A "round block" purse-string suture in facial reconstruction after operations for skin cancer surgery.

Removal of skin cancers in the head and neck region usually results in a circular or oval defect, which must be reconstructed immediately using one of several techniques. Larger defects can present a difficult aesthetic problem. The purse-string suture is particularly suited to such large defects where the skin is lax. We report 51 cases where this technique was used in the head and neck region. All defects were considerably reduced in size and some required a small skin graft to complete the reconstruction. Initially many redundant skin folds and considerable local distortion were seen but these improved with time. The technique is simple, inexpensive, and the results are satisfactory in appropriately selected cases. Comprehensive discussion to prepare patients for the gross initial distortion and the long period of retention of the suture makes the procedure acceptable to patients.
