Orbital venous lymphatic malformations: case series on minimally invasive treatment approach

Orbital venous lymphatic malformations or lymphangiomas are choristomas of the orbit. Common in the pediatric population, the lesion is notorious for spreading into various anatomical spaces due to its infiltrative nature. Additionally, the vascular nature poses challenges to complete removal. Hemorrhages are not uncommon in the lesion, which may result in permanently compromised ocular function. Medical management involves injecting sclerosant into the cystic areas of the lesion, resulting in shrinkage and collapse, followed by total excision, which is the most suitable treatment option. The authors present a series of cases in which lymphangiomas have been completely excised using this minimal manipulative approach.
