Stephen Tjoa is a researcher at Erasmus MC specializing in Oral and Maxillofacial Surgery. His work focuses on craniofacial disorders, orthodontic interventions, and surgical protocols for congenital anomalies like facial dysostosis syndromes and cleft lip/palate. He collaborates extensively across Europe in multidisciplinary teams.

Research interests:

• Development of European registries for craniofacial conditions
• Comparative analysis of surgical protocols for cleft lip and palate
• Orthodontic aligner therapy in neurodiverse populations
• Three-dimensional imaging of dento-skeletal surgical outcomes

Key trends in research output:
Recent publications highlight systematic reviews on cleft palate treatments, clinical consensus statements for dysostosis syndromes, and applications of 3D imaging in maxillofacial surgery. His work spans both technical surgical evaluations and collaborative guideline development.
