[Problems posed by loss of cheek tissue on a tumorous terrain]

The authors describe the case of a patient with right retrocommissural lesion treated by iridiumtherapy and an enormous orostoma which appeared three years later. Radiography showing a metallic opacity caused hesitation for some time between diagnosis of radionecrosis and a recurrence. Treatment called for extensive excision of the cheek. Satisfactory cover was obtained by means of a broad lingual flap for the deeper layers and by a cervical flap for the superficial layers.
