REVIEW
Susan M White
Malignancies in the maxillofacial region are rare but comprise a broad spectrum of lesions. Given the potential for malignancies to mimic dental/sinus/temporomandibular joint pathology or remain asymptomatic, the judicious radiologist will be familiar with the initial and unique malignant changes affecting the dentition, periodontium, and supporting osseous structures on conventional film, dental, and sinus imaging. This article is meant to serve as a complement to the many excellent texts dedicated to advanced imaging techniques for the staging of known malignancies...

Objectives: In order to assess clinical behavior, response to treatment, and factors influencing prognosis of Korean patients with osteosarcoma of the jaws (OSJ). Materials and Methods: A retrospective study of clinical, and pathological records of 26 patients with OSJ treated at the Department of Oral and Maxillofacial Surgery in Yonsei University Dental Hospital from 1990 to March 2017. Results: Of 26 patients, there were 9 men (34.6%) and 17 women (65...

Objectives: TNM staging, especially for lymph node metastasis, is the scoring system most widely used among prognostic factors for cancer survival. Several biomarkers have been studied as serologic markers, but their specificity is low and clinical applications are difficult. This study aimed to establish a scoring system for patients with oral squamous cell carcinoma (OSCC) using platelet (PLT) and mean platelet volume (MPV) levels measured postoperatively and to evaluate their significance as prognostic factors...

Autogenous bone grafts are the gold standard for reconstruction of atrophic jaws, pseudoarthroses, alveolar clefts, orthognathic surgery, mandibular discontinuity, and augmentation of sinus maxillary. Bone graft can be harvested from iliac bone, calvarium, tibial bone, rib, and intraoral bone. Proximal tibia is a common donor site with few reported problems compared with other sites. The aim of this study was to evaluate the use of proximal tibia as a donor area for maxillofacial reconstructions, focusing on quantifying the volume of cancellous graft harvested by a lateral approach and to assess the complications of this technique...

An inverted schneiderian papilloma (ISP) is a rare neoplasm that affects the nasal cavity or a paranasal sinus, especially the maxillary sinus. Although histologically benign, the lesion has a high potential for local destruction, has a high recurrence rate, and presents the possibility of malignant transformation into squamous cell carcinoma. To determine the extent of the injury and possible impairment of adjacent maxillofacial structures, accurate imaging, such as cone beam computed tomography (CBCT), is necessary...

Dental caries and the cysts of jaws are frequently occurring pathologies encountered in a dental practice. Imaging of these dental anomalies is done with radiographic examination. Panoramic radiography/ Orthopantomography (OPG) is a common modality to screen patients with an advantage of ease of imaging and reduced exposure to patients. The panoramic images obtained with this equipment are exploited by noise embedded during its acquisition making the detection of this dental caries difficult. Detection and characterization of dental caries and various other maxilla-facial pathologies can be achieved by the application of computer aided image processing algorithms applied on dental panoramic images...

Objective: To review the clinical-pathology characteristics of 19 relapsed pediatric mature B cell lymphoma and to find the risk factors for recurrence and the feasible treatment after relapse. Method: Data of 212 pediatric B cell lymphomas cases in Beijing Children's Hospital from January 2006 to June 2015 were collected retrospectively. All the patients were treated according to the B cell lymphoma regimen of Beijing Children's Hospital. During the study period, 19 of 212 cases were relapsed; the clinio-pathological characteristics of relapsed patients before treatment and after relapse were analyzed retrospectively, the treatment outcomes after relapse were summarized and the patients were followed-up...

Benign fibro-osseous lesions within the maxillofacial region represent a heterogeneous group of benign entities with overlapping histologic features. Ossifying fibroma, the rarest of these entities, represents a true neoplasm. Juvenile ossifying fibroma (JOF) is considered an aggressive rapidly growing sub-type. It tends to occur in the first or second decades of life. Based on histological and clinical features it can further be classified into two variants, namely juvenile trabecular ossifying fibroma (JTOF) and juvenile psammomatoid ossifying fibroma (JPOF)...

BACKGROUND: Radical surgical resection as a treatment modality for oral cancer often leads to an extensive deficit in both the maxillary and mandibular levels, where the use of a palatal obturator prosthesis (POP) or removable partial denture (RPP). The aim of this study was to evaluate the treatment with POP and RPP in patients treated for oral cancer in the Unit of Prosthetic Rehabilitation of the University Hospital Virgen del Rocío in a period of 20 years. MATERIAL AND METHODS: Retrospective descriptive study during the years 1991 and 2011 analyzing oral cancer type, characteristics, treatment and follow-up...

BACKGROUND: The interest in detailed anatomy of the sella and parasellar regions has resurged recently due to the wide clinical applications of the expanded endoscopic approaches to the skull base. The middle clinoid process (MCP) is a bony structure that can affect wide endoscopic exposure of the sella and parasellar region. OBJECTIVE: To study and analyze the anatomic variations of the MCP in the general population using computed tomography scans. METHODS: A total of 150 maxillofacial computed tomography scans were reviewed to characterize the MCP...

REVIEW
Zachary S Peacock
Several benign pathologic entities that are commonly encountered by the oral and maxillofacial surgeon remain controversial. From etiology to treatment, no consensus exists in the literature regarding the best treatment of benign lesions, such as the keratocystic odontogenic tumor, giant cell lesion, or ameloblastoma. Given the need for often-morbid treatment to prevent recurrence of these lesions, multiple less-invasive treatments exist in the literature for each entity with little agreement. As the molecular and genomic pathogenesis of these lesions are better understood, directed treatments will hopefully lessen the contention in management...

BACKGROUND: Tumors invading both the anterior skull base and the sinonasal area have been traditionally accessed via largely invasive open craniofacial approaches. Minimally invasive extended endoscopic endonasal approaches have recently become increasingly available, but have anatomical limitations and require incremental experience and thus high patient volume. Our objective was to assess the applicability of a novel combination of the minimally invasive supraciliary incision and the limited maxillofacial osteotomy as a combined surgical approach for large tumors invading both the anterior skull base and the sinonasal area...

RATIONALE: Lymphomas take up about 14% of all head-neck malignancies, out of which 97% are non-Hodgkin lymphomas (NHL). The clinical courses, treatment responses, and prognoses of NHLs vary with different subtypes and anatomic sites. In the Chinese population (including the Taiwanese), head-neck NHLs are often seen with the tonsils, nasal cavity, nasal sinus, and the nasopharynx. However, oral NHLs are relatively rare. Delay of diagnosis is also often seen in clinical practice. Thus, we present 4 cases with delayed diagnosis of oral maxillofacial NHLs and discuss their clinical manifestations so as to draw a clue that can remind the doctors to take biopsies in time...

BACKGROUND: The vascular fibula flap is an ideal choice for function and appearance reconstruction of mandible. Despite the high success rate, "late complications" such as Ti plate exposure and local infection related to osteosynthesis are not uncommon. PATIENTS AND METHOD: A retrospective cohort of patients who received vascular fibula reconstruction for mandible from January 2011 to December 2013 from the Department of Oral and Maxillofacial Oncology in a tertiary hospital were charted: clinical, pathological, and therapeutic factors were analyzed for late complications in univariate and multivariate analyses...
