The aim of this study was to evaluate the stability of Le Fort I maxillary
inferior repositioning surgery in patients with a vertical maxillary deficiency
at least 6 months after surgery. The electronic databases were searched to
identify all articles reporting the long-term effects of one-piece maxillary
inferior repositioning with rigid fixation. Methodological quality was evaluated
according to 15 criteria related to study design, measurements, and statistical
analysis. Two articles were identified, with a total of 22 patients. The maxilla
was repositioned inferiorly from a mean 3.2 to 4.5mm in the anterior part and
from a mean 0.1 to 1.8mm in the posterior part. At 6 months post-treatment,
absolute relapse of a mean 1.6mm was measured for the anterior part of the
maxilla and 0.3mm for the posterior part of the maxilla. The stability of
maxillary inferior repositioning surgery could not be confirmed due to the small
sample size, unclear diagnosis, and potential confounding factors.
