Summary
Point-of-care ultrasound (POCUS) effectively diagnoses odontogenic infections, potentially reducing the need for computed tomography (CT) scans. This imaging technique aids emergency physicians in managing dental infections and abscesses.
Area of Science:
- Emergency Medicine
- Radiology
- Dentistry
Background:
- Odontogenic infections frequently present in emergency departments.
- While many cases are managed outpatient, complex abscesses require specialist intervention.
- Computed tomography (CT) is standard for complex odontogenic infections, but point-of-care ultrasound (POCUS) is emerging for soft tissue abscess diagnosis.
Purpose of the Study:
- To demonstrate the utility of POCUS in diagnosing odontogenic infections.
- To illustrate relevant sonographic anatomy for identifying these infections.
- To assess POCUS's potential to reduce CT utilization in emergency settings.
Main Methods:
- A case series of 10 patients with odontogenic infections diagnosed using POCUS.
- Detailed description of sonographic findings and relevant anatomy.
- Comparison of POCUS findings with clinical management and outcomes.
Main Results:
- POCUS successfully diagnosed odontogenic infections in all 10 cases.
- In some instances, POCUS guided treatment, obviating the need for CT scans.
- The study highlights specific sonographic features indicative of odontogenic pathology.
Conclusions:
- POCUS is a valuable tool for diagnosing odontogenic infections in the emergency department.
- Implementing POCUS can decrease reliance on CT scans for uncomplicated cases.
- Emergency physicians can effectively utilize POCUS for initial assessment and management of odontogenic infections.
