Conservative or surgical management of orbital schwannomas: a population-based case series.

New Information and Importance:
This study provides insights into the management of orbital schwannomas (OS) in Sweden, comparing surgical and conservative approaches. It suggests that conservative management can be effective for patients with mild symptoms and low risk of neuro-ophthalmic impairment, with a proposed decision tree for managing OS.
Contribution to Literature:
The study adds to the limited literature on non-surgical management of OS, showing no significant difference in long-term outcomes between early surgery and delayed surgery following initial conservative management.
Results Summary:
– Study Period: 2005-2021, 16 patients with OS.
– Surgical Management: 4 patients underwent surgery; 3 achieved gross total resection (GTR, 75%), and 1 had subtotal resection (STR, 25%).
– Conservative Management: 12 patients; 3 eventually required surgery (25%).
– Follow-up: No tumor growth or recurrences in surgical patients (mean radiological follow-up 50 months, clinical follow-up 65 months). Conservatively managed patients remained clinically stable (mean follow-up 30 months), with one showing slight radiological progression after 17 months.
– Outcomes: No differences in long-term outcomes between early surgery and delayed surgery after conservative management.
Conclusion:
Conservative management is a viable option for certain OS patients, with surgery reserved for those showing clinical deterioration or tumor growth. The study’s findings support the development of a decision tree for OS management.
