The Craniofacial Collaboration United Kingdom (CC-UK) was established across the 4 Highly Specialized Craniofacial Centres (HSCCs) in the UK in 2015. This is the first wave of data to be analyzed, looking at 3-year-old children with sagittal synostosis who have had primary corrective surgery. This is a comprehensive, homogenous dataset, looking at parental measures of development and behavior. The results indicate that the majority of children are rated by their parents as falling within one standard...

The authors present a modified technique of temporalis muscle transposition technique in cases of longstanding facial paralysis. Slips of the temporalis fascia were passed through the tunnels to reach the contralateral para-median plane. The procedure provides 2 point of fixation to the transferred muscle. Local flaps were used for temporal hollow obliteration and for temporalis muscle elongation. This case series included 11 patients. The modified technique was performed for all patients to reanimate...

Twenty patients who were operated at earlier ages for correction of cleft lip and had a residual unilateral cleft...
Background: Craniosynostosis is a congenital defect that causes ≥1 suture to fuse prematurely. Cranial expansion surgery which consists of cranial vault reshaping with or without fronto-orbital advancement (FOA) is done to correct the skull to a more normal shape of the head as well as to increase the intracranial volume (ICV). Therefore, it is important to evaluate the changes of ICV after the surgery and the effect of surgery both clinically and radiologically. Objective: The aim of this...
Scalp arteriovenous malformations (AVMs) are rare entities that may present as large, tortuous vascular lesions with resultant craniofacial deformity. Radiologic findings include feeding arteries and veins associated with dilated tortuous vessels. Intracranial extension is rare. A 5-year-old African American male presented with an occipital mass presumed to be a dermoid cyst on referral. Further workup revealed the presence of a scalp AVM that demonstrated extension into the left sigmoid sinus. Radiologic...
The goal of this study was to investigate the association between various sinonasal anatomical variations and the morphological features of lateral nasal bone, using paranasal computerized tomography (PNCT) sections. Two hundred and fifty patients who underwent a PNCT scan because of a prediagnosis of nasal septum deviation or sinusitis were included in the study. For each patient, presence of the following anatomical variations was determined on CT sections: length and thickness of nasal bone, thickness...

Vascular malformations (VMs) are benign lesions of blood vessels originated from an error in vascular morphogenesis during the embryologic phase. Generally, when located in the head and neck region VMs occurs in lips, tongue, buccal mucosa, gums, or palate. The VMs are usually asymptomatic, varies in size and may cause facial asymmetries. Different therapeutic modalities are available to treat VMs, which include surgical excision, cautery, cryotherapy, laser therapy, and sclerosing agents. The authors...
Background: The authors report on surgical treatment for 20 patients with craniosynostosis in Japan in collaboration with neurosurgery department since 2007. They could safely expand the skull using distraction devices. Methods: Total number of patients with craniosynostosis joint surgery was 20 (23 surgeries) at the time of this report. All patients were referred from the neurosurgery department. Neurosurgeons decided the patient selection and the surgical indications, and performed osteotomy,...
Calcium hydroxylapatite filler is a popular dermal filler, as it provides long-lasting results. However, it sometimes undergoes unexpected early volume loss, due to rapid gel absorption before neocollagenesis. To compensate for this phenomenon, hyaluronic acid filler was added to calcium hydroxylapatite filler for injection as a mixture. Twenty-five patients who scored 1 or 2 on the Merz 5-point scale for the nasolabial fold and jawline were injected with 3.0 mL of the mixture. The mixture was prepared...

Abstract Objectives Melanoma-associated antigens A had been detected repeatedly in oral squamous cell carcinoma, but not in healthy mucosa. Additionally, patients with MAGE-A expressing cancers are regarded to have a worse survival prognosis, so that MAGE-A are supposed to be part of carcinogenesis. Which role these antigens fulfill within OSCC is still, up today, largely unknown. This study examines the hypothesis that MAGE-A is...
