Purpose: Perioperative hemorrhage is an important concern during orthognathic surgery. The purpose of this study was to assess the effect of tranexamic acid (TXA) irrigation on perioperative hemorrhage during orthognathic surgery.

Materials And Methods: In this double-blind, randomized controlled clinical trial, 56 participants who underwent orthognathic surgery were divided into 2 groups. The patients in the first group received TXA irrigation with normal saline (1 mg/mL), and the patients in the second group had normal saline for irrigation during orthognathic surgery. Age, gender, operation duration, the amount of irrigation solution used, and preoperative hemoglobin, hematocrit, and weight were the variables that were studied. The use of TXA solution for irrigation was the predictive factor of the study.

Results: Each group consisted of 28 patients. Group 1 consisted of 15 male patients (53.6%) and 13 female patients (46.4%) and group 2 consisted of 14 male patients (50%) and 14 female patients (50%). There was no difference in the distributions of the variables between the 2 groups, except for the duration of the operation. The mean duration of the operation was 3.94 ± 0.61 hours in group 1 and 4.17 ± 0.98 hours in group 2, and the difference in this respect between the 2 groups was statistically significant (P < .05). The mean intraoperative blood loss was 817.85 ± 261.83 mL in group 1 and 575.00 ± 286.90 mL in group 2 (P < .05). The mean volume of irrigation was 1,057.14 ± 407.04 mL in group 1 and 843.57 ± 275.48 mL in group 2 (P > .05).

Conclusions: TXA is effective in reducing intraoperative blood loss in patients for whom substantial blood loss is anticipated.

Ethnic rhinoplasty in Iranians: the oral and maxillofacial surgery experience.

J Oral Maxillofac Surg 2014 Dec 30;72(12):2568.e1-7. Epub 2014 Jul 30.

Associate Professor of Oral and Maxillofacial Surgery, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

Purpose: Rhinoplasty is a common esthetic procedure in Iran. The aim of the present study was to evaluate Iranian patient satisfaction. The role of ethnicity in surgical planning was assessed.

Materials And Methods: This cross-sectional study examined participants aged between 18 and 45 years who underwent primary rhinoplasty. Patients' photographs were analyzed for tip projection, nasolabial angle, and nasofrontal angle. The surgical methods were chosen on the basis of the anatomic part of the nose treated. Patient satisfaction was assessed.

Results: Of 279 participants, 210 (75.53%) had a chief complaint of a large nasal tip. A hump nose was a problem for 230 (82.44%) of the participants. Tip droop was a problem for 248 participants (88.89%). The number who wished to have a natural nose was 213 (76.34%), and 66 (23.66%) preferred to have an exaggerated nose. For the recall phase of the study, 248 patients (89 men, 159 women) agreed to participate. Men were more satisfied than women 1 year after rhinoplasty. Patients with an elevated tip had a higher satisfaction rate than others. The satisfaction level of patients increased when nose projection decreased.

Conclusions: It seems that tip defining and elevation were major concerns of Iranian surgeons. Iranian patients were satisfied with an elevated and low-profile tip.
