OBJECTIVES/HYPOTHESIS: Reconstruction of craniofacial cartilagenous defects are among the most challenging surgical procedures in facial plastic surgery. Bioengineered craniofacial cartilage holds immense potential to surpass current reconstructive options, but limitations to clinical translation exist. We endeavored to determine the viability of utilizing adipose-derived stem cell-chondrocyte co-culture and three-dimensional (3D) printing to produce 3D bioscaffolds for cartilage tissue engineering...

Synostotic anterior plagiocephaly is a rare pathological cranial malformation. Therapeutic options are rarely studied due to the rarity of the malformation and difficulties in diagnosis and care management. The objective of this study was to analyze the results obtained with the Lille protocol based on 62 CT-scans done before and after surgery in 31 patients. A specific analysis was designed for this work. Nine cephalometric measures enabled to evidence on each CT-Scan the corrections made on the fronto-orbital bandeau and the potential impact of surgery on the craniofacial structures...

BACKGROUND: Rhinoplasty is among the most popular aesthetic surgical procedures selected by teenagers. When it comes to teenagers' rhinoplasty, almost all surgeons believe that modified techniques should be considered because the nose is still growing. In this article, we prospectively followed teenagers who had undergone septorhinoplasty to assess the safety of procedure and its possible complications. METHODS: All the patients who were under 18 years old but for those who had a bleeding disorder, allergic rhinitis, and cleft lip nose were included in the study...

Melanotic neuroectodermal tumor of infancy (MNTI) is a rare entity primarily affecting the craniofacial bones during the first year of life, with only 5 reported cases involving peripheral long bones. We herein present a case of MNTI in the tibia of an infant, with a somewhat atypical presentation, and a noteworthy clinical course characterized by progressive spontaneous resolution without therapy, thus sparing the child the trauma of amputation. There is no evidence of active residual or recurrent disease with 13-year follow-up...

Skull reconstruction is an important and challenging task in craniofacial surgery planning, forensic investigation and anthropological studies. Existing methods typically reconstruct approximating surfaces that regard corresponding points on the target skull as soft constraints, thus incurring non-zero error even for non-defective parts and high overall reconstruction error. This paper proposes a novel geometric reconstruction method that non-rigidly registers an interpolating reference surface that regards corresponding target points as hard constraints, thus achieving low reconstruction error...

Thanks to advances in neuroscience, biopsychosocial models for diagnostics and treatment (including physical, psychological, and pharmacological therapies) currently have more clinical support and scientific growth. At present, a conservative treatment approach prevails over surgery, given it is less aggressive and usually results in satisfactory clinical outcomes in mild-moderate temporomandibular disorder (TMD). The aim of this review is to evaluate the recent evidence, identify challenges, and propose solutions from a clinical point of view for patients with craniofacial pain and TMD...

Drains are essential in most surgeries. Primary need is elimination of dead space and related consequences but drains per se do have their share of complications, one of them being dislodgment. Complications related to dislodgment can range from inactive drains to damage to critical areas like anastomosis sites. Securing drains using this technique was described by Jayaraj et al. in 1988. Since then, no study was done to determine the efficacy and outcomes of this method. An audit was conducted from 2009 to 2014 at SDM Craniofacial unit to determine the utility of drain fixation...

BACKGROUND: The use of MRI for virtual surgical planning has not yet been described. In the US, over 600,000 CT scans are performed on children annually, who are at higher risk for developing cancer caused by ionizing radiation compared to adults. The aim of this study is to demonstrate that 3D printed craniofacial surgical guides created from Black Bone MRI are comparable in accuracy to those created from CT scans. METHODS: A mock craniosynostosis surgery translocating four calvarial segments was virtually planned and performed in ten cadavers...

The complexity of the craniofacial patient mandates the cooperation of a multidisciplinary team that can systematically evaluate each individual and ensure that a protocol-driven pathway is undertaken for the best patient care. Oral and maxillofacial surgeons contribute to surgical care in this setting with specific knowledge of growth and development of the face. This enables optimum timing for early skeletal correction where appropriate, and definitive surgery following the cessation of growth to maximize function and aesthetics...

This article describes 2 patients with complex facial asymmetry characterized by hemiarhinia, microorbitism, palpebral fissure shortening, ipsilateral canthal dystopia, maxillomandibular hypoplasia, and occlusal plane inclination. These unusual phenotypes are part of the oculoauriculo-vertebral spectrum. Their devastating functional, esthetic, and psychologic effects demand the use of different craniofacial surgery techniques, in order to alleviate the profound impact of these pathologies. Initial skeletal balance through bimaxillary distraction osteogenesis and orbital expansion sets the basis for further reconstruction of the nose and periorbital area with local tissue...

BACKGROUND: Gene-activated matrix (GAM) induces sustained local production of growth factors to promote tissue regeneration. GAM contains a plasmid DNA (pDNA) encoding target proteins that is physically entrapped within a biodegradable matrix carrier. GAM with a pDNA encoding the first 34 amino acids of parathyroid hormone (PTH 1-34) and a collagen matrix enhances bone regeneration in long bone defects. Demineralized freeze-dried bone allograft (DFDBA) is a widely used osteoinductive bone graft...

The current surgical techniques used in cleft repair are well established, but different centers use different approaches. To determine the best treatment for patients, a multi-center comparative study is required. In this study, we surveyed all craniofacial departments registered with the German Society of Maxillofacial Surgery to determine which cleft repair techniques are currently in use. Our findings revealed much variation in cleft repair between different centers. Although most centers did use a two-stage approach, the operative techniques and timing of lip and palate closure were different in every center...

The surgery-first approach (SFA) is a new paradigm in orthognathic surgery. In our experience over the last 10 years, SFA, particularly for the correction of the class III dentofacial deformity and facial asymmetry, has demonstrated high success rates without any major complications. However, many craniofacial surgeons remain concerned about the skeletal stability of SFA. In the present study, the authors aimed to compare the traditional and SFA with regard to the long-term outcomes of vertical skeletal stability using large-scale data...
