ABSTRACT
Abstract: Salivary duct injury can be idiopathic, iatrogenic, or post-trauma and may result in sialocele or fistula. Most injuries regress spontaneously and botulinum toxin A is one of several therapeutic possibilities. We report a case of iatrogenic injury to the parotid duct after Mohs' micographic surgery for a squamous cell carcinoma excision in the left jaw region, treated by injection of botulinum toxin type A. Although the fistula by duct injury can be self-limiting, botulinum toxin injection by promoting the inactivity of the salivary gland allows rapid healing of the fistula.

Parotid fistulae are a very infrequent complication after ear reconstruction in microtia when the local conditions are favorable. We report 2 cases of salival fistulae after microtic ear reconstruction. Timing of the diagnosis is important to decide the treatment. We recommend conservative management by restricted citric diet in early postoperative salival fistulae and Botox injections in the case that it persists.
