Due to their extraordinarily broad differentiation potential and persistence during adulthood, adult neural crest-derived stem cells (NCSCs) are highly promising candidates for clinical applications, particularly when facing the challenging treatment of neurodegenerative diseases or complex craniofacial injuries. Successful application of human NCSCs in regenerative medicine and pharmaceutical research mainly relies on the availability of sufficient amounts of tissue for cell isolation procedures. Facing this challenge, we here describe for the first time a novel population of NCSCs within the middle turbinate of the human nasal cavity...

We conducted a retrospective chart review to examine the efficacy of adenotonsillectomy for the treatment of severe obstructive sleep apnea (OSA) in children. Our study population was made up of 85 patients-58 boys and 27 girls, aged 1 to 17 years (mean: 6.9 ± 4.4)-with severe OSA who had undergone adenotonsillectomy and pre- and postoperative attended polysomnography (PSG) over a 4-year period. Severe OSA was defined as an apnea-hypopnea index (AHI) of >10 events per hour of sleep. Patients who had an underlying genetic or craniofacial anomaly were excluded...

Craniofacial trauma is often associated with orbital and ocular injuries. We report a case of a 21-year-old male with motor vehicular accident, orbital roof blow-in fracture, cerebrospinal fluid (CSF) leak, and left sided globe luxation with corneal abrasion and complete conjunctival denuding. The patient was managed by a multispeciality team and the eyeball was protected by amniotic membrane graft (AMG) biological dressing with novel use of inverted sterile metallic bowl as mechanical protection till the patient stabilized...

REVIEW
Luis Delgado, Avanti Verma, Teresa M O, Stuart Super
Vascular malformations affect the craniofacial skeleton in many ways, depending on the type of the lesion and its location. The lesions may exert a mass effect and cause thinning or thickening of the bone or cause expansion from direct bony infiltration. Orthognathic surgery can be used to correct any malocclusion or open bite deformities after the soft tissues are addressed.

This paper outlines the development and evaluation of a photobook resource to support parents' decision making regarding potential craniofacial surgery for their child. The photobook was developed at a UK Craniofacial Unit and consisted of preoperative and postoperative photographs of patients with craniosynostosis. It was intended to act as a visual adjunct to detailed verbal discussion of surgical treatment options. No changes in the uptake rate of surgery were detected following the introduction of the photobook...

The basis of craniofacial tumor surgery is complete surgical extirpation, preferably en bloc or with free borders. Craniofacial techniques are the gold standard and primary strategies in the treatment of anterior skull base tumors. In the last decade, the reports favoring results of endoscopic techniques have increased. One could conclude that the classical transfacial approaches might become useless, but, in fact, there is little research comparing these techniques.In this article, the authors present their experience with combined craniofacial resection of anterior craniofacial skull base tumors in 9 consecutive patients between January 2013 and July 2015...

OBJECTIVE The treatment of frontoethmoidal meningoencephaloceles (fMECs) in Cambodia was not possible before the development of a program that taught some Khmer surgeons (working at the Children's Surgical Centre in Phnom Penh) how to surgically correct these deformities without any foreign help. The results of that teaching program are discussed in this paper. METHODS Between 2004 and 2009, both local and visiting foreign neurosurgical and craniofacial surgeons (the visitors coming twice a year) worked together to operate on 200 patients, and a report on those cases was published in 2010...

BACKGROUND: Cleft lip and/or palate (CL/P) is a common congenital craniofacial anomaly that may negatively affect an individual's appearance, health-related quality of life, or speech. In Spain, Colombia, and Chile the overall prevalence of CL/P ranges from 0.53 to 1.59 cases per 1000 live births. Currently, there is no patient-reported outcome (PRO) instrument that is specific for patients with CL/P. The CLEFT-Q is a new PRO instrument developed to measure outcomes of treatment in patients 8 to 29 years of age with CL/P...

Orbital hypertelorism is a common congenital craniofacial anomaly in Asians. As Tessier pointed out, the correction of hypertelorism is effectively the correction of the nasal deformity, which is characterized by a broad, flat nose accompanying an increased interorbital distance and a lack of nasal projection. OBJECTIVES: To measure the changes in the orbital and nasal parameters after Tessier box osteotomy and primary aesthetic rhinoplasty, performed concurrently with otogenous costochondral graft...

The mainstay of treatment of craniofacial dysplasia (CFD) remains surgery once clinical observation has been excluded. Nevertheless, disagreement remains about the type of surgical intervention (remodelling versus radical resection). The aim of this paper is to present our experience until 2013 comparing CFD management between 1980 and 2002 and between 2003 and 2013 and to propose our surgical algorithm. From January 2003 to December 2013, 41 new patients (18 males and 23 females) with histologically demonstrated CFD presented to our Department...

Engineering craniofacial bone tissues is challenging due to their complex structures. Current standard autografts and allografts have many drawbacks for craniofacial bone tissue reconstruction; including donor site morbidity and the ability to reinstate the aesthetic characteristics of the host tissue. To overcome these problems; tissue engineering and regenerative medicine strategies have been developed as a potential way to reconstruct damaged bone tissue. Different types of new biomaterials; including natural polymers; synthetic polymers and bioceramics; have emerged to treat these damaged craniofacial bone tissues in the form of injectable and non-injectable scaffolds; which are examined in this review...

Temporomandibular disorders (TMD) are a subgroup of craniofacial pain problems involving the temporomandibular joint (TMJ), masticatory muscles, and associated head and neck musculoskeletal structures. These disorders are subclassified into TMJ articular disorders and masticatory muscle disorders. Patients with TMD most commonly present with pain, restricted or asymmetric mandibular motion, and TMJ sounds during mandibular movements. The prevalence tends to increase with age. Management of TMJ articular disorders consists of a combination of patient education, home-care plan, biobehavioral therapy, physical therapy, orthotic jaw appliance therapy, pharmacotherapy, and/or surgery...

Osseointegrated craniofacial implants have improved retention and patients' perceptions of implant-retained nasal prostheses; however, the determination of the available bone sites for implant placement post-rhinectomy is difficult. This case report describes the use of cone beam computed tomography scanning and computer-assisted virtual planning in conjunction with digital photographs for rehabilitation of a facial defect with an implant-retained silicon nasal prosthesis. Two implants were planned in the anatomical area with adequate bone volume to achieve favorable cosmetic outcomes and accessibility for hygiene maintenance...

In craniofacial surgery, a wide spectrum of pathological conditions are usually treated. The aetiology of these could be congenital, traumatic, infective, post-tumor resection, postradiation, autoimmune, iatrogenic, or other miscellaneous conditions. The surgical approach for the procedures is usually via a coronal incision. In a large proportion of the patients, the frontal bone is removed to obtain intracranial access. The frontal bone is then replaced either in its original form or in a remodeled state. In congenital conditions the supraorbital bar and frontal bone is often also removed, remodeled, and replaced...

PURPOSE: Temporal hollowing deformity (THD) is a visible concavity/convexity in the temporal fossa; a complication often seen following neurosurgical/craniofacial procedures. Although numerous techniques have been described, no study to date has shown the healthcare costs associated with temporal hollowing correction surgery. Thus, the purpose here is to compare and contrast the direct costs related to temporal cranioplasty using various methods including: liquid poly-methyl-methacrylate (PMMA) implants with screw fixation, prebent, modified titanium mesh implants, and customized cranial implants (CCIs) with dual-purpose design...
