Definitive Correction of Associated Maxillomandibular Deformities in Treacher Collins Syndrome

Abstract

Treacher Collins syndrome presents with characteristic findings in the maxillomandibular skeleton. There is a unique pattern of cephalometric measurements for individuals with Treacher Collins syndrome, and there are different levels of severity. Some form of maxillomandibular orthognathic surgery is nearly always indicated. Obstructive sleep apnea is a frequent malady afflicting these individuals, and correction of the maxillomandibular complex to a position of relative normalcy has the direct benefit of aiding expansion of the airway. Routine dental care from an early age and comprehensive orthodontic treatment is very important. Severe skeletal open bites are often present and can cause significant masticatory dysfunction. Recognizing the severity of the deformities and understanding the full scope of surgical options is critical to providing the best possible care. Data acquisition can be done in a completely digital workflow with digital intra-oral scanners and cone-beam CTs. The surgical plans are individualized for each patient with 3D computer-aided surgical planning. Customized cutting guides and surgical hardware can now be acquired routinely, and their indications for use seem to be growing. The goal still remains to provide high-quality, safe, predictable surgical treatment options to individuals with Treacher Collins syndrome to help them with form and function.
