o underscore the importance of individualized treatment for these challenging patients.
Children with Apert syndrome have hypertelorism and midfacial hypoplasia, which can be treated with facial bipartition (FB), often aided by rigid external distraction. The technique involves a midline osteotomy that lateralizes the maxillary segments, resulting in posterior cross-bites and midline diastema. Varying degrees of spontaneous realignment of the dental arches occurs postoperatively. This study aims to quantify these movements and assess whether they occur as part of a wider skeletal relapse or as dental compensation.
Patients who underwent FB and had high quality computed tomography scans at the preoperative stage, immediately postsurgery, and later postoperatively were reviewed. DICOM files were converted to three-dimensional bone meshes and anatomical point-to-point displacements were quantified using nonrigid iterative closest point registration. CHS828 Displacements were visualized using arrow maps, thereby providing an overview of the movements of the facial skeleton and dentition.
Five patients with Apert syndrome were included. In all cases, the arrow maps demonstrated initial significant anterior movement of the frontofacial segment coupled with medial rotation of the orbits and transverse divergence of the maxillary arches. The bony position following initial surgery was shown to be largely stable, with primary dentoalveolar relapse correcting the dental alignment.
This study showed that spontaneous dental compensation occurs following FB without compromising the surgical result. It may be appropriate to delay active orthodontic for 6-months postoperatively until completion of this early compensatory phase.

Whether a new diagnosis or for ongoing care, the Internet is now an established and massively frequented resource for parents and patients with cleft lip and/or palate. The purpose of this study was to assess the correlation between the first 50 ranked websites for cleft lip and palate via the Google search engine versus those ranked with an objective patient information scoring tool.
The first 50 websites ranked by Google were recorded for the search items “Cleft Lip,” “Cleft Palate” and “Cleft Lip and Palate.” Quality assessment was performed using the DISCERN score, an objective and validated patient information website scoring tool. The Google rank was compared to the DISCERN rank to assess for correlation. The top five websites for each search item were then ranked by blinded cleft health professionals for quality.
Based on Google ranking, 36% of websites were the same across the search terms used. The DISCERN ranking scores demonstrated no evidence of positive or negative correlation when compared to Google ranking. In the top 10 DISCERN ranked websites for each search item, 4 websites appear in the top 10 Google rankings.
This is the first study that demonstrates that high-quality information on cleft lip and palate is available on the Internet. However, this may be difficult and confusing for parents and patients to access due to the ranking system used by internet search engines. Cleft healthcare professionals should be aware of these problems when recommending websites to families and patients.

Zygomaticomaxillary complex fractures are common in midface trauma, with treatment often involving repair using titanium mini plates. However, the need for plate fixation along the zygomaticomaxillary suture on the infraorbital rim remains controversial. This study utilized a previously reported bite force simulator to investigate craniofacial strain patterns following zygomaticomaxillary complex fracture repairs with and without plating of the infraorbital rim. Osteotomies were made to 6 fresh-frozen cadaveric heads to simulate 2 types of zygomatic complex fractures a dipod fracture with osteotomies at the zygomaticofrontal and zygomaticomaxillary sutures, and a tripod fracture with an additional osteotomies at the zygomaticotemporal suture. Repairs with and without the use of a titanium mini plate across the infraorbital rim were compared in both dipod and tripod fractures. Physiologically proportional masticatory loads were applied using the bite force simulator by actuating intrinsic muscle lines of act98) and tripod (P = 0.117) fracture repairs. However, statistically significant differences were found locally at the zygomatic buttress (P = 0.019) and the zygomatic arch (P = 0.027) on the fractured side in dipod fractures. This is the first known study that successfully utilized a mechanical simulator to reproduce physiological intrinsic masticatory loads in a fracture fixation study. This new technology opens avenues for future biomechanical investigations on maxillofacial fracture repairs and other surgical treatments.
Traumatic orbital apex syndrome (TOAS) commonly occurs secondary to trauma and irreversible ischemic optic neuropathy occurs as early as 2 hours after injury. Multiple treatment options have been described, however, there is a lack of consensus regarding the optimal treatment of these patients.
A systematic review of the PubMed Database from 1970 to 2020 was conducted, using the search terms “orbital apex,” “syndrome,” and “traumatic” with the Boolean operators “AND” or “OR.” Papers that did not describe TOAS, describe patient outcomes or treatments, and those without available full English text were excluded. Patients were clustered and compared based on treatment received with the primary outcomes of improvement in vision or ophthalmoplegia.
Three hundred forty-seven papers were identified, of which 22 were included, representing 117 patients with TOAS. A total of 75.9% patients underwent decompressive surgery, 82.6% received steroids, and 72.2% received nerve growth factors. Fewer than 20% of patients were treated with antibiotics, diuretics, hormones, or hyperbaric oxygen.
