Background: The aim of this study was to minimize edema and ecchymosis following rhinoplasty through a closed drainage system to address concealed hemorrhage.
Methods: This study was designed as a prospective، double blinded, randomized contr-olled study. Fifty one patients who underwent septorhinoplasty were included in this study and divided in two groups. In group A, a closed drainage system was applied in the most dependent posterior septal area following septal harvesting. Concealed bloody secretions were drained out of mouth in a vacutaner tube during three concecutive post operative days. In control group, group B, exactly the same classic rhinoplasty opera-tion by the same surgeon was done as for study group except omitting the closed drainage system. Degree of supra-tip and eyelid edema was evaluated on post operative days through photographic and software image analysis. Edema and ecchymosis rating of eyelids and ecchymosis of paranasal and cheek area done based on photographic analysis by independent plastic surgeons using a defined grading system.
Results: Eyelid ecchymosis was reduced significantly on post operative day 14 in the study group (P=0.03). Ecchymosis of paranasal and check was reduced considerably likewise on days 7 and 14 in group A using Mann-Whitney test (P=0.03). There was no significant deference regarding supra tip edema on post operative days. The same hold true for the eyelids edema.
Conclusion: Significant decrement observed in eyelids ecchymosis on day 14 and para-nasal and cheek ecchymosis on postoperative days 7 and 14 in study group. There were no positive effects regarding supra tip and eyelid edema reduction using closed drainage system to evacuate concealed haemorrhage in posterior septum space. There could be different etio-pathologies for two common morbidities following rhinoplasty that should be addressed separately.
