Sialocele is an uncommon complication of parotidectomy. Most cases resolve after conservative therapy consisting of repeated aspiration and pressure dressing. The condition is, however, occasionally resistant to such therapy. We report on a 52-year-old Chinese man who had a 10-year history of right parotid swelling. Following fine-needle aspiration cytology, Warthin's tumour was diagnosed, but ...

BACKGROUND Sialocele is a collection of saliva that has leaked from a damaged salivary gland or duct and is surrounded by granulation tissue. Surgery is the recognized first-line treatment. Recurrence rate after surgery is 5-14%. Salivary gland tissue is very sensitive to radiation therapy (RT). HYPOTHESIS/OBJECTIVES Radiation therapy will be useful for the treatment of sialocele. The aims we...

BACKGROUND Does the extent of parotidectomy or other patient or tumor characteristics influence the rate of sialocele/salivary fistula formation? METHODS All patients who underwent parotidectomy at the University of Wisconsin from 1994 to 2013 were considered. Patients who developed a sialocele/salivary fistula were identified. Extent of dissection, age, sex, body mass index (BMI), volume of ...

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 anesthe...

BACKGROUND The purpose of this study was to identify the prevalence of sialoceles and the risk factors associated with their formation after parotidectomy. METHODS We performed a retrospective analysis of the data from consecutive patients who underwent partial superficial parotidectomy of parotid tumors. Demographic data, preoperative imaging results, operative variables, including tumor typ...

Injuries to the parotid duct and parenchyma resulting in swelling in the cheek region commonly present in maxillofacial practice. Sialocele is a discrete collection of saliva in a subcutaneous cavity that can be iatrogenic, idiopathic or the result of post-traumatic injuries to the duct or parenchyma, presenting as a salivary pseudocyst or retention cyst. We present an unusual case of parotid s...

Injuries in the parotid and masseter region can cause serious impairment secondary to damage of important anatomical structures. Sialocele is observed as facial swelling associated with parotid duct rupture due to trauma. The aim of this paper is to report a case of a giant traumatic sialocele in the parotid gland, secondary to a knife lesion in a 40-year-old woman. Conservative measures could ...
