Endoscopically assisted operative retrieval of parotid stones.

The treatment of large parotid stones remains a problem. We describe a technique in which microendoscopy is used to locate the stone and facilitate its removal. Over a 12-month period, eight patients were treated and seven stones removed successfully. The remaining duct was obstructed by a stricture. In six instances, the parotid duct was repaired and in two ligated. The mean follow up was 10 months (range 6-18) and there have been no complications. Our initial experience suggests that microendoscopy to locate the stone and facilitate its removal is an option in the management of persistent parotid stones.
