[Planning and design of European prospective randomized trial on the value of drain in parotidectomy].

Introduction: There are no valid clinical studies on the value of wound drains in parotid surgery. The aim of the current trial is to analyze the influence of the closed wound drain (redon) on the incidence of postoperative complications such as bleeding, wound healing problems, infection, as well as salivary cyst and fistula after superficial or partial parotidectomy.

Methods: A European-wide multicenter prospective randomized study was planned.
