Preauricular tumor following tympanoplasty [Pr?aurikul?re Raumforderung nach Tympanoplastik]

摘要

A 42-year-old man presented with a preauricular subcutaneous pulsating node which had appeared a few weeks after a middle ear operation. CT angiography revealed an aneurysm of the superficial temporal artery. The diagnosis was histologically confirmed after surgical resection of the finding. This is the first description of an aneurysm of the superficial temporal artery as a rare complication of a tympanoplasty. In the presented case, the aneurysm must have been caused either by the surgical trauma of the endaural tympanoplastic incision or the sharp retractors.
