Outpatient endoscopic removal of gutta-percha from the maxillary sinus using a sublabial antroscopy: a rare entity.

Any foreign body in the paranasal sinuses can cause chronic complications. It is therefore important to remove these foreign bodies meticulously. Various approaches are available to accomplish this. This article is a case report of a patient who had gutta-percha as a foreign body in left maxillary sinus, after a gutta-percha point had been used to trace a sinus to confirm that it was an oroantral fistula. Traditional surgical approaches to the maxillary sinus require invasive techniques, such as radical antrostomy and the Caldwell-Luc approach. These may result in further complications and morbidity. The gutta-percha point in this case report was removed endoscopically in an otolaryngology clinic with local anaesthesia using a sublabial antroscopy. There is only one case reported in the dental literature regarding the endoscopically-assisted technique for removal of displaced gutta-percha using the sublabial antroscopy approach (Yura S, Ohga N, Ooi K, Izumiyama Y. Procedure of endoscopic removal of a gutta-percha point in maxillary sinus mucosa by ultrathin arthroscope. Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2004;104:e58-60).
