Surgery-related salivary fistula is the result of intraoperative or postoperative parotid gland damage and extravasation of fluid secreted by acinar into the interstitial space. Most are treated conservatively. Local injection of botulinum toxin is an effective method, but it is relatively expensive and not available in some hospitals. In clinical practice, the authors observed that packing iodoform gauze from the fistula toward the parotid gland can quickly stop postoperative salivary fistula in several patients. This method is simple and easy to implement, and the effect is quick. The disappearance of the salivary fistula was observed on the next day after packing the iodoform gauze. Iodoform gauze packing is an alternative therapy for postoperative parotid fistula. It can be used in areas where botulinum toxin is not available.
