Chest radiograph appearances after head and neck flap reconstructive surgery.

The chest radiographs of 17 patients who had undergone pectoralis major myocutaneous flap (PMMF) reconstruction for head and neck cancers were reviewed. Surgical procedure correlated well with radiographic findings, which consisted of the following signs: abnormal axillary and supraclavicular folds, replacement of normal vertical neck fold by an oblique fold, soft tissue mass and loss of facial plane at base of the neck. Unilateral radiolucent hemithorax was present in 41% of cases. In females, loss of breast shadow simulating the post-mastectomy appearance was present.
