title: [Complications from sinonasal surgery].
abstract: Endoscopic sinonasal surgery is the main procedure in sinonasal pathology. Complications are rare but potentially severe given the close relationship between the nasal cavities and sinuses and the orbit, skull base and carotid arteries. The different types of surgeries along with the mechanisms of injury, presenting signs and symptoms, and imaging features of the different surgical complications will be reviewed. We will also review the anatomical variants increasing the surgical risk that radiologists should describe on preoperative imaging studies.
