What is incisive canal cyst?
Incisive canal cysts, also known as nasopalatine duct cysts (NPDC), are developmental, non-neoplastic cysts arising from degeneration of nasopalatine ducts. These ducts usually regress in fetal life. The persistence of ductal epithelium leads to formation of cyst.
What does nasopalatine cyst mean?
The nasopalatine cyst is the most common epithelial and nonodontogenic cyst of the maxilla. The cyst originates from epithelial remnants from the nasopalatine duct. The cells may be activated spontaneously during life or are eventually stimulated by the irritating action of various agents (infection, etc.).
Is nasopalatine cyst odontogenic?
Nasopalatine duct cyst also known as nasopalatine cyst is a developmental, epithelial, non-neoplastic cyst that is considered to be the most common non-odontogenic cyst in the maxillofacial region. It is unique in that it develops in only a single location – the midline anterior maxilla.
What passes through incisive fossa?
It is immediately behind the incisor teeth. The incisive foramen is continuous with the incisive canal, located behind the central incisor teeth in the incisive fossa of the maxilla. It allows for blood vessels and nerves to pass….

What is the incisive papilla?
The incisive papilla otherwise known as palatine papilla is a small pear or oval shaped mucosal prominence situated at the midline of the palate, posterior to the palatal surface of the central incisors.
Do Nasopalatine cysts have to be removed?
In this case, nasopalatine duct cyst is very huge. The standard treatment for NPDC is complete removal through a sub-labial or palatine approach. Cystectomy and fenestration surgery of the nasal cavity may is an option for treatment of huge maxillary cysts, such as NPDC, in the midline.
Is foramen and fossa the same?
Foramen – A hole through which nerves and blood vessels pass. Examples include supraorbital foramen, infraorbital foramen, and mental foramen on the cranium. Fossa – A shallow depression in the bone surface.
What is the function of incisive canal?
The incisive canal is located in the anterior part of the hard palate and serves as a communication between the oral and nasal cavities. Soft tissue and neurovascular structures, namely, the nasopalatine nerve and sphenopalatine artery, traverse the length of this canal.
What passes through the incisive fossa?
The incisive foramen is continuous with the incisive canal, located behind the central incisor teeth in the incisive fossa of the maxilla. It allows for blood vessels and nerves to pass….

Where is the incisive papilla?
The incisive papilla is a small tubercle of the mucous membrane which is located lingual to 2 maxillary central incisors at the midline of the hard palate [Drake et al., 2005]. The papilla receives sensory innervation from the nasopalatine nerve through the incisive foramen.
What is an incisive canal cyst?
Incisive canal cyst. Dr Maxime St-Amant ◉ and Dr Gagandeep Singh et al. Incisive canal cysts, also known as nasopalatine duct cysts (NPDC), are developmental, non-neoplastic cysts arising from degeneration of nasopalatine ducts. These ducts usually regress in fetal life.
What is the size of the incisive fossa in squamous cell carcinoma?
Although extremely rare, malignant transformation (squamous cell carcinoma) has been reported The incisive foramen by convention is not expected to exceed 6 mm A radiolucency in this region with ill defined borders is regarded as a large incisive fossa
What causes a cyst on the incisive papilla?
In this instance, is termed cyst of incisive papilla, or cyst of palatine papilla Exact trigger that stimulates development is unknown, but factors proposed include trauma and infection Second: theory now out of favor; originates from trapping of epithelial remnants during embryologic fusion between nasal cavity and anterior maxilla
What is the typical size of a cyst wall?
Variable size, mean diameter ~1.5 cm Lined by stratified squamous epithelium alone or with pseudostratified columnar epithelium (variable cilia and goblet cells), simple columnar epithelium or simple cuboidal epithelium Cyst wall is composed of fibrous tissue with nerves, cartilaginous rests, arteries and veins
