The Oro-nasal-fistula is a complication of maxillofacial trauma, even when the trauma is managed with proper protocol. The palatal bone is relatively thin and it has weak bony support from the adjacent bone, which leads to increase chances of postoperative complications such as fistula formation. The management of palatal fistula depends on the size, site, and mode of presentation. The two flap palatoplasty technique is used in cleft patients for decades. This is simple, effective with good healing of raw site and there is less chance of recurrence. Palatal fistula can be treated by many methods, but only a few articles are published in which fistula as a sequel to trauma is described. Here the authors present 4 cases of Oro-nasal-fistula, which were successfully treated by two flap palatoplasty techniques. The authors also briefly review every aspect and implication of this technique.
