Abstract:
Improper and inadequate treatment can lead to oro-antral communication and fistula. Certain surgical procedure during operation in posterior maxilla can lead to communication between oral cavity and sinus. In children and adolescents, the risk of oro-antral communication is less, due to smaller volume of the maxillary sinus defect smaller than 2 mm that would adequately heal without any intervention, but larger communications more than 2 mm would require immediate attention from surgeon and treatment should be done as soon possible in order to avoid further complications, infection and patient's discomfort.
