Delayed Management of Parotid Sialocele: Role for Two-week Intraoral Drainage.

Iatrogenic injury or trauma to the salivary gland duct is one of the most common causes of parotid sialoceles, which are usually superficial, soft, and filled with saliva. The enrolled 7 patients with parotid sialocele were divided into two groups: trauma group (4 cases) and iatrogenic group (3 cases). No evidence of recurrence or cranial nerve injuries were observed. With persisted parotid sialocele, intraoral drainage for two weeks as a safe and inexpensive method is recommended.
