ABSTRACT
BACKGROUND:
Postoperative periorbital edema and ecchymosis after rhinoplasty are mainly caused by the osteotomy with hammer and chisel. The introduction of piezoelectric surgery could lead to a better early postoperative outcome due to improved preservation of soft tissues. The aim of this systematic review was to evaluate the methods and results of studies comparing conventional osteotomy to piezoelectric osteotomy.METHODS:
A systematic literature search was conducted in the PubMed/MEDLINE and Google Scholar databases. In the primary selection, all studies on the comparison of conventional and piezoelectric osteotomies with regard to postoperative periorbital edema and/or ecchymosis were identified. Secondary selection included only study designs with a control group.RESULTS:
Primary selection resulted in 15 thematically relevant publications with a notable increase in annual publications between 2007 and 2017. Six studies with control groups were selected secondarily. Qualitatively and methodologically, the studies were very heterogeneous. The results of five of the six studies indicated a significant advantage of piezo technology compared to conventional osteotomy. Only in one study was no significant difference found in the investigated postoperative outcome.CONCLUSION:
Piezoelectric osteotomy resulted in a reduced propensity for postoperative edema and ecchymosis compared to the conventional osteotomy technique with a chisel. At this time, the results should be regarded as a trend. A definite recommendation favoring piezoelectric osteotomy cannot be made until more studies with higher patient numbers become available.Palabras clave
