Superior orbital rim grinding as a novel surgical technique to approach superior and posterior orbital tumors.

Purpose: To describe a novel surgical technique aimed to approach those orbital lesions located superior and posterior to the equator of the globe.

Methods: We describe a novel surgical technique that was performed in four patients to approach intraorbital tumors superiorly and posteriorly located. This technique was completed through an upper eyelid skin crease followed by grinding the superior orbital rim to achieve complete removal of the lesions.

Evaluation and Management of Chemotherapy-Induced Epiphora, Punctal and Canalicular Stenosis, and Nasolacrimal Duct Obstruction.

Purpose: To describe the frequency, mechanisms, and treatment of epiphora caused by chemotherapeutic agents.

Methods: Review of relevant articles published in PubMed.

Results: The chemotherapeutic drugs best documented to cause epiphora are 5-fluorouracil and docetaxel; with both of these drugs, the main mechanism underlying epiphora is canalicular stenosis.
