Application of double Z-plasty and muscular pedicle island flaps to the lower lip defect due to dog bite avulsion: Report of a case

Abstract

The number of injuries caused by pets has been increasing recently. Although there are various types of wounds, most can be roughly classified into bite and scratch wounds.
There are a lot of reports on bite wounds on the face, especially on the lip, eyelid, nose, and ear. These wounds must be reconstructed from the functional and aesthetic points of view.
We treated a case of dog bite avulsion on the lower lip involving the mucocutaneous junction, skin and muscle by applying double Z-plasty and a muscular pedicle island flap.
The result was satisfactory.
