ABSTRACT
The floor of mouth (FOM) is a common site requiring reconstruction following tumor extirpation. Regarding frequency of lesions occurring in the oral cavity, the FOM is second only to the oral tongue. Squamous cell carcinomas comprise the majority (90-95%) of these lesions (1). Other neoplasms include minor salivary gland tumors, sarcomas, and lymphoid tumors. For further details on pathologies of the oral cavity, see chapters 4 and 5: Pathology and Pathophysiology of the Oral Cavity-Neoplastic Diseases and Benign Lesions and Tumors of the Oral Cavity, respectively.
