Nasopalatine duct cyst.

Area of Science:

• Oral and Maxillofacial Surgery
• Radiology
• Pathology

Background:

• Nasopalatine duct cysts (NPDC) are the most common non-odontogenic cysts of the jaw.
• Their prevalence and clinical presentation can vary significantly across different populations.
• Aggressive and symptomatic presentations warrant detailed investigation.

Observation:

• A study of 114 cases identified NPDC as aggressive and symptomatic in the South African Black population.
• 30 Black patients presented with cysts exceeding 30 mm in diameter.
• Two cases with large, symptomatic NPDC, one infected, were evaluated using computed tomography.

Findings:

• Computed tomography (CT) is highly effective in delineating the full extent of NPDC.
• CT accurately demonstrates associated bony destruction caused by the cysts.
• The relationship of NPDC to adjacent anatomical structures is clearly visualized with CT.

Implications:

• Understanding population-specific presentations of NPDC is crucial for diagnosis.
• CT imaging is invaluable for surgical planning and management of large or infected NPDC.
• Further research into the factors contributing to aggressive NPDC in specific demographics is needed.
