Orbitofrontal cholesterol granuloma: percutaneous endoscopic-assisted curettage

Area of Science:

• Neurosurgery
• Ophthalmology
• Endoscopic Surgery

Background:

• Orbital cholesterol granulomas (OCG) are rare benign tumors.
• Traditional surgical approaches include lateral orbitotomy or frontal craniotomy.
• These methods can be associated with significant morbidity.

Observation:

• Two male patients with OCG underwent endoscopic curettage.
• A superior eyelid crease incision and a 70-degree rigid endoscope were utilized.
• The endoscope allowed visualization of curettage from the inner surface of the frontal bone and dura.

Findings:

• Both patients experienced uncomplicated recoveries.
• No recurrence of OCG was observed at eight months and two years post-surgery.
• Endoscopic curettage provided clear visualization and precise removal of the granuloma.

Implications:

• Percutaneous endoscopic curettage is a viable alternative to traditional OCG surgeries.
• This technique may reduce surgical trauma and improve patient outcomes.
• Further studies are warranted to establish endoscopic curettage as a standard treatment for OCG.
