Rationale:
Intraorbital osteomas are incidentally found and occasionally require surgical treatment. Depending on their localisation, a single technique may not provide a sufficient surgical field.
Patient Concerns:
We report a 16-year-old male with a left upper medial palpable mass.
Diagnosis:
Computed tomography revealed a dense bony mass extending from the ethmoid sinus to the superior wall of the frontal sinus, with protrusion into the orbital cavity.
Treatment:
The combination of upper fornix transconjunctival and endoscopic transnasal approaches was chosen for the surgical removal procedure.
Outcomes:
The two-pathway approaches resulted in the clear removal of the mass. Post-operative recovery was rapid, although a slight restriction of the inferomedial duction remained at three months.
Take-Away Lessons:
This combination of techniques can provide a wide surgical field for the resection of frontoethmoidal osteomas with orbital extension.
