title: Pneumomediastinum after external dacryocystorhinostomy.
abstract: A 73-year-old man had right chronic epiphora for many years. After uneventful external dacryocystorhinostomy, he developed dyspnea and neck swelling after forcefully blowing his nose. CT showed diffuse cervicofacial subcutaneous emphysema and pneumomediastinum. He was admitted to prevent further cardiovascular complications. Pneumomediastinum is a rare complication of routine dacryocystorhinostomy. Supportive treatment to prevent additional air trapping is mandatory.
