Twelve patients with microinvasive squamous cell carcinoma of the lower lip were studied in order to determine whether vermilionectomy was justifiable. The maximum tumor thickness (MTT) varied between 1.1 and 3.1 mm. In none of the patients was there local recurrence during a mean follow-up period of 4.4 years (range 4-8). In view of these results and of what has been reported in the literature, it seems warranted to conclude that vermilionectomy is an appropriate procedure in microinvasive carcinoma of the lower lip with a MTT of up to 3 mm.
