Total mandibular reconstruction is one of the most challenging modalities in maxillofacial surgery. In this article, we try to introduce a method of total mandible reconstruction. We report a 25-year-old male patient with complete involvement of the mandible by Langerhans cell tumor. The patient underwent total mandibulectomy and reconstruction with bone allograft harvested from a donor who had died the day before. The patient has good functional and aesthetic results in a long time. It seems that bone allograft can be a good alternative to other methods in total mandibular reconstruction...

Hemangiomas are benign tumors representing only 0.7 to 1% of all bone tumors; those that arise in the zygomatic region are rarely described in the literature. Here, we describe the case of a 55-year-old woman with a mass in the right orbitozygomatic region. She was diagnosed on the basis of preoperative clinical manifestations, data from an earlier histopathological examination, and computed tomography (CT). The CT scan revealed a lesion in the right zygomatic region at the level of the cancellous component...

The aim of this study was to present a new surgical technique used to remove benign mandibular tumors with minimal damage to the inferior alveolar nerve. The pull-through technique was shown using an ameloblastoma surgical resection as an example. This technique consisted in the reconstruction of the lower jaw associating the resection of the lesion with nerve repair at the same surgical time. The resection was performed using the pull-through technique and the inferior alveolar nerve was preserved. After 6 months, the patient presented a recovery of approximately 80% of sensory function...

Bilateral masseter muscle hypertrophy is an alteration in shape and thickness of the masseter muscles that can modify the width of the lower face causing aesthetic and functional problems. A 21-year-old man was referred to the Department of Maxillofacial Surgery at the Civil Hospital in Brescia by his dentist for an evaluation of his facial appearance with a square-face type. To reduce the undesirable facial appearance, a surgical intraoral approach was performed; the procedure includes the bilateral dissection of the masseter muscle, partial lipectomy, and the ostectomy of the mandibular angle assisted by a surgical guide built on a stereolithographic model...

Blunt trauma to the parotid resulting in the formation of a sialocele is rare, with only three cases identified in the literature. We present a unique case involving a 32-year-old man with blunt trauma resulting in a left mandibular angle fracture. The patient underwent open reduction and internal fixation of the left mandibular angle fracture via transoral approach. At follow-up, after resolution of the edema from the injury, a sialocele was noted in the region of the left anterior parotid gland. The patient was treated conservatively with antisialagogues, pressure dressings, and multiple percutaneous aspirations that ultimately resulted in resolution of the sialocele...

Bisphosphonate-related osteonecrosis of the jaws (BRONJ) has emerged as an important and increasingly common comorbidity, especially in patients undergoing long-term treatment with high doses of bisphosphonates. The management of BRONJ remains controversial. Surgical treatment is necessary in severe cases. Treatment of the bone requires sequestrectomy or resection. Given the lack of sufficient mucosa to perform the operation and fragility of margins in many patients, local flaps are crucial. We report two cases of stage-3 BRONJ presenting secondary infection with Actinomyces , receiving treatment consisting of marginal resection of the necrotic bone, reinforcement with a reconstruction plate, and reconstruction of soft tissues using a submental perforator artery flap ipsilateral to the lesion...

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...

A case report of monozygotic (MZ) twins with Crouzon syndrome was previously published to highlight variables in clinical presentation. The postnatal and epigenetic causes for this variation are not well understood. An 8-year follow-up discusses their pertinent clinic course with consideration of genetic and nongenetic variables. The phenotypic and symptomatic obstacles encountered since their initial assessment are reviewed, and the use of three-dimensional Medical Modeling (Golden, CO) as a preoperative planning strategy is addressed...

The aim of this article is to determine hearing and mortality outcomes following temporal bone fractures. Retrospective chart review was performed of 152 patients diagnosed with a temporal bone fracture presenting to the emergency room at a tertiary care referral center over a 10-year period. Utilizing Patients' previously obtained temporal bone computed tomographic scans and audiograms, fractures were classified based on several classification schemes. Correlations between fracture patterns, mortality, and hearing outcomes were analyzed using χ(2) tests...

Intermaxillary fixation (IMF) is a basic and fundamental principle in the management of patients with fractures of the maxillomandibular complex. There are several shortcomings related to the conventionally recommended tooth-mounted devices that are used to achieve IMF. To circumvent these, the use of bone-borne screws has been advocated. We present a series of maxillary fractures treated with IMF screws. Over a 12-month period, 15 cases of maxillary fracture were managed with open reduction and bone plate fixation...

Care for patients with cleft lip and palate is best managed by a craniofacial team consisting of a variety of specialists, including surgeons, who are generally plastic surgeons or otolaryngologists trained in the United States. The goal of this study was to compare the surgical approaches and management algorithms of cleft lip, cleft palate, and nasal reconstruction between plastic surgeons and otolaryngologists. We performed a retrospective analysis of the American College of Surgeons' National Surgical Quality Improvement Program Pediatric database between 2012 and 2014 to identify patients undergoing primary repair of cleft lip, cleft palate, and associated rhinoplasty...

Pedicle flaps based on the external maxillary (facial) artery were introduced during the World War I, precisely a century ago. Today they remain effective tools in facial soft-tissue repair. Recently, pedicle flaps based on the internal maxillary (sphenopalatine) artery have been chosen to reliably close dural defects after endoscopic skull-base surgery. Pedicle flaps, "biologic" to the extent they are based on a defined arterial blood supply, are the lasting contributions-the diuturnity-of Johannes ("Jan") Fredericus Samuel Esser (1877-1946) of Leiden, Holland, and Chicago (IL)...

Despite a paradigm shift in anesthesia and trauma airway management, the craniomaxillofacial fracture (CMF) patients continue to pose a challenge. A prospective study was planned between April 2007 and March 2015 to investigate the safety, efficacy, utility, and complications of anterior submandibular approach for transmylohyoid intubation (TMI) in CMFs using an armored endotracheal tube (ETT). Out of 1,207 maxillofacial trauma cases reported, this study recruited 206 patients (152 males and 54 females) aged between 21 and 60 years...

Application of surgical stents for implant placement via guided flapless surgery is increasing. However, high cost, need for some professional machines, and not taking into account the soft-tissue parameters have limited their application. We sought to design and introduce a technique named in-office guided implant placement (iGIP) to decrease the cost by using available devices in office and enhance the applicability of surgical stents. A customized surgical stent was fabricated based on prosthetic, soft- and hard-tissue parameters by taking into account the amount of available bone (using the computed tomographic [CT] data), soft-tissue thickness and contour (using a composite-covered radiographic stent), and position of the final crown (by diagnostic cast wax up and marking the final crown position with composite)...

Periorbital injury can present with various permutations of bone trauma, soft-tissue edema, and hematomas that might involve proptosis and restricted motility. We report a case of a 32-year-old patient who sustained a traumatic orbital compartment syndrome simultaneously with a large, significantly displaced, orbital-floor blow-out fracture. Clinical signs consistent with both conditions were elicited. The initial management was as for orbital compartment syndrome. The clinical diagnosis was confirmed with computed tomographic imaging...

Orbital floor fractures pose a grave threat for injury to the infraorbital nerve, resulting in the patient suffering from a disturbing paraesthesia. It is challenging for the operating surgeon to release and secure the entrapped nerve with reconstruction of the orbital floor. We present an interesting case of orbital floor fracture with entrapped infraorbital nerve, wherein we have decompressed the nerve and provided it, a new course.

Orbitocerebral impalement by inanimate objects is a relatively uncommon event. If orbitocerebral impalement is suspected, management entails prompt referral to a trauma facility with neurosurgical, neuroanesthesiological, craniomaxillofacial, and ophthalmological expertise. The aim of this report is to describe the unique mechanism and perioperative considerations of a remarkable, deep orbitocerebral impalement from a walker brake lever through the orbital roof after a fall from standing. We discuss clinical vignette, evaluation, anesthetic approach, and considerations and review the literature on the epidemiology, pathophysiology, surgical and anesthetic management, and prognosis of this traumatic mechanism...
