RESUMO

BACKGROUND: Periorbital edema and ecchymosis are frequently encountered after rhinoplasty and may be distressing to patients. Cold therapy is frequently employed in rhinoplasty to reduce postoperative edema and ecchymosis. PURPOSE: The aim of this study was to evaluate the effect of cold saline irrigation (CSI) of dissection planes in rhinoplasty on postoperative edema and ecchymosis. STUDY DESIGN, SETTING, SAMPLE: The investigators designed a retrospective cohort study. The data of patients who underwent rhinoplasty in our clinic between January 2021 and January 2023 were scanned. Patients who underwent primary open rhinoplasty from the same surgeon and standard rhinoplasty steps were applied in the same way and order were included in the study. Patients who had systemic diseases and previous nose surgery, and patients whose photographs could not be accessed from the photograph archive were excluded. PREDICTOR VARIABLE: According to whether CSI was applied to the dissection plans during rhinoplasty, the patients were divided into the CSI group and the control group (without CSI). MAIN OUTCOME VARIABLES: Patients' grades of periorbital edema and ecchymosis were the main outcome variables. The differences of outcome variables were compared between the 2 groups. COVARIATES: Demographics (age, sex), and surgical detail (duration of surgery) were collected as covariates. ANALYSES: The numerical variables were compared between the two groups using the student's t-test and Mann-Whitney U test, whereas the categorical variables were compared using Pearson's χ2 and Fisher's exact tests. P < .05 was considered statistically significant. RESULTS: Among the 167 patients who met the inclusion criteria, 60 patients were randomly selected, 30 patients in each group. No statistically significant difference was found between the two groups in terms of age (P = .45) and sex (P = .27). The mean ecchymosis grade was statistically significant lower in the CSI group than in the control group for all evaluation times (P < .05). Similarly, the mean edema grade was statistically significant lower in the CSI group than in the control group for all evaluation times, with the exception of the 10th and 15th day (P < .05). CONCLUSION AND RELEVANCE: CSI of the dissection planes in rhinoplasty reduced the development of periorbital edema and ecchymosis. This procedure is straightforward, inexpensive, and effective.

RESUMO

BACKGROUND/AIMS: Various tissue preservation solutions are used during the removal of the organ and during transplantation to protect the normal histological and biochemical characteristics of tissue while performing a successful liver transplant. In our study, it was aimed to investigate the effects of intraperitoneal melatonin administration on liver preservation damage before transplantation. MATERIALS AND METHODS: In our study, the histological and biochemical characteristics of University of Wisconsin+melatonin group rats treated with melatonin 45 minutes before hepatectomy were compared between serum physiologic group and University of Wisconsin group. RESULTS: When hematoxylin and eosin staining was evaluated in terms of hydropic degeneration, sinusoidal dilatation, and hepatocyte necrosis, there was no statistically significant difference. Caspase 3 immunohistochemical staining showed a significant increase in Caspase 3 immunoreactivity positivity at the 12th-hour University of Wisconsin group compared to University of Wisconsin+melatonin group. As a result of biochemical analysis, the malondialdehyde and total oxidant status levels in the University of Wisconsin+melatonin group decreased significantly compared to the University of Wisconsin group. When the reduced glutathione activity and total antioxidant capacity level were compared, a significant increase was observed in the University of Wisconsin+melatonin group compared to the University of Wisconsin group at the 12th hour. It was also found that aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase levels decreased significantly in the University of Wisconsin+melatonin 12th-hour group compared to the University of Wisconsin 12th hour and control group. CONCLUSION: When the findings were evaluated, intraperitoneal administration of melatonin, a cytoprotective antioxidant, was found to play an effective role in preserving immunohistochemical and biochemical properties of liver tissue integrity and hepatocytes in University of Wisconsin solution.

RESUMO

BACKGROUND: Ischemia-reperfusion injury is a histopathological event and is an important cause of morbidity and mortality after hepatobiliary surgery. We aimed to investigate the protective effect of uridine on hepatic ischemia-reperfusion injury in rats. METHODS: The animals were divided into 4 groups (n = 8): group I (control), group II: ischemia-reperfusion (30 minutes ischemia and 120 minutes reperfusion), group III: ischemia-reperfusion+uridine (at the beginning of reperfusion), and group IV: ischemia-reperfusion+uridine (5 minutes before ischemia-reperfusion). Uridine was administered a single dose of 30 mg/kg IV. The 3 elements of the hepatoduodenal ligament (hepatic artery, portal vein, and biliary tract) were obliterated for 30 minutes. Then hepatic reperfusion was achieved for 120 minutes. RESULTS: In the ischemia-reperfusion group, both liver tissues and serum chymase activity and high-temperature requirement A2 levels were higher. Severe central vein dilatation and congestion, widening sinusoidal range, diffuse necrotic hepatocytes and dense erythrocyte accumulation in sinusoids, and strongly inducible nitric oxide synthase expression were seen in the ischemia-reperfusion group. A clear improvement was seen in both uridine co-administration and pretreatment groups. CONCLUSION: Our results revealed that uridine limits the development of liver damage under conditions of ischemia-reperfusion, thus contributing to an increase in hepatocyte viability.

RESUMO

PURPOSE: The aim of this study was to investigate the effects of traditional thermoplastic splints vs a 3D-printed custom external nasal splint designed to apply pressure to the lateral osteotomy lines and neighboring periorbital region on edema and ecchymosis after rhinoplasty. PATIENTS AND METHODS: Forty patients undergoing open rhinoplasty were included in this prospective randomized controlled study. The patients were divided into 2 groups. In the study group, the new 3D-printed custom external nasal splint was used. In the control group, the thermoplastic external nasal splint was used. Periorbital edema and ecchymosis scores were assessed peroperative before external nasal splint application, postoperatively at the 1st and 4th hours, and 1st, 2nd, 5th, 7th, 10th, and 15th days. RESULTS: There were lower scores of ecchymosis and edema in the study group compared to the control group for all the follow-up controls. There was a significant difference between the 2 groups with respect to the occurrence of ecchymosis for all follow-up controls except for the first postoperative hour and the seventh postoperative day (P < .05). Comparison of the 2 groups with respect to the grade of edema showed a significant difference only in the first and fourth postoperative hours (P < .05). CONCLUSIONS: The study detected less edema and ecchymosis scores using this 3D custom external nasal splint, thus creating a new area of use for 3D printers in the field of facial esthetic surgery. New thermoplastic splints of different shapes and sizes can be produced that can compress the osteotomy lines and the neighboring periorbital region.

RESUMO

PURPOSE: The aim of this study is to review the aesthetic and functional outcomes of septorhinoplasty using questionnaires that have never been collectively used, as well as surgeons' evaluation. MATERIALS AND METHODS: Our study was conducted prospectively among 100 patients who underwent septorhinoplasty operation. We evaluated the effects of septorhinoplasty's functional and aesthetic outcomes on patients' emotional status using a combination of NOSE, ROE, DAS-24, and GBI questionnaires as well as surgeons' evaluations. RESULTS: Our study did not detect any significant difference between preoperative and postoperative levels of patient satisfaction with regard to age, sex, and surgery type and the number of surgeries. Our study, on the other hand, revealed significantly higher postoperative GBI scores among patients with higher preoperative DAS-24 and NOSE scores. However, we showed no significant difference between the preoperative ROE score and postoperative GBI score CONCLUSION: This study demonstrated that septorhinoplasty can not only significantly alter a nose's functional and aesthetic appearance, but it can also boost patient satisfaction.
