[Benign Neoplasms of the Orbit].

Benign orbital neoplasms comprise a wide spectrum of different entities. The origin of the tumours can be epithelial or mesenchymal. Epithelial neoplasms of the orbit originate from the lacrimal gland. The most important tumour is the pleomorphic adenoma, which should not be biopsied but resected in toto. The most common intraconal neoplasm in adults is the cavernous hemangioma. Symptomatic cavernous hemangiomas should be treated. The treatment of choice for most symptomatic benign neoplasms of the orbit is surgical resection. Suitable surgical approaches are anterior transconjunctival and lateral orbitotomy. Cryoextraction is a minimally invasive technique that is particularly suitable for cavernous hemangiomas. Georg Thieme Verlag KG Stuttgart · New York.
