Orofacial cleft (OC) is a group of heterogeneous congenital abnormalities affecting the orofacial region. All over the world, several studies have been conducted on OC. This study aims to analyze OC research outputs in Nigeria. A SCOPUS-based bibliometric analysis of OC research outputs in Nigeria was done. A total of 130 outputs, of which 90% were articles, published within a 5-2-year (1970-2022) interval were identified. These publications had a total of 1,145 citations with a h-index of 19. There was skewedness in the geopolitical distribution and ownership of Nigerian institutions engaged in OC research; the majority of which were owned by the federal government and situated in the southern parts of Nigeria. The University of Lagos was the Nigerian institution with the highest frequency ( = 52) of outputs on OC research. Adeyemo WL was the Nigerian researcher with the highest: number of publications on OC ( = 46), h-index ( = 11) and citations on OC publications ( = 474). Half of the top ten overseas institutions having researchers collaborating with OC researchers in Nigerian institutions were based in the USA. All the institutions funding OC research in Nigeria were foreign and predominantly in the USA. The majority of the 10 most-cited OC outputs from Nigerian institutions were first authored by foreign researchers. There is a need to locally strengthen OC research capacity in Nigeria, especially in the area of funding, and institutional strengthening.
口腔颌面裂（OC）是一组影响口腔颌面区域的异质性先天性异常。在全球范围内，已经针对OC开展了多项研究。本研究旨在分析尼日利亚的OC研究成果。对尼日利亚OC研究成果进行了基于Scopus的文献计量分析。共识别出130项成果，其中90%为文章，发表于1970年至2022年的52年时间间隔内。这些出版物共有1145次引用，h指数为19。参与OC研究的尼日利亚机构在地理政治分布和所有权方面存在不均衡；其中大多数由联邦政府所有，位于尼日利亚南部。拉各斯大学是尼日利亚在OC研究方面产出频率最高（=52）的机构。阿德耶莫·WL是尼日利亚在OC研究方面发表论文数量最多（=46）、h指数最高（=11）以及OC出版物引用次数最多（=474）的研究人员。与尼日利亚机构的OC研究人员合作的海外机构中，排名前十的机构有一半位于美国。在尼日利亚资助OC研究的所有机构均为外国机构，且主要来自美国。尼日利亚机构被引用次数最多的10项OC成果中，大多数第一作者为外国研究人员。有必要在当地加强尼日利亚的OC研究能力，特别是在资金和机构建设方面。
