Summary
This study reports a successful surgical removal of an orbitofrontal cholesterol granuloma using an anterior orbitotomy and endoscopic approach. The minimally invasive technique ensured no recurrence at two-year follow-up.
Area of Science:
- Neurosurgery
- Ophthalmology
- Otorhinolaryngology
Background:
- Cholesterol granulomas are rare, benign lesions that can occur in the orbit and frontal bone.
- Surgical management of orbitofrontal cholesterol granulomas typically involves open approaches like frontal craniotomy or lateral orbitotomy.
Observation:
- A 54-year-old male presented with an orbitofrontal cholesterol granuloma involving the left frontal bone and dura.
- The lesion was surgically excised using an anterior orbitotomy through a superior lid crease incision.
- A 70-degree rigid endoscope facilitated visualization and removal of the granuloma from the inner frontal bone and dura.
Findings:
- The combined anterior orbital and endoscopic approach resulted in successful resection of the cholesterol granuloma.
- The patient experienced an uncomplicated recovery with no signs of recurrence at the two-year follow-up.
- Histopathological confirmation of cholesterol granuloma was obtained.
Implications:
- This case demonstrates the efficacy of a combined anterior orbital and endoscopic approach for selected orbitofrontal cholesterol granulomas.
- This minimally invasive technique may offer an alternative to traditional open surgical methods, potentially reducing morbidity.
- Further research is warranted to evaluate the long-term outcomes and applicability of this approach in a larger patient cohort.
