Abstract

Correlation between the method of mandibular resection and local recurrence was studied in 41 patients with squamous cell carcinoma of the lower gingiva who underwent surgery from 1980 to 1991. The results were as follow:
1. Marginal mandibulectomy was performed in 18 patients, segmental mandibulectomy in 17, and hemimandibulectomy in 6.
2. Local recurrence occurred in 6 out of 41 patients. The rate of recurrence was 4/25 (16.0%) in T1·T2 patients and 2/16 (12.5%) in T3·T4, while it was 3/18 (16.7%) in patients who underwent marginal mandibulectomy and 3/23 (13.0%) in those who underwent segmental or hemimandibulectomy.
3. Marginal mandibulectomy was shown to be a very useful method of mandibular resection, but it was shown that wide resection of the soft tissue surrounding the mandible was important.
