Use of the Iliac Crest Cortex for Premaxilla Fixation in Patients With Bilateral Clefts.

The aim of the present study was to evaluate the effectiveness of fixation of the premaxilla to the remaining maxillary stumps using the iliac crest cortical bone and screws in 16 patients with bilateral alveolar clefts. The technique was used in patients who required surgical repositioning of the premaxilla owing to its severe anterior projection and mispositioning. Postoperative follow-up was performed using periapical and occlusal radiographs and clinical examinations at 3 and 6 months after surgery. Subsequently, the patients were referred for resumption of orthodontic treatment. Of the 16 patients evaluated, only 1 patient experienced unilateral loss of the graft, requiring further surgical intervention.

Temporal Flap as an Option for Buconasal Fistula Closure.

Maxillary defects with buconasal/businusal communications are situations difficult to manage and solve. Several treatment options are available on the literature, each one with its indication. Temporal muscle flap is one of these options, being a technique that requires more experience of the surgeon to be properly performed and that is mainly indicated for difficult cases, large defects and those nonresponsive to simpler techniques. The main purpose of this paper is to report 3 clinical patients of the application of the temporal muscle flap for the closure of extensive oral defects. None of the patients had necrosis, nervous deficits, or any long-term changes. The authors conclude that the use of this flap was shown to be a viable, safe technique with low complication and high success rates, which may contribute to the rehabilitation of well-indicated patients.

Pedicle Tongue Flap for Palatal Fistula Closure.

BACKGROUND: Palatal fistulae are common sequels that appear in patients after surgical procedures in the palate. Considering the difficulty to achieve an effective treatment, there are many techniques to surgically manage fistulae, that is, the pedicle tongue flap. OBJECTIVE: Being so, the main goal of this paper is to report cases of patients with palatal fistulae, from different etiologies, treated with anterior pedicle tongue flap. PATIENTS: Eleven patients, 8 male and 3 female, mean age of 32 years old with palatal fistulae surgically treated with anterior dorsal tongue flaps. No flap was completely lost. There was 1 partial loss and 1 residual buconasal communication. The most common complaints of the patients were difficulty to perform oral hygiene and mild pain. CONCLUSION: The use of anterior pedicle tongue flap for closing palatal fistulae demonstrates to be a safe procedure with high success rates (81% in this paper) when correctly indicated.

Tratamento cirúrgico de fratura de seio frontal: relato de caso clínico / Surgical treatment of frontal sinus fracture: case report

As fraturas do seio frontal ocorrem em casos de impactos de alta intensidade e causam divergência quanto a sua prevalência. Geralmente, estão associadas com fraturas da região naso-órbito-etmoidal, porém podem ocorrer isoladamente. Suas conseqüências funcionais podem ser graves, caso exista a obliteração do ducto fronto-nasal e, esteticamente, a seqüela restante geralmente causa grande constrangimento para o paciente. O presente artigo relata um caso de fratura de seio frontal com redução cirúrgica após 12 dias, suas implicações funcionais, estéticas e sociais. A técnica pela qual o paciente optou após explanações sobre vantagens e desvantagens de diferentes métodos cirúrgicos foi a cirurgia de redução da fratura cominutiva com acesso coronal, fixação com placas e parafusos de titânio e proservação ambulatorial. Imediatamente após o término da cirurgia, notou-se uma sensível melhora no contorno da fronte e imobilidade dos cotos ósseos. Após 60 dias (com acompanhamento anterior aos 7, 21 e 30 dias), o paciente mostrou plena satisfação com a estética local, não relatou nenhum episódio de algia ou desconforto, tendo voltado ao trabalho e ao convívio social sem dificuldades relatadas

The frontal sinus fractures occurs in cases of high-intensity impacts and cause disagreement as to its prevalence. Usually are associated with fractures of the naso-orbit-ethmoid region, but can occur in isolation. Their functional consequences could be serious if there is obliteration of the fronto-nasal duct, and aesthetically, the sequel rest usually causes great embarrasment for the patient. This article presents a case of frontal sinus fracture with surgical reduction after 12 days, its functional, aesthetic and social implications. The technique by which the patient chose after explanations about advantages and disadvantages of different surgical methods of surgery was reduced with access coronal comminuted fracture, fixation with titanium plates and screws and proservation outpatients. Immediately after surgery we noted a significant improvement in the contour of the forehead and immobility of the bone stumps. After 60 days (up to previous 7, 21 and 30 days), the patient showed full satisfaction with the aestheticsof the site, reported no episode of algia or discomfort, and returned to work and social life without difficulties reported

Surgical repositioning of the premaxilla with bone graft in 50 bilateral cleft lip and palate patients.

PURPOSE: The aim of this study was to evaluate a modified surgical technique for premaxilla repositioning with concomitant autogenous bone grafting in bilateral trans-foramen cleft lip and palate patients. PATIENTS AND METHODS: The study included 50 bilateral trans-foramen cleft lip and palate patients. Bone graft was harvested from the mandibular symphysis in 24 patients. Whenever more grafting was necessary, the iliac crest bone was used as the donor site (26 patients). The premaxilla was displaced by rupturing the bone and the palatine mucosa, and repositioned in a more adequate position using a surgical guide. The premaxilla and the grafts were fixed with miniplates and screws or screws only. The surgical guide was kept in place for 2 months, whereas the miniplates and screws were removed after 6 months, together with the complete bilateral lip and nose repair. Follow-up examinations were performed at 3, 6, and 12 months by means of periapical and occlusal radiographs, and by clinical examination. Thereafter, the patients were referred for completion of the orthodontic treatment. RESULTS: Overall, in 48 cases (96%) the treatment achieved total graft integration, with complete closure of the bucconasal and palatal fistulas, and premaxilla stability (either at first surgery or after reoperation). In the remaining 2 patients (4%), the treatment failed, due to necrosis of the premaxilla. CONCLUSIONS: The procedure is complex and involves risk. However, the patient's social inclusion, especially at the addressed age group, is the best benefit achieved.

Use of allogeneic bone graft in maxillary reconstruction for installation of dental implants.

The aim of this study is to evaluate the efficacy of the application of allogenous bone at the maxillomandibular reconstructions for future rehabilitation with dental implants. The patients were submitted to reconstruction of maxilla, using allogeneic bone grafts, in 3 different techniques: onlay grafts for lateral ridge augmentation, onlay and particulate bone for sinus lift grafting, and particulate alone for sinus lift grafts. Clinical and radiographic control was done at the postoperative phase for at least 8 months, until the patient could be submitted to the installation of dental implants. The results showed success in the majority of the cases, and dental implants could be installed. This can be considered an excellent alternative when compared with the use of autogenous grafts; because handling is easier, there is a great amount of material available and a possibility of using local anesthesia, and consequently there is a reduction of patient morbidity.

Correção das deficiências transversas e ântero-posteriores da maxila em pacientes adultos / Maxillary anteroposterior and transverse problems correction in adult patients

OBJETIVO: a finalidade deste trabalho é avaliar os resultados de tratamento de pacientes com desarmonias esqueléticas Classe III e discrepâncias transversas, tratados com a técnica de expansão maxilar assistida cirurgicamente, associada à mecânica de tração reversa. METODOLOGIA: Foram avaliados 10 pacientes portadores de Classe III esquelética e discrepância transversal, submetidos à expansão maxilar assistida cirurgicamente e ao uso de máscara facial. A avaliação das alterações ortodônticas e ortopédicas foram realizadas por meio dos exames clínico e radiográfico. CONCLUSÃO: os resultados clínicos e radiográficos demonstraram eficiência nestes procedimentos, evitando nova cirurgia de maxila, diminuindo a morbidade do tratamento e o seu custo.

AIM: The purpose of this article is to evaluate the correction of anteroposterior and transverse maxillary deficiency in adult patients with the use of facial mask and surgically assisted RME (SARME). METHODS: Reverse traction of the maxilla was applied to 10 subjects through a facial mask after a SARME. All individuals presented a Class III skeletal malocclusion. Cephalometric tracings were used to access the amount of anterior maxillary displacement during treatment. RESULTS AND CONCLUSION: The association of these procedures promoted transverse correction and anterior displacement of the maxilla. This approach avoided a two step correction - one for SARME and other for maxillary advancement, reducing morbidity and costs of treatment.
