RESUMO
Background: Trauma is a leading cause of death and disability in developing countries, with maxillofacial fractures being a significant part of such cases. This study focuses on maxillofacial traumas among insured patients in Razavi Khorasan province (2016-2021), exploring the impact of gender, age, and trauma causes on injury prevalence and treatment approaches. Methods: This retrospective cross-sectional study utilized the records of the patients who were treated for maxillofacial fractures in Mashhad Shahid Kamyab Hospital or a Private Trauma Center, from 2016 to 2021. Demographic characteristics of the patients (age and gender), educational backgrounds of surgeons, accident causes, year and location of the fractures, and reasons for referrals were recorded. The data were statistically analyzed using SPSS 20, and the significance level was set at 0.05. Results: We examined the records of 60 patients (44 males, 16 females). Males (73.4%) exhibited a significantly higher prevalence of maxillofacial traumas compared to females (26%) (P Value < 0.05). Falling was identified as the most common cause of fractures (51.7%), followed by impacts from hard objects and motor vehicle accidents (MVA) (P Value = 0.63). Mandible fractures were observed in 48% of patients, followed by zygomaticomaxillary and panfacial fractures, subsequently (P Value < 0.05). Conclusion: The study findings highlight the impact of age, gender, and trauma causes on maxillofacial fractures and treatments among patients with certain insurance. Understanding the origins and patterns of these fractures offers crucial insights for shaping effective health policies, providing valuable guidance for addressing such injuries in this population.
RESUMO
Background: We aimed to investigate the effect of preoperative administration of oral tizanidine on postoperative pain intensity after bimaxillary orthognathic surgery. Methods: All healthy skeletal class III patients who were candidates for bimaxillary orthognathic surgery were enrolled in this triple-blind randomized clinical trial. The study was carried out in the Maxillofacial Surgery Department of Qaem Hospital, Mashhad, Iran; from January 2021 to November 2021. The consecutive patients were randomly divided into tizanidine and placebo groups. One hour prior to anesthesia induction, the tizanidine group received 4 mg Tizanidine dissolved in 10 ml apple juice, whereas the placebo group received an identical glass of plain apple juice. All operations were performed by the same surgical team, under the same general anesthesia protocol. Postoperative pain was measured using the Visual Analogue Scale (VAS) at 3, 6, 12, 18, and 24 hours. For statistical analysis; the significance level was set at 0.05 using SPSS 23. Results: A total of 60 consecutive patients, consisting of 36 females (60%) and 24 males (40%) with an average age of 25.4 ± 6.0 were recruited. An increasing trend was noticed in the amount of perceived postoperative pain from the 3rd till 12th hour, and then decreased afterward. Nevertheless, the average amount of pain was significantly lower in the tizanidine compared to the placebo group, in all the evaluated time intervals (P<0.001). Moreover, there was a significantly higher requirement for postoperative opioid analgesics in the placebo compared to the tizanidine group (P=0.011). Conclusion: The addition of oral tizanidine was effective in reducing postoperative pain following bimaxillary orthognathic surgery. Further studies are necessary for more relevancy.
