Schwannomas are not uncommon in the maxillofacial region; however, those with intraoral localization and, in particular, the hard palate are among the least frequently described. In the current case report, we present a 17-year-old girl with a histologically verified schwannoma of the hard palate on the right, originating from the right greater palatine nerve. In her case, despite the lysis of the palatine bone from the tumor compression, the disease is asymptomatic, causing only a weak sensation of local discomfort...

The aim of this retrospective study was to assess the efficacy of recombinant human bone morphogenetic protein-2 (rhBMP-2) with hydroxyapatite (HA) granules and fibrin sealant (FS) in maxillary sinus floor augmentation (MSFA), with a focus on the volume change. Fifty-two of 137 patients who underwent MSFA with rhBMP-2/HA grafting between June 2016 and December 2022 met the study inclusion criteria; 25 had received rhBMP-2/HA without FS and 27 had received rhBMP-2/HA with FS. Computed tomography (CT) images were obtained preoperatively, immediately following the operation, and at 6 months postoperative...

Chondroid syringoma (CS) is a benign, slow-growing mixed tumour that arises from the sweat glands and usually presents in the head and neck area. Histopathological examination is important for proper diagnosis, as CS is often confused with epidermal cysts due to its rare presentation. This article presents a man in his 40s with a right upper lip mass that emerged 6 months prior to presentation. An intraoral surgical excision was performed and the histopathological analysis revealed solid epithelial cells that formed multiple, non-branching ducts lined by cuboidal epithelium...

BACKGROUND: For the surgical treatment of oral cancer, it is sometimes necessary to expand intraoral access within the oral cavity. The "swing approach" that involves lip splitting of the mandible and temporary mandibular osteotomy and the "visor approach" that does not split the lower lip and mandible are mainly used. This study analyzed postoperative outcomes such as complications, recurrence rate, and survival rate by these two approaches. The goal of this study is to evaluate the surgical outcomes of patients using these two approaches, to propose effective perioperative management for oral cancer surgery, and to compare the prognosis of oral cancer patients...

BACKGROUND: Medication-related osteonecrosis of the jaw (MRONJ) is a severe adverse illness linked to antiresorptive therapies (ART), for which there is no therapeutic gold standard. Many factors can influence MRONJ evolution such as cancer type, treatment, comorbidities, and accumulated dose of ART. The aim of this study was to determine the influencing factors of MRONJ treatments success. METHODS: This retrospective study focused on patients treated for MRONJ in a French tertiary centre...

PURPOSE: This review aims to compare and evaluate the outcomes achieved by integrating technological aids and the influence of different implant designs in the reconstruction of post-traumatic orbital defects. METHODS: Electronic searches of the MEDLINE, Embase, Cochrane Library, and Google Scholar databases until March 2023 were conducted. Clinical controlled trials, observational studies, cohort studies, and retrospective studies were identified and included. The predictor variables were the integration of technological aids namely, computer-assisted surgical planning, mirror image overlay, and intraoperative navigation with the utilization of different orbital implant designs (standard orbital meshes, preformed implants, prebent implants, and patient-specific implant [PSI]) during post-traumatic orbital reconstruction...

Facial transplantations have become a clinical reality as the last reconstructive option in severely disfigured patients. To date, clinical outcomes remain unclear. The purpose of this paper was to analyse the outcomes in facial transplantation (FT) and determine the risks and benefits of FT based on short- and long-term outcomes. An electronic literature search was performed across PubMed, EMBASE and the Cochrane Central Register for Controlled Trials (CENTRAL) databases to capture all the relevant records relating to outcomes in FTs from 2005 to 2021...

BACKGROUND: Ameloblastoma is a locally aggressive, benign tumor presenting in the maxilla and mandible prone to recurrence. Resection greatly limits recurrence; however, reconstruction becomes critical to preserve patients' functionality and esthetics. PURPOSE: The aim of this study was to describe surgical resection and reconstructive approaches in the treatment of ameloblastoma and compare clinical outcomes to conservative methods of treatment. STUDY DESIGN, SETTING, SAMPLE: A retrospective case series was completed through analysis of patient records...

This narrative review systematically explores the progression of materials and techniques in alveolar ridge preservation (ARP). We commence by delineating the evolution from traditional ARP methods to cutting-edge alternatives, including platelet-rich fibrin, injectable bone repair materials, and hydrogel systems. Critical examination of various studies reveals these innovative approaches not only accelerate bone healing but also significantly improve patient-reported outcomes, such as satisfaction, pain perception, and overall quality of life...

Surgical reconstruction of mandibular defects is a clinical routine manner for the rehabilitation of patients with deformities. The mandible plays a crucial role in maintaining the facial contour and ensuring the speech and mastication functions. The repairing and reconstruction of mandible defects is a significant yet challenging task in oral-maxillofacial surgery. Currently, the mainly available methods are traditional digitalized design methods that suffer from substantial artificial operations, limited applicability and high reconstruction error rates...

BACKGROUND: Osteoporosis is a common disorder that is characterized by decreased bone density and increased bone resorption. This bone resorption may affect the grafted bone during the maxillofacial reconstruction. PURPOSE: This study aimed to measure the association between osteoporosis and resorption of anterior iliac crest bone grafts used to reconstruct the atrophic anterior maxillae. STUDY DESIGN, SETTING, SAMPLE: This prospective cohort study included female patients requiring bone augmentation of the anterior maxilla...

BACKGROUND: We aimed to retrospectively measure the incidence of missed orbital blowout fracture diagnosis in primary examinations of patients with surgically treated fractures, to identify the causes of the diagnostic oversight, and to describe the clinical manifestations of the fractures. MATERIAL AND METHODS: A retrospective cohort of all patients with unilateral orbital blowout fractures who underwent subsequent surgical fracture reduction at the Department of Oral and Maxillofacial Diseases, Helsinki University Hospital, from January 2011 to July 2021, was gathered...

Background : Maxillofacial microvascular free-flap reconstructions are significant interventions in the management of congenital defects, traumatic injuries, malignancies, and iatrogenic complications in pediatric and young adult patients. Craniofacial disorders within this demographic can result in profound functional, cosmetic, and psychosocial impairments, highlighting the critical need for thorough investigation into factors that may influence procedural success and postoperative quality of life. This retrospective chart review aims to examine the outcomes and potential influencing factors, aiming to offer valuable insights into optimizing the effectiveness of these reconstructions and improving patient outcomes...

(1) Background: Orbital wall fractures are common in maxillofacial trauma, and artificial implants are often used for reconstruction. However, there has always been concern about infection because implants are directly exposed to the airway. This study was conducted to determine the effectiveness of a combination of resorbable plates and antibiotic-impregnated collagen sheets in reconstructions of orbital fractures and to determine whether it had an effect in reducing postoperative antibiotic use. (2) Methods: The retrospective study was conducted on 195 patients who underwent orbital wall reconstruction from March 2019 to August 2022...

Integra® (Integra LifeSciences) is a well-known dermal regeneration template used in partial and full-thickness wound reconstruction. It can be applied directly on to vascular tissue to create a bed for a skin graft, which is often placed in a second surgery. We present our experience of its novel use in oral and maxillofacial surgery patients, using it directly on bone and cartilage (avascular tissue) without further skin grafting. Patients who required full-thickness excision of lesions down to bone or cartilage and who were treated using Integra® were included...

Treatment of edentulous and atrophic mandibular fractures is extremely difficult. Generally, mandibular fractures are repaired and fixed as internal fixation using a reconstruction plate or miniplates with intra- or extraoral approach. Few cases in which external fixation including a transmucosal fixation was performed have also been reported. We report a case of atrophic and edentulous mandibular fracture which was healed by the fixation using dental implants and implant-supported bridge.

INTRODUCTION: Noma is a polymicrobial necrotizing infection of the mouth and face which destroys the soft and hard tissues of the oral and paraoral structures. Malnutrition, poverty, lack of basic hygiene, and chronic disease state etc., possess a risk of developing noma. Noma neonatorum is a progressive gangrenous disease affecting the premature infants. AIM: We present a rare case of noma in an 18 months toddler with a chronic debilitating condition predisposing to the disease progression...

BACKGROUND: Reconstruction of large mandibular defects requires reestablishment of mandibular continuity with bone and soft tissue. The microvascularized fibula flap (MFF) has the advantage of providing both, with adequate length, low resorption rate, low infection risk and possibility of dental implant insertion. It can be adapted to mandibular defects in many different ways. PURPOSE: This retrospective study will present and evaluate the results of the male-female joint technique for flap positioning and fixation...
