ABSTRACT
BACKGROUND:
Cavernous venous malformations (CVMs) represent the most common benign intraorbital lesions. Enlarging or symptomatic CVMs (progressive proptosis or visual disturbances) are treated by surgical resection. For this, a variety of different surgical approaches have been described. The aim of this study was to present a contemporary series of orbital CVMs treated via open microsurgical approaches.METHODS:
In this study, patients who underwent resection of orbital CVMs between 2002 and 2019 were included. Presenting symptoms were noted and neuro-ophthalmologic examinations performed pre- and postoperatively. For surgical resection, the location of the orbital CVM and its relation to the orbital anatomy led to decision-making for appropriate approaches. A comparison between anatomical location and surgical outcome was performed.RESULTS:
Overall, 35 patients with orbital CVMs were included. Most common presenting symptoms were progressive proptosis (43%) and visual disturbances (34%). Most common location was the lateral quadrant (37%) followed by the superior quadrant (20%). A subfrontal craniotomy was performed in 40% of cases followed by a supraorbital craniotomy including the orbital rim in 34% of cases. For surgical excision, a cryo-probe was used in 30 patients, and complete resection was feasible in all cases. Location of a CVM within the superior quadrant was associated with improved postoperative recovery of visual acuity. No differences for clinical outcomes were observed depending on the surgical approach.CONCLUSIONS:
Resection of orbital CVMs is indicated in patients with visual disturbances or progressive proptosis. In these, microsurgical approaches can be used with minimal morbidity for complete removal of these well-circumscribed lesions.Palavras-chave
