Management of traumatic parotid sialoceles and fistulae: a prospective study.

A prospective study of 13 patients with traumatic parotid fistulae or sialoceles showed that 54% resolved on conservative management within a 3 week period. Those that did not were treated by internal surgical drainage with uniform success, although care had to be taken with the catheter placement. No factors predictive of those cases requiring operative drainage other than failure of conservative management were found.
