Abstract
BACKGROUND
Iranian people celebrate the last Wednesday of the year also known as Chahar Shambeh Soori (CSS) using
low explosive pyrotechnics classified as fireworks. Mishaps and accidents are common and maxillofacial fractures may occur which have a negative impact on the quality of life. This study aimed to assess maxillofacial fractures (fx) caused by explosive agents.
METHODS
This cross-sectional descriptive study assessed 283 patients suffering maxillofacial fxs caused by explosive agents during CSS ceremonies between 2009 and 2019 referred to our craniomaxillofacial (CMF) surgery center. The data assessed included age, sex, cause, type, site, and severity of injury, fracture patterns, treatment modalities, and complications. All maxillofacial injuries were evaluated and treated by Craniomaxillofacial staff surgeons.
RESULTS
Among 283 patients, 72.8% (206) and 27.2% (77) were men and women, respectively. The mean age of patients was 17.35 years. The most common maxillofacial fracture was in the mid-face; with the distribution of fractures being: 39.9% zygomatic fractures, 32.1% nasal bone fractures, 63.2% dentoalveolar fracture, 43.1% Le Fort (Le Fort I, Le Fort II, Le Fort III), 31.4% orbital, and 43.1% mandible fractures. The most frequent type of treatment was Open Reduction and Internal Fixation (ORIF) (77.4%).
CONCLUSION
The most common site of maxillofacial fractures and most frequent treatment used were similar to military or ballistic injuries. ORIF was common treatment.

Abstract
Background: The provision of sufficient stability after maxillofacial surgery is essential for the reduction of complications and disease recurrence. The stabilization of osteotomized pieces results in rapid restoration of normal masticatory function, reduction of skeletal relapse, and uneventful healing at the osteotomy site. We aimed to compare qualitatively stress distribution patterns over a virtual mandible model after bilateral sagittal split osteotomy (BSSO) bridged with three different intraoral fixation techniques.
Methods: This study was conducted in the Oral and Maxillofacial Surgery Department of Mashhad School of Dentistry, Mashhad, Iran, from March 2021-March 2022. The mandible computed tomography scan of a healthy adult was used to generate a 3D model; thereafter, BSSO with a 3mm setback was simulated. The three following fixation techniques were applied to the model: 1) two bicortical screws, 2) three bicortical screws, and 3) a miniplate. The bilateral second premolars and first molars were placed under mechanical loads of 75, 135, and 600N in order to simulate symmetric occlusal forces. Finite element analysis (FEA) was carried out in Ansys software, and the mechanical strain, stress, and displacement calculations were recorded.
Results: The FEA contours revealed that stress was mainly concentrated in the fixation units. Although bicortical screws presented better rigidity than miniplates, they were associated with higher stress and displacement readings.
Conclusion: Miniplate fixation demonstrated the most favorable biomechanical performance, followed by fixation with two and three bicortical screws, respectively. Intraoral fixation with miniplates in combination with monocortical screws can serve as an appropriate fixation arrangement and treatment option for skeletal stabilization after BSSO setback surgery.

Abstract
Background: Maxillofacial fractures are a common type of injury that can result in significant morbidity and mortality. We aimed to systematically review the literature on the prevalence and causes of maxillofacial fractures in Iran to estimate the overall prevalence of maxillofacial fractures and the most common causes.
Methods: A systematic search of PubMed, Cochrane Library, Web of Science (WS) and Google Scholar (GS) electronic databases was conducted to identify relevant articles published up to January 2023. Studies reporting the prevalence and causes of maxillofacial fractures in Iran were included in the analysis. MOOSE guidelines were adopted for the current systematic review. No data or language restriction were applied. Risk of bias across the articles was assessed.
Results: A total of 32 studies comprising 35,720 patients were included in the analysis. The most common cause of maxillofacial fractures was road traffic accidents (RTAs), accounting for 68.97% of all cases, followed by falls (12.62%) and interpersonal violence (9.03%). The prevalence of maxillofacial fractures was higher in males (81.04%) and in the age group of 21-30 years (43.23%). Risk of bias across studies was considered low.
Conclusion: Maxillofacial fractures are a significant public health problem in Iran, with a high prevalence and RTAs being the leading cause. These results highlight the need for increased efforts to prevent maxillofacial fractures in Iran, especially through measures to reduce the incidence of RTAs.

Abstract
Background: The aim of this study was to systematically review the literature on the treatment options of maxillofacial fractures in Iran, complementing a previous article regarding causes and the overall prevalence.
Methods: A systematic search of PubMed, Cochrane Library, Web of Science (WS) and Google Scholar (GS) electronic databases was conducted to identify the relevant articles published up to January 2023. Studies reporting the treatment option of maxillofacial fractures in Iran were included in the analysis. MOOSE guidelines were adopted for the current systematic review. No data or language restriction were applied. Risk of bias across the articles was assessed.
Results: This systematic review included 13 articles with a total of 19,147 treated patients for maxillofacial fractures. ORIF was the most common type of treatment, but complications occurred in approximately 5% of cases. Mandible fractures were not statistically more treated by ORIF than closed reduction or conservative treatment, and no type of treatment was considered statistically preferable depending on the anatomical region affected by Iranian maxillofacial surgeons. The included studies were considered to have a low risk of bias, but many were not clear in reporting cross-referenced data regarding the type of treatment, which could be considered a major flaw.
Conclusion: Overall, this study provides valuable insights into the types of treatment used for maxillofacial fractures by Iranian surgeons and highlights the importance of clear reporting of data in research articles.

Abstract
Background: We aimed to investigate the pharmacological and non-pharmacological interventions used for mitigating pain.
Methods: We integrated randomized controlled trials (RCTs) chosen from PubMed, Google scholar, and Scopus and aimed at assessing the effectiveness of one or multiple variants of Non-steroidal anti-inflammatory drugs (NSAIDs), as well as Narcotic analgesics, compared to corticosteroids, curcumin, hyaluronic acid, and antibiotics. In addition, trials utilizing NSAIDs, including Rofecoxib, which have been withdrawn from market circulation, were deemed ineligible for inclusion.
Result: A total of 9 RCTs were evaluated in this study, and the patients' postoperative pain was assessed using the visual analog scale (VAS) and the time measurement. Moreover, there were various approaches to alleviating pain and discomfort.
Conclusion: The administration of ibuprofen prior to surgery leads to a marked reduction in pain. Pharmacological interventions, such as the administration of dexamethasone and oxycodone, alongside non-pharmacological interventions, such as laser therapy, have been shown to effectively alleviate the discomfort resulting from surgical procedures on the jaw and face.

Abstract
Background: The purpose of the present study was to evaluate the changes in maxillofacial fracture epidemiology and etiology regarding Covid-19-related social distancing restrictions in an Iranian population.
Methods: A retrospective cross-sectional study was undertaken in six major trauma center hospitals in Iran in a period of two years (March 2018 until March 2020). The primary outcome variable was the maxillofacial fractures incidence. Patients’ demographic data, date of injury as well as fracture characteristics, fracture etiology, type, and site were all recorded, compared, and analyzed in the control and experimental groups.
Results: The patients consisted of 520 (83.6%) males and 102 (16.4%) females. Patients sustaining maxillofacial fractures over this two-year period displayed a mean age of 31.24±14.44, with an age range of 2 to 88 years. The incidence of maxillofacial fractures significantly decreased in all age groups (p<0.001). After social distancing restrictions were placed; there was a significant drop in the number of subjects attending due to motorcycle collisions and road traffic accidents, whereas the number of fractures caused by assaults and domestic violence significantly increased (p<0.001 for each).
Conclusion: The investigators realized that social distancing restrictions were able to change the trends and patterns in maxillofacial fracture incidence and etiology.

Abstract
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.
