[Therapy of tumors of the anterior orbit]

Tumors of the orbit are diagnosed on clinical and neuroradiological criteria. A biopsy may histologically confirm uncertain mass lesions. The patients' age and medical history predispose for certain tumor entities among the rather heterogenous spectrum of possible diagnoses. The therapy depends on the degree of malignancy and its location within the orbit. Among the different options, surgical excision is the most common followed by radiation therapy either in combination with surgery or alone. Chemotherapy plays a subsidiary role in certain lymphomas or metastases. This review covers the surgical techniques and treatment principles for tumors of the anterior orbit, explains radiotherapy techniques and briefly covers chemotherapy. Pediatric tumors of the orbit are covered separately.
