About Dr Sebastian Ranguis
Experienced Adult & Paediatric ENT Specialist
“There are so many reasons I was drawn to ENT – the mix of medical and surgical conditions, the complex head and neck anatomy – but most of all being able to help patients of all ages achieve the best possible outcomes. Focusing on paediatric ENT allows me to help vulnerable children and their families. These are very young children, often newborns and infants suffering with airway and head and neck disorders in the smallest packages. As a surgeon, I thrive in stressful environments and the challenging nature of paediatric airway surgery is a natural choice for me. I treat all my patients as if they were members of my own family.”
