Transmaxillary approach to the orbital floor has been used successfully to treat the blowout fracture by antral packing to support the orbital floor. However, antral packs are associated with a high incidence of infection and persistent oroantral fistula. A 30-year-old man with a history of the orbitozygomatic complex fracture 8 years ago presented with a persistent facial wound on the right side of the cheek. The patient underwent an exploratory surgery under general anesthesia, and the maxillary sinus was approached through the Caldwell-Luc operation and a long 2-m nasal tampon was found in the sinus. Foreign bodies including gossypibomas are rare, hard to diagnose, and mostly asymptomatic and in chronic cases do not reveal specific radiological and clinical signs for differential diagnosis. Therefore, in the evaluation of the soft-tissue lesions in patients with a history of a prior operation, it is wise to consider foreign bodies in the differential diagnosis.
