Tripaddled anterolateral thigh flap for simultaneous reconstruction of bilateral buccal defects after buccal cancer ablation and severe oral submucous fibrosis release: A case report

摘要

For buccal squamous cell carcinoma (SCC) patients accompanied with severe oral submucous fibrosis (OSF), it is a challenge to simultaneously reconstruct bilateral buccal defects created from cancer resection and contralateral OSF release to improve postoperative mouth opening. Herein, we present a case of reconstruction of bilateral buccal defects in a 46-year-old patient who had left buccal SCC accompanied with severe OSF. Extensive ablation involved the left full-thickness cheek as well as part of mandible and a release of right OSF tissue were performed. A tripaddled anterolateral thigh (ALT) flap with three independent sets of perforators was harvested for reconstruction. The flap survived in its entirety. No donor or recipient site complication occurred. The preoperative inter-incisor distance (IID) was 1 mm, while the postoperative IID was 23 mm. This is the first report on the use of one tripaddled ALT flap for reconstruction of bilateral buccal defects created from cancer ablation and severe contralateral OSF release.
