We describe a case of complex, posttraumatic skull and orbital deformities that were evaluated and treated with advanced computer technology, including virtual surgical planning, three-dimensional (3D) modeling, and printed patient custom implants (PCI) fabricated by 3D printing. A 50-year-old man presented to our craniofacial referral center 1 year after failed reduction of complex left orbital, zygomatic, and frontal bone fractures due to a motorcycle collision. The patient's chief complaint was debilitating diplopia in all fields of gaze...

The free vascularized fibular graft is nowadays the preferred technique for pediatric mandibular reconstruction. Despite the versatility and proven efficacy for restoring the facial appearance and maxillomandibular function, those mandibular reconstructions with free vascularized fibula associate difficulties for a simultaneous restoration of the alveolar height and facial contour, which are derived from the height discrepancy between the fibula and the native mandible. In addition, the donor-site growth and morbidity are of special concern in the pediatric patient...

Ectopic molars within the mandibular ramus/condyle unit, although rare, present a unique challenge to the surgeon. Multiple approaches have been described in the literature for their removal. A review of the English literature on the subject of mandibular ectopic molars and their epidemiology, etiology, indications for removal, and surgical techniques was completed. In addition, a case report is presented of an ectopic mandibular molar in the mid-ramus region which was removed via a minimally invasive, intraoral, technique combining the use of endoscopy and piezoelectric surgery...

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...

Chondroma is a benign cartilaginous tumor composed of mature hyaline cartilage and represents only 2.38% of all osteocartilaginous tumors; cases that arise in the preauricular region are rarely found in the literature. This article presents an 80-year-old man with preauricular swelling on the right side and pain with no limitation of joint motion. This patient was evaluated by preoperative clinical manifestation, fine needle aspiration, ultrasound, and magnetic resonance imaging (MRI) scans. The MRI shows a solid lobulated lesion between the masseter muscle and the parotid gland whereas fine-needle aspiration did not provide a diagnosis...

Mandibular fractures are rare, most commonly occurring in young male patients who present with facial trauma. The etiology, incidence, and presentation vary among previous publications depending on cultural and socioeconomic factors of the region of origin. This multi-institutional study aims to present demographic characteristics, surgical treatment, and clinical outcomes of surgical repair of mandible fractures in the United States. An analysis of the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) adult databases of the years 2006 through 2014 was performed identifying 940 patients with an International Classification of Diseases, version 9 (ICD-9) diagnosis of either closed or open fracture of the mandible...

Mandible fractures are the most common result of facial trauma. The proximity of oral flora to the site of both the injury and resulting surgical instrumentation makes managing infection a unique challenge. The benefit of antibiotic prophylaxis at the time of surgical treatment of mandible fractures is well established. However, the routine use of antibiotics between the time of injury and surgery is of unclear benefit. We aim to define the role of antibiotics in the preoperative period: from the time of injury to surgical intervention...

Iatrogenic injuries to cranial nerves, half of which affect the hypoglossal nerve, occur in up to 20% of surgical procedures involving the neck. The risk of injury could be minimized by in-depth knowledge of its positional and relational anatomy. Forty-one hypoglossal nerves were dissected from cadaveric specimens and positions described in relation to the internal carotid artery (ICA), external carotid artery (ECA), carotid bifurcation, mandible, hyoid bone, mastoid process, and the digastric tendon. The distance of the nerve from where it crossed the ICA and ECA to the carotid bifurcation was 29...

Examination of the mental state of patients suffering from facial trauma is rarely ever recorded, let alone screening them for posttraumatic stress disorders (PTSDs) or generalized anxiety disorder. Providing early support to the patient in light of such psychological conditions can improve the overall quality of life. The aim of this study was to perform a literature review to assess the relation of mental state disorders to facial trauma in terms of their prevalence, assess screening methodology, and also to evaluate the prognosis of individuals subjected to psychological intervention/screening at an early stage of clinical examination...

Reconstruction of the head and neck can be a challenging undertaking owing to numerous considerations for successful rehabilitation. Although head and neck defects were once considered irretrievably morbid and associated with a poor quality of life, advances in surgical technique has immensely contributed to the well-being of these patients. However, all patients are not suitable surgical candidates and many have sought nonsurgical options for functional and cosmetic restoration. As such, the advent of prostheses has ameliorated those concerns and provided a viable alternative for select patient populations...

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...
