Nasolabial Flap Based on the Upper Lateral Lip Subunit for Large Involuted Infantile Hemangiomas of the Upper Lip.

BACKGROUND

Large involuted upper lip infantile hemangioma is a challenge for plastic surgeon because of high visibility of disfigurement. To achieve an optimal reconstruction with matched color and texture, nasolabial flap based on the upper lateral lip subunit is used for the upper lip reconstruction.

METHODS

Records of 8 patients who underwent upper lip reconstruction from 2014 to 2018 at Shanghai Ninth People's Hospital were reviewed. After flap design according to the contralateral upper lip subunit, nasolabial flap was dissected and rotated to the defect. The donor site was subsequently closed by extensive undermining cheek skin tissue. The incisions were hidden in the border of lateral upper lip subunit.

RESULTS

There were a few deformities observed, including scar hypertrophy (4/8), alar flaring (2/8), and lower lid bulking (1/8). Five patients received following trimming procedures because of residual scars or deformity. All the patients were satisfied with the postoperative results. No obvious complications were observed.

CONCLUSIONS

The nasolabial flap based on the upper lateral lip subunit is a safe, effective, and reliable technique for correction of severe upper lip defect caused by large involuted infantile hemangioma. Although subsequent trimming procedures are required in some complicated cases, satisfactory results can still be achieved.
