Buccal squamous cell carcinoma is an aggressive form of oral carcinoma with a high
recurrence rate. Injury to the parotid duct is often unavoidable when surgically treating
buccal squamous cell carcinoma because of the intimate anatomic relation among the
buccal mucosa, Stensen duct, and parotid gland. It is often difficult to achieve negative
margins and preserve the integrity of the parotid duct. Sialocele formation is a frequent
and untoward complication owing to extravasation of saliva into the surgical defect,
which delays healing, creates fistulas, and produces painful facial swelling. Currently,
no consensus exists regarding the management of a parotid sialocele. Multiple investigators
have described different modalities of treatment, such as repeated percutaneous needle
aspiration, pressure dressings, antisialagogue therapy, radiotherapy, botulinum toxin,
and surgical techniques, including duct repair, diversion, ligation, drain placement,
and parotidectomy.
