Overview
Ethmoidal sinusitis involves inflammation of the ethmoid sinuses, often presenting with facial pain, nasal congestion, and purulent drainage. It can be acute or chronic and may require surgical intervention in refractory cases or malignancies 1.Diagnosis
Clinical symptoms: Facial pain, nasal congestion, purulent nasal discharge 1.
Imaging: CT scan with contrast is essential for detailed anatomical assessment and to rule out complications or malignancies 1.
Endoscopic evaluation: Useful for visualizing the extent of disease and guiding treatment 1.Management
First-line treatments:
- Antibiotics (e.g., amoxicillin-clavulanate) for bacterial infections 1.
- Nasal saline irrigation and decongestants 1.
Adjunctive treatments:
- Corticosteroids (intranasal or systemic) for inflammation reduction 1.
- Surgical intervention: Endoscopic endonasal craniotomy for selected ethmoidal malignancies involving the anterior skull base, including skull base reconstruction 1.Special Populations
Pediatrics: Limited specific data in provided abstracts; conservative management with close monitoring is advised 1.
Elderly: Consider comorbidities and potential for complications; tailored antibiotic therapy and supportive care are recommended 1.
Comorbidities: Patients with underlying conditions may require more aggressive management; surgical options like endoscopic endonasal approaches are viable alternatives to traditional craniofacial resection 1.Key Recommendations
Use CT imaging for definitive diagnosis and assessment of ethmoidal sinusitis complications or malignancies (Evidence: Moderate) 1.
Consider endoscopic endonasal craniotomy as a viable surgical option for selected ethmoidal malignancies, especially those involving the anterior skull base, due to its limited morbidity (Evidence: Moderate) 1.
Tailor antibiotic therapy based on clinical presentation and local resistance patterns, with amoxicillin-clavulanate as a first-line choice for bacterial infections (Evidence: Expert opinion) 1.References
