Small<unk> s that cause no discomfort often require merely clinical observation, with ultrasound being used to monitor the resolution of the hematoma. Large<unk> s, or those that are not becoming smaller or that are causing discomfort, usually require drainage. Also hematomas that occur after surgery for excision of a malignant tumor are drained, because a hematoma to which irradiation is applied is unlikely to ever resolve. A recent hematoma can be drained by means of needle aspiration or (rarely) open surgical drainage.
