Remember that the sphenopalatine artery runs with the nasopalatine nerve from the sphenopalatine foramen to the incisive canal. The sphenopalatine artery branches into the posterior lateral nasal artery and the posterior septal branch (Plate 3.29; described in detail in Section 3.3.2.1). The descending palatine artery is a branch of the maxillary artery that runs through the greater palatine canal before bifurcating into the greater palatine artery and the lesser palatine artery.

The periphery of the hard palate surrounding the necks of the teeth is termed the gingiva and a zone similarly lacking submucosa runs anteroposteriorly in the midline as a narrow, low ridge; the palatine raphe. At the anterior extremity of the raphe behind the incisor teeth is a small prominence, the incisive papilla that covers the incisive fossa at the oral opening of the incisive canal. Radiating outwards from the palatine raphe in the anterior half of the hard palate are irregular transverse ridges or rugae. The pattern of rugae is unique for the individual and has been used in forensic science to identify a dead individual.

These are rare, non-odontogenic, soft-tissue lesions arising from the incisive canal during the development of the maxilla. They present lateral to the midline at the alar base and can cause asymmetrical alar flare. Excision is usually via a sub-labial approach, but the transnasal approach has been recently reported.29

The frequency of the AMF in literature ranges widely from 1.4 to more than 20% [10,12,15,18,19]. In addition to ethnic variations, the wide range of the frequency might result from differences in methodology and definition of AMF. In this study, CBCT was used to evaluate the AMF in a selected Chinese population due to its accuracy, non-invasive nature and convenience for a large-sample research. The AMF was defined as an additional buccal foramen with its bony canal bifurcating from the mandibular canal. It was also essential to distinguish AMFs from nutrient foramina showing no continuity with the mandibular canal [9,20]. The additional buccal foramina originating from the mandibular incisive canal were not qualified as AMFs [6,21].
Transnasal endoscopic marsupialization of nasopalatine duct cysts: A novel ‘Mickey Mouse’ sign and a septum-sparing surgical technique to reduce paresthesia risk

The nasopalatine nerve runs through the nasal septum and courses through the mucoperichondrial, sloping downwards into the incisive canals to supply the hard palate, including the area adjacent to the upper incisors [13]. Damage to this nerve can lead to paresthesia or pain in this area. However, there may still be sensations due to dual supply from the anterior palatine nerve [14].
