Reconstruction of sphincteric function after dysfunctional total lower lip reconstruction using free muscle graft technique

Abstract

Many techniques can be used in primary reconstruction of total lower lip defects and most of them are functional. If a total lower lip defect is reconstructed with a static, dysfunctional technique, then the patient is prone to some problems such as drooling and gingival show. In order to restore sphincteric function in a previously reconstructed lower lip, we used the free muscle graft technique, which has been firstly used by Thompson for the treatment of facial paralysis. We obtained a satisfactory result, such that symptoms of drooling and gingival show have disappeared, and a minimal purse-stringing movement has been restored. To our knowledge, this is the first time of a free muscle graft application in this type of an indication. According to our result, the use of free muscle graft technique can be a good alternative method in patients, who suffer from drooling and gingival show following dysfunctional total lower lip reconstruction.
