Abstract：Objective To summarize and evaluate the medium- and long-term efficacy of Gamma knife radiosurgery for orbital cavernous hemangiomas (OCH). Methods Clinical data of 45 OCH patients who received Leksell gamma knife therapy were analyzed retrospectively, including 36 lesions located in the orbital apex and 9 in the middle and anterior parts of orbit. The prescription peripheral dose arranged from 10.0 to 20.0 Gy with the median dose of 12.0 Gy. Results There was no new symptom related to cranial nerve dysfunction after gamma knife therapy. Exophthalmos was improved in 23 patients, visual acuity in 22 and transient chemosis occurred in 4. All the patients were followed up for 18 to 120 months with a mean period of 28.2 ± 9.4 months. MRI and/or CT reexamination showed that the lesion volume shrank in 41 patients (91.1％) and remained unchange in 4 (8.9％). No recurrence and reoperation occurred in all patients. Conclusions Gamma knife therapy can control the tumor growth for long term and achieve excellent neurological function preservation with rare complication, thus can be used as one of the main treatments for OCH and worthy to be popularized.
