OBJECTIVES: Recurrence of cranial bone fusion following surgical resection in craniosynostosis patients commonly requires additional surgical procedures. Surgical implantation of engineered 3D scaffolds that control tissue mineralization could be utilized to diminish recurrence of fusion. This study investigated the ability of composite scaffolds to control tissue mineralization when cultured in vitro. SETTING AND SAMPLE POPULATION: Precision-engineered scaffolds with calvarial cells were cultured in vitro at the Department of Orthodontics and Pediatric Dentistry, University of Michigan...

INTRODUCTION: In esthesioneuroblastoma, greater disease extent and Kadish staging correlate with greater recurrence, complications, and mortality. These advanced stage malignancies require extensive resections and aggressive adjuvant therapy. This increases the risk of complications such as cerebrospinal fluid leak, neurologic deficits, and osteomyelitis. We present our case series and then analyze the literature to ascertain whether advanced stage tumors corresponds to greater rates of complications...

Craniofacial (CF) tissue is an architecturally complex tissue consisting of both bone and soft tissues with significant patient specific variations. Conditions of congenital abnormalities, tumor resection surgeries, and traumatic injuries of the CF skeleton can result in major deficits of bone tissue. Despite advances in surgical reconstruction techniques, management of CF osseous deficits remains a challenge. Due its inherent versatility, bioprinting offers a promising solution to address these issues. In this review, we present and analyze the current state of bioprinting of bone tissue and highlight how these techniques may be adapted to serve regenerative therapies for CF applications...

The reconstruction of large cranial and scalp defects is a surgical and esthetic challenge. Single autologous tissue transfer can be insufficient due to the defect size and the anatomic complexity of the recipient site. Alloplastic patient-specific preformed implants can be used to recover hard tissue defects of the neurocranium. Nevertheless, for long-term success adequate soft tissue support is required. In this brief clinical study, the authors describe calvarian reconstruction in a 33-year-old patient with wound healing disorder after an initial resection of ependymoma...

We retrospectively analyzed 14 patients with locally advanced squamous cell carcinoma of ethmoid sinus (LASCC-ES) for the feasibility of anterior craniofacial resection (ACFR). Ethmoid cancer treatment comprised alternating chemoradiotherapy (ALCRT; n = 1), concomitant radiotherapy and intra-arterial cisplatin (RADPLAT; n = 4) and ACFR (n = 9). The 3- and 5-year overall survival (OS) rates of patients were 47.6 and 39.6%, respectively. The 3-year local control (LC) rates of chemoradiotherapy (CRT; ALCRT and RADPLAT) (n = 5) and ACFR (n = 9) groups were 0 and 66...

Olfactory neuroblastoma (ONB) is a potentially curable disease, despite being an aggressive malignancy with a poor natural history. Our goal was to evaluate management outcomes for patients with ONB treated at our institution. Our prospective database for brain tumors and the pathology registry of head and neck cancers at Oslo University Hospital were searched to identify all patients treated for ONB between 1998 and 2016. Variables extracted from these databases, supplemented by retrospective chart reviews, underwent thorough analysis...

Osteoblastomas are benign bone tumors, which are unusual in the craniofacial skeleton, being most often observed in the axial skeleton and long bones. The most common site in the maxillofacial region is the mandible and the involvement of the maxilla and paranasal sinuses is extremely rare. Although it is a benign lesion, the aggressive variant raises concerns due to its huge local destructive potential and tendency to relapse. In this clinical case, an aggressive osteoblastoma is described in a 7-year-old patient...

The most common primary sites for bone metastases in men are lung, prostate, kidney, thyroid or bladder. Colorectal origin is rare. Few studies have described this type of metastases; the axial skeleton or the pelvis are the most common metastasis locations. Craniofacial location is exceptional. We here report the case of a 38 years old man treated for metastatic rectal cancer metastasized to temporal bone. He initially had undergone surgical procedure for low anterior resection, tumor was classified as pT3N0M0; 24 months after the patient had left exophthalmos revealing a temporal tumoral process...

Desmoplastic fibroma (DF) of bone is considered a benign but locally aggressive tumor of fibroblastic origin. DF is rare, representing less than 1% of all bone tumors. Approximately 84% of patients are younger than 30 years. DF has a slow but aggressive growth potential and can recur locally when it has not been completely excised. Complete resection is the treatment of choice to decrease recurrence and morbidity. Mandibular reconstruction is mandatory in pediatric patients to ensure correct craniofacial development...

The psammomatoid ossifying fibroma (POF) is a rare and benign fibro-osseous lesion predominantly affecting the paranasal sinuses and orbits of children and young adults. The diagnosis and management of the lesion remains challenging. The present study reported a rare case of a large POF in a 39-year-old male patient. The patient had a 30 year history of a slowly growing tumor and this had resulted in right craniofacial deformity, as well as right lateral displacement of the eye ball. Due to the large tumor size, surgical removal of the lesion was the predominant treatment...

OBJECTIVES: Growth hormone-secreting pituitary adenomas in adults can result in severe craniofacial disfigurement and potentially fatal medical complications. Surgical resection leading to remission of the disease is dependent on complete surgical resection of the tumor. Lesions that invade the cavernous sinus may not be safely accessible via an endonasal transsphenoidal surgery (TSS), and the rates of biochemical remission of patients with residual disease vary widely in the literature...

Melanotic neuroectodermal tumor of infancy is a rare congenital pigmented neoplasm of neural crest origin, locally aggressive, growing rapidly and developing during the 1st year of life. It most commonly arises from the maxilla, cranial vault, and mandible. Occasionally, it exhibits malignant behavior with local lymph nodes involvement. Cases misdiagnosed and left untreated for a long time can present challenges due to the tumor mass and infiltration. In these cases, adjuvant chemotherapy can be extremely helpful before radical excision...

Xinni Xu, Sein Lwin, Yew Kwang Ong
The pericranial flap is a well-vascularized, robust flap that is used to reconstruct anterior skull base defects following resection of skull base tumors. Failure of this flap is uncommon. However when it occurs, the consequences are potentially disastrous and it poses a challenge to further reconstruction. The authors report the first patient of onlay pericranial flap breakdown following endoscopic craniofacial resection. Possible contributing factors are identified and further management is discussed. With the endoscopic approach being increasingly utilized for craniofacial resection, it is imperative to be mindful of these factors to minimize the risks of onlay pericranial flap failure...
