Professor Dr. Dr. Chima Oji is a Nigerian-German oral and maxillofacial surgeon, academic, author, and pioneer in surgical techniques for tongue management in orofacial procedures. He is renowned for developing two innovative methods collectively referred to as "Oji's technique" or "The Oji Technique," particularly for tongue reduction and fixation in complex cases.
Early Life and Background
Chima Oji (full title: Prof. Dr. Dr. Chima Oji) is from Ngwo community in Enugu State, Nigeria (Enugu North LGA, often associated with Igbo heritage). He relocated to Germany for higher education and professional training, where he spent much of his career. As a Black African in Germany, he documented experiences of racism ranging from subtle prejudice to severe threats, including death threats, in his autobiographical work.
Education and Qualifications
- MBBS (Medicine), Germany, 1975.
- BDS (Dentistry), Germany, 1980.
- PhD in Medicine (Dr. med.).
- PhD in Dentistry (Dr. med. dent.).
- Fellow of the West African College of Surgeons (FWACS).
His dual doctoral degrees explain the "Dr. Dr." designation common in German academic tradition for holders of two doctorates.
Career and Professional Achievements
Oji specialized in oral and maxillofacial surgery. He served as Head of Department at the Department of Oral and Maxillofacial Surgery, University of Nigeria Teaching Hospital / University of Nigeria, Nsukka (UNN), where he contributed to training and clinical practice. He was appointed Professor of Oral and Maxillofacial Surgery in 2000 and Professor of Homeopathy in 2001 (reflecting interdisciplinary expertise).
Key innovations: - The Oji Technique (for tongue reduction): Described in publications (e.g., 2016 paper on a rare case of trifid tongue, macroglossia, ankyloglossia, and orofacial anomalies). It features a "rocket-like incision" for uniform tongue reduction, achieving functional and aesthetic outcomes in complex congenital cases. - The Oji Spatula (for tongue fixation after total mandibulectomy): A method using a wooden spatula tied horizontally across the mouth to secure the tongue post-surgery, contrasting rigid fixation techniques. Published in 2003 (cited in PubMed/ResearchGate).
He has affiliations with Ebonyi State University (Department of Surgery) and independent research roles, with publications on jaw cysts, oral anomalies, and related topics (12+ papers, 66+ citations noted in academic databases).
Recent Appointments
In July 2025, President Bola Ahmed Tinubu appointed him as a member of the Governing Council (representing South East zone) for the newly established Federal University of Environment and Technology, Koroma/Saakpenwa, Ogoniland (Rivers State, Nigeria). This is part of a 5-member council including representatives from other geopolitical zones, alongside principal officers for the institution focused on environmental and technological studies.
Publications and Authorship
- Unter die Deutschen gefallen: Erfahrungen eines Afrikaners ("Fallen Among the Germans: Experiences of an African," German edition, published 1992/1993 by Peter Hammer Verlag; later editions by Ullstein). An autobiographical account of his life as a Nigerian migrant in Germany, addressing racism, integration challenges, disillusionment, and identity. It has been analyzed in literary studies on Afro-German culture, migration narratives, and postcolonial themes.
Other works include technical papers on oral surgery techniques and cases.
Recognition and Impact
Oji is celebrated in Nigerian media, diaspora communities, and Igbo networks for his contributions to global surgery, academic excellence, and representation of African talent abroad. His techniques remain referenced in orofacial anomaly management. As a dual-qualified professor and council appointee, he exemplifies Nigerian-German academic bridges and advocacy for underrepresented voices.

Exact birth date, family details, or full career chronology remain limited in public sources. The "Oji's technique" refers primarily to his documented innovations in tongue handling/reduction and post-mandibulectomy fixation.
