Sumario:We report a case, function preservation of the upper lip after tumor resection was possible using residual orbicularis oris muscle and attached levator labii superioris alaeque nasi. Patient was 67-year-old male with squamous cell carcinoma at the vermilion border. The tumor was resected with an 8-mm margin, leaving the oral mucosa as intact as possible. To reconstruct the red lip, we used the oral mucosa as a rotational transposition flap. The white lip was reconstructed with a cheek rotation flap. A levator labii superioris alaque nasi muscle flap, which was attached to the remaining orbicularis oris muscle, was used to increase marginal lip volume. The movement of the reconstructed lip was good. At 9 postoperative months, induration of the red lip was palpable, and we suspected that the blood supply to the levator labii superioris alaque nasi was borderline insufficient. Slight drooping of the reconstructed lip occurred. We dissected this was caused by dissection of mid facial muscles from orbicularis oris muscle to ease downward rotation of the cheek flap and obscure the original nasolabial fold. Although some drooping and induration of the lip occurred, the white and red lip were reconstructed in a single-stage procedure, which resulted in good movement and preserved the function of the orbicularis oris muscle.
