Study Notes
Incisive Canal Cyst
- May appear as rounded, ovoid, or heart-shaped radiolucent area with well-defined margins
- Radiolucency located in the midline between the roots of the upper incisors
- Difficult to distinguish from a normal incisive canal if the cyst is less than 6 cm in diameter
Histopathology
- Epithelium:
- Type dependent on location:
- Near oral cavity: Stratified squamous epithelium
- Near the nose: Respiratory epithelium
- Type dependent on location:
- Connective Tissue:
- Fibrous connective tissue
- Chronic inflammatory cell infiltration
- Thick-walled blood vessels (branches of sphenopalatine vessels)
- Nerve trunks (nasopalatine nerve; best seen with silver stain)
- Cholesterol clefts occasionally seen
Contents
- Viscous fluid
- May contain mucoid material or pus (if infected)
- CT Variations:
- Mucous cells
- Sphenopalatine vessels
- Nasopalatine nerve
