A rare anatomical variation of the submandibular gland with three separate ducts opening into the oral cavity was observed. This finding is crucial for surgeons and radiologists during sialography to avoid missing potential pathologies.

Area of Science:

  • Anatomy
  • Surgical Anatomy
  • Radiology

Background:

  • The submandibular gland is a major salivary gland with a typically single excretory duct.
  • Variations in salivary gland ductal anatomy are uncommon but clinically significant.

Observation:

  • A unique morphological variation of the submandibular gland was identified, characterized by the presence of three distinct excretory ducts.
  • These three ducts independently terminated within the oral cavity.

Findings:

  • The uppermost and largest duct occupied the typical anatomical position relative to the lingual nerve.
  • The other two ducts presented an unusual anatomical arrangement.

Implications:

  • This anatomical peculiarity necessitates careful consideration during surgical procedures involving the submandibular region.

  • Radiologists performing sialography must be aware of this variation to ensure complete ductal opacification and accurate diagnosis of potential pathologies.
