What is a incisive canal cyst?

Nasopalatine duct cyst, also termed as incisive canal cyst, arises from embryogenic remnants of nasopalatine duct, the communication between the nasal cavity and anterior maxilla in the developing fetus. Most of these cysts develop in the midline of anterior maxilla near the incisive foramen [3].

What is palatal cyst?

Summary. Median palatine cysts are a rare, nonodontogenic lesion of the hard palate that do not involve the palatine papilla or incisive canal and that usually present as asymptomatic, fluctuant swellings. They may involve the floor the nasal cavity but are treated by simple enucleation, without recurrence.

How is Nasopalatine duct cyst diagnosed?

The majority cases of the nasopalatine duct cyst are asymptomatic and diagnosed as an incidental finding during routine dental examination between the fourth and sixth decades of life, however if the nasopalatine duct cyst became large, it can cause painless swelling in the midline of the anterior palate, and sometimes …

What is Nasoalveolar cyst?

Nasoalveolar cysts, which originate from epithelial remnants of nasolacrimal duct, are nonodontogenic soft tissue lesions of the upper jaw. These cysts are thought to be developmental and are presented with fullness in the upper lip and nose, swelling on the palate, and sometimes nasal obstruction.

How common are Nasopalatine cysts?

The nasopalatine cyst is the most common non-odontogenic cyst of the oral cavity, at an estimated occurrence rate of 73%.

Which cyst is characteristically pear shaped?

The globulomaxillary cyst is a cyst that appears between a maxillary lateral incisor and the adjacent canine. It exhibits as an “inverted pear-shaped radiolucency” on radiographs, or X-ray films. The globulomaxillary cyst often causes the roots of adjacent teeth to diverge.

Can oral cysts go away on their own?

In most cases, no, you will not need to have an oral cyst removed. They tend to go away on their own or remain in a harmless state. However, when an oral cyst becomes infected, this is known as an abscess.

How do you treat a Nasopalatine duct cyst?

Nasopalatine duct cysts are treated by enucleation via a palatine or buccal approach; transnasal endoscopic marsupialization can also be applied. Recurrence is uncommon, having been reported in 0-11% of patients.

Where is a nasolabial cyst located?

INTRODUCTION. Nasolabial cysts are uncommon lesions located close to the alar cartilage of the nose, extending into the lower nasal meatus, the upper gingivolabial sulcus and the floor of the nasal vestibule.

Are nasolabial cysts benign?

A nasolabial cyst is a benign, slow-growing, nonodontogenic, primarily unilateral, extraosseous soft tissue lesion located in the nasal alar region below the nasolabial fold. The pathogenesis of nasolabial cysts is uncertain; however, there are two main theories.

How are Nasopalatine cysts treated?

What kind of cyst 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.

How big are cysts on the maxillary incisors?

The cysts are apical to the roots of the maxillary incisors and rarely cause root resorption. Cysts are round, ovoid or heart shaped due to the superimposition of the nasal spine. Cysts range in size, with an average diameter of approximately 1.5 cm [1].

What is the signal intensity of a maxillofacial cyst?

Usually shows homogeneous high signal intensity on both on T1 and T2, although most cysts of maxillofacial regions demonstrate low to intermediate signal intensity on T1 weighted images 1. Enucleation is usually curative, and recurrence is rare. Histological confirmation is recommended.

Where is the nasopalatine duct cyst in the mouth?

Radiographically the nasopalatine duct cyst is a well-demarcated radiolucency in the midline of the palate, apical to the central incisor teeth. The lucency varies from round to oval or heart-shaped.
