Active clinical trials for "Micrognathism"

The present study aims to compare ethmoid, sphenoid and maxillary sinus volumes of patients with maxillary deficiency requiring Le Fort osteotomy with healthy patients, by employing computed tomography imaging. No accessible information could be found on this subject during literature search. The authors believe anatomical knowledge of these structures in patients with maxillary deficiency will influence all branches performing surgeries in these areas.

The goal of this study is to evaluate whether the use of a bone graft substitute at the osteotomy site will result in better stability and diminish early relapse after mandibular lengthening surgery. The study focuses on the evaluation of the following hypothesis: The use of bone graft substitute at the osteotomy site has an influence on: The 3-dimensional stability of the osteotomy site Early relapse based in the plasticity of the site

This study investigates the relationship of circulating microRNA-30e and schizophrenia, and shows the relevance of the aberrant microRNA-30e expression in plasma with the variation disease status.
