A Rare Cause of Chronic Rhinosinusitis Secondary to a Retained Pledget: A Case Report.

Chronic rhinosinusitis (CRS) is a widely prevalent disease. Retained objects as the cause of CRS are not commonly reported in the literature. The impact of the removal of this object is also a point of interest. The purpose of this case report was to investigate a patient whose CRS was suspected to be due to a foreign object and his postoperative course. A 37-year-old male patient presented to the clinic with a chief complaint of right-sided nasal congestion, severe maxillary sinus pressure, and green thick nasal drainage for many years. He reported a history of dental and endonasal surgery on that side 8 years ago in Saudi Arabia. Imaging showed complete opacification of the right maxillary sinus and anteroinferior nasal cavity and several irregular-shaped radio-opaque materials within this region. His symptoms were refractory to medical management, and he chose to undergo endoscopic sinonasal surgery. A piece of gauze was removed from the right sinonasal cavity and maxillary sinus. In the weeks following surgery, his symptoms and inflammation fully resolved. Retained objects or material within the nose and sinuses are not commonly reported in the literature. This patient's CRS was secondary to a preventable cause. His increased morbidity after his initial surgery 8 years ago could have been avoided with careful attention to surgical counts.
