A surgical procedure in which an incision is made into an antrum, typically the maxillary sinus, for therapeutic or diagnostic purposes.
From Latin 'antrum' (cave) + Greek 'tome' (cutting, incision). A surgical procedure name created in the 19th century following the '-tomy' suffix pattern for surgical procedures.
When doctors need to surgically access your sinuses, antrotomy is the procedure—literally 'cutting into the cave'—and it's been a key ENT technique since the 1800s.
