Background

Mr Trinidade graduated from the University of the West Indies and has undertaken subspecialist training in Otology & Implantation at Addenbrooke’s Hospital, Cambridge and the University of Arkansas for Medical Sciences in Little Rock, USA. He is a board member of the Prosper Ménière Society which focuses on research devoted to the inner ear and is also a member of the International Otology Outcomes Group.

Mr Trinidade has over 70 scientific peer-reviewed publications and is the author of chapters in surgical textbooks. His current research interests include mastoid obliteration techniques and persistent postural-perceptual dizziness.

He is a dedicated educator with a postgraduate diploma in medical education from the University of Dundee and has also published his own series of textbooks for medical students entitled Fast Track Surgery.

Research interests

  • The pathophysiology and management of persistent postural-perceptual dizziness (PPPD).
  • Obliteration techniques for the management of troublesome mastoid cavities.
  • Hybrid surgical techniques for the management of cholesteatoma.
  • Novel therapies in the management of vestibular migraine.

The ideal surgical management of cholesteatoma remains a contentious issue with new techniques being developed all the time. Some techniques, while effective in treating the cholesteatoma, result in chronic problematic sequalae centred around the creation of a mastoid cavity. Research into innovative hybrid techniques to give the benefit of open cavity techniques while preventing the sequalae, and to deal with already created troublesome cavities will help in better overall patient outcomes.

Vestibular migraine and PPPD remain difficult causes of chronic dizziness to manage. Research into predictors of their onset may lead to prevention and novel therapies can help current sufferers.

Areas of research supervision

  • Supervision of ENT-related research projects by medical students.
  • Supervision of ENT-related research projects by ENT trainees.

Teaching

Mr Trinidade gives regular undergraduate ENT teaching and is involved in curriculum development at ARU School of Medicine where he is a Lecturer. He is also the lead co-ordinator of the ARU Postgraduate ENT Cadaveric Dissection Course series.
