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 (3rd)

  • 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 is common:

        • Its prognosis is poorer than that of squamous cell carcinoma in neighboring areas:

          • Such as the tonsils, oral floor and gums
