Cancer of the Retromolar Trigone (RMT)

Rodrigo Arrangoiz MS, MD, FACS, FSSO

  • The retromolar trigone (RMT) is a small triangular shaped subsite of the oral cavity:

    • It is the portion of mucosa that lies behind the third inferior molar tooth covering the anterior ramus of the mandible.

    • The base of the triangle is posterior to the last inferior molar tooth.

    • The apex is in continuity with the tuberosity of the maxilla behind the last upper molar tooth.

    • It is bounded laterally by the gingival buccal sulcus and medially by the anterior tonsillar pillar.

  • Cancerous lesions involving the RMT are almost always squamous cell carcinomas (SCC):

    • Minor salivary gland tumors are sometimes diagnosed in this subset.

  • Because of its continuity with the oral cavity mucosa and its close relation to the mandible, spreading to adjacent structures can easily occur.

  • Because squamous cell carcinoma of the retromolar trigone results in bone infiltration, lymph node metastasis and infiltration to the infratemporal fossa in the early stages, its prognosis is poorer than that of squamous cell carcinoma in neighboring areas, such as the tonsils, oral floor and gums.
