The fibular free flap has become the gold standard for mandibular reconstruction. Despite its vast array of benefits, this procedure has the potential for several complications. In the pediatric setting, the immature skeleton sets the stage for an increased risk of future skeletal abnormalities, both in the jaw, and in the donor site. Herein we describe the case of a toddler who underwent mandibular reconstruction using a fibula free flap and, years later, subsequently developed ankle instability as a result of residual fibula migration...

OBJECTIVES: Alhough typically prescribed in oncology, bisphosphonates (BPs) are also employed in rheumatology, particularly for the treatment of osteoporosis, sometimes resulting in complications, such as osteonecrosis of the jaw. Because of different opinions between rheumatologists and dentists on BP use, this study aimed to assess the views of dentists regarding administration of BPs in rheumatology. METHODS: A questionnaire was sent to 880 dentists from the Auvergne region of France to determine their views on BP treatment...

The purpose of this article is to review 1) mandibular advancement device (MAD) - indication, treatment success, and side effects; 2) maxillomandibular advancement (MMA) surgery of the jaws - indication, treatment success, and side effects; and 3) current perspectives. Both MAD and MMA are administered to increase the upper airway volume and reduce the collapsibility of the upper airway. MAD is noninvasive and is indicated as a first-stage treatment in adult patients with mild-to-moderate obstructive sleep apnea (OSA) and in patients with severe OSA unable to adhere to continuous positive airway pressure (CPAP)...

Osteonecrosis of the jaws is an emerging pathological condition characterized by un-exposure or exposure of the necrotic bone, independently from the etiology. This term is usually referred to medication-related osteonecrosis of the jaws due to severe adverse reaction to certain medicines, as bisphosphonates, used for the treatment of cancer and osteoporosis. The management of patients with Bisphosphonate-Related Osteonecrosis of the Jaws (BRONJ) remains challenging because surgical and medical interventions may not eradicate this pathology...

The aim of this case series was to reveal the difficulties in diagnosing fibro-osseous lesions with radiological and histopathological examinations and quantify the potential risk of infection to fibro-osseous legions. To analyze the concordance between radiological and histopathological diagnoses, this retrospective case series included patients who were clinically diagnosed with fibro-osseous lesions via radiological findings and excluded the patients who did not undergo histopathological examinations. This study also included the patients in whom histopathological results confirmed fibro-osseous legions when preoperative radiological diagnosis did not include fibro-osseous legions...

BACKGROUND: Multiple myeloma is characterised by monoclonal paraprotein production and osteolytic lesions, commonly leading to skeletal-related events (spinal cord compression, pathological fracture, or surgery or radiotherapy to affected bone). Denosumab, a monoclonal antibody targeting RANKL, reduces skeletal-related events associated with bone lesions or metastases in patients with advanced solid tumours. This study aimed to assess the efficacy and safety of denosumab compared with zoledronic acid for the prevention of skeletal-related events in patients with newly diagnosed multiple myeloma...

Occlusal and esthetic rehabilitation of jaw deformities in patients with partially edentulous maxilla are challenging procedures. This article describes a patient involving a skeletal Class III, 36-year-old male patient with a single bilateral anterior partially edentulous maxilla resulting from injuries sustained in a motor vehicle accident; his anterior teeth had been lost for more than 10 years. His lip protruded from the lateral view due to the proclined upper incisors and mandibular protrusion.Because of the facial deformity and inadequate prosthesis of the maxilla, the prosthesis had dropped out repeatedly...

Langerhans cell histiocytosis (LCH) is a childhood pathology with a peak of incidence ranging from 1 to 4 years of age, though diagnosis is often made in adult age. LCH is clinically classified into three types: eosinophilic granuloma, Hand-Schuller-Christian disease and Abt-Letterer-Siwe disease. We report a case of Hand-Schüller-Christian disease with diabetes insipidus, skull and maxillary involvement in a 16-year-old boy referred to our observation for gradual increase in mobility of the teeth and subsequent gradual loss of the second premolars and the first molars of the upper jaw...

INTRODUCTION: Zygomatic implant placement can be the best option for restoring masticatory function of an extremely atrophic upper jaw, but the procedure is more invasive than conventional implant placement and can be associated with complications. PRESENTATION OF CASE: We report a complication that occurred during a secondary corrective surgical procedure four years after zygomatic implant placement. The patient was a 54-year-old female who had been edentulous for 25 years...

OBJECTIVES: Reproduction of the exact preoperative proximal-mandible position after osteotomy in orthognathic surgery is difficult to achieve. This clinical pilot study evaluated an electromagnetic (EM) navigation system for condylar positioning after high-oblique sagittal split osteotomy (HSSO). STUDY DESIGN: After HSSO as part of 2-jaw surgery, the position of 10 condyles was intraoperatively guided by an EM navigation system. As controls, 10 proximal segments were positioned by standard manual replacement...

OBJECTIVE: Three-dimensional (3-D) surgical simulation has become popular, but the accuracy of such simulation is difficult to assess. Because maxillofacial soft tissue profiles vary with posture, we compared such profiles obtained in the supine and sitting positions. STUDY DESIGN: In total, 28 patients with skeletal Class III jaw deformities underwent computed tomography in the supine position and 3-D optical scanning in the sitting position. The 2 sets of 3-D data were superimposed, and linear and volumetric differences were calculated...

Fibrous dysplasia (FD) is a disturbance of the mesenchymal tissue that accounts for 2.5% of all bone tumors and more than 7% of nonmalignant bone tumors. In the craniomaxillofacial region, FD affects the calvaria, skull base, zygoma, and jaws, the prevalent site being the maxilla (50% of cases). Therapy for craniomaxillofacial FD is surgical. The goals of surgery are to prevent functional disorders and restore facial symmetry, volume, and contour. In this article, we present a case of a young female patient affected by right orbital-zygomatic-maxillary FD...
