Summary
This summary is machine-generated.

Spheno-orbital meningiomas (SOMs) surgery can improve proptosis and vision, with bony decompression aiding outcomes. Safe maximal resection is preferred over aggressive gross total resection (GTR) to minimize morbidity.

Area of Science:

  • Neurosurgery
  • Ophthalmology
  • Oncology

Background:

  • Spheno-orbital meningiomas (SOMs) are rare tumors causing orbital proptosis and visual impairment.
  • Surgical management of SOMs presents significant challenges due to their location and potential for morbidity.

Purpose of the Study:

  • To evaluate surgical outcomes for vision and exophthalmos in patients with SOMs.
  • To identify predictors of outcome following surgical treatment of SOMs.

Main Methods:

  • Retrospective analysis of 17 surgically treated SOM patients.
  • Assessment of proptosis using exophthalmos index (EI) and orbital volume.
  • Evaluation of vision using Snellen's chart and Goldman's perimeter.

Main Results:

  • Proptosis improved in 64.3% and vision in 28.6% of patients post-surgery.
  • Gross total resection (GTR) was achieved in only 11.8% of cases.
  • Optic canal (OC) deroofing and orbital decompression improved proptosis and vision.

Conclusions:

  • Safe maximal resection, not aggressive GTR, leads to favorable outcomes for SOMs.
  • Bony decompression of orbital walls and OC is crucial for improving proptosis and vision.
  • While residual disease is common, adjuvant radiotherapy can lower recurrence risk.
