本研究调查了自 1962 年该专业成立以来尼日利亚神经外科研究的范围、趋势和挑战。对尼日利亚神经外科文献进行了文献计量回顾。提取的变量包括出版年份和期刊、文章主题、文章类型、研究类型、研究设计、文章重点领域和局限性。对所有变量进行描述性和定量分析。研究出版物的趋势描述了三个时期——开拓期（1962-1981）、衰退期（1982-2001）和复兴期（2002-2021）。在1023篇纳入文章中，10.0%发表在开拓期，9.2%发表在开创期。衰退期为80.8%，复苏期为80.8%。论文主要发表在《世界神经外科》（4.5%）和《尼日利亚临床实践杂志》（4.0%）上。 4618 名作者中，79.9% 来自尼日利亚机构。 86.3% 的文章涉及临床研究，主要关注服务提供和流行病学（89.9%）。最突出的主题是创伤性脑损伤（25.8%）和中枢神经系统恶性肿瘤（21.4%）。只有 4.4% 的出版物获得了资助，大部分来自美国机构 (31.7%)。神经外科研究的障碍包括缺乏临床数据库 (18.0%)、疾病负担增加 (12.5%) 和诊断挑战 (12.4%)。由于培训、劳动力和基础设施的改善，尼日利亚的神经外科研究持续增长。通过建立研究数据库、制定循证管理指南以及增加研究培训、资金和机会来应对主要挑战，可以提高尼日利亚的研究能力。版权所有 © 2023。由爱思唯尔公司出版。

This study investigates the scope, trends, and challenges of neurosurgical research in Nigeria since inception of the specialty in 1962.A bibliometric review of the neurosurgical literature from Nigeria was done. Variables extracted included year and journal of publication, article topic, article type, research type, study design, article focus area, and limitations. Descriptive and quantitative analyses were performed for all variables. Trends of research publications were described in three periods - pioneering (1962-1981), recession (1982-2001), and resurgent (2002-2021).Of the 1023 included articles, 10.0% were published in the pioneering period, 9.2% in the recession period, and 80.8% in the resurgent period. Papers were predominantly published in World Neurosurgery (4.5%) and Nigerian Journal of Clinical Practice ( 4.0%). 79.9% of the 4618 authors were from Nigerian institutions. 86.3% of the articles covered clinical research and were mainly focused on service delivery and epidemiology (89.9%). The most prominent topics were traumatic brain injury (25.8%) and CNS malignancy (21.4%). Only 4.4% of the publications received funding, mostly from agencies in the US (31.7%). Barriers to neurosurgical research included lack of clinical databases (18.0%), increasing burden of disease (12.5%), and diagnostic challenges (12.4%).Neurosurgical research in Nigeria continues to grow due to increased training, workforce, and infrastructural improvements. Addressing the major challenges through establishment of research databases, development of evidence-based management guidelines, and increasing research training, funding and opportunities can increase research capacity in Nigeria.Copyright © 2023.
