in the form of curettage or segmental resection can be provided...

CASE: A 12-year-old girl with Crouzon syndrome presented to our hospital with scoliosis (114°) and kyphosis from T8 to T12 (138°). After she had been in halo-gravity traction for 2 weeks, we performed posterior correction and fusion surgery from T3 to L3, with a posterior vertebral column resection of T10. She experienced postoperative respiratory failure and remained on a ventilator for 4 weeks. With rehabilitation, the respiratory function had recovered by postoperative week 8. At the 2-year follow-up, there was no loss of correction or any other complication...

A number of textbooks, review articles, and case reports highlight the potential comorbidity of choanal atresia in craniosynostosis patients. However, the lack of a precise definition of choanal atresia within the current craniosynostosis literature and widely varying methods of detection and diagnosis have produced uncertainty regarding the true coincidence of these conditions. The authors review the anatomy and embryologic basis of the human choanae, provide an overview of choanal atresia, and analyze the available literature that links choanal atresia and craniosynostosis...

REVIEW
Saïd C Azoury, Sashank Reddy, Vivek Shukla, Chu-Xia Deng
Craniosynostosis results from the premature fusion of cranial sutures, with an incidence of 1 in 2,100-2,500 live births. The majority of cases are non-syndromic and involve single suture fusion, whereas syndromic cases often involve complex multiple suture fusion. The fibroblast growth factor receptor 2 ( FGFR2 ) gene is perhaps the most extensively studied gene that is mutated in various craniosynostotic syndromes including Crouzon, Apert, Pfeiffer, Antley-Bixler, Beare-Stevenson cutis gyrata, Jackson-Weiss, Bent Bone Dysplasia, and Seathre-Chotzen-like syndromes...

In the United States, one in 60,000 adults live with Crouzon Syndrome (CS) and facial malformations. Phenomenological studies about their lived experiences and quality of life are lacking. The purpose of this participatory action research study was to gain a richer understanding of the perceived biopsychosocial and socioecological factors that impact quality of life for adults living with CS using Photovoice. Another aim was to develop a conceptual framework of quality of life for those experiencing CS to enhance tailored health education and services...
