Summary
Endoscopic modified Lothrop approach (EMLP) with stereotactic assistance offers a safe, minimally invasive option for removing large frontal osteomas. This technique, sometimes combined with orbital surgery, shows promising results with no recurrence in observed cases.
Area of Science:
- Neurosurgery
- Otolaryngology
- Endoscopic Skull Base Surgery
Background:
- Frontal osteomas are benign tumors that can cause significant symptoms.
- Surgical removal is often necessary but can be challenging due to location and size.
Observation:
- Three patients with extensive frontal sinus osteomas were treated.
- Two patients underwent a stereotactic-assisted endoscopic modified Lothrop approach (EMLP).
- One patient with orbital extension required EMLP combined with anterior orbitotomy.
Findings:
- Stereotactic localization ensured skull base preservation in all cases.
- Two patients had uncomplicated post-operative recoveries.
- One patient required debridement for post-operative edema; no tumor recurrence was noted at follow-up.
Implications:
- Stereotactic-assisted EMLP is a viable, less invasive alternative to traditional open surgery for large frontal osteomas.
- The approach can be adapted with orbital surgery for complex cases involving orbital extension.
- This technique offers potential for reduced morbidity and improved patient outcomes.
