Tumour spread in a delto-pectoral pedicle flap used in reconstruction of the lower jaw: case report.

A number of well-established pedicled flaps, including for example the delto-pectoral and pectoralis major flaps, are used in reconstructive work following excision of head and neck tumours. The most commonly encountered tumours of the head and neck spread predominantly via the lymphatic system and during the time between the insetting of a flap and the division of its pedicle some micro-lymphatic continuity of flow must develop from the site of insertion down the flap to its pedicle. This may form a route for spread of tumour when the primary lesion has been inadequately excised. A case report is presented.
