Tumors affecting the orbit include benign and malignant neoplasms arising from the various structures in the orbit including the blood vessels, nerves, bones, orbital fat and other soft tissues. The first step in the management of orbital tumors is to differentiate the malignant tumors from the benign ones. Complete surgical excision remains the primary treatment of choice for well-defined, clinically benign orbital tumors. On the other hand, for a suspected malignant tumor, an incision biopsy is the first step in the management to obtain a histopathologic diagnosis before a definitive therapy can be planned. Each orbitotomy technique is designed to provide the best surgical exposure to the lesion of interest, while causing least damage to the orbital structures, with a goal to achieve optimal functional and cosmetic outcome. The concept of minimally invasive surgery inherently includes hidden incisions and minimal dissection. There are variety of surgical approaches to the orbit. Having a thorough knowledge on the orbital anatomy and detailing out the size and extent of the lesion using pre-operative imaging can help the surgeon decide on the right approach.
