Dental and orthodontic management of patients with Apert and Crouzon syndromes

Multidisciplinary Rehabilitation Approach to the Maxillo-Facial Complications of Crouson’s Disease: Case Report and Review

Background:

Craniofacial anomalies present a challenge to all health care practitioners since they necessitate long-term team follow-up, which is difficult to achieve outside of a major center where craniofacial anomalies teams normally collaborate.

Objectives:

The current review with an illustrative case focuses on the representation and review of Crouzon syndrome and its maxillofacial implications. Review of different varieties of gene mutations that produce craniosynostosis syndromes were discussed and focused on seven clinically distinct craniosynostosis syndromes that are precipitated by the mutation in one or more of the fibroblast growth factor receptors genes which affected the maxillofacial region.

Case presentation:

A complete clinical and radiographic case scenario of a patient suffering from Crouzon syndrome was presented, and discussion of the various disciplines and techniques used along the way to achieve the best results, as well as how team collaboration and patient compliance led to the best results were represented. The presented case was treated with orthodontic treatment, Le Fort-I osteotomy, and Le Fort-III osteotomy with extraoral distraction osteogenesis.

Conclusion:

The combination of different orthognathic surgery alternatives (Le Fort-III and Le Fort-I) with distraction osteogenesis and orthodontic treatment produced excellent outcomes with few complications, and the patient was extremely satisfied and cooperative. Early and thorough team-based care for Crouzon syndrome patients should be accessible at specialized craniofacial centers.

Crouzon Syndrome: a Comprehensive Review

Crouzon syndrome is a rare genetic disorder with autosomal dominant inheritance. The underlying pathological process is premature synostosis of the cranial sutures with subsequent phenotypic alterations of the affected person. A review of the literature has been conducted in order to resume the overall characteristics of Crouzon syndrome such as craniomaxillofacial malformations, clinical features, dentoalveolar characteristics, aesthetic impairments, and psychological background, as well as, the different therapeutic procedures, which combine surgical and orthodontic interventions. Facial and functional malformations in individuals with Crouzon syndrome could be significantly improved after a series of surgical and orthodontic procedures in almost all cases. A multidisciplinary treatment approach would provide the best outcomes in affected patients.

Evaluation of the maxillofacial morphological characteristics of Apert syndrome infants

Apert syndrome is a rare craniosynostosis syndrome characterized by irregular craniosynostosis, midface hypoplasia, and syndactyly of the hands and feet. Previous studies analyzed individuals with Apert syndrome and reported some facial and intraoral features caused by severe maxillary hypoplasia. However, these studies were performed by analyzing both individuals who had and those had not received a palate repair surgery, which had a high impact on the maxillary growth and occlusion. To highlight the intrinsic facial and intraoral features of Apert syndrome, five Japanese individuals with Apert syndrome from 5 years and 2 months to 9 years and 10 months without cleft palate were analyzed in this study. A concave profile and a skeletal Class III jaw-base relationship caused by severe maxillary hypoplasia were seen in all patients. The patients exhibited anterior and posterior crossbites possibly due to a small dental arch of Maxilla.
