Greene MW, King RC, Alley RS. Management of an oroantral fistula in a patient with Wilson s disease case report and review of the literature. Oral Surg Oral Med Oral Pathol 1988 66(3) 293-6. 

An antrostomy with oroantral fistula, a connection between the oral cavity and the maxillary sinus, can be identified through the HR vertical reconstructions of the maxillary sinus floor (Fig. 13.17B). Prompt telephone notification of the dentist or oral surgeon and documentation in the report before discussion with the patient are essential in cases of iatrogenic complication. Optimal information on the operation is a condition for the correct interpretation of these critical findings.
