Abstract

Sialocele is a subcutaneous cavity containing saliva, caused by trauma or infection in the parotid gland parenchyma, laceration of the parotid duct or ductal stenosis with subsequent dilatation. It is characterized by an asymptomatic soft and mobile swelling on the parotid region. Imaging studies are useful and help establishing the diagnosis, such as sialography, ultrasonography, computed tomography and magnetic resonance imaging. This paper describes a recurrent case of a parotid sialocele in a young female patient. She presented a 6 cm x 5 cm swelling on the left parotid region. The ultrasonographic scan of the area revealed a hypoechoic ovoid well defined image suggesting a cyst. A sialography of the left parotid showed a cavitary sialectasia in a panoramic and anteroposterior view. A conservative management was adopted by percutaneous needle aspiration of the swelling, which was useful to provide material for analysis and helped healing. Dentists should be aware of this pathology and the importance in adopting a conservative treatment whenever it is possible.

Summary

Introduction

Sialocele is a subcutaneous cavity containing saliva, usually results from trauma or infection to the parotid gland parenchyma, laceration of the parotid duct or ductal stenosis with subsequent dilatation. Congenital fistulae and the ones secondary to invasive malignant tumors of the parotid gland or the oral cavity can be associated to sialocele. Temporomandibular joint surgery, parotidectomy, mastoidectomy, mandibular osteotomies and facial abscess drainage have been mentioned as potential causes of sialocele, and in all these cases the duct and/or the gland are damaged. Many treatment modalities have been mentioned in the literature They basically consist of a conservative or a surgical approach. Administration of botulinum toxin causes temporary chemical denervation of the cholinergic nerve fibers and has been used successfully. It is a highly effective, safe and non invasive method. The ultrasonographic scan revealed a hypoechoic ovoid well defined image suggesting a cyst (Figure 2)
