Excerpt

Majority of the head and neck cancers arise in oral cavity and about 90% of them are squamous cell carcinomas [1].

The primary treatment modality adopted for GBS cancers is surgery and the close anatomical relation to the mandible warrants the need to appropriately address it, for superior oncological outcomes. The extent of resection of mandible, i.e., marginal versus segmental mandibulectomy, is dependent on the extent of involvement and the possible routes of entry of tumor into it, which is often at the junction of the reflected and attached mucosa [3]. …
