[Insufficiency of a frontalis loop].

Abstract

After 13.5 years in vivo a 2-0 Terylene frontalis loop was excised because of an insufficiency. Histology showed a persisting giant cell reaction while lymphocytes were almost totally absent. The fibrils of the suture seemed to be intact. However, they were separated by ingrowing connective tissue which, on theoretical grounds, should improve the function of the frontal muscle on the upper eyelid. Therefore, insufficiency of the loop was probably caused by the (subclinical) foreign body reaction or the long-lasting mechanical stress leading to tissue damage.
