INTRODUCTION Trauma caused by traffic accidents is among the main etiologies involved in the occurrence of facial fractures throughout the world. However, the trauma mechanisms involved are different according to the location where the study was performed, due to different conditions of development, legislation, and culture. A retrospective study was done between February 2001 and July 2006, with the purpose of determining the epidemiology and the mechanisms involved in the occurrence of facial fractures among car occupants in the metropolitan area of São Paulo. METHODS Data were collected from 297 patients admitted with facial fractures to the emergency room of the Hospital das Clínicas, São Paulo University Medical School. Within this period, 151 individuals had been involved in traffic accidents, among which 56 (37.08%) were inside passenger cars. These were grouped based on the seating position that they were occupying at the time of the accident and the wearing of seat belts. Data concerning the number and location of fracture lines were obtained from the different groups, and a fracture/patient index (F/P I) was calculated to compare and make reference to the impact energy among these groups, for subsequent analysis and discussion. RESULTS 323 fracture lines occurred among 56 patients who were car occupants. By applying the F/P I, we obtained higher values in the group of rear-seat passengers who were not wearing seat belts (7.23 fractures per patient), followed by the group of drivers not wearing seat belts (6.33 fractures per patient), the group of front-seat passengers not wearing seat belts (5.58 fractures per patient), the group of drivers wearing seat belts (5.54 fractures per patient) and, finally, the group of front-seat passengers wearing seat belts (4.00 fractures per patient). None of the rear-seat passengers was wearing seat belts. CONCLUSION The data collected indicate that the driver position shows a high incidence of facial fractures, not being effectively protected by the seat belt, although the wearing of seat belts seems to have a protective role against the occurrence of facial fractures in front-seat passengers. It was not possible to evaluate the wearing of seat belts among rear-seat passengers, even though the high incidence of fractures in this group showed its high susceptibility to the occurrence of facial fractures, which highlights the need of taking protective measures against this situation.

Telecanthus, the lateral displacement of the medial canthus, can be a congenital deformity or can occur after facial trauma or tumor resection. Treatment of telecanthus remains a challenge for plastic surgeons. For proper correction, it is necessary to shift the medial canthus medially, fixing its tendon to the bone. The ideal technique would allow easy, safe, and stable fixation of the tendon, permit a unilateral approach with minimal incisions, and be cost-effective. The purpose of this study was to evaluate the feasibility and results (immediate and long-term) of medial telecanthus repair using ipsilateral titanium microanchor fixation. Nine patients, 7 with unilateral telecanthus and 2 with bilateral telecanthus, underwent ipsilateral canthopexy involving a microanchor device. Anthropometric measurements of the orbital regions were taken before, immediately after, and at 1 year after surgery. Data for the affected sides were compared with those for the unaffected sides, and the evolution of those values was assessed throughout the 1-year follow-up period. For all patients, the final values were lower than those initially obtained. At 1 year after surgery, the intercanthal distance was reduced to age-adjusted normal values in all cases. On the operated side, stable improvement was observed in terms of the distance from the medial canthus to the midline, although some degree of recurrence was noted in most of the patients. The use of a microanchor system for medial canthopexy can be considered an easily performed and effective option for treating canthal dystopia, especially when an ipsilateral approach is preferred.

Pedro Ribeiro Soares de Ladeira; Endrigo Oliveira Bastos; Jaqueline Vaz Vanini; Nivaldo Alonso

Three-dimensional digital models of the face were developed to circumvent the limitations of the traditional assessment of soft tissue. Currently, a method reported to have a high clinical applicability is digital stereophotogrammetry. This systematic review aims to address the use of this technique in evaluating craniofacial abnormalities, with a focus on its practical application. The subject was searched in the Medline, Cochrane Library, LILACS, and SciELO databases. From preestablished inclusion criteria, 19 articles were selected. The data extracted were as follows: systems used, year of publication, diseases addressed, reference points used for each disease, advantages and disadvantages of the stereophotogrammetry system used, and quality of articles. The 3dMD® system was used in 11 articles. The most common publication year was 2010, with 6 studies. Twelve studies addressed cleft lip and palate, and 17 studies used anthropometric landmarks. Noninvasiveness, fast image acquisition, and accuracy were the advantages mentioned in 70% of the articles that used the 3dMD® system. The most frequently mentioned disadvantage of such equipment was the high cost. Twelve items had good level of scientific evidence. Digital stereophotogrammetry is a technology aimed to improve the evaluation of treatments and quantification of craniofacial deformities. However, there is a need for more studies with long-term monitoring and on the association of a wider variety of systems.

Pseudoaneurysm of the internal maxillary artery: A case report of facial trauma and recurrent bleeding

Nivaldo Alonso; Endrigo Oliveira Bastos; Benjamin B. Massenburg

INTRODUCTION Pseudoaneurysms occur when there is a partial disruption in the wall of a blood vessel, causing a hematoma that is either contained by the vessel adventitia or the perivascular soft tissue. PRESENTATION OF CASE A 32-year-old male presented to the emergency department presented with comminuted fractures in the left zygoma, ethmoids, and the right ramus of the mandible following a gunshot wound. The patient underwent open reduction of his fractures and the patient was discharged on the eighth day after the trauma. Thirteen days after the discharge and 21 days after the gunshot wound, the patient returned to the ER due to heavy nasopharyngeal bleeding that compromised the patency of the patients airways and caused hemodynamic instability. Arteriography of the facial blood vessels revealed a pseudoaneurysm of the maxillary artery. Endovascular embolization with a synthetic embolic agent resulted in adequate hemostasis, and nine days after embolization the patient was discharged. DISCUSSION The diagnosis of pseudoaneurysm is suggested by history and physical examination, and confirmed by one of several imaging methods, such as CT scan with contrast. Progressive enlargement of the lesion may lead to several complications, including rupture of the aneurysm and hemorrhage, compression of adjacent nerves, or release of embolic thrombi. CONCLUSION This case reports the long-term follow up and natural history of a patient with a post-traumatic pseudoaneurysm of the internal maxillary artery and the successful use of endovascular embolization to treat the lesion.

Background: Soccer is the most popular sport in Brazil and a high incidence of related trauma is reported. Maxillofacial trauma can be quite common, sometimes requiring prolonged hospitalization and invasive procedures. To characterize soccer-related facial fractures needing surgery in 2 major Brazilian Centers. Methods: A retrospective review of trauma medical records from the Plastic Surgery Divisions at the Universidade Federal de São Paulo–Escola Paulista de Medicina and the Hospital das Clinicas–Universidade de São Paulo was carried out to identify patients who underwent invasive surgical procedures due to acute soccer-related facial fractures. Data points reviewed included gender, date of injury, type of fracture, date of surgery, and procedure performed. Results: A total of 45 patients (31 from Escola Paulista de Medicina and 14 from Universidade de São Paulo) underwent surgical procedures to address facial fractures between March 2000 and September 2013. Forty-four patients were men, and mean age was 28 years. The fracture patterns seen were nasal bones (16 patients, 35%), orbitozygomatic (16 patients, 35%), mandibular (7 patients, 16%), orbital (6 patients, 13%), frontal (1 patient, 2%), and naso-orbito-ethmoid (1 patient, 2%). Mechanisms of injury included collisions with another player (n = 39) and being struck by the ball (n = 6). Conclusions: Although it is less common than orthopedic injuries, soccer players do sustain maxillofacial trauma. Knowledge of its frequency is important to first responders, nurses, and physicians who have initial contact with patients. Missed diagnosis or delayed treatment can lead to facial deformities and functional problems in the physiological actions of breathing, vision, and chewing.

BACKGROUND: Craniofacial surgery has overcome many challenges since its initiation into clinical practice. Several technical issues have been addressed and the basic infrastructure of the specialty has now been developed. At present, 25 years after the first publications on frontofacial advancement, questions still remain as to the appropriate age for surgery and the appropriate type of surgery that should be performed. The aim of this study was to evaluate patients surgically treated for syndromic craniosynostosis over the last 10 years at our institution. METHODS: All syndromic patients who underwent monobloc frontofacial advancement or only isolated facial advancement from 2001 to 2011were selected. Out of 70 patients in total, 56 underwent monobloc frontofacial advancement and 14 underwent facial advancement after fronto-orbital remodeling. All data concerning these patients were correlated with patient age and final result. Moreover, age at surgery, complications, and final results were correlated with the main preexisting problems. RESULTS: Final results for syndromic patients varied, depending on the syndrome and the age at which the procedure was performed. Monobloc frontofacial advancements had a low index of immediate postoperative complications, but there was a clear need for further procedures at the time of final facial growth. The index of positive outcome was higher in patients who underwent surgery at an older age. CONCLUSIONS: In cases of severe craniosynostosis with functional problems, monobloc frontofacial advancement is still the best therapeutic option.

Orthodontic Treatment of Patients with Orofacial Cleft

Paulo Roberto Pelucio Camara; Endrigo Oliveira Bastos; Daniel Souza Curi; Nivaldo Alonso

Cleft lip and cleft palate are major public health problems that should receive a comprehensive treatment (Freitas et al. 2012). These defects arise on intrauterine development of the face and may have long-standing implications on dental arch morphology and impair facial growth as well. Cleft correction itself may also harm facial growth potential, even if performed properly (Molsted et al. 2005). Anatomical and physiological cleft-related problems can have implications on speech, eating, and aesthetic, sometimes leading to deep psychological consequences. Proper dental care from birth to adulthood is necessary to overcome these conditions while avoiding further harm. In this setting, the orthodontist plays an important role in the prevention, correction, and reduction of the consequences of cleft lip and cleft palate (Long et al. 2000).

OBJECTIVES: To characterize the oral motor system of adults with facial injuries and to compare the oral motor performance/function between two different groups. METHODS: An observational, descriptive, cross-sectional study was conducted in 38 patients presenting with facial trauma who were assigned to the Division of Orofacial Myology of a Brazilian School Hospital. Patients were divided into two groups: Group 1 (G1) consisted of 19 patients who were submitted to open reduction of at least one facial fracture, and Group 2 (G2) consisted of 19 individuals who were submitted to closed fracture reduction with maxillomandibular fixation. For comparison purposes, a group of 19 healthy volunteers was recruited. All participants underwent a clinical assessment that included an oral motor evaluation, assessment of the mandibular range of motions, and electromyographic assessment of the masticatory muscles. RESULTS: Clinical assessment of the oral motor organs indicated that G1 and G2 presented deficits related to the posture, position, and mobility of the oral motor organs. Patients also presented limited mandibular ranges of movement. Deficits were greater for individuals in G1, especially for maximal incisor opening. Additionally, patients in G1 and G2 presented a similar electromyographic profile of the masticatory muscles (i.e., patients with facial fractures presented lower overall muscle activity and significant asymmetrical activity of the masseter muscle during maximum voluntary teeth clenching). CONCLUSION: Patients in G1 and G2 presented similar functional deficits after fracture treatment. The severity of facial fractures did not influence muscle function/performance 4 months after the correction of fractures.
