Management of the parotid pleomorphic adenoma, the problem of exposing tumour tissue at operation. The logical pursuit of treatment policies.

The objective of treatment of a parotid pleomorphic adenoma is to remove all tumour cells with minimal short- and long-term morbidity and minimal recurrence rates. If an enucleation is carried out, the facial nerve may be put at risk and tumour fragments will inevitably be left in the wound. Most surgeons suggest that after enucleation, radiotherapy must be given to reduce the recurrence rate to an acceptable level. If during a formal superficial parotidectomy the tumour capsule is visualised, the objective of removing the tumour with an intact cuff of normal tissue has failed and the operation has in effect become an enucleation. This paper defines the problem and discusses its management.
