An irregular and diffuse foreign body was seen inside the maxillary sinus. Pre-surgical preparation: washes were performed through the fistula. Under general anesthesia, surgery was performed for the removal of the foreign body and plastic closure of the communication, using the palatal pocket technique. Resultsand conclusion: This technique ensured a tight closure of the communication and prevented reopening of the lesion. This was confirmed during postoperative controls
