Bilat eral occurrence and full patency were prevailing features in- the evaluated case reports of patent NPDs. Keywords Patent nasopalatine duct · Nasopalatine canal · Vomeronasal organ · Case report Introduction Patency of the nasopalatine duct (NPD) in humans is a rarely described anomaly of the anterior maxilla. Niels Stensen (1638–1686), a Danish anatomist and physician, was the first to provide a thorough description of the NPD in 1683 [ 24 ]. The NPD is often mixed up with the nasopalatine (incisive) canal (NPC). The NPC is a prominent structure within the anterior maxilla and represents a passageway originating bilaterally from the anterior nasal floor, subsequently fusing to form a single canal terminating at the incisive foramen in the anterior palate. The NPC conveys the nasopalatine arter- ies and nerves from the lower and anterior portion of the nasal septum to the palatal mucosa posterior to the maxillary incisors. The NPC further contains veins and seromucous glands [ through the NPC as an additional connection from the oral During the fetal period, an epithelialized duct also runs 28 , 49 ]. cavity to the so-called vomeronasal organ (VNO) [ The VNO (also called Jacobson’s organ) is located bilater ally at the bottom of the anterior nasal septum.

As a consequence, the Abstract Purpose update and summary of clinical findings of cases with a The objective of this review is to present an patent nasopalatine duct (NPD) reported in the literature from 1881 to 2016. Methods Previous articles and reviews about patent NPDs were studied and copies of all original publications were obtained for data verification. Furthermore, a litera ture search was conducted. In addition, the study sample- was complemented with four cases recently seen in our institution. Results Ten out of 67 published cases were to be excluded for this analysis due to misinterpretation or misreporting in previous articles. Overall, 57 cases with NPD patency could be analyzed. Males outnumbered females in a ratio of 2:1. The mean age (when this information was available) was 34.1 bilaterally (60%), unilaterally (20%) or centrally (20%). ± 17.6 years (range 6–69 years). NPDs were located Complete or partial patency was reported in 73.9 and 26.1%, respectively. 74.1% of patients presented a variety of clinical signs and symptoms. The ability of the patient to produce a squeaky or whistling sound was the most frequent clinical finding (23.8%). Conclusions Caution must be exercised when read- ing review articles about NPD patency since wrong data have been copied in several subsequent publications. Since
