HPCSA Otorhinolaryngology Registrar Research Requirements

All HPCSA otorhinolaryngology registrars must complete a research project during their 4-year specialist training programme. The research protocol should be developed early in training, approved by a supervisor, submitted for institutional ethics review before data collection, and aligned with clinically relevant ENT and head-neck priorities in South Africa.

Given South Africa’s ENT priorities – including chronic otitis media, preventable hearing loss, paediatric ENT disease, allergic rhinitis, chronic sinusitis, head and neck cancer, thyroid disease, HIV-related ENT conditions, airway emergencies, trauma, and limited access to specialist ENT services – otorhinolaryngology research topics should be practical, ethically sound, and relevant to real-world service delivery while maintaining strong academic and methodological standards.
