Orbital Paraffinoma as a Complication of Endoscopic Sinus Surgery

Paraffin is a mineral oil that consists of straightchain saturated hydrocarbons. It was first discovered in 1830 and has been used medically since the 1880s. The injection of paraffin into tissues may cause a paraffinoma, characterized as a granulomatous foreign body tissue reaction.1 The body reacts to the nondigested hydrocarbon chains classically found in paraffin, Vaseline, and mineral oil. We report a patient with central postseptal upper lid paraffinoma after nasal septoplasty and endoscopic sinus surgery.
