BACKGROUND: Several correlations between morphological and/or positional alterations of the jaws and respiratory functional impairments have been reported. Nasal airway obstruction represents a critical issue with no clearly defined gold standard as for its measurement. Rhinomanometry was adopted by multiple Authors to evaluate whether patients with malocclusion developed respiratory functional changes after an orthodontic-surgical treatment. However, there are contrasting findings in the literature regarding the possibility of improving the respiratory function by means of surgically-assisted rapid palatal expansion (SARPE) or bimaxillary repositioning of the bony bases...

Aim. This study aims to explain the main steps that characterize the implant-prosthetic rehabilitation in complex combined dental and maxillofacial trauma. Material and Methods. A 20-year-old patient reported an extensive facial trauma which also involved the alveolar process of the maxillary bone. The patient reported a maxillofacial fracture and the loss of teeth 1.3, 1.2, 1.1, and 2.1. A "Le Fort" type 2 fracture was also reported, with the malar bone involvement. After reduction and containment of bone fractures, through appropriate mounting plates, appropriate functional and aesthetic rehabilitation of the patient were replaced thanks to a temporary removable prosthesis...

BACKGROUND: Fractures of mid-face were first described by Le Fort and are classified into three categories - Le Fort I, Le Fort II and Le Fort III. The pterygoid processes of the sphenoid bone are fractured in all the three categories of Le Fort fractures as the sphenoid bone connects the cranium vault to the facial bones. Fractures of the pterygoid processes without associated Le Fort fractures are rare and are usually associated with fractures of the mandible, temporal bone or other facial bones...

BACKGROUND/AIM: Le Fort lines have traditionally been considered as zones of weakness in the mid-facial skeleton although the structural basis of increased bone fragility at these sites has not yet been investigated. Considering recent findings of occlusal loading-related regional heterogeneity in the mid-facial bone micro-architecture, the aim of this study was to explore whether such heterogeneity in cortical and cancellous bone micro-architecture may contribute to increased fragility at Le Fort fracture sites...

INTRODUCTION: Faciomaxillary fractures (FMF) occur in a significant proportion of trauma patients. Nearly all polytrauma patients and even those with isolated FMF are managed under general anesthesia for definitive management. We propose the use of regional nerve blocks as a safe and effective means for open reduction and fixation of isolated FMF. AIM AND OBJECTIVES: The aim is to evaluate the feasibility, effectiveness and safety of base of skull maxillomandibular and distal trigeminal nerve blocks in the management of FMF...

The aim of this study was to determine whether non-linear three-dimensional finite element analysis (3D-FEA) can be applied to simulate pterygomaxillary dysjunction during Le Fort I osteotomy (LFI) not involving a curved osteotome (LFI-non-COSep), and to predict potential changes in the fracture pattern associated with extending the cutting line. Computed tomography (CT) image data (100 snapshots) after LFI were converted to 3D-CT images. 3D-FEA models were built using preoperative CT matrix data and used to simulate pterygomaxillary dysjunction...

PURPOSE: Because of less attention to the sagittal component of maxillary fractures, these fractures are often misdiagnosed or the reduction is missed leading to maxillary transverse discrepancies. Therefore, the purpose of this study was to identify factors associated with good or adverse postoperative outcomes of maxillary sagittal fractures. MATERIALS AND METHODS: This study was a single-center retrospective cohort study. The sample was composed of cases of maxillary sagittal fractures treated at the Department of Oral and Maxillofacial Surgery, Craniomaxillofacial Trauma Unit of Xi'an Jiaotong University (Xi'an, China) from January 2008 through December 2013...

CONTEXT: Slotplates were specifically designed to meet the special requirements of corrective surgeries of the facial skeleton. This design enables small readjustments of bone fragments in the midface and chin area during surgery without complete removal of plates and screws. OBJECTIVE, DESIGN, AND SETTING: The aim of this study was to compare morbidity rates of slotplates versus meshplates after Le Fort I osteotomy, genioplasty and/or zygoma 'sandwich' osteotomy performed in a tertiary care centre...

Septal deviation constitutes an important component of both esthetic deformity and airway compromise in patients with cleft lip and palate (CLP). The posterior parts of the nasal septum presented greater deviation than the anterior parts in patients with complete unilateral CLP. Le Fort I down-fracture provides better access to the nasal septum than intranasal incision during rhinoplasty, especially to the posterior part. This study objectively and subjectively evaluated the nasal function after Le Fort I osteotomy combined with septoplasty in patients with complete unilateral CLP...

PURPOSE: The intraoral quadrangular Le Fort II osteotomy (IQLFIIO) represents a reliable surgical method in cases of midfacial deficiency with good functional, esthetic, and stable long-term results. PATIENTS AND METHODS: In this technical note, we present 3 surgical modifications to previous reports: 1) inferior orbital rim osteotomy by angulated piezosurgical instruments, thereby avoiding the use of chisels in the orbital region; 2) osteosynthetic fixation only laterally at the zygomatic buttress with 2 L-shaped miniplates, thus avoiding paranasal osteosynthesis; and 3) advancement step camouflage in the lateral infraorbital region with a compound mass of autologous bone chips and fibrin glue with the intention to reduce bone block-associated side effects...

BACKGROUND: Recent advancements in computed tomography have enabled the diagnosis of naso-orbito-ethmoid (NOE) fractures to be made in much greater detail. Surgical access to the upper nasofrontal buttress in NOE fractures, however, has remained unchanged over the past decades. All approaches to these fractures using skin incisions have individual drawbacks. The transcaruncular approach is free of the drawbacks of the cutaneous approaches. We further extended the transcaruncular approach for the treatment of NOE and Le Fort II fractures...

We describe the case of a 77-year-old immunocompetent woman with a history of chronic rhinosinusitis who presented with a pathologic Le Fort I fracture after a forceful sneeze. Imaging revealed diffuse sinus opacification and a Le Fort type I complex fracture involving the maxilla, pterygoid plates, clivus, and right nasal bridge. The patient underwent endoscopic debridement of her sinuses, which revealed mucosal dehiscence and otherwise normal healthy bleeding tissue. Anatomic pathology identified necrotic bone with invasive fungal hyphae...

INTRODUCTION: Cricothyroidotomy is an emergency procedure that can be used to secure the airway in situations in which intubation and ventilation are not possible. PRESENTATION OF CASE: We describe a case of 79-year-old male presenting with facial trauma combined with massive upper airway bleeding and swelling in which cricothyroidotomy was required to open the airway in an elderly male patient taking antiplatelet agents who suffered a simple ground-level fall. DISCUSSION: Although emergency airway management is often required in patients with Le Fort fractures, mandibular condyle fractures exhibit a significant relationship with ground-level falls, which are not usually associated with emergency airway management...

Mid palatal fractures are usually present in conjunction with Le Fort I maxillary fractures. Literature on isolated mid palatal fractures as seen in this case is relatively rare. A novel approach for the management of this case was undertaken. A rapid maxillary expander was used to separate palatal segments which healed well. The patient's crossbite and open bite was corrected with elastic use. The protocol of management of malunion of isolated mid palatal fractures is simple with reduced costs, morbidity and higher rates of acceptance...

This study investigates the biomechanical interaction of different mini-plate fixation types (shapes/sizes and patterns) with segmental advancement levels on the Le Fort I osteotomy using the non-linear finite element (FE) approach. Nine models were generated under a standard 1-piece LeFort I osteotomy for advancement with 3, 6 and 9 mm distances and four mini-plates with three fixation patterns including LL, LI, and II patterns placed on the maxillae models by integrating computed tomography images and computer-aided design system...

The Le Fort II osteotomy is a relatively rare operation. The posterior wall osteotomy of the maxillary sinus (MS) is often difficult for Le Fort III. We developed the transmaxillary sinus approach (TSA) for the Le Fort II osteotomy that cuts the posterior wall of the MS directly. This report illustrates this easy-to-use procedure for the Le Fort II osteotomy in syndromic craniosynostosis. This procedure was performed in an 18-year-old patient with Apert syndrome and a 15-year-old patient with Pfeiffer syndrome...

The chemical senses of taste and smell are important to human life, because they play an important role in detecting potential environmental hazards. Humans can identify countless different flavors by the simultaneous perception of taste and smell. Reports of sensory loss after craniocerebral trauma began to appear in the medical literature in the middle 1800s. Dysgeusia associated with head injuries is rare and its reported incidence is 0.4 to 0.5%. This report describes the clinical case of a 32-year-old man with Le Fort I and III fractures treated with surgical reduction and fixation...
