text: An oronasal fistula (ONF) is a small hole in the upper jaw bone (maxilla) which creates an abnormal communication path between the oral cavity and the nasal cavity and allows food, saliva and water to enter the respiratory tract, leading to chronic rhinitis (irritation to the nose), sinus inflammation and aspiration pneumonia.
