Giant torus mandibularis causing submandibular duct obstruction and sialadenitis

Area of Science:

• Oral and Maxillofacial Surgery
• Otolaryngology
• Radiology

Background:

• Torus mandibularis is a common, benign osseous outgrowth on the mandible's lingual surface.
• Typically asymptomatic, it's often an incidental radiographic finding.
• This condition rarely presents with significant clinical complications.

Observation:

• A patient presented with progressive floor of mouth pain and bilateral submandibular gland enlargement.
• Computed tomography revealed a giant torus mandibularis causing bilateral submandibular duct obstruction and dilation.
• This represents a novel presentation of torus mandibularis complications.

Findings:

• The giant torus mandibularis led to bilateral submandibular duct obstruction.
• This obstruction resulted in secondary sialadenitis (inflammation of salivary glands).
• Surgical resection of the torus mandibularis successfully resolved the patient's symptoms.

Implications:

• This case highlights a previously undescribed complication of torus mandibularis.
• Clinicians should consider torus mandibularis as a potential cause of obstructive sialadenitis.
• Early diagnosis and surgical intervention can lead to favorable outcomes for this rare complication.
