Surgical treatment of orbital cavernomas

Surg Neurol. 2003 Sep;60(3):234-44; discussion 244. doi: 10.1016/s0090-3019(03)00136-8.


Background: There are numerous descriptions for the operative techniques applied in orbital lesions. We present a systematic overview of the surgical approaches, as determined by the location and extension of orbital cavernomas.

Methods: In our study, 37 patients (12 m, 25 f, aged 21-74 years, mean 51.22 years) underwent surgical removal of their orbital cavernoma at our clinic between 1988 and 2002.

Results: In ten cases the cavernoma was located in the lateral part of the intraconal space and a lateral orbitotomy was performed. Nine cavernomas were located more inferiorly and a transconjunctival approach was used. Seven cavernomas involving the optic canal, orbital apex and superior orbital fissure were operated on via an ipsilateral intradural approach. Four cavernomas of the superior orbital fissure or of the laterobasal intraconal space were approached extradurally. In one patient, a combined extra- intradural pterional operation was performed. Four patients with a lesion located medially in the posterior intraconal space were operated on via a contralateral pterional approach. One superior, medial, intraconal cavernoma was approached supraorbitally. In one cavernoma with direct contact to the sinus a transantral approach was used. The postoperative visual acuity improved in 14 of 19 cases with visual impairment, but in none with primary visual loss. Proptosis resolved completely in 21 of 27 patients. Ocular motility recovered in four of six patients, two patients with involvement of the superior orbital fissure presented with new oculomotor palsy postoperatively.

Conclusions: The location of the cavernoma determines the recommended surgical approach. Because of their tendency to lead to irreversible loss of visual acuity due to the mass effect, we favor early surgery after the onset of symptoms.
