Objectives: The study aimed to determine the importance of using thermoplastic splinting versus non-thermoplastic splinting in protecting nose external structures post-surgery, particularly swelling effects, using a post-rhinoplastic scoring system ranging from 0 to 4, considering factors like dexamethasone IV administration. Methods:Between 2019 and 2023, a retrospective study at Hashemite University in Zarqa, Jordan, examined patients who had different types of rhinoplastic surgery. The study excluded patients with previous maxillofacial interventions, cardiovascular or coagulopathy disorders, or high blood pressure. Patients were categorized into two groups based on whether they had thermoplastic splints put on after rhinoplasty. The study used a chi-square test to compare the distribution rates of independent variables across the groups. The study examined the statistical link between the amount of dexamethasone given intravenously before surgery and patients' post-procedural swelling.A multiple logistic regression analysis and one-way multivariate analysis of covariance were conducted to revealed the clinical significance of adopting thermoplastic splinting over non-thermoplastic strategy in reducing the post rhinoplastic complications of particular swelling while accounting for the cumulative perioperatively administered dexamethasone IV. Results:A study involving 269 patients found that 45.35% of patients underwent rhinoplastic surgery without TP splinting, while 54.65% underwent TP splinting. The study included 143 women (53.2%) and 126 men (468.8%). The rates of bruising and swelling after surgery were similar between groups. However, there was no significant difference in periorbital ecchymosis scores between groups. The study also found no significant difference in comorbidity burden between the two groups. The study also found no significant difference in the percentage of obese patients based on their body mass indexes.A study examining the impact of tranexamic acid (TP) and multivitamins (MVs) on ecchymosis and swelling after nose plastic surgery found no significant difference between non-TP and TP groups. The study also found no significant difference in the rates of regular MVs supplementation. The researchers used a receiver operating characteristic (ROC) curve to analyze the effect of ΣDex IV on swelling risk. The results showed that a swelling score of >1 had clinically useful results, while a score of 3 had significant clinical utility. Conclusion:The one-way multivariate analysis of covariance and the multiple logistic regression analysis show that using thermoplastic splinting instead of non-thermoplastic splinting significantly reduced the risk of swelling after rhinoplasty. According to this study, using thermoplastic splinting may be a good idea. It could be an effective clinical addition to corticosteroid therapy to reduce swelling after rhinoplasty and provide long-lasting positive aesthetic effects.
