RESUMO
Atrophy of the alveolar ridge requires bone grafting at the implant site for rehabilitation of the masticatory function with dental implants. Despite the advances in the development of bone substitutes, autogenous bone graft remains the "criterion standard" because of its osteogenic, osteoinductive, osteoconductive potential, and non-immunogenic properties. However, harvesting of autogenous bone is not exempt from donor site morbidity. In this context, the use of autogenous bone derived from the proximal ulna might be a viable resource to obtain corticocancellous bone graft, as the harvesting from this donor site is associated with low morbidity. Thus, this article aimed to describe a case in which a maxillary sinus floor augmentation was performed by means of autogenous bone graft harvested from the proximal ulna, as the donor site. An appositional bone block graft harvested from the same region was used to augment the residual alveolar ridge. Clinically, healing proceeded uneventfully with no major complications. After 8 months, a proper amount of bone was found at the implant site, allowing a prosthetically driven implant insertion and subsequent implant-supported rehabilitation. Results were clinically and radiographically stable after a 3-year follow-up. The present case report suggested that proximal ulna as a donor site should be considered as a safe and reliable alternative for alveolar ridge augmentation. Besides the case presentation, a comprehensive review of the literature was also provided.

Surgical treatment of panfacial fractures usually requires intraoperative temporary occlusion of the teeth and simultaneous access to the nasal pyramid. In such cases, the standard method of airway management is to perform a tracheostomy, but this may be associated with a significant number of perioperative and late complications. This study aimed to determine if submental endotracheal intubation (SEI) is a viable alternative to tracheostomy, especially when short-term postoperative control of the airway is foreseen. This was an observational retrospective study, carried out between 2012 and 2014, which involved 32 consecutive patients who sustained panfacial fractures and were surgically treated during a 3-year period in a level I trauma center hospital. Only those who required SEI were included in the sample. Four cases were excluded because of incomplete registries, follow-up period less than 4 months after hospital discharge, or other unrelated complications. The medical charts of all patients involved in the sample were carefully reviewed in order to qualify and quantify perioperative and postoperative complications related to anesthetic management. We hypothesized that SEI would not interfere with the surgical procedures and would present less morbidity and reduced complication rates. Twenty-eight patients, 24 male and 4 female, met all the inclusion criteria. The mean age was 29.5 ± 9.05 years (range, 18-56 years). The mean duration time of surgery was 8.07 ± 4.0 hours (range, 4-16 hours). There were no perioperative complications. Postoperatively, only 1 patient (3.57%) experienced a cutaneous infection at the submental region, which was easily treated. Additionally, only 1 case (3.57%) of hypertrophic scar was reported. SEI appears to be a safe, simple, and effective technique of immediate perioperative airway management in selected cases of panfacial fractures.

Ameloblastoma is a relatively uncommon benign odontogenic tumor, which is locally aggressive and has a high tendency to recur, despite its benign histopathologic features. This pathology can be classified into 4 groups: unicystic, solid or multicystic, peripheral, and malignant. There are 3 variants of unicystic ameloblastoma, as luminal, intraluminal, and mural. Therefore, in mural ameloblastoma, the fibrous wall of the cyst is infiltrated with tumor nodules, and for this reason it is considered the most aggressive variant of unicystic ameloblastomas. Various treatment techniques for ameloblastomas have been proposed, which include decompression, enucleation/curettage, sclerotizing solution, cryosurgery, marginal resection, and aggressive resection. Literature shows treatment of this lesion continues to be a subject of intense interest and some controversy. Thus, the authors aimed to describe a case of a mural unicystic ameloblastoma of follicular subtype in a 19-year-old subject who was successfully treated using conservative approaches, as decompression. The patient has been followed up for 3 years, and has remained clinically and radiographically disease-free.

The ramus sagittal split osteotomy or mandibular body is an established technique for correction of dentofacial deformities but can have an accurate indication in cases requiring surgical access to remove lesions or more teeth included in the region of the mandibular angle. The main advantages of this technique are the possibility of preservation of the inferior alveolar nerve bundle and significant reduction in postoperative morbidity. In this article, the authors show a case in which the sagittal osteotomy of the mandible was used to gain access for removal of a lesion (complex odontoma).

Osteochondroma is a hamartomatous proliferation of cartilaginous tissue, which is the most common benign tumor of the long bones, but is relatively rare in the maxillofacial region. Most cases of mandibular condylar osteochondroma manifest with facial asymmetry or malocclusion with limited temporomandibular joint movements. Several approaches for management of this lesion have been proposed, as conservative condylectomy technique. This procedure has been suggested a valid approach to minimize facial asymmetry, contributing to the recovery of occlusion associated with no local tumor recurrence, and without condylar reconstruction procedure. Therefore, this article aims to describe a clinical report of a true osteochondroma of the mandibular condyle in a 35-year-old patient who was successfully treated using conservative condylectomy procedure.

PURPOSE: Cyanoacrylate has been used as a commercial tissue adhesive. Recently, ethyl 2-cyanoacrylate has been suggested for the fixation of onlay autogenous bone graft. However, ethyl 2-cyanoacrylate must be biocompatible with bone tissue. This study evaluated the cytotoxicity of cyanoacrylate adhesives using a direct contact assay on human oral osteoblast cells. MATERIALS AND METHODS: Osteoblastic cells derived from human alveolar bone of the mandible were cultured with or without cyanoacrylate. The CA1 group contained methyl 2-cyanoacrylate, the CA2 group contained ethyl 2-cyanoacrylate, and the CA3 group did not contain cyanoacrylate (control). This study investigated cell morphology, which included the inhibition zone, and cytotoxicity was evaluated using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, which was measured as optical density. Data from the MTT assay were tested statistically using SigmaStat 3.5. RESULTS: Dead cells found around the CA1- and CA2-treated cells constituted inhibitory zones that varied from 200 to 500 µm. There was no inhibitory zone in the CA3 group. Cell viability evaluated by the MTT assay showed that the CA2 and CA3 optical densities were not significantly different. The CA1 optical densities differed significantly from the CA3 optical densities. CONCLUSIONS: Within the limits of this study, the MTT method supported the conclusion that ethyl 2-cyanoacrylate is biocompatible according to a direct contact assay on human osteoblast cell cultures and suggests its usefulness in bone graft fixation.

Necrotizing fasciitis (NF) is an uncommon infection, but potentially lethal, especially when associated with systemic disorders such as diabetes. The authors report a case of necrotizing fasciitis from odontogenic origin in a patient with uncontrolled diabetes mellitus. The initial diagnosis was based on clinical information, in which multiple necrosis areas in cervical and thoracic regions were observed. Wide antibiotic therapy was applied, followed by surgical drain age and debridement. Culture was positive for methicillin-resistant Staphylococcus aureus. Although the treatment is established, the patient dies after sepsis and failure of vital organs. Clearly, the morbidity associated to this infection, even in diabetic patients, can be minimized if an early diagnosis and effective debridement are done.

Panfacial fractures usually refer to simultaneous facial fractures, which affect the upper, middle, and lower thirds of the face. The management of panfacial fracture is complex because of the lack of reliable landmarks. Literature has shown many approaches for management of panfacial fractures. Every segment of bone has a precise function in the repair. Therefore, the "bottom-up and outside-in" sequence is the most widely used approach in the management of panfacial fractures. These facial fractures present remarkable challenges for both experienced and inexperienced surgeons. This article aimed to report a case of a panfacial fracture (mandibular condylar and symphysis fractures associated with an atypical Le Fort III fracture) in a 48-year-old man. The patient was successfully treated using bottom-up and outside-in sequence by accessing all facial injuries. Postoperatively, radiograph examination revealed good reduction and fixation of titanium plates, and physical examination revealed good functional and esthetic outcomes.

Epidermoid cysts are rare benign tumors that are derived from the development of abnormally situated ectodermal tissue and are often an incidental finding. They are usually diagnosed between 15 and 50 years of age, with both sexes equally affected. In epidermoid cyst management, complete excision is the therapy of choice. The authors reported a case of a 24-year-old man with an epidermoid cyst located on the left side of the face, on the region of mandibular body, which was treated by complete surgical excision. The patient has been followed up for 2 years without signs of recurrence.

The orbit is an irregular conical cavity formed from 7 bones including the frontal, sphenoid, zygomatic, maxillary, ethmoid, lacrimal, and palatine bones. Fractures of the internal orbit can cause a number of problems, including diplopia, ocular muscle entrapment, and enophthalmos. Although muscle entrapment is relatively rare, diplopia and enophthalmos are relatively common sequelae of internal orbital fractures. Medial orbital wall fracture is relatively uncommon and represents a challenge for its anatomical reconstruction. In this context, autogenous bone graft has been the criterion standard to provide framework for facial skeleton and orbital walls. Therefore, it is possible to harvest grafts of varying size and contour, and the operation is performed through the bicoronal incision, which is the usual approach to major orbital reconstruction. Thus, this article aimed to describe a patient with a pure medial orbital wall fracture, and it was causing diplopia and enophthalmos. The orbital fracture was treated using autogenous bone graft from calvarial bone. The authors show a follow-up of 12 months, with facial symmetry and without diplopia and enophthalmos. In addition, a computed tomography scan shows excellent bone healing at the anterior and posterior parts of the medial orbital wall reconstruction.

Odontogenic abscess can become an orbital cellulitis, causing potentially serious intracranial and orbital complications. The full clinical complications from odontogenic orbital cellulitis in a pediatric patient are rarely seen daily in hospital emergency departments. Thus, odontogenic orbital cellulitis still remains a rarity, resulting in a medical challenge. With this in mind, this study aimed to describe a case of periorbital and orbital cellulitis resulting from odontogenic origin in a 6-year-old patient who was successfully treated by performing intravenous antibiotic administration combined with surgical drainage.

Among the many tissues in the human body, bone has been considered as a powerful marker for regeneration and its formation serves as a prototype model for tissue engineering based on morphogenesis. Therefore, collagen type I is one of the most useful biomaterials used in tissue engineering as extracellular matrix components capable to promote bone healing. The literature reveals excellent biocompatibility and safety due to its biological characteristics, such as biodegradability and weak antigenicity, making collagen type I the primary resource in medical applications. Thus, it was also used for tissue engineering including skin replacement, bone substitutes, and artificial blood vessels and valves. The authors describe the treatment of an abscessed apical periodontal cyst and show good outcomes of bone healing, using tissue engineering, as collagen type I matrix.

Osteochondroma is one of the most common benign tumors of the skeleton. This tumor is rare in the craniofacial region, with the most common sites of occurrence being the coronoid process of the mandible and the mandibular condyle. Traditionally, the treatments of these lesions include total condylectomy or local resection of the lesion. Conservative condylectomy procedure with reshaping of the remaining condylar neck and repositioning of the articular disk has been suggested. This article aimed to describe a 35-year-old woman with osteochondroma in the left mandibular condyle who was treated by conservative condylectomy. The patient has been free of recurrence for 2 years, showing good aesthetic and functional stability.

Inappropriate treatments of frontal sinus fractures may lead to serious complications, such as mucopyocele, meningitis, and brain abscess. Assessment of nasofrontal duct injury is crucial, and nasofrontal duct injury requires sinus obliteration, which is often accomplished by autogenous grafts such as fat, muscle, or bone. These avascular grafts have an increased risk of resorption and infection and donor site morbidity. For these reasons, pericranial flap, which is vascular, should be used for frontal sinus obliteration. The pericranial flap presented with less morbidity procedure and has decreased infection rates, which justifies its use in frontal sinus obliteration. This study aimed to report a case of a comminuted frontal sinus fracture with a brief literature review, regarding the use of pericranial flap. The authors report a case of a 23-year-old male subject with a severely comminuted fracture of the anterior and posterior walls of the frontal sinus. The patient was successfully treated by cranialization with frontal sinus duct obliteration, using anterior pericranial flap. The patient was followed up for 16 months with no postoperative complication, such as infection. Pericranial flap is a good resource for frontal sinus duct obliteration because it is a durable and well-vascularized flap, which determines low rates of postoperative complications.

Temporomandibular joint (TMJ) disorder is a term that encompasses a number of overlapping conditions, such as closed lock. Closed lock of the TMJ is considered a consequence of a nonreducing deformed disc acting as an obstacle to the sliding condylar head that usually causes a decrease in the maximum mouth opening and acute pain. The management of the TMJ is still controversial. Thus, arthrocentesis of the TMJ is a valuable modification of the traditional method of arthroscopic lavage, which consists of washing the joint in order to remove chemical inflammatory mediators and intra-articular adhesions, changing intra-articular pressure. TMJ disorder has always presented as a therapeutic challenge to maxillofacial surgeons. Therefore, this paper aimed to describe a clinical report of a closed lock of the left TMJ in a 19-year-old female subject who was successfully treated by arthrocentesis procedure.

Condylar hyperplasia is an overdevelopment of the condyle, which may manifest unilaterally or bilaterally. This pathological condition can lead to facial asymmetry, malocclusion, and dysfunction of the temporomandibular joint. The etiology and pathogenesis of condylar hyperplasia remain uncertain, but it has been suggested that its etiology may be associated with hormonal factors, trauma, and hereditary hypervascularity, affecting both genders. The diagnosis is made by clinical examination, and radiological imaging, and additionally, bone scintigraphy, is a fundamental resource for determining whether the affected condyle shows active growth. Patients with active condylar hyperplasia management have better results when they are subjected to the high condylectomy procedure. The authors report a case in a 20-year-old female subject with unilateral active condylar hyperplasia who was treated by high condylectomy. The patient has been followed up for 4 years without signs of recurrence and with good functional stability of the occlusion.

Fractures of the severely atrophic (<10 mm) edentulous mandible are not common, and these fractures with a vertical height of 10 mm or less have long been recognized as being particularly problematic. Although there are advances in the treatment of the atrophic mandibular fracture, the treatment remains controversial. There are some options for treatment planning because of using small miniplates to large reconstruction plates. However, when the fixation method fails, it causes malunion, nonunion, and/or infection, and sometimes it has been associated with large bone defects. The authors describe a clinical report of a failed miniplate fixation for atrophic mandibular fracture management. The authors used a load-bearing reconstruction plate combined with autogenous bone graft from iliac crest for this retreatment. The authors show a follow-up of 6 months, with union of the fracture line and no complication postoperatively.

PURPOSE: This study radiographically evaluated the performance of autologous platelet-rich plasma (PRP) applied in tooth sockets. PATIENTS AND METHODS: Thirty extractions of bilateral impacted mandibular third molars were performed in 15 volunteers (7 men, 8 women; 18 to 22 years old). After extraction of right and left mandibular third molars, the socket at 1 side received the autologous PRP (PRP group) and the other was filled with blood clot (control group). Millimeter periapical radiographs were obtained 7 days, 1 month, and 2, 3, and 6 months postoperatively. Radiographic bone density was quantified 3 times by the same examiner at different moments using HLImage 97 software, and data were statistically analyzed by Statgraf 7.0 software (analysis of variance and Tukey test). RESULTS: In general, there was significantly faster bone formation in sockets treated with PRP (P < .01). Significant bone formation was observed in the first month (P < .01), second month (P < .05), and third month (P < .01) for the PRP group. No statistical differences were observed on the seventh day and sixth month of investigation, yet there were higher means of radiographic bone density in sockets treated with PRP. In the control group, men exhibited significant bone repair compared with women (P < .05). CONCLUSION: Autologous PRP was found to accelerate alveolar bone regeneration, and men presented better repair after tooth extraction.

Fibrous dysplasia is a benign fibro-osseous disease that affects 1 or more bones. Deformities leading to aesthetic and functional disorders are observed in almost all cases. Plastic surgery is often recommended when the jaws are involved. Monostotic fibrous dysplasia of the mandible is an unusual manifestation of the disease that is usually benign, occurs in young individuals, and is managed by conservative curettage or debridement, such as surgical sculpting. The authors report a case of a 15-year-old patient with a large monostotic fibrous dysplasia located in the right mandible, which was treated by contouring bone. The lesion did not recur on follow-up for 4 years after the surgical procedure.

Modern techniques for surgical treatment of midfacial and panfacial fractures in maxillofacial trauma lead to special problems for airway management. Usually, in perioperative management of panfacial fractures, the surgeon needs to control the dental occlusion and nasal pyramid assessment. For these reasons, oral and nasal endotracheal intubations are contraindicated for the management of panfacial fractures. Tracheotomy is considered by many as the preferred route for airway management in patients with severe maxillofacial fractures, but there are often perioperative and postoperative complications concerning this technique. The submental route for endotracheal intubation has been proposed as an alternative to tracheotomy in the surgical management of patients with panfacial fractures, besides it is accompanied by low morbidity. Thus, this paper aimed to describe the submental endotracheal intubation technique in a patient experiencing panfacial fracture. The subject was well treated using the submental endotracheal intubation to get good reconstruction of the fractures because the authors obtained free access of all facial fractures.
