RESUMEN

This study aimed to critically reanalyze systematic reviews of patients suffering from condylar resorption (CR) and summarize the current scientific pieces of evidence with a focus on a possible relationship between CR and orthognathic surgery (OS). The work followed the "Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocol" guidelines and was registered in the International Prospective Register of Systematic Reviews (registration number: CRD42020168660). The search strategy produced 143 articles. After reading the abstracts, 113 articles were excluded, and the full-text articles in English of the remaining 30 studies were separately examined for eligibility by 2 authors, with 20 of them being excluded because they did not meet the inclusion criteria. Finally, 10 systematic reviews were processed for critical evaluation. Young female patients with a high mandibular plane angle, diminished posterior facial height, posteriorly inclined condylar neck, and a counter-clockwise jaw rotation, are more likely to develop CR after OS. The most common procedure associated with CR in the included systematic reviews was the bimaxillary OS followed by bilateral sagittal split osteotomy. Hence, extreme caution and surgical modification should be used in these high-risk conditions. There is still a need for more evidence on the risks of OS or iatrogenic factors during the fixation of various osteosynthesis devices because it is still inconclusive and requires further justification.

RESUMEN

OBJECTIVE: Resistance of Staphylococcus aureus (S. aureus) against common antibiotics has been increasing given the rampant use of antibiotics. Methicillin-resistant S. aureus (MRSA) is particularly important because it has been reported to present in hospital-acquired as well as community-acquired infections. Our aim was to study the types and subtypes of MRSA isolated from nasal swabs taken from volunteering dental school students and to assess and analyse the knowledge of dental health care workers (DHCWs) on MRSA and prevention of its infection. METHODS: A total of 100 participants, which included staff, students, and dental auxiliaries, from the School of Dental Sciences, Krishna Institute of Medical Sciences, Deemed to Be University, Karad, India, were included in the study which was conducted from June 2020 to 1 June 2021. All the participants completed a survey and underwent collection of nasal swabs. The samples were cultured and underwent microbiological and molecular analysis for MRSA. The questionnaire was sent out electronically via SurveyMonkey. RESULTS: Sixty-three percent of the participants were female. The majority were undergraduate students (66%) and younger than 25 years (77%). The prevalence of MRSA in the sample was the MRSA type SCCmec type V (54.8%). The survey reports a lack of knowledge amongst dental students on MRSA and prevention of its infection. The majority (69%) of participants had not heard of MRSA infection and had inadequate knowledge of MRSA infection. Only 29% of the participants think that a healthy person may have MRSA without feeling ill. Eighty-five percent of the participants reported that they have written polices and guidelines to control MRSA. Eighty-five percent of the participants indicated that they are less confident in their knowledge on MRSA infection control protocols, and 94% mentioned that the dental clinics have written guidelines for hand hygiene. CONCLUSIONS: DHCWs have limited knowledge of MRSA infection, emphasising the need for appropriate clinical training. Academic institutions should promote effective infection control training to protect students, faculty, and other employees.

RESUMEN

PURPOSE: Oral submucous fibrosis (OSMF) is a chronic, potentially malignant condition affecting any part of the oral cavity and is prevalent in Southeast Asia and the Indian subcontinent. The aim of this study is to compare the efficacy of buccal fat pad flap with the nasolabial flap in the management of OSMF. METHODS: We systematically compared two commonly used constructive techniques in the management of OSMF: the buccal pad of fat flap and the nasolabial flap. We performed a comprehensive search in four databases for all articles published between 1982 and November 2021. We assessed the risk of bias using the Cochrane Handbook and Newcastle-Ottawa Scale. We used the mean difference (MD) for pooling the data with 95% confidence intervals (CIs) and evaluated the heterogeneity between pooled studies using χ2 and I2 tests. RESULTS: Out of 917 studies, six were included in this review. The meta-analysis significantly favored conventional nasolabial flap over buccal fat pad flap in improving the maximal mouth opening (MD, - 2.52; 95% CI, - 4.44 to - 0.60; P = 0.01; I2 = 0%) after OSMF reconstructive surgery. Conversely, when it comes to esthetic outcomes, these studies favored buccal fat pad flap. CONCLUSION: Our meta-analysis found that nasolabial flap was better than buccal fat pad flap in terms of mouth opening restoration after OSMF reconstructive surgery. Also, the included studies found better results, favoring nasolabial flap over buccal fat pad flap in terms of oral commissural width restoration. Also, these studies reported better outcomes in terms of esthetics, favoring buccal fat pad flap. Further studies with larger sample sizes and different populations/races are needed to confirm our findings.

RESUMEN

Background/Objectives: The use of miniplates for stabilizing bones post orthognathic surgery has surged in popularity due to their efficacy in ensuring stability and hastening recovery. However, controversy exists regarding what should be done with these miniplates after surgery. Some surgeons advocate for their removal, while others suggest leaving them in place. This study sought to assess the frequency, causes, and potential risk factors linked with miniplate removal in orthognathic procedures. Methods: A thorough meta-analysis was conducted by scrutinizing studies from various databases including PubMed, Google Scholar, Embase, and Scopus, focusing on publications spanning from 1989 to 2023. Results: Ten studies meeting the inclusion criteria, encompassing 1603 patients, were chosen for inclusion in the meta-analysis. The male-to-female ratio varied from 0.7:1 to 4:1. Overall, 5595 miniplates were inserted, with 294 (5.3%) being subsequently removed. Primary reasons for miniplate removal included infection (161 cases, 2.9%), exposure of miniplates (34 cases, 0.6%), and palpable plates (23 cases, 0.4%). Other indications comprised pain, patient preference, and temperature sensitivity. Less frequent causes for miniplate removal included sinusitis, secondary surgery, and dental pathology. The mean duration of miniplate removal was 5.5 months, with the majority (56.1%) being removed from the mandible rather than the maxilla. In conclusion, this meta-analysis underscores the importance of miniplate removal when hardware causes complications and physical discomfort. The primary reasons for removing miniplates were infection and plate exposure, with the mandible being the most common removal site. Conclusions: These findings emphasize the need for continued monitoring to assess the fate of miniplates in orthognathic surgery and provide valuable information for future clinical decision-making.

RESUMEN

BACKGROUND: Intraoral adenoid cystic carcinoma (ACC) arising from minor salivary glands (MSG) is a rare malignancy associated with delayed diagnosis and unfavorable outcomes. This study aimed to comprehensively review ACC of MSGs, focusing on clinical characteristics, imaging modalities, treatment approaches, and long-term outcomes. METHODS: A systematic search was conducted in PubMed, Web of Science, and MEDLINE databases to identify relevant articles reporting cases of ACC of MSGs between January 1997 and March 2023. The study was registered in PROSPERO (ID: CRD42023449478). A total of 10 studies that met the inclusion criteria were selected for critical review. In total, 902 patients were diagnosed with ACC of MSGs with an age range of 44.3 to 63 years, and an average age of 56.6 years. The female to male ratio ranges from 1:1 to 2.4:1. Regarding the primary site of ACC, the palate was the most common location, accounting for 30.5% to 83.3%, followed by the buccal mucosa, floor of the mouth, and lip and the retromolar area. For histology, the solid mass pattern was the most prevalent, seen in 95.2% of patients, followed by the cribriform pattern. Regarding treatment modalities, surgery was the most common approach, applied in 76.3% of cases, with a combination of surgery and radiotherapy used in 29.0% of cases. A smaller fraction, 3.2%, received a combination of surgery, chemotherapy, and radiotherapy, and 8.3% underwent radiotherapy alone. Local recurrence rates varied between 1% and 28.5%, and distant metastasis occurred in 18.2% to 33.3% of cases, predominantly to lymph nodes (14.5%). An analysis of overall survival across various stages and patient numbers indicated a 5-year survival rate of 68.0%. The findings of this study provide valuable insights for physicians in making treatment decisions and emphasize the need for ongoing research and collaborative clinical efforts to improve the management and outcomes of this challenging disease. CONCLUSION: ACC of MSGs is a multifaceted condition typically manifesting as asymptomatic enlargement and ulceration. This disease is marked by distinct histopathological patterns and perineural invasion (PNI). Recognizing these distinctive aspects is key in shaping the treatment plan, which can range from surgical procedures to radiation therapy, chemotherapy, and evolving targeted treatments. Continuous research and collaborative clinical efforts remain critical for ongoing progress in the treatment and management of this challenging condition.

RESUMEN

Personal identification in forensics is possible with gender determination using DNA (deoxyribonucleic acid) analysis. DNA isolation from teeth samples subjected to extreme temperatures has been shown to predict the gender of the deceased. However, the literature lacks studies on DNA extracted from tooth samples exposed to freezing temperatures. This study aimed to isolate the SRY gene from the extirpated pulp of teeth that were subjected to varying temperatures for gender identification. Thirty teeth with vital pulps, divided into 3 groups were included in the study. Each group consisted of 5 male and 5 female tooth samples. The groups were exposed to diverse environmental factors for three weeks. Group 1: room temperature (R group); Group 2: high temperature (H group) and Group 3: freezing temperature (F group). Later, DNA was isolated from the pulp tissue, and the SRY gene was amplified using PCR (Polymerase Chain Reaction). The Sensitivity and Specificity of the results were analyzed. SRY gene detected in the study samples identified accurate gender with a 46.70% Sensitivity and 93.30% Specificity. Significant difference was found in the correlation between gene expression and gender among the three groups (p = 1.000). The study validates that dental pulp tissue can be a reliable source for DNA extraction. And SRY gene amplification from teeth exposed to diverse environmental conditions. Further investigations are required to validate its application in forensics.

RESUMEN

Aim/Objective: This umbrella review of systematic reviews aims to summarize the available data regarding both success and survival rates of tooth autotransplantation, in addition to analyzing the risk factors that are connected to those rates. Methods: This umbrella review was performed according to the evaluation of various meta-analyses and systematic reviews following AMSTAR2 guidelines. A systematic search of literature on PubMed, Scopus, MEDLINE, EMBASE, and the Cochrane Database. Six systematic reviews were included. Explicit inclusion and exclusion criteria were applied. It is registered in PROSPERO under the registration number (CRD-42023415623). Results: The studies reviewed were written from 2014 to 2018, which extracted the information from various studies spanning from 1968 to 2014. According to the selected studies regarding autotransplanted teeth in humans, they showed the following: A survival rate overall of 87.39% and a success rate overall of 90.29%. These factors were the most common in relation to the success of the autotransplanted teeth: age, gender, and stage of root development. On the other hand, common unfavorable results linked to the transplanted teeth in these studies were failure, ankylosis, and internal root resorption, followed by extraction and hypermobility. Conclusions: The wide body of evidence gathered illustrates that autotransplantation is an operation that dispenses high rates of survival and success. Furthermore, risk factors like root development stage, recipient site, and donor tooth type established a remarkable association with the negative outcomes of the procedure. For successful tooth autotransplantation, patient selection is crucial. Younger patients and those with donor teeth at an optimal stage of root development typically experience better outcomes. Preoperative planning should include comprehensive evaluations and advanced imaging techniques to accurately assess both the donor tooth and the recipient site. Nonetheless, on account of heterogeneity and the quality of the studies included in this investigation, caution should be taken when interpreting the mentioned results.

RESUMEN

Background: The study aims to investigate parameters in patients attending Fujairah Dental Center, including assessing the prevalence of impacted teeth, determining the frequency of associated pathological conditions, and evaluating the patterns and angulations of impacted third molars. Methods: It is a retrospective descriptive study of the panoramic radiographs of patients who attended Fujairah Dental Center for dental care between January 2011 and December 2017. The minimum age for inclusion was 17 years. Clinical records were used to obtain the demographic details of patients, such as age, gender, nationality, medical history, and smoking history. Seven hundred and four panoramic radiographs and clinical records of patients were analyzed. The age range was between 17 and 112 years old, with a mean age of 34 years (S.D 13.5). Results: Of the 704 panoramic radiographs evaluated, 236 (33.6%) X-rays showed teeth impaction with a total of 562 impacted teeth in the upper and lower jaws. Five hundred and twenty-five (93.4%) were impacted third molars, and 37 (6.5%) teeth were other kinds of impacted teeth. Females showed a higher frequency of impacted teeth (62.6%) compared to males (37.4%). The highest prevalence of impacted teeth was found in the 17-25 year age group (61%), and the prevalence declined with advancing age. Impacted third molars were more likely to occur in the mandible (57.3%) than in the maxilla (42.7%). Most of the impacted third molars were in the mesioangular position, followed by the vertical position. The evaluation of the depth of impacted third molars demonstrated that level C impaction was the most frequently seen, followed by level B impaction. Impacted third-molar teeth often presented with two roots (60.7%), followed by a single root (31.3%). An evaluation of the relationship between lower third molars and the inferior dental canal (IDC) revealed that the most frequently observed relation was interrupted (61.5%), followed by a distant relation to the ID canal, and 13% were superimposed. The most common morphological pattern of roots of the impacted third molars was either straight-type or curved and dilacerated roots (5.7%). Additionally, the most noticed pathological conditions associated with impacted teeth were carious second molars adjacent to impacted third molars (42%), which was more likely to be seen in the 17-25-year age group, with females having a higher prevalence than males.

RESUMEN

In dentistry, occupational contact dermatitis may affect dental professionals along with technicians, nurses, and patients. Changes to dental practice in recent years have altered the reported frequencies of allergens causing contact dermatitis in both dental professionals and dental patients. In the current cross-sectional study, we used a structured questionnaire and clinical examinations to examine the prevalence of self-reported hand eczema among United Arab Emirates (UAE). The relationship between subjective skin discomfort and latex, composite/bonding, or other dental materials also was explored. A structured questionnaire was designed to analyze the prevalence of skin conditions among dental professionals and study its implication in gender, occupation, and age groups. The questionnaire included information about skin symptoms, atopy, occupational experience, and other background factors like respiratory symptoms, work history and methods, and exposure at work. It was distributed to 550 randomly selected dental healthcare professionals. Out of 550 dental healthcare workers contacted, 434 responded giving a response rate of 79%. The prevalence of dry and rough skin on the hands was highest (45%). There was a total of 29 cases of allergic contact dermatitis, 15 cases of contact urticaria, 12 cases of irritating contact dermatitis, and 1 incidence of onychomycosis among the 100 dental healthcare professionals who reported having dermatitis on their hands, forearms, or faces due to their daily dental chores. Rubber chemicals and natural rubber latex (NRL) in protective gloves used by dentists, as well as dental-restorative plastic materials (methylacrylates), were the most common causes of allergy. Dry skin and hand eczema were more common among dental healthcare professionals. Plastic gloves or NRL gloves with a low protein content are recommended for dental work. Skin exposure to methylacrylates or latex should be avoided.

RESUMEN

This study aimed to compare condylar bony pathology in patients with and without temporomandibular joint disorder (TMD) using orthopantomography at Ajman University dental clinics between 2017 and 2021. Patient data from the Ajman University archives were collected after obtaining ethical approval. OPG (orthopantomogram) views were evaluated for potential TMJ pathology. Three independent observers underwent calibration and image analysis, with their agreement level calculated using Kappa statistics (score 0.781). Condylar changes were coded from 0 to 6. Statistical tests such as the Mann-Whitney Test, Kruskal-Wallis test, Spearman's correlation, and logistic regression analysis were used to analyze the data. The inter-examiner reliability for OPG was 0.903, and intra-examiner reliability was 0.908. The most common condylar bony changes observed in OPG views were flattening and osteophyte. Female participants had a higher prevalence of all bony changes. Temporomandibular Disorder (TMD) can manifest with symptomatic and detectable bony changes in OPG views. The prevalence of temporomandibular disorder appeared similar between genders, but differences were observed regarding the number of teeth lost, with unilateral tooth loss being more common. Interestingly, bruxism did not seem to significantly impact of temporomandibular disorder patients.

RESUMEN

PURPOSE: Is to systematically review the available evidence of the patient's nutritional state before and after orthognathic surgery METHODS: The protocol to the International Prospective Register of Systematic Reviews (PROSPERO; registration No. CRD42020177156). RESULTS: The search strategy yielded a total of 43 articles from all databases. Of the 43 articles, 13 were excluded after an examination of the titles and abstracts, and full-text articles of the remaining 30 studies were reviewed independently for eligibility. Of these 30 studies, 23 were excluded because they did not meet the inclusion criteria. Finally, a total of 7 studies met the inclusion criteria and were processed for critical review CONCLUSION: Patient's body weight and body mass index (BMI) decreases after orthognathic surgery. No significant changes in body fat percentage were observed. The estimated blood loss and the need for blood transfusion increased. No significant changes were observed in hemoglobin levels, lymphocyte counts, total cholesterol levels, and cholinesterase levels between the pre-operative and postoperative periods. Increments in serum albumin levels and total protein counts were observed after orthognathic surgery.

RESUMEN

OBJECTIVES: The aims of this paper were twofold: first, to evaluate dental anxiety levels among patients undergoing oral surgery procedures; second, to assess how dental anxiety and fear are connected to age, gender, educational background, past traumatic experiences, and the frequency of dental appointments. METHODS: A cross-sectional Likert-scale questionnaire survey was conducted to collect quantitative data from 206 patients at the Oral Surgery Clinics at Dubai Dental Clinics, Dubai, United Arab Emirates. The reliability and validity of the questionnaire were tested using Cronbach's alpha. The normality of the MDAS score was tested using the Kolmogorov-Smirnov test. The chi square and Kruskal-Wallis tests were used to determine the association between categorical variables. Descriptive statistics were used to describe continuous and categorical variables. The statistical significance was set at p-value ≤ 0.05. RESULTS: The evaluation of the degree of dental anxiety among patients who visited the Dubai Dental clinics revealed that there was a considerably high level of moderate or high anxiety (72.3%). Tooth extraction and dental surgery procedures (95%), followed by local anesthetic injection in the gingiva (85%) and teeth drilling (70%), were the primary causes of anxiety, whereas scaling and polishing resulted in the lowest degree of anxiety (35%). There was no substantial difference in dental anxiety between male and female patients or among patients with different marital statuses. A total of 70% of patients preferred the tell-show-do method, whereas 65% chose communication strategies to reduce dental anxiety. CONCLUSIONS: The evaluation of the degree of dental anxiety among patients who visited Dubai Dental clinics revealed that there was a considerably high level of anxiety. Tooth extraction and dental surgery procedures, followed by local anesthetic injection and teeth drilling, were the primary causes of anxiety, whereas scaling and polishing resulted in the lowest degree of anxiety. Despite the use of a modified anxiety scale and a large and representative sample of oral surgery patients, more research is necessary to investigate the impact of various factors on dental anxiety.

RESUMEN

Traumatic brain injuries (TBIs) associated with maxillofacial fractures (MFFs) are a public health concern worldwide, especially among adult-aged males. There is an urgent need for early detection of associated TBIs in patients with MFFs during the initial assessment and treatment stage to reduce morbidity and mortality. The objective of the present study was to systematically review the literature to determine specific MFF situations associated with TBIs and to identify the factors associated with TBIs in patients with MFFs. The protocol was developed in accord with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols (PRISMA-P) and was registered to the International Prospective Register of Systematic Reviews (PROSPERO) under the registration number CRD42020155912. Overall, of 26,774 patients recorded, 13,667 patients (51.04%) sustained MFFs with an associated TBI. The male to female ratio was 4.8:1. RTA was the most common cause. The most common TBIs were concussions, contusions, and closed brain injuries. Within the limits of this study, it was concluded that TBI-related MFFs should be suspected whenever maxillary or mandibular bone fractures occur, especially among adults, males, and people with injuries caused by RTAs and assaults. There is a need to increase the awareness of maxillofacial surgeons on the possible associations of combined maxillofacial trauma and brain injuries.

RESUMEN

METHODS: The study includes all fifth-year dental students registered at the College of Dentistry, Ajman University, in 2019/2020. One hundred and seventy students were invited to complete personality and performance measures using the Big Five Inventory (BFI) scale; the weighted grade point average (GPA) was used to assess students' academic performance. RESULTS: Of the 170 participants, 60% were female and 40% were male. Participants ranged in age from twenty-four to twenty-seven years, with an average age of twenty-four years. There was a relationship between personality scores obtained for the students and their subsequent academic performance. The broad conscientiousness, competence, achievement, and dutifulness predicted academic and clinical success. The prediction accuracy of conscientiousness was improved by the inclusion of dutifulness, self-discipline, and deliberation. CONCLUSION: This study confirms that the students' personality profile is a substantial predictor of academic performance and likely to help select future intakes of students, although a prospective study would be required for a definite answer to this question.

RESUMEN

BACKGROUND/PURPOSE: Oral epithelial dysplasia (OED) is characterized histopathologically by cellular and morphological changes that remain the single most important factor predicting risk for subsequent development of invasive neoplasia. Hence the aims of the present study were to determine the rate of malignant change of OED in a group of patients followed-up for a number of years, and hence determine factors likely to influence this malignant change, and to describe the clinical characteristics of patients who developed recurrence of OED and second dysplastic lesions. MATERIALS AND METHODS: This is hospital based cross-sectional study of all biopsy reports with histologically confirmed OED between 2012 and 2018 were retrospectivelly reviewed. RESULTS: A total of 359 patients with histologically confirmed OED were reviewed, twenty (5.5%) of the 359 patients developed an invasive squamous cell carcinoma (SCC) of the oral mucosa over a period of 2 to 274 months with mean transformation time of 3.3 years. CONCLUSION: The high risk of malignant transformation of OED seems to be related to patients older than 50 years when lesions were on the floor of mouth with severe dysplastic changes.

RESUMEN

PURPOSE: The purpose of this case report is to present a rare case of amlodipine-induced gingival overgrowth with a secondary formation of necrotizing ulcerative gingivitis involving the upper and lower arches of a 68-year-old female patient with a chief complaint of "swollen gums and pain on mastication which has been recurring for the past 5 years." MATERIALS AND METHODS: The treatment plan of this case was divided according to quadrants of the mouth. Each week, one quadrant was surgically excised, and the remaining quadrants were observed for any changes. The gingival overgrowths were excised using a 15 blade, and debris/plaque was removed with Gracey curettes. RESULTS: Although full-mouth exodontia was performed, the patient unfortunately suffered with recurrences in GO. These results are suggestive of idiopathic causes of GO. CONCLUSION: Careful examination, physician referrals, and biopsy to rule out any specific anomalies and to assist in proper diagnosis are followed by sequential management of the case results in productive outcomes.

RESUMEN

OBJECTIVE: The objective of this review was to investigate the epidemiological characteristics of maxillofacial fractures (MFFs), to establish the prevalence of MFFs, and to recognise the major causative factors in both males and females in the Middle East and North Africa (MENA) region. STUDY DESIGN: The protocol of this systematic reviews was established according to the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols (PRISMA-P); the following databases were searched: PubMed/Medline, Scopus, Google Scholar and Web of Science. We used STROBE checklist to assess the risk of bias in all identified studies, 37 studies fulfilled the eligibility criteria, and hence were selected for analysis. RESULTS: A total of 27,994 patients (22,965 males and 5,129 females) ranging from 0 to 97 years who experienced maxillofacial injuries during the study period were entered into this review. Road traffic accidents (RTAs) were the most common cause of MFF followed by falls. The mandible was the most common site of injury. In the MENA region, males outnumbered females in terms of maxillofacial injuries with a ratio of 4.5:1. CONCLUSION: Maxillofacial fractures are highly prevalent in the MENA region, and they are mainly caused by RTAs, especially among young males. Therefore, the concerned authorities need to employ and implement stricter traffic rules in order to minimise the risk of maxillofacial injuries and their subsequent increased morbidity and mortality rates.

RESUMEN

PURPOSE: The objective of this review was to determine the prevalence, major causative factors and the most common sites of Maxillofacial Trauma in the Gulf Cooperation Council (GCC) Countries. METHODS: All articles that were published in the English language in the databases such as Google Scholar, EBSCO, PubMed, NCBI, Medline, COCHRANE, ELSEVIER and SCOPUS were reviewed for MFT from GCC during the last 23 years. RESULTS: A total of 19,151 patients (16,567 males and 2584 females) (86-14%) with an age range between 0 and 97 years were included in the study. In all of the Gulf countries males outnumber females in terms of maxillofacial injuries with a ratio of 6.4:1. The mandible was the most common site of trauma followed by the maxilla. Road Traffic Accidents (RTA) was the most common cause of injury in the GCC followed by falls. CONCLUSION: Maxillofacial injuries are highly prevalent, distributed among the Gulf countries, and is mainly caused by RTAs especially among males who are highly prone to MFT in the gulf. The reasons are due to lack of road safety culture and weak enactment of traffic legislation, other possible factors include intrinsic car safety features, high speed driving and the amount/use of highways in these societies.

RESUMEN

OBJECTIVES: Identify specific maxillofacial trauma patterns associated with cervical spine injuries. METHODS: The protocol was developed according to (PRISMA-P) and was admitted to PROSPERO under accreditation code #CRD42020177816. Furthermore, the reporting of the present SR was conducted based on the PRISMA checklist. RESULTS: Of the 1,407,750 patients recorded, a total of 115,997 patients (12.13%) had MFF with an associated CSI with a gender proportion (M:F) of 3.63:1 respectively. Motor vehicle accident was the most common cause of the combined Maxillofacial Trauma (MFT) and CSI. The most common CSI location was at the C2, followed by the C5 cervical spines. The most common location of a maxillofacial fracture resulting in a CSI was the mandible. CONCLUSION: The incidence of the association of CSIs with MFT has been low (12.13%). Nevertheless, in cases of an isolated mandibular trauma due to a severe blow presenting with a low Glasgow Coma Scale, maxillofacial surgeons should be at a high alert of an associated CSI.
