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.
