RESUMEN
This study explored the effects of L-PRF on pain, soft tissue healing, periodontal condition, and post-extraction bone repair of mandibular third molars (3Ms). A randomized, prospective, triple-blind, split-mouth clinical trial was conducted with 34 volunteers. Eligible patients were randomly allocated into two treatments: G1 (without L-PRF), G2 (alveoli filled with L-PRF), in which the removal of bilateral 3Ms was performed at the same surgical time. Outcomes were assessed according to a visual analogue scale (pain), soft tissue scoring system (wound healing), periodontal probing of mandibular second molar. Bone repair was determined by volumetric analysis (ITK-SNAP software) and fractal analysis (ImageJ software). An intention-to-treat approach to Statistical analysis was used. L-PRF reduced pain in the 7-day postoperative follow-up (p = 0.019) and not only improved soft tissue healing after 1 month of follow-up (p = 0.021), but also probing depth (distal face) in 3 months postoperatively (p = 0.011). Significant alveolar reduction occurred in 3 months after surgery in both treatments (p < 0.05), however, this was more significant in G1 (p = 0.016). The fractal dimension showed no statistical differences. L-PRF improved postoperative clinical parameters of pain, soft tissue healing, and periodontal condition, suggesting that it has a beneficial effect on preserving the alveolar ridge and accelerating the initial repair process.

O angiofibroma juvenil nasofaríngeo é um tumor benigno altamente vascularizado, de crescimento lento, mas localmente invasivo e destrutivo. De baixa prevalência, geralmente se localiza na nasofaringe de indivíduos jovens do gênero masculino. As características clínicas mais comuns são obstrução nasal e epistaxe. Possui diagnóstico baseado, principalmente, nos achados clínicos e imaginológicos, já que a biópsia é dificultada pelas características vasculares da lesão. Seu tratamento de escolha é a excisão cirúrgica, que pode ser realizada por diversas técnicas: via endoscópica, degloving médio-facial, via transpalatina, rinotomia lateral ou através da Osteotomia Le Fort I. O objetivo deste trabalho é relatar a utilização da Osteotomia Le Fort I como acesso para o tratamento cirúrgico de três pacientes do gênero masculino portadores de extensos angiofibromas localizados na nasofaringe que procuraram atendimento no ambulatório de cirurgia buco-maxilo facial do Hospital Universitário Presidente Dutra (HUUFMA)...

Juvenile nasopharyngeal angiofibroma is a slow-growing, highly invasive and vascularized benign tumor. With low prevalence rate, it is usually located in the nasopharynx of young men. The most common clinical characteristics are nasal obstruction and epistaxis. Its diagnosis is based mainly on the clinical and imaging findings, for the biopsy is hindered due to the vascular characteristics of the lesion. Thus, the treatment of choice is its surgical excision, which can be performed by many techniques: endoscopic, medial-facial degloving, transpalatine, lateral rhinotomy or through the Le Fort I Osteotomy. This paper aims to depict the use of Le Fort I Osteotomy approach for the surgical treatment of three male patients with extensive angiofibroma located in nasopharynx who sought care at the Oral and Maxillofacial Surgery Department of Presidente Dutra University Hospital....
