Sialocele formation is a recognised complication of parotid surgery. Most cases resolve after conservative therapy consisting of pressure dressing, fasting, and repeated aspiration. However, some cases are resistent to such treatment and require further intervention. In this report, we present the method of botulinum toxin (BTX) injection into the parotid gland under ultrasonographic guidance along with atropine injection. A 63-year-old female underwent excision of a pleomorphic adenoma abutting an accessory parotid gland. Sialocele formation persisted after almost 3 weeks of conservative therapy. BTX A was given under ultrasonographic guidance and the sialocele disappeared after two doses of treatment. BTX injection under ultrasonographic guidance was thus a safe and effective method for treating persistent sialocele.
