Oral and Maxillofacial Surgery: Availability of Specialist Training and Different Training Pathways across Africa

Background

Oral and maxillofacial surgery (OMFS) is the surgical specialty concerned with the treatment of a broad range of conditions that affect the head, face, mouth, neck, and jaw. In Africa, there is a paucity of information about the specialist training available to aspiring African Oral and Maxillofacial Surgeons.

Objective

This paper aimed at shedding light on the available OMFS specialist training programmes and training pathways across Africa.

Materials and Methods

The authors searched on PubMed, AJOL, and Google Scholar using the keywords "Africa," "Oral and Maxillofacial Surgery," "Residency," "Postgraduate," and "Education" and the individual African countries in English and official languages from inception till July 11, 2022. The authors utilised a questionnaire to interview native oral and maxillofacial surgeons and dentists in African countries where there were no published data on OMFS specialist training.

Results

A total of 21 (38.8%) African countries had OMFS specialist training programmes (n = 69). The duration of training varies between 2 and 7 years. The number of training programmes per country ranges between one and thirteen. Countries with the most training programmes for OMFS in Africa are Nigeria, Egypt, Sudan, and Algeria. Northern Africa and Central Africa had the most and least numbers of specialist training programmes in OMFS, respectively.

Conclusion

There remains a disparity in the number of specialist training programmes available to aspiring African Oral and Maxillofacial Surgeons as compared with other parts of the world. This paper is intended to function both as a means of advocacy to increase funding and resources in support of the infrastructure and development of facilities for African OMFS specialist training programmes and also serve as a valuable reference for future research in OMFS.

The prognostic utility of temporalis muscle thickness measured on magnetic resonance scans in patients with intra-axial malignant brain tumours: A systematic review and meta-analysis

Introduction

Sarcopenia is associated with worsened outcomes in solid cancers. Temporalis muscle thickness (TMT) has emerged as a measure of sarcopenia. Hence, this study aims to evaluate the relationship between TMT and outcome measures in patients with malignant intra-axial neoplasms.

Method

We searched Medline, Embase, Scopus and Cochrane databases for relevant studies. Event ratios with 95% confidence intervals (CI) were analysed using the RevMan 5.4 software. Where meta-analysis was impossible, vote counting was used to determine the effect of TMT on outcomes. The GRADE framework was used to determine the certainty of the evidence.

Results

Four outcomes were reported for three conditions across 17 studies involving 4430 patients. Glioblastoma: thicker TMT was protective for overall survival (OS) (HR 0.59; 95% CI 0.46-0.76) (GRADE low), progression free survival (PFS) (HR 0.40; 95% CI 0.26-0.62) (GRADE high), and early discontinuation of treatment (OR 0.408; 95% CI 0.168-0.989) (GRADE high); no association with complications (HR 0.82; 95% CI 0.60-1.10) (GRADE low). Brain Metastases: thicker TMT was protective for OS (HR 0.73; 95% CI 0.67-0.78) (GRADE moderate); no association with PFS (GRADE low). Primary CNS Lymphoma: TMT was protective for overall survival (HR 0.34; 95% CI 0.19-0.60) (GRADE moderate) and progression free survival (HR 0.23; 95% CI 0.09-0.56) (GRADE high).

Conclusion

TMT has significant prognostic potential in intra-axial malignant neoplasms, showing a moderate to high certainty for its association with outcomes following GRADE evaluation. This will enable shared decision making between patients and clinicians.

The prognostic utility of neutrophil-lymphocyte ratio in spinal surgery: A systematic review and meta-analysis

PURPOSE

Neutrophil-lymphocyte ratio (NLR) is reportedly an effective prognostic tool across various medical and surgical fields, but its value in spinal surgery is unestablished. We aim to investigate the relationship between elevated baseline/postoperative NLR and patient outcomes in spinal surgery.

MATERIALS AND METHODS

We performed a systematic search in PubMed, EMBASE, and SCOPUS databases for studies investigating the prognostic value of NLR in spine patients.Odds ratios (ORs) and hazard ratios (HRs) with 95% confidence intervals (CIs) were analysed on the RevMan 5.4 software. Where meta-analysis was not possible, we vote-counted the direction of the effect of elevated NLR. The GRADE framework for prognostic factor research was utilised to assess the certainty of the evidence for each outcome measure.

RESULTS

Five outcome measures (overall survival, mortality, disease-free survival, functional recovery and complications) were assessed across 16 studies involving 5471 patients. Elevated baseline NLR was associated with reduced overall survival (HR: 1.63, 95 % CI: 1.05 - 2.54) (GRADE: low) and worsened functional recovery (OR: 0.93, 95 % CI: 0.87 - 0.98) (GRADE: low). There was no association between baseline NLR and disease-free survival (HR: 2.42, 95 % CI: 0.49 - 11.83) (GRADE: very low) or mortality (OR: 1.39, 95 % CI: 0.41 - 4.75) (GRADE: very low). Elevated NLR levels measured on days 3-4 and days 6-7 postoperatively, but not NLR measured at baseline or on days 1-2 postoperatively, were associated with greater risks of complications (GRADE: low).

CONCLUSIONS

NLR is an objective tool with the potential to identify the patients that would benefit from surgery and facilitate shared decision-making.

Trends in research grant applications and outcomes among medical students in the United Kingdom: a national self-reported cross-sectional survey

BACKGROUND

Research funding disparities contribute to clinical academic workforce inequalities. Hence, our study explores the association between student demographics and research grant application rates and outcomes among UK medical students.

METHODS

This is a national multicentre cross-sectional survey of UK medical students in the 2020-21 academic year. Multiple zero-inflated negative binomial regression and generalized linear model (binomial distribution; logit link) were utilized to investigate the association between student demographics, number of grant applications submitted, and successful grant applications (yes or no). P-values less than a Bonferroni-corrected significance level of 0.05/36 = 0.0014 were considered to be statistically significant.

RESULTS

A total of 1528 students participated from 36 medical schools. One hundred fifty-one respondents (9.9%) had applied for research grants. Black students submitted applications 2.90 times more often than white students [Incident rate ratio (IRR): 2.90, 95% confidence interval (CI): 1.37-6.16], with no ethnic disparity in the odds of successful applications. Gender did not influence application rates significantly (P = .248), but women were 4.61 times more likely to secure a grant than men [odds ratio: 4.61, 95% CI: 2.04-10.4]. Being a PubMed-indexed author was associated with increased grant application submission rates [IRR: 3.61, 95% CI: 2.20- 5.92] while conducting more research was associated with greater odds of securing a grant [odds ratio: 1.42, 95% CI: 1.17- 1.73].

CONCLUSION

Although black students submitted more applications, ethnicity did not influence success rates. Gender did not influence application rates, but women were more successful. These findings underscore the need for strategies supporting women and underrepresented students for continued academic achievement after graduation.

KEY MESSAGES

What is already known on this topic Research funding for post-PhD researchers is believed to be a major driver of gender and ethnic inequalities in the clinical academic workforce.Students who receive research grants are more likely to receive postgraduate research grants.What this study adds Black students applied for more research grants than white students, but there were no ethnic differences in the odds of securing a grant.There were no gender differences in the research grant application rates. However, female students had greater odds of securing research grants compared to male students.How this study might affect research, practice or policy Medical schools should incorporate grant writing skills into the undergraduate research curriculum. Also, to sustain women's academic success post medical school, the NIHR and affiliates should provide research award extensions and childcare support for women when required.

Predictors of self-reported research engagement and academic-career interest amongst medical students in the United Kingdom: a national cross-sectional survey

BACKGROUND

We hypothesised that the gender/ethnic disparities and reductions in the UK academic-clinician workforce stem from research experience in medical school. This study investigated the factors influencing research engagement and academic-career interests among UK medical students.

METHODS

Using a 42-item online questionnaire, a national multicentre cross-sectional survey of UK medical students was conducted over 9 weeks in the 2020/21 academic year. Multiple binary logistic and zero-inflated negative binomial regressions were used to evaluate associations between the predictor variables and research engagement (yes/no), number of research projects conducted, and academic-career interest (yes/no). P < 0.05 was considered statistically significant.

RESULTS

In total, 1573 students participated from 36 medical schools. No ethnic/gender differences in research engagement were observed. However, compared to men, women had a 31% decrease in the odds of being interested in an academic-clinician career [odds ratio (OR): 0.69; 95% confidence interval (CI): 0.52, 0.92]. Positive predictors of interest in academia were being a PubMed-indexed author (OR: 2.19; 95% CI: 1.38, 3.47) and having at least one national/international presentation (OR: 1.40; 95% CI: 1.04, 1.88). Career progression was the primary motivating factor (67.1%) for pursuing research, whereas limited awareness of opportunities (68.0%) and time constraints (67.5%) were the most common barriers.

CONCLUSION

There were no ethnic differences in research engagement or academic-career intent. Although there were no gender differences in research engagement, female students were less likely to be interested in an academic career. This could be tackled by providing targeted opportunities to increase research productivity and self-efficacy in medical schools. Key messages: What is already known on this topic: There has been a decline in the number of academic clinicians, with a disproportionate gender and ethnic representation in the academic workforce. Engaging medical students in research activities during their medical training could mitigate the declining number of academic clinicians. Differential attainment occurs in medical school and persists after graduation. What this study adds: Although there were no gender/ethnic differences in research engagement amongst UK medical students, our study suggests that female students were less likely to be interested in pursuing an academic career. Time constraints, a lack of awareness of opportunities, and difficulty in finding research supervisors/mentors were the most common barriers to research engagement, whereas PubMed-indexed authorship was the strongest positive predictor of interest in an academic career. How this study might affect research, practice, or policy: Medical schools should facilitate the selection of good-quality research mentors that would provide adequate support to ensure that their students' works are published in peer-reviewed journals. Medical schools should employ local research officers to increase students' awareness of research opportunities.

Prognostic Factors in Patients with Metastatic Spinal Cord Compression Secondary to Lung Cancer-A Retrospective UK Single-Centre Study

PURPOSE

Metastatic spinal cord compression (MSCC) is a severe complication of cancer that can lead to irreversible neurological impairment, necessitating prompt recognition and intervention. This retrospective, single-centre study aimed to determine the prognostic factors and survival rates among patients presenting with MSCC secondary to lung cancer.

METHODS AND MATERIALS

We identified 74 patients with epidural metastases-related spinal cord compression and a history of lung cancer through the electronic database of Medway Maritime Hospital in the United Kingdom (UK), spanning the period from April 2016 to September 2021. Among them, 39 were below 55 years old, while 35 were aged 55 years or older; 24 patients were diagnosed with small cell lung cancer (SCLC), and 50 patients had non-small cell lung cancer (NSCLC).

RESULTS

The median overall survival (OS) was 5.5 months, with 52 out of 74 patients dying within 6 months of diagnosis with MSCC. For the entire cohort, the statistically significant variables on multi-variate analysis were cancer type (NSCLC had improved OS), the number of involved vertebrae (one to two vertebrae involvement had improved OS), and the time taken to develop motor deficits (≤10 days to develop motor deficits had worsened OS). For the NSCLC cohort, the statistically significant variables on multivariate analysis were molecular alterations (patients with epidermal growth factor receptor (EGFR) mutation), pre-treatment ambulatory status, Eastern Cooperative Oncology Group (ECOG) performance status, and the time taken to develop motor deficits.

CONCLUSIONS

Within the entire cohort, patients diagnosed with NSCLC and spinal metastases affecting one to two vertebrae exhibited enhanced OS. Within the NSCLC subgroup, those with EGFR mutations who were ambulatory and possessed an ECOG performance status of 1-2 demonstrated improved OS. In both the entire cohort and the NSCLC subgroup, the development of motor deficits within a period of ≤10 days was associated with poor OS.

The impact of phosphodiesterase inhibition on neurobehavioral outcomes in preclinical models of traumatic and non-traumatic spinal cord injury: a systematic review

Study design

Systematic review.

Objective

The objective of this study was to evaluate the impact of phosphodiesterase (PDE) inhibitors on neurobehavioral outcomes in preclinical models of traumatic and non-traumatic spinal cord injury (SCI).

Methods

A systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines and was registered with PROSPERO (CRD42019150639). Searches were performed in MEDLINE and Embase. Studies were included if they evaluated the impact of PDE inhibitors on neurobehavioral outcomes in preclinical models of traumatic or non-traumatic SCI. Data were extracted from relevant studies, including sample characteristics, injury model, and neurobehavioral assessment and outcomes. Risk of bias was assessed using the SYRCLE checklist.

Results

The search yielded a total of 1,679 studies, of which 22 met inclusion criteria. Sample sizes ranged from 11 to 144 animals. PDE inhibitors used include rolipram (n = 16), cilostazol (n = 4), roflumilast (n = 1), and PDE4-I (n = 1). The injury models used were traumatic SCI (n = 18), spinal cord ischemia (n = 3), and degenerative cervical myelopathy (n = 1). The most commonly assessed outcome measures were Basso, Beattie, Bresnahan (BBB) locomotor score (n = 13), and grid walking (n = 7). Of the 22 papers that met the final inclusion criteria, 12 showed a significant improvement in neurobehavioral outcomes following the use of PDE inhibitors, four papers had mixed findings and six found PDE inhibitors to be ineffective in improving neurobehavioral recovery following an SCI. Notably, these findings were broadly consistent across different PDE inhibitors and spinal cord injury models.

Conclusion

In preclinical models of traumatic and non-traumatic SCI, the administration of PDE inhibitors appeared to be associated with statistically significant improvements in neurobehavioral outcomes in a majority of included studies. However, the evidence was inconsistent with a high risk of bias. This review provides a foundation to aid the interpretation of subsequent clinical trials of PDE inhibitors in spinal cord injury.

Predictors of self-reported research productivity amongst medical students in the United Kingdom: a national cross-sectional survey

BACKGROUND

The number of academic clinicians in the UK is declining and there are demographic inequalities in the clinical-academic workforce. Increased research productivity by medical students is believed to reduce future attrition in the clinical-academic workforce. Thus, this study investigated the association between student demographics and research productivity amongst UK medical students.

METHODS

This is a national multicentre cross-sectional study of UK medical students in the 2020/21 academic year. We appointed one student representative per medical school, and they disseminated a 42-item online questionnaire over nine weeks, through departmental emails and social media advertisements. The outcome measures were: (i) publications (yes/no) (ii) number of publications (iii) number of first-authored publications (iv) abstract presentation (yes/no). We utilised multiple logistic and zero-inflated Poisson regression analyses to test for associations between the outcome measures and predictor variables at a 5% significance level.

RESULTS

There are 41 medical schools in the UK. We received 1573 responses from 36 UK medical schools. We failed to recruit student representatives from three newly formed medical schools, whilst two medical schools prohibited us from sending the survey to their students. Women had lower odds of having a publication (OR: 0.53, 95% CI: 0.33-0.85) and on average had fewer first-author publications than men (IRR: 0.57, 95% CI: 0.37-0.89). Compared to white students, mixed-ethnicity students had greater odds of having a publication (OR: 3.06, 95% CI: 1.67-5.59), an abstract presentation (OR: 2.12, 95% CI: 1.37-3.26), and on average had a greater number of publications (IRR: 1.87, 95% CI: 1.02-3.43). On average, students who attended independent UK secondary schools had a higher rate of first-author publications compared to those that attended state secondary schools (IRR: 1.97, 95% CI: 1.23-3.15).

CONCLUSION

Our data suggest that there are gender, ethnic and socioeconomic inequalities in research productivity among UK medical students. To tackle this, and potentially improve diversity in clinical academia, we recommend that medical schools should facilitate targeted high quality research mentorship, funding and training, especially for under-represented-in-medicine students.

Predictors of self-reported research self-efficacy and perception of research amongst medical students in the United Kingdom: a national cross-sectional survey

PURPOSE

There has been a decline in the number of academic clinicians in the UK, and there are ethnic/gender disparities in the academic workforce. Higher research self-efficacy (RSE) and a positive perception of research (PoR) amongst students are associated with a higher motivation to engage in academic medicine. Hence, this study aimed to determine the factors that influence RSE and PoR amongst UK medical students.

METHODS

This is a multicentre cross-sectional survey of medical students in 36 UK medical schools in the 2020/21 academic year. Multiple linear regression was used to investigate the association between students' demographics and RSE/PoR. P-values less than a Bonferroni-corrected significance level of .05/28 = .0018 were considered statistically significant.

RESULTS

In total, 1573 individuals participated from 36 medical schools. There were no ethnic differences in PoR or RSE scores. Although there were no gender differences in PoR, female students had lower RSE scores than male students (adjusted β = -1.75; 95% CI: -2.62, -0.89). Research experience before medical school (adjusted β = 3.02; 95% CI: 2.11, 3.93), being in the clinical training phase (adjusted β = 1.99; 95% CI: 1.09, 2.90), and completing a degree before medical school (adjusted β = 3.66; 95% CI: 2.23, 5.09) were associated with higher RSE.

CONCLUSION

There were no associations between the predictor variables and PoR. Female students had lower self-reported RSE scores. Future studies should investigate the role of targeted research mentorship in improving RSE amongst female medical students.

Does Preoperative Neutrophil-Lymphocyte Ratio Predict Patient-Reported Pain and Functional Outcomes at 12 Months After Lumbar Fusion?

BACKGROUND

Preoperative neutrophil-lymphocyte ratio (NLR) has been described in various fields to predict pain outcomes, but its prognostic utility for pain/functional outcomes after spine surgery is unclear.

OBJECTIVE

To determine the relationship between preoperative NLR and pain/functional outcomes at 12 months after lumbar fusion.

METHODS

We performed a single-center retrospective study of 53 patients who underwent lumbar fusion and collected demographic data including age, sex, body mass index, smoking status, spinal levels operated, and preoperative NLR. Visual analog scale (VAS) for back and leg pain and Oswestry Disability Index (ODI) at baseline and 12 months after lumbar fusion were also collected. The outcome measures were the occurrence of a clinically important improvement in VAS and ODI scores at 12 months. Binary logistic regression was used to estimate the associations of demographic factors and NLR with improvement in VAS and ODI scores. A P value of <0.05 was considered statistically significant.

RESULTS

There were no statistically significant associations between preoperative NLR and improvement in VAS or ODI scores. A unit increase in baseline VAS back pain score was associated with a 56% increase in the odds of improvement in back pain (OR: 1.56, 95% CI: 1.04-2.35, P = 0.03). Compared to male patients, female patients had 12 times greater odds of an improvement in leg pain (OR: 12.0, 95% CI: 1.3-110, P = 0.03).

CONCLUSION

Preoperative NLR does not predict patient-reported pain/functional outcomes at 12 months after lumbar fusion. Large-scale prospective multicenter studies are warranted to confirm our findings.

Preoperative lymphocyte percentage and neutrophil-lymphocyte ratio are useful predictors of 30-day postoperative complications after lumbar fusion

Background:

Lymphocyte percentage/count, platelet-lymphocyte ratio (PLR), and neutrophil-lymphocyte ratio (NLR) have shown prognostic significance in patients with cancer, stroke, and following cardiac surgery. However, the utility of these blood parameters for assessing the 30-day postoperative risk for lumbar fusion complications has not been established.

Methods:

In this single-center-single-surgeon retrospective series, 77 consecutive patients underwent one- or two-level lumbar fusion. Lymphocyte percentage/count, PLR, and NLR were investigated as predictors of 30-day postoperative complications.

Results:

Ten of 77 patients had postoperative complications. A unit increase in NLR and lymphocyte percentage was significantly associated with a 23% increase and 7% decrease, respectively, in the odds of a complication occurring. Preoperative NLR ≥ 2.32 and lymphocyte percentage ≤ 29.5% significantly discriminated between the “complication” and “no-complication” groups.

Conclusion:

Patients with a preoperative lymphocyte percentage of ≤29.5% and/or NLR ≥2.32 should be closely monitored as high-risk groups susceptible to 30-day postoperative complications after lumbar fusion.

Systematic review of the impact of cannabinoids on neurobehavioral outcomes in preclinical models of traumatic and nontraumatic spinal cord injury

STUDY DESIGN

Systematic review.

OBJECTIVES

To evaluate the impact of cannabinoids on neurobehavioral outcomes in preclinical models of nontraumatic and traumatic spinal cord injury (SCI), with the aim of determining suitability for clinical trials involving SCI patients.

METHODS

A systematic search was performed in MEDLINE and Embase databases, following registration with PROPSERO (CRD42019149671). Studies evaluating the impact of cannabinoids (agonists or antagonists) on neurobehavioral outcomes in preclinical models of nontraumatic and traumatic SCI were included. Data extracted from relevant studies, included sample characteristics, injury model, neurobehavioural outcomes assessed and study results. PRISMA guidelines were followed and the SYRCLE checklist was used to assess risk of bias.

RESULTS

The search returned 8714 studies, 19 of which met our inclusion criteria. Sample sizes ranged from 23 to 390 animals. WIN 55,212-2 (n = 6) and AM 630 (n = 8) were the most used cannabinoid receptor agonist and antagonist respectively. Acute SCI models included traumatic injury (n = 16), ischaemia/reperfusion injury (n = 2), spinal cord cryoinjury (n = 1) and spinal cord ischaemia (n = 1). Assessment tools used assessed locomotor function, pain and anxiety. Cannabinoid receptor agonists resulted in statistically significant improvement in locomotor function in 9 out of 10 studies and pain outcomes in 6 out of 6 studies.

CONCLUSION

Modulation of the endo-cannabinoid system has demonstrated significant improvement in both pain and locomotor function in pre-clinical SCI models; however, the risk of bias is unclear in all studies. These results may help to contextualise future translational clinical trials investigating whether cannabinoids can improve pain and locomotor function in SCI patients.

Traumatic pneumorrhachis: systematic review and an illustrative case

Pneumorrhachis (PR) refers to free air in the spinal canal. We aim to describe a case report and conduct a systematic review focused on the clinical presentation, diagnosis, and management of traumatic PR. We conducted a language-restricted PubMed, SciELO, Scopus, and Ovid database search for traumatic PR cases published till June 2019. Categorical variables were assessed by Fisher's exact test. In addition to our reported index case, there were 82 articles (96 individual cases) eligible for meta-analysis according to our inclusion/exclusion criteria. Eighty per cent of patients had blunt trauma, while 17% had penetrating injuries. Thirty-four per cent of cases were extradural PR, 21% intradural PR, and unreported PR type in 43%. Nine per cent of patients presented with symptoms directly attributed to PR: sensory radiculopathy (2%), motor radiculopathy (1%), and myelopathy (6%). CT had a 100% sensitivity for diagnosing PR, MRI 60%, and plain radiograph 48%. Concurrent injuries reported include pneumocephalus (42%), pneumothorax (36%), spine fracture (27%), skull fracture (27%), pneumomediastinum (24%), and cerebrospinal fluid leak (14%). PR was managed conservatively in every case, with spontaneous resolution in 96% on follow-up (median = 10 days). Prophylactic antibiotics for meningitis were given in 13% PR cases, but there was no association with the incidence of meningitis (overall incidence: 3%; prophylaxis group (0%) vs non-prophylaxis group (4%) (p = 1)). Occasionally, traumatic PR may present with radiculopathy or myelopathy. Traumatic PR is almost always associated with further air distributions and/or underlying injuries. There is insufficient evidence to support the use of prophylactic antibiotic in preventing meningitis in traumatic PR patients.

Scalp Cirsoid Aneurysms: Case Illustration and Systematic Review of Literature

BACKGROUND

Scalp cirsoid aneurysms are rare subcutaneous arteriovenous fistulae affecting the scalp. They can be easily misdiagnosed and mistreated.

OBJECTIVE

To review reported cases of scalp cirsoid aneurysms for their incidence, etiology, clinical presentation, treatment, and outcomes using an illustrative case.

METHODS

We conducted a PUBMED, SCOPUS, OVID SP, SciELO, and INFORMA search using the keywords; “cirsoid,” “aneurysm,” “arteriovenous,” “malformation,” “scalp,” “vascular,” and “fistula.” We identified 74 pertinent papers, reporting 242 cases in addition to our reported index case.

RESULTS

Median age at presentation was 25 yr (range 1-72 yr); male to female ratio was 2.5:1. The most common symptoms were a pulsatile mass (94% of patients), headaches (25%), and tinnitus (20%). The median duration of symptoms was 3 yr (6 d to 31 yr), with 60.2% occurring spontaneously, 32.23% traumatic, and the rest iatrogenic. A total of 58.5% of cases were managed with surgical excision only, 21.6% with endovascular embolization only, and 14.5% with a combination of both methods. The complication rate observed in the endovascular embolization treatment cohort (55.8%) was significantly higher than that observed in the surgical excision only cohort (9.9%) (P &lt; .00001) and in the combined therapy cohort (0%) (P &lt; .00001). There is a low recurrence rate after treatment irrespective of modality: surgical excision only (6.3%), endovascular embolization only (8.3%), and combined therapy (0%).

CONCLUSION

Scalp cirsoid aneurysms are associated with good prognoses when recognized and managed appropriately. We suggest combining surgery with endovascular embolization as the optimum treatment modality.
