Rhinology (sinus surgery) research
Failure of endoscopic sinus surgery to improve patients symptoms can be due to adhesions and lateralisation of the middle turbinate. Adhesions prevent sinus drainage and nasal irrigations or steroid sprays to enter the sinuses. Associate Professor Eng Ooi uses a silastic sinus stent in some patients undergoing endoscopic sinus surgery to prevent adhesions and reduce middle turbinate lateralisation and reduced revision surgery rates. He demonstrated its effectiveness in a randomised controlled trial (level 1 evidence based medicine) in ENT patients undergoing endoscopic sinus surgery (FESS) at Flinders Medical Centre (FMC)
Head and Neck Cancer Research
Tonsil (oropharyngeal) cancer is becoming the most common type of cancer in the head and neck region. It is more common in males and is associated with the Human Papilloma Virus (HPV). Smoking continues to be a risk factor for developing head and neck cancer but HPV is emerging as a strong risk factor especially with tonsil cancer. Tonsil, Head and Neck cancer is treatable if detected early. Associate Professor Eng Ooi is a leading member of the Flinders Multi-disciplinary Head and Neck Cancer team. He maintains an active up to date involvement with the latest treatment options and is leading several research projects to improve care for head and neck cancer patients. This include developing blood and breath tests to detect tonsil cancer (currently none exist) and improving swallowing difficulties (dysphagia) in patients.
Associate Professor Eng Ooi is leading research into new techniques to perform tonsillectomy to minimise blood loss, improve recovery and patients Quality of Life. He regularly conducts quality audit reviews to ensure his techniques are improving patient outcomes.
Associate Professor Ooi is an academic ENT surgeon scientist who believes in providing the best care for his patients based on the latest research evidence, and personal clinical experience. He runs several major research projects through his private practice, Flinders Medical Centre, and Flinders University. His PhD in research and role as Head of ENT at Flinders Medical Centre strengthens the care he offers patients in his private practice.
He has research interests in chronic sinusitis, advanced endoscopic sinus surgery, developing a blood test to detect tonsil, head and neck cancer, NHMRC trial of UPPP and Coblation tongue channeling for OSA, use of lasers and surgical simulation to improve surgical training.
