Rationale:
Mucocoeles of paranasal sinuses are expansile and destructive lesions which can present with a variety of symptoms. If not treated early, they may lead to various complications.
Patient Concerns:
This report presents a case of a 26-year-old male patient with complaints of swelling of the left eye and double vision for 18 months.
Diagnosis:
Diagnosis of frontoethmoidal mucocoele with an unusual presentation of lateral displacement of the eyeball and proptosis was made based on patient history, clinical examination, and computed tomography.
Treatment:
The case was managed conservatively with marsupialization of the mucocoele using the transnasal endoscopic approach.
Outcome:
Complete resolution of the Mucocoele and its associated symptoms was observed, and frontal sinus ostium was found to be patent and completely epithelialized in 12-month follow-up.
Take-Away Lessons:
The endoscopic approach toward the management of frontoethmoidal mucocoele is an effective alternative to conventional surgery with less patient morbidity and mortality.
Insights
Frontoethmoidal mucocoeles, expansile sinus lesions, can cause eye symptoms. Endoscopic marsupialization offers an effective, minimally invasive treatment, resolving symptoms and ensuring sinus patency.
Area of Science:
- Otolaryngology
- Endoscopic Sinus Surgery
Background:
- Paranasal sinus mucocoeles are destructive lesions requiring timely intervention to prevent complications.
- Early diagnosis and treatment are crucial for managing these expansile growths.
Observation:
- A 26-year-old male presented with left eye swelling and diplopia for 18 months.
- Computed tomography revealed a frontoethmoidal mucocoele with lateral eyeball displacement and proptosis.
Findings:
- Transnasal endoscopic marsupialization successfully managed the frontoethmoidal mucocoele.
- The patient experienced complete symptom resolution, with a patent and epithelialized frontal sinus ostium at 12-month follow-up.
Implications:
- Endoscopic management of frontoethmoidal mucocoeles is a viable alternative to traditional surgery.
- This approach reduces patient morbidity and mortality, offering a less invasive treatment option.
