Foreign bodies in the maxillary sinus are not unusual findings. Many cases have been reported so far with foreign bodies like tooth, dental amalgam, chopstick, matchstick, gutta-percha point, pellets, and even bullet. This paper reports a unique presentation of a patient with regurgitation of fluids in nose and an oro antral fistula; which was later found out to be ribbon gauze as foreign body in the maxillary antrum and was retrieved by Caldwell-luc approach. Introduction Foreign bodies in the maxillary antrum are not a rare entity, with most of them being iatrogenic in nature and most commonly follow dental procedures. Foreign body in the maxillary antrum may present as an acute phenomenon or may remain silent for years. Some patients present with swelling in the cheek, nasal discharge, nasal regurgitation due to oro-antral fistula etc., to name a few. Computerized tomographic scan aids in diagnosis and should be done in all suspected cases apart from routine radiographic investigations. Some of them masquerade as a neoplastic lesion even. Retrieval of the foreign body is done by either caldwel-luc method or minimally invasive endoscopic assisted surgery, both having their own merits and demerits. Case Report A 65 year old male patient came to the out-patient department of ENT with chief complaints of regurgitation of fluids into the nose and a hole in the palate at the site of previous tooth extraction, for 7 months duration. He had no change in voice and had no cough, no dysphagia. He had no other significant medical or surgical history. Detailed cranial nerve examination was insignificant.On examination the patient had draining oro-antral fistula in the left upper molar region (fig.1).
