Abstract

Background: The study aimed to investigate the risk factors that could affect intraoperative blood loss in patients who underwent orthognathic surgery.

Material and methods: The study included a retrospective analysis of 400 patients who underwent bimaxillary orthognathic surgery. Data on demographic, surgical, and hematological parameters affecting intraoperative blood loss were statistically analyzed.

Results: The mean intraoperative blood loss of male patients was statistically higher than that of female patients (p ≤ 0.001). The mean blood loss was higher in patients aged 25 years and older than in patients aged 17-24 (p=0.004). Patient weight and duration of surgery were positively correlated with the amount of intraoperative bleeding (r = 0.280 and r = 0.371). Platelet (PLT) count negatively correlated with blood loss (r=-0.213). The MPV/PLT ratio and hemoglobin (HGB) levels were positively correlated with bleeding (r=0.208 and r=0.110).

Conclusions: In orthognathic surgeries, factors such as age, gender, body mass, and duration of surgery were found to be associated with intraoperative blood loss. Males, patients over 24, overweight patients, and prolonged surgical procedures are all significant risk factors for bleeding. In addition, high HGB levels, low platelet count, and low MPV/PLT ratios are also associated with an increased risk of blood loss.

影响双颌正颌手术术中出血量的因素。

背景：本研究旨在探讨影响正颌手术患者术中出血量的危险因素。材料和方法：本研究包括对400例接受双颌正颌手术的患者进行回顾性分析。统计分析影响术中出血量的人口学、外科和血液学参数数据。结果：男性患者术中平均出血量明显高于女性患者（p≤0.001）。25岁及以上患者的平均失血量高于17-24岁患者（p=0.004）。患者体重、手术时间与术中出血量呈正相关（r = 0.280、r = 0.371）。血小板（PLT）计数与出血量呈负相关（r=-0.213）。MPV/PLT比值和血红蛋白（HGB）水平与出血呈正相关（r=0.208和r=0.110）。结论：在正颌手术中，年龄、性别、体重、手术时间等因素与术中出血量有关。男性、24岁以上患者、超重患者和手术时间延长都是出血的重要危险因素。此外，高HGB水平、低血小板计数和低MPV/PLT比率也与失血风险增加有关。
