CONCLUSION: Unusual primary tumors of the facial nerve should be considered in patients with progressive facial paralysis, especially if this is accompanied by hearing loss or vertigo. Misdiagnosis could increase the difficulties of operation, diminish the chance of facial nerve reconstruction, and increase the likelihood of poor reconstructive outcomes. OBJECTIVE: This paper was to determine the characteristics of facial nerve primary tumors misdiagnosed as tumor-free conditions many years prior, and to describe appropriate treatments...

BACKGROUND: Innervated free muscle transfer using the gracilis muscle or temporalis myoplasty has been successfully utilized for facial reanimation in chronic facial palsy. These techniques are less suited to immediate facial reconstruction in the setting of radical parotidectomy, in which the complexity of the defect, patient age, postoperative radiotherapy, and limited life expectancy pose particular challenges. METHODS: We present a novel description of the use of a chimeric anterolateral thigh (ALT) flap and innervated vastus lateralis to achieve midface static suspension and dynamic reanimation in the setting of radical parotidectomy...

Because of the enormous and continuing increase in cases of skin cancer in the Netherlands, dentists will increasingly see patients with skin cancer. The most common malignant skin cancers are basal cell carcinoma, squamous cell carcinoma and malignant melanoma. With resection of a skin tumour, the oncological principles should be applied. For the closure of the resulting defect, a choice for the individual patient is made out of numerous techniques. Facial reconstructive surgery aims to restore the face in form and function and to maintain the patient's quality of life...

REVIEW
Aparna Dalal
Face transplantation is a complex vascular composite allotransplantation (VCA) surgery. It involves multiple types of tissue, such as bone, muscles, blood vessels, nerves to be transferred from the donor to the recipient as one unit. VCAs were added to the definition of organs covered by the Organ Procurement and Transplantation Network Final Rule and National Organ Transplant Act. Prior to harvest of the face from the donor, a tracheostomy is usually performed. The osteotomies and dissection of the midface bony skeleton may involve severe hemorrhagic blood loss often requiring transfusion of blood products...

Background Ameloblastomas are a rare tumor entity accounting for only 10% of all odontogenic tumors. They mostly originate from the mandible. Only a few cases are known to grow aggressively and to invade the orbit, nasal cavity, or even the brain. Patient and Methods/Case Report We present the case of a 57-year-old patient who was admitted with a huge tumor involving the nasal cavity, the left maxilla, and the anterior fossa. Histologic diagnosis was made by biopsy. A combined two-stage neurosurgical maxillofacial approach was planned...

Clinical data registries are platforms to extract, store, analyze, and disseminate large amounts of clinical data. The type of data contained in clinical data registries varies by the registry, and may include patient demographics, clinical examination findings, imaging and laboratory results, procedures performed, and patient-reported outcomes. When large numbers of participants submit data to a clinical data registry the data can then be analyzed in aggregate to answer new clinical questions. Analyses on the data may be performed to show outcomes over time, compare procedures, evaluate care patterns, among others...

Jörg Jenatsch, a leading freedom fighter during the Thirty Year's War in Graubünden, Switzerland, was assassinated on carnival 1639. Jenatsch's controversial biography and the unclear circumstances of his death inspired the formation of various legends, novels and films. In 1959, a skeleton discovered in the cathedral of Chur with remains of wealthy baroque clothing was tentatively attributed to Jenatsch. Here, we reassess the skeleton based on a new exhumation. Our multidisciplinary analysis and the head injuries are consistent with reports of the eyewitnesses of the crime, demonstrating that Jenatsch was killed from behind with a semi-sharp implement, supposedly an axe, as well as by a blow with a broad-surfaced object...

BACKGROUND: Conventional reconstructive methods fail to achieve satisfactory results in total eyelid defect cases. Vascularized composite tissue allotransplantation might provide both good appearance and function for these patients. We developed an orthotopic periorbital transplantation model in rats to facilitate further experimentation in this field. METHODS: In anatomical studies, the vascular distribution to and innervation of the periorbital unit were identified and recorded...

Correction of orbito-frontal defects involves a multitude of surgical challenges, and requires careful and detailed planning. In the trauma setting, one must be prepared to deal with injuries to adjacent structures and be able to incorporate their repair into the surgical plan to maximize the functional and esthetic reconstruction for the benefit of the patient. Victims who have sustained trauma of the cranial complex in combination with mid-facial trauma, particularly involving the orbit, present a difficult scenario, especially when future ocular prosthetic rehabilitation is a concern...

In this paper, we present a novel method to super-resolve and recover the facial depth map nicely. The key idea is to exploit the exemplar-based method to obtain the reliable face priors from high-quality facial depth map to improve the depth image. Specifically, a new neighbor embedding (NE) framework is designed for face prior learning and depth map reconstruction. First, face components are decomposed to form specialized dictionaries and then reconstructed, respectively. Joint features, i.e., low-level depth, intensity cues and high-level position cues, are put forward for robust patch similarity measurement...

This paper proposes a real-time method for 3D eye performance reconstruction using a single RGBD sensor. Combined with facial surface tracking, our method generates more pleasing facial performance with vivid eye motions. In our method, a novel scheme is proposed to estimate eyeball motions by minimizing the differences between a rendered eyeball and the recorded image. Our method considers and handles different appearances of human irises, lighting variations and highlights on images via the proposed eyeball model and the L0-based optimization...
