Reconstruction of Lateral Gingivobuccal Defects After Oral Cancer Resection: A Systematic Approach Based on a Novel Classification.

This article presents a comprehensive approach to reconstructing lateral gingivobuccal defects following oral cancer resection. The authors propose a novel six-tiered classification system based on anatomic depth and tissue layers involved: Classes 1 to 3 address partial-thickness defects (mucosa ± muscle), progressing from no bone involvement (class 1) to marginal/upper alveolar (class 2), and segmental bone resection (class 3). Classes 4 to 6 address full-thickness defects (including skin), similarly progressing through no bone, marginal/upper alveolar, and segmental bone resection. The classification aims to standardize documentation, facilitate multicenter research, and guide flap selection.
