Summary
A minimally invasive surgical technique successfully removed a large frontoethmoidal osteoma. This combined endoscopic and orbital approach, aided by stereotactic localization, offers a promising alternative for treating sinonasal tumors.
Area of Science:
- Neurosurgery
- Otolaryngology
- Ophthalmology
Background:
- Frontoethmoidal osteomas are benign bone tumors that can cause significant local invasion.
- Surgical management of extensive tumors involving the sinuses and orbit presents challenges.
- Traditional orbitocranial approaches can be invasive.
Observation:
- A 28-year-old female presented with an extensive osteoma of the frontoethmoidal sinuses invading the orbital roof.
- The tumor was surgically excised using a novel combined endoscopic sinus and orbital surgical approach.
- Stereotactic localization was utilized to enhance surgical precision.
Findings:
- The combined sino-orbital approach facilitated successful tumor removal.
- Postoperative complications included temporary ptosis, diplopia, and supraorbital nerve anesthesia.
- All symptoms resolved completely within a 3-month postoperative period.
Implications:
- Stereotactic-assisted sino-orbital surgery is a viable and potentially less invasive option for selected frontoethmoidal osteomas.
- This technique may offer an alternative to more extensive orbitocranial resections.
- Further research can explore the long-term outcomes and broader applicability of this approach.
