The success of a repair is assessed by two essential criteria: The functional character of the lip (restoration of continence allowing feeding) and the aesthetic quality of the repair. However, for many patients from countries whose medical infrastructure does not allow them to undertake complex reconstructions locally, medical transfers represent their only chance of treatment. The aim of this article is to share with you an extreme clinical case of labial reconstruction, the management of which was a real challenge, using two major flaps: the free ante-brachial flap and the DUFOURMENTEL-type bi-pediculated scalp flap.展开更多

It is a slow-growing cancer, and can be diagnosed and treated easily and effectively;however, early treatment is important because its mortality rate is 10%-30%. Reconstruction for a large lower lip defect is surgically challenging, especially reconstruction with local flaps. Here, we present a 52-year-old male with a large T3 SCC, which started 13 years before this treatment and involved nearly all of his lower lip, oral commissure and upper lip. It was reconstructed by local flaps with good aesthetic and functional results. The lip was reconstructed with a combination of a Karapandzic flap on one side and a contralateral Webster cheek advancement, using a functional neck dissection on the tumor side and supraomohyoid neck dissection contralaterally. Histopathology results of the neck were negative for metastasis. We were satisfied with the aesthetic and functional results of the neck.展开更多
