Introduction- After aesthetic surgery, one of the most common side effects is postoperative hematomas. Research with limited power and experiences from a single institution have hindered the ability to identify risk factors for hematopoiesis. The aim of present study was to assess the incidence and risk factors for major hematomas in aesthetic surgery. Material and methods- The present prospective study was conducted at a tertiary care centre among 500 patients who visited to department of plastic surgery for cosmetic procedure during the study period of one year. The study examined patient characteristics, risk factors, and hematoma rates among patients who underwent different combinations of procedures using SPSS version 25.0. Results- Presence of hematoma was found in 1% of patients while it was absent in 99% of cases. Overall, the mean age was 40.9 ± 13.8 years and the mean BMI was 24.6 ± 4.4 kg/m2. There were 180 male and 319 females. More complications were present in combined procedures (60%) as compared to single procedures (40%). Independent risk factors (P < 0.05) for postoperative hematomas after cosmetic procedures include: age, gender (male) , combined procedures, and breast procedures Conclusion - After cosmetic surgery, the most frequent complication is a major hematoma. Patients who are male and undergoing breast or combined operations are at a notably increased risk of hemorrhaging.
