AIM: To investigate the effects of conjunctival approach, lateral approach, skin approach and lateral medial conjunctival approach on visual acuity, tumor residual rate and complications in patients with deep cavernous hemangioma of the orbit.

METHODS: Totally 114 patients with deep cavernous hemangioma of the orbit were divided into group A(30 cases, conjunctival approach), group B(34 cases, translateral approach)and group C(27 cases, transcutaneous)according to the surgical approach. The approach and the D group(23 cases, combined with the medial conjunctival approach via the lateral side), compared the visual acuity improvement effect, tumor residual rate and postoperative complications in the four groups.

RESULTS: There was no difference in visual acuity improvement between the four groups(P=0.918). The residual tumor rates of patients in group A, group B, group C and group D were 0, 2.9%, 3.7%, and 0, respectively. There was no difference in the incidence of postoperative complications between the four groups(P=0.244).

CONCLUSION: According to the indications of deep cavernous hemangioma of the orbit, the reasonable choice of minimally invasive surgery can effectively maintain the normal visual acuity level and the safety is consistent.
