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...

UNLABELLED: Carotid-cavernous sinus fistula (CCF) is a rare complication occurring after the Le Fort osteotomy. We aimed to elucidate the cause of CCF in the Le Fort osteotomy. METHODS: Eleven fresh cadavers were used. After craniotomy, a Le Fort III bipartition osteotomy was then performed. On the left side, both the lateral wall of the maxilla and the pterygomaxillary junction (PMJ) were divided, in addition to the conventional osteotomy line. On the right side, those parts were kept intact...

The midfacial region (MR) is located in the middle-third of the face, composed of several bones and surrounded by complex anatomical structures so that MR fractures (MRFs) often involve other parts of the face. A staging system for classifying MRFs is of paramount importance in order to exchange information among trauma centers. Le Fort described three lines of fractures but still there is no scoring method to stage MRFs. In this article, a classification for MRFs is proposed. It is based on Le Fort's three lines and it defines seven facial units...

The Le Fort I osteotomy is performed under general anaesthesia and specific haemodynamic conditions, i.e. hypotensive general anaesthesia. This study assessed the incidence of the trigeminocardiac reflex (TCR) during the different stages of the Le Fort I osteotomy. Forty-seven patients requiring a Le Fort I osteotomy were included. General anaesthesia was induced. In terms of haemodynamic changes, each patient's oxygen saturation (SpO2), mean arterial pressure (MAP), heart rate (HR), and electrocardiogram (ECG) were monitored by SADAAT Monitoring System and recorded during the different stages of osteotomy: before the induction of anaesthesia, before osteotomy cuts, after finishing the right pterygoid plate osteotomy, after finishing the left pterygoid plate osteotomy, and after performing down-fracture of the maxilla...

This paper proposes an interactive method of model clipping for computer-assisted surgical planning. The model is separated by a data filter that is defined by the implicit function of the clipping path. Being interactive to surgeons, the clipping path that is composed of the plane widgets can be manually repositioned along the desirable presurgical path, which means that surgeons can produce any accurate shape of the clipped model. The implicit function is acquired through a recursive algorithm based on the Boolean combinations (including Boolean union and Boolean intersection) of a series of plane widgets' implicit functions...

This study assessed the impact of oral and maxillofacial trauma and surgical treatment on the quality of life of patients. The study included 66 patients (age range 18-65 years) with facial fractures; 33 required surgical treatment and 33 required conservative (non-surgical) treatment. Quality of life was evaluated by applying the Oral Health Impact Profile questionnaire (OHIP-14) immediately after diagnosis of the trauma (T1), 30 days after surgery or trauma (T2), and 90 days after surgery or trauma (T3). For the control group (conservative treatment), there was a change in quality of life at T1 and T2...

OVERVIEW: Cervical spine injury may present with pediatric patients having sustained fractures of the craniofacial skeleton. Management considerations of the cervical spine often take priority to the fractures of the facial skeleton. The goal of this study was to examine this subset of patients with a focus on initial presentation and need for intervention. METHODS: A retrospective review from 2000 to 2012 of all facial fractures in patients ≤ 18 years at a level 1 trauma center was performed...

REVIEW
J Breeze, C Verea Linares, P Stockton
Pterygomaxillary dysjunction with an osteotome is commonly used to mobilise the maxilla during Le Fort I osteotomy, despite the risk of serious complications. Different instruments and positions have been tried, including dysjunction through the tuberosity. Down fracture by digital pressure alone has also been advocated, but to our knowledge has not been widely adopted. We have therefore reviewed published papers to see if there is any clinical or anatomical evidence for the use of osteotomes to mobilise the maxilla vertically during a Le Fort I osteotomy for either pterygomaxillary dysjunction or dysjunction through the tuberosity...

Transverse maxillary hypoplasia or maxillary constriction in conjunction with unilateral or bilateral posterior cross bites is a common finding in cleft palate patients. These situations are also commonly encountered in adults who have not had recourse to orthodontic treatment in childhood. In adults, after ossification of the mid palatal suture is complete, the accepted means of correcting transverse skeletal discrepancies is by Surgically Assisted Rapid Maxillary Expansion (SARME). The disadvantage of this technique in the Indian scenario is reduced patient acceptance and increased treatment costs...

INTRODUCTION: Superior ophthalmic vein thrombosis is a rare entity, but is associated with significant morbidities. We describe a case in which superior ophthalmic vein thrombosis occurred shortly after severe facial trauma. CASE PRESENTATION: A 77-year-old Japanese man was transferred to our tertiary hospital after a motor vehicle accident. Le Fort III facial bone fractures and a minor cerebral contusion were detected. Follow-up computed tomography scans detected dilatation of his left superior ophthalmic vein on day 3 and thrombosis on day 12; however, no causative carotid cavernous fistula was observed...

BACKGROUND: Biodegradable fixation systems could reduce/delete the problems associated with titanium plate removal. This means less surgical discomfort, and a reduction in costs. AIM: The aim of the present study was to compare the cost-effectiveness between a biodegradable and a titanium system in Maxillofacial surgery. MATERIALS AND METHODS: This multicenter RCT was performed in the Netherlands from December 2006 to July 2009. Included were 230 patients who underwent a bilateral sagittal split osteotomy (BSSO), a Le Fort-I osteotomy, or a bi-maxillary osteotomy and those treated for fractures of the mandible, maxilla, or zygoma...
