Objective:
To investigate the functional reconstruction technique for partial lower lip defects.
Methods:
7 patients with lower lip cancer (3 cases of basal cell carcinoma, 2 cases squamous cell carcinoma and 2 cases papillary carcinoma) underwent excision. The full-thickness lower lip defects were one-third to two-third of the total lower lip length. All the defects were reconstructed with V-Y island advancement flaps based on the mental neurovascular bundle.
Results:
There was no flap loss. No recurrence was observed during the follow-up period of 3 months to one year. Both the aesthetic appearance, muscle function and sensation of the reconstructed lower lip were satisfactory.
Conclusions:
Mental neurovascular V-Y island advancement flap is an ideal method for functional repair of partial lower lip defect.
