RESUMO

Orbital fractures alone represent 10% up to 25% of all facial fractures, but when they are associated with other fractures of the middle-third of the face, their incidence can increase up to 55%. This study aimed to identify whether the size of the orbital defect based on the classification by Jaquiéry et al. influenced the resolution of post-traumatic complications after orbital wall reconstruction using PRECLUDE®MVP alone or in combination with a titanium mesh or autogenous bone graft. Thirty-five orbits were categorized into four groups on the basis of the size of the defect and the operative techniques: group 1 contained 16 Jaquiéry class I orbits treated only with PRECLUDE®MVP; group 2 included eight class II orbits treated with PRECLUDE®MVP along with autogenous bone graft harvested from the calvaria or a titanium mesh; group 3 included five class III orbits and group 4 included six class IV orbits that were treated the same way as those in group 2. Spearman correlation showed that the use PRECLUDE®MVP didn't improve the post traumatic complications for big orbital defects due to the three-dimensional anatomical changes that occurred by neurologic lesions and lipolysis of the orbital contents.

RESUMO

O hemangioma é uma lesão vascular, podendo represen-tar-se como uma neoplasia benigna dos vasos sanguíneos, relativamente rara na cavidade oral, podendo causar prejuízo estético e funcional a depender da sua região. Sua localiza-ção mais frequente é o lábio superior, mas pode ocorrer em outras regiões, como língua, mucosa jugal e palato. O seu tratamento depende, principalmente, do correto diagnóstico da lesão, bem como da localização anatômica da mesma e pode ser realizado com esclerose química, crioterapia, la-serterapia, excisão cirúrgica convencional, embolia arterial ou eletrocautério. O objetivo desse trabalho é apresentar um caso clínico, de um paciente do gênero masculino, 63 anos de idade, apresentando hemangioma desde os 16 anos de idade, com recidiva há dez anos em lábio superior. Ao exame físico intrabucal observou-se uma lesão tumoral, de coloração arroxeada, base séssil, assintomática, com limites bem definidos, medindo aproximadamente 4 cm em seu maior diâmetro, localizada na mucosa labial superior. Foi realizada manobra de vitropressão que apresentou um esmaecimento da coloração arroxeada, permitindo diag-nóstico clínico de hemangioma. O tratamento proposto foi a esclerose terapêutica com cinco aplicações de oleato de monoetanolamina 5%, considerando as características clínicas e os métodos de diagnóstico desta lesão. Por meio de um diagnóstico preciso e uma conduta terapêutica ade-quada, o caso apresenta-se com um acompanhamento de dois meses com significativa redução até o momento, e com um resultado estético funcional satisfatório. Conclui-se que a eficácia da escleroterapia realizada com o uso do oleato de monoetanolamina 5% é uma alternativa terapêutica segura.

Hemangioma is a vascular lesion, and may represent a benign neoplasm of blood vessels, relatively rare in the oral cavity, and may cause aesthetic and functional impairment depending on its region. Its most frequent location is the upper lip, but may occur in other regions, such as tongue, jugal mucosa and palate. Its treatment depends mainly on the correct diagnosis of the lesion, as well as its anatomical location and can be performed with chemical sclerosis, cryotherapy, laser therapy, conventional surgical excision, arterial embolism or electrocautery. The aim of this paper is to present a case report of a 63-year-old male patient with hemangioma since he was 16 years old, with a recurrence of the upper lip for 10 years. Physical examination revealed an asymptomatic purplish-colored, lesion-shaped tumor with well-defined limits, measuring approximately 4 cm in its largest diameter, located in the upper lip mucosa. A vitropression maneuver was performed that showed a faint purplish coloration, allowing a clinical diagnosis of hemangioma. The proposed treatment was therapeutic sclerosis with five applications of 5% mono-ethanolamine oleate, considering the clinical characteristics and diagnostic methods of this lesion. Through an accurate diagnosis and an appropriate therapeutic approach, the case presents a two-month follow-up with significant reduction so far, and a satisfactory functional aesthetic result. It is concluded that the effectiveness of sclerotherapy perfor-med with the use of 5% monoethanolamine oleate is a safe therapeutic alternative.

RESUMO

Nowadays the reconstruction of craniofacial defects can be performed with different kinds of materials, which include the bone and the so-called biomaterials, which have the advantage of not needing a surgical site donor. Among these materials, great attention is given to polymers. In this large group, current attention is focused on the castor oil polymer, since this polymer is biocompatible, low cost, and has adequate strength for reconstruction of the craniomaxillofacial complex. This study aims to report the use of a prosthetic castor oil polymer for reconstruction of extensive defect, caused by a trauma, in the temporoparietal region.

RESUMO

The carotid-cavernous fistula (CCF) is a rare complication in patients victimized by craniofacial trauma. It involves multidisciplinary medical action. Owing to its potential complications, it is essential that maxillofacial surgery and neurosurgery specialists diagnose this condition so that appropriate treatment can be performed. The authors present a report of a case 11 years after the surgery.

RESUMO

A descoberta dos bisfosfonatos (BFs) como fármacos relacionados à inibição da reabsorção óssea os consagrou para o tratamento de pacientes portadores de osteoporose e de neoplasias com metástases ósseas, o que culminou com o seu uso ampliado. O presente trabalho tem por objetivo expor a importância da identificação dos pacientes que fazem uso dos BFs contribuindo assim para o adequado conhecimento sobre os riscos de complicações que acometem esses pacientes. O trabalho enfoca o emprego clínico dos BFs, os riscos que representam para os ossos da face, consideradas as suas características, bem como a importância de diagnosticar pacientes que fazem uso desses fármacos, a fim de orientá-los sobre o adequado tratamento odontológico a ser realizado, e desta forma contribuir para a redução da complicação que tem evolução imprevisível e consequências devastadoras para os pacientes.

The bisphosphonates (BFs) as a drug-related inhibition of bone resorption consecrates its to the treatment of patients with osteoporosis and cancer with bone metastases, which culminated with its expanded use. This study aims to explain the importance of identifying patients who make use of BFs thereby contributing to the adequate knowledge on risks related to these complications affecting patients. This study focuses on the clinical use of BFs, the risks it represents to the facial bones, considered its characteristics as well as the importance of diagnosing patients who use these drugs, in order to conduct them on the proper dental treatment to be held initially, and thus, to contribute to the reduction of complication that means an unforeseeable and devastating consequences for the patients.
