Maxillary sinus inflammatory disease: ultrasound compared to computed tomography
1Department of CT and MRI, Larissa General Hospital, Greece.
Summary
Ultrasound (US) is a reliable imaging tool for diagnosing acute maxillary sinusitis, showing high specificity. This study suggests US as a preferred first-choice method, especially for pediatric and pregnant patients.
Area of Science:
- Radiology
- Medical Imaging
- Otolaryngology
Background:
- Acute maxillary sinusitis is a common condition requiring accurate diagnosis.
- Computed tomography (CT) is a standard imaging modality, but ultrasound (US) offers potential advantages.
Purpose of the Study:
- To evaluate the diagnostic performance of ultrasound (US) compared to computed tomography (CT) for acute maxillary sinusitis.
- To determine the sensitivity and specificity of US in identifying maxillary sinus disease.
Main Methods:
- Prospective study of 56 patients with suspected acute maxillary sinusitis.
- Comparison of imaging findings between ultrasound (US) and computed tomography (CT).
- Ultrasound diagnosis based on identifying the hyperechoic posterior antral wall through hypoechoic inflammation.
Main Results:
- Ultrasound (US) demonstrated a sensitivity of 66.7% and a specificity of 94.9% for maxillary sinus disease.
- These results were comparable to plain film radiography.
- The key US finding was the hyperechoic posterior antral wall indicative of inflammation.
Conclusions:
- Ultrasound (US) is a highly specific and effective imaging method for diagnosing acute maxillary sinusitis.
- US is recommended as the primary imaging modality for acute maxillary sinusitis, particularly in children and pregnant women.
- US provides a valuable alternative to CT and plain films for evaluating maxillary sinusitis.
