Transglabellar resection of frontal sinus cholesterol granuloma extending cranially through cecum foramina: Technical note.

BACKGROUND

Cholesterol granuloma (CG) commonly occurs in the petrous apex; their occurrence in the anterior cranial fossa CGs is rare. Subfrontal approaches are the conventional surgical approaches for the resection of midline lesions of the anterior cranial fossa and frontal sinuses. In this article, we describe a successful minimally invasive approach for resection of a small midline anterior cranial fossa CG.

METHODS

We report a rare case of frontal air sinus CG extending intradurally through the foramen caecum. The surgical management of this patient involved the use of a minimally invasive transglabellar approach and a butterfly incision and the patient outcomes at 1 year after the surgery.

RESULTS

The lesion was totally resected with no complications and the patient was discharged on the 3rd postoperative day. A 1-year follow-up scan showed neither residual nor recurrence of the lesion.

CONCLUSION

The transglabellar approach through a butterfly incision offers a safe approach for the resection of a lesion extending from the frontal air sinuses to the anterior cranial fossa with no complications, shorter hospital stay, and good cosmetic results.
