Management of Suspected Parotid Abscess
Diagnostic Approach
- The American College of Radiology recommends using high-frequency ultrasound (≥12 MHz) with Doppler as the first-line imaging examination to distinguish intraparotid from extraparotid masses, identify suspicious malignancy characteristics, and differentiate solid from cystic lesions 1
- The European Society of Radiology suggests that ultrasound with Doppler can help differentiate an abscess (peripheral Doppler signals) from a hematoma (absence of vascularity) 1
Therapeutic Management
- The Infectious Diseases Society of America recommends initiating broad-spectrum intravenous antibiotic therapy covering Staphylococcus spp. and Streptococcus spp., which are the most frequent pathogens, although the specific choice may depend on culture results 1
- The World Journal of Emergency Surgery suggests that the timing of surgery should be based on the presence and severity of sepsis, and that surgical drainage facilitates recovery and should be performed promptly once the diagnosis is confirmed 4
Special Considerations for Differential Diagnosis
- The World Journal of Emergency Surgery recommends using multiple counter-drainage incisions for large abscesses, rather than a single long incision that could create a stair-step deformity 3
- The American College of Surgeons advises against relying solely on imaging to determine the benign or malignant nature of a lesion, and recommends histological confirmation by fine-needle biopsy if malignancy is suspected 1
