Crouzon syndrome: Virtual planning of surgical treatment by application of internal distractors

Abstract Facial asymmetry is a condition that compromises function and social interactions and, consequently, the quality of life. Orthodontic-surgical treatment may be indicated to achieve a stable occlusion and significant improvement in facial aesthetics. The virtual planning of the maxillary, mandibular and chin movements can be done prior to surgery. These movements can be successfully performed with the use of prototyped guides obtained from virtual planning. The aim of this article is to show the state of the art of treatments of facial asymmetries, and emphasize how important is the multi-disciplinary approach to achieve predictable aesthetic and functionally stable results in a patient with facial asymmetry and chin protrusion.

Dentofacial Deformities

ABSTRACT Dentofacial deformities usually are surgically treated, and 3D virtual planning has been used to favor accurate outcomes. Cases reported in the present article show that orthognathic surgery carried out to correct facial asymmetries does not comprise only one treatment protocol. 3D virtual planning might be used for surgical planning, but it should also be used to diagnose the deformity, thus allowing for an analysis of the best-recommended possibilities for the orthodontic preparation that suits each individual case.

Soft Tissue Volume

Thyroid-associated orbitopathy is the most common cause of unilateral or bilateral proptosis in adults. A mainstay of surgical treatment is orbital decompression utilizing osteotomies to increase the size of the affected bony orbit to accommodate the larger soft tissue volume. Over the past several decades, numerous approaches have been described for orbital decompression. However, given the intricate osseous and soft tissue anatomy within the orbit, orbital decompression is a potentially hazardous intervention. With advances in three-dimensional imaging and virtual planning, extensive orbital decompressions can be performed safely and efficiently. In this report, we describe two cases of three-wall orbital decompressions using three-dimensional planning.

Dento-maxillary anomalies are relatively widespread among the population, eventually leading to serious psychological and lifestyle deterioration. The purpose of this paper is to evaluate the complex orthodontic-surgical treatment in the dento-maxillary anomaly class III Angle. We aim to present the clinical case of a female patient suffering from skeletal third-class, gnathic form, who came to „Omni Dent” clinic in order to complete the second stage of associate orthodontic and surgical treatment. Medical investigations: OPG, CBCT, TRG, digital scanning, dental photography, digital programs, used at collecting data for virtual planning, establishing a complex diagnosis and choosing the best surgical technique for this case, subsequently, with the transfer of the virtual plan in the operating room through surgical guides and occlusal splints. Postoperatively, there was an obvious improvement of the facial appearance, supported by the comparison of pre- and postoperative cephalometric indices: SNA (from 76,6° to 84°), SNB (from 80,6° to 78,8°), ANB (from -4° to 5,2°), Wits (from -9,6° to 0°). Early diagnosis and detailed planning by using modern methods of examination may ensure an efficient rehabilitation of patients suffering from dento-maxillary anomalies.

Orthognathic surgery and orthodontic treatment are required for patients with dentofacial deformities to obtain an ideal facial esthetic with good functioning. Recently, characterized by the surgery-first approach, an integrated orthodontic–surgical treatment has been introduced as an emerging solution to dentofacial deformity treatment. The surgery-first approach is regarded to have less treatment time and quicker enhancement of a facial profile than the conventional orthodontic–surgical treatment. Moreover, the recent advances in computing and imaging have allowed the adoption of 3-dimensional (3D) virtual planning protocols in orthognathic surgery as well as digital orthodontic treatment, which enables a paradigm shift when realizing virtual planning properly. These techniques then allow the surgeon and orthodontist to collaborate, plan, and simulate the dentofacial deformity treatment before performing the whole procedure. Along this line, in this research article, we present an integrated treatment method for the realization of an effective deformity treatment. Specifically, we implemented the integrated 3D technique by combining it with the surgery-first orthognathic approach (SFOA) as a novel treatment method for the patients. The outcomes from the combined treatments of the patients with dentofacial deformity, in practice, have demonstrated that our proposed 3D technique in orthognathics and orthodontics using clear aligner therapy (e.g., Invisalign) can enhance the satisfactory level of the patient since the start of treatment then improve their quality of life. As a result, the combined techniques realize the novel integrated treatment method using 3D technology with the use of 3D imaging and modeling as a promising development trend of dentistry, which fits into the context of Dentistry 4.0 as a key enabler to the concept of sustainable dentistry development.

Crouzon syndrome is one of the most common syndromic craniosynostosis. We present complex course of treatment in a child with Crouzon syndrome presented with multisuture craniosynostosis and hydrocephalus. A 3-months-old boy was admitted with clinical signs of hydrocephalus and turribrachycephaly. Firstly, the hydrocephalus was addressed. The ventriculoperitoneal shunt with programmable valve was implanted. Secondly, in May 2017, posterior calvarial remodeling was done. Finally, after the child recovered, anterior calvarial remodeling with fronto-orbital advancement was performed. This completed the calvarial remodeling in this patient. Child is doing well, so far completing milestones of child development in time. This case presents an extremely complex case of syndromic multisuture craniosynostosis, in which it was necessary to perform the entire calvarial remodeling to correct the deformity and to provide a chance to the brain to grow and develop without constrictions.
