  • Abstract
  • Look Inside

 A case of a 7 year-old boy complaining of a persistent infra-auricular fistula with a swelling of the right parotid gland of 5 months' duration is reported. The patient sustained a minor facial injury 3 years ago in which the retroauricular area was cut with a broken piece of the window glass. The wound healing was uneventful and the scar almost disappeared ; the parents had almost forgotten about this accident.

 After 3 years of dormancy, swelling of the parotid gland appeared with persistent purulent discharge from the fistula. Sialography revealed signs of localized chronic parotitis but without any signs of intraductal foreign body or abcess formation communicating with the ductal system.

 Exploratory operation revealed a piece of window glass measuring 25 x 15mm embedded within the deep lobe of the parotid gland encapsulated by dense fibrous tissues. Microscopically, the parotid glands showed a marked infiltration of inflammatory cells and interstitial fibrosis with atrophy of the acini.

 Glass pieces are the most frequently encountered foreign bodies in facial traumas, occasionally causing hypertrophic scar and localized tenderness ; they may be casually found in the secondary revision of the wound without any signs or symptoms.
