RESUMO
The presence of a large palatal or maxillary defect after partial or total maxillectomy for tumor, trauma or congenital deformation poses a challenge to prosthodontists, particularly when the use of an implant cannot be considered. This case report described the use of an air valve in a hollow silicone obturator to manufacture an inflatable obturator that could be extended further into undercut area to retain itself. The inflatable obturator exhibited adequate retention, stability and border sealing, thereby improving the masticatory,pronunciation and swallowing functions of patients. It may be a suitable alternative treatment option to an implant-retained obturator.

This study evaluated the aesthetic and functional outcomes of vascularized fibular flaps used for pediatric mandibular reconstruction. Six pediatric patients ranging in age from 12 to 15 years underwent mandibular reconstruction using a vascularized fibula flap with a skin paddle, after benign tumor ablation. All of the flap transfers were successful, and there were no complications. Panorex radiographs showed good bone union in all patients. The flap conferred adequate support for dental rehabilitation. The mean follow-up was 24.2 months. The aesthetic and functional outcomes were normal. No patient had recurrence. A vascularized fibular flap is a very reliable method for reconstructing the pediatric mandible after benign tumor ablation.

Treatment options of maxillary fibrous dysplasia are surgical recontouring or total or partial maxillectomy depending on the site and behavior of the lesion. Among the reconstruction procedures, which include many surgical options, reconstruction using a maxillary obturator is the least invasive one. This report describes a case of aggressive maxillary fibrous dysplasia that was treated with a total maxillectomy and reconstructed with a malar implant-retained maxillary obturator.

Focal fibrocartilaginous dysplasia is a rare benign entity, previously described as a factor responsible for causing tibia vara at the walking age. We report here the case of a child with tibia valga due to focal fibrocartilaginous dysplasia of the lateral part of the proximal tibia. To our knowledge, this is the first observation of a lesion located in the lateral proximal tibia. Clinical, radiographic and magnetic resonance imaging surveillance was performed. Spontaneous resolution of the lesion with correction of the angular deformity did occur.
