Microscopically controlled surgical treatment for squamous cell carcinoma of the lower lip.

MCS has stood the test of time and has demonstrated an unusually high five year rate of cure of 94.2 per cent in a series of 1,448 consecutive patients treated over a period of 40 years. In addition, because of the selectivity of MCS, a maximal amount of normal tissue is conserved which permits repair of defects with unusually good functional and cosmetic results.
