Today, ASCENT ENT is served by 6 doctors covering the main subspecialties in ENT – Otology, Rhinology, Laryngology, Sleep Medicine & Surgery, and Paediatric ENT. Each of our doctors has undergone internationally-recognised fellowship training in their respective fields after completing ENT specialist training in Singapore.
