Effect of the menstrual cycle on intraoperative bleeding in rhinoplasty patients

Abstract

This study aimed to evaluate the effect of menstrual cycle phase on intraoperative bleeding in rhinoplasty patients. One hundred seven female patients grouped as G1 (perimenstrual) and G2 (periovulatory) according to menstrual cycle were included in this study. Intraoperative blood loss was compared using the t test. Fifty-two of the patients were in G1 and 49 were in G2 group. Operative surgeons, presence of additional interventions, and operation duration did not differ among the groups. Mean intraoperative blood loss was 69.0?±?24.6 ml in G1 and 80.4?±?27.7 ml in G2. The blood loss difference between the two groups was statistically significant. This study demonstrated that perioperative blood loss is higher in patients operated on during the periovulatory phase. This increase does not seem to create difficulty during the operation or to have an impact on the outcome. Nevertheless, this might be reflected in more pronounced ecchymosis in the early postoperative phase. © 2008 Springer-Verlag.
