title: Chronic facial pain following injection of sodium tetradecyl sulphate into an intraparotid haemolymphangioma.
abstract: OBJECTIVE
  We report a rare case of chronic facial pain following sclerotherapy for intraparotid haemolymphangioma, thereby highlighting an important clinical consideration when advising this treatment option as an alternative to surgery in the head and neck.
  
  
  METHODS
  Case report, with a review of relevant literature.
  
  
  RESULTS
  Sclerotherapy of lymphangiomata is well reported in the literature. Unusually, our young patient with an intraparotid haemolymphangioma experienced severe, chronic pain following intralesional injection of sodium tetradecyl sulphate, which required management by a specialist pain service. We discuss the technique of sclerotherapy for such lesions, and also discuss the potential side effects of two agents commonly used in our centre: OK 432 and sodium tetradecyl sulphate.
  
  
  CONCLUSIONS
  Non-surgical treatments of lymphangiomata and venous vascular malformations are not without complication. Both patient and clinician should be aware of this, and of the other potential side effects of sclerotherapy, prior to its use in the head and neck.
