[Huge tumor resection defects on the parotid region repaired by lateral thoracic flap: a case report].

Lateral thoracic flap is a free flap for the reconstruction of soft tissue defects and has been previously used in oral and maxillofacial surgeries. We reported a case involving a huge soft tissue defect on the parotid region caused by the resection of parotid epithelial myoepithelial carcinoma. We discussed the anatomy and application of the lateral thoracic flap.
