The collection also extends inferiorly deep to the hyoid bone into the paraglottic space causing mass effect on the epiglottis and effacement of piriform sinus.
The patient was managed with intravenous antibiotics and surgical drainage of left mandibular abscess. Wound swabs cultured mixed anaerobes and coagulase negative staphylococci.
