Summary
Endoscopic surgery successfully removed a sphenoid sinus tumor invading the orbital apex. This minimally invasive approach improved vision, demonstrating its potential for complex orbital apex tumor resection.
Area of Science:
- Neurosurgery
- Ophthalmology
- Otolaryngology
Background:
- Endoscopic techniques are advancing for orbital apex exploration, primarily for tumor biopsy.
- Complete resection of orbital apex tumors via endoscopy remains challenging with limited reported cases.
Observation:
- A 64-year-old woman presented with a tumor in the sphenoid sinus invading the orbital apex.
- The patient experienced significant visual impairment.
Findings:
- Neuronavigated endoscopy and intraoperative Doppler sonography enabled complete tumor removal.
- Post-operative visual acuity improved from 5/16 to 5/6.
- Histopathological diagnosis confirmed the lesion as a cystis spuria.
Implications:
- This case highlights the efficacy of neuronavigated endoscopy and Doppler sonography for total resection of complex orbital apex tumors.
- The findings suggest potential for minimally invasive endoscopic management of similar challenging lesions.
- Improved surgical outcomes, including visual recovery, are achievable with advanced endoscopic techniques.
