Head and neck abscess usually requires hospitalization, intravenous antibiotic therapy, and surgical incision and drainage. Open surgical drainage may result in unsightly scars. We report two cases of a 56-year-old man with a facial abscess and a 47-year-old man with a parotid abscess. The patients were successfully treated with ultrasound-guided angiocatheter irrigation and drainage without scar. Ultrasound-guided angiocatheter irrigation and drainage can be a simple, safe and effective alternative procedure to open surgery in the management of the selected head and neck abscesses.
