BACKGROUND: A 41-year-old male patient developed a sialocele after partial parotidectomy for a parotid pleomorphic adenoma. The sialocele was effectively treated by a single injection with botulinum toxin type B combined with multiple needle aspirations. METHODS: Ultrasound-guided infiltration of 2500 mouse-units of botulinum toxin type B in the residual parotid gland tissue under local anesthesia. Repeated needle aspirations were performed before and after the infiltration. RESULTS: Ten days after the injection, the patient was free of any discomfort. CONCLUSION: Botulinum toxin type B is effective in the management of postoperative sialocele after parotid gland surgery.
