Primary squamous cell carcinoma of the frontal sinus treated with en bloc resection: case report

Abstract

A 66-year-old man presented with an extremely rare primary frontal sinus squamous cell carcinoma who was successfully treated by the extreme radical extended frontobasal approach. The tumor was resected en bloc with a clear margin and the large defect of the frontal region was reconstructed using a rectus abdominis myocutaneous flap. The tumor was well controlled without adjuvant therapy, and no recurrence or metastasis had occurred 2 years after the operation. Frontal sinus malignancy can be resected by the extreme radical extended frontobasal approach. The rectus abdominis myocutaneous flap is useful for the large defect of the skin and frontal base.
