Intraoral sonographic features of tongue cancer after radical radiotherapy.

Purpose: The purpose was to illustrate the sonographic changes of tongue cancer after radical radiotherapy.

Materials And Methods: In 24 patients with tongue cancer treated by interstitial brachytherapy (BRT) (uneventful recovery n = 16 , recurrence n = 5, severe soft tissue complication n = 3), follow-up examination were performed and both the margin and the vascular pattern were retrospectively assessed. We basically performed US examination at least once every 3 months after BRT within 1 year during follow-up period.
