“…Magnetic resonance imaging scan is also a useful diagnostic tool for NPDCs, where it provides exceptional definition of anatomy in the premaxillary region. 9 However, some of the drawbacks of these techniques are superimposition, poor visualization, and distortion of other anatomic structures. Nowadays, the introduction of CBCT provides the most accurate modality for preoperative evaluation of the maxillofacial region.…”

Nasopalatine duct cysts (NPDCs) are the most common nonodontogenic cyst of the jaw, with a reported prevalence of between 1% and 11.6% of all jaw cysts.1 It is believed to arise from epithelial remnants of the nasopalatine duct, the communication between the nasal cavity and anterior maxilla in the developing fetus. For huge NPDCs, total excision is difficult, and there is an increase in the possibility of postoperative complications including submucosal hematoma, wound dehiscence, wound infection, injury to tooth roots, injury to nasopalatine neurovascular bundles, paresthesia of the anterior palate, facial swelling, and oronasal fistula formation. This article discusses a case with a large NPDC, which was managed surgically without any complication. Radiological findings emphasizing the importance of cone-beam computed tomography in diagnosis and optimized treatment planning of NPDCs are discussed.

Abstract:Introduction. Nasopalatine duct cysts (NPDCs) are the most common developmental epithelial non-odontogenic cysts of the upper maxilla. Their etiological origin is still uncertain; NPDCs are often asymptomatic and are usually found randomly through local radio-diagnostic investigations carried out for other reasons. Main body. The aim of this investigation is to analyze and discuss the etiology, differential diagnosis, clinic-pathological characteristics of these lesions as well as to report the relative frequency and distribution of nasopalatine duct cysts in general population (NPDCs) with a literature's review on the topic. The retrospective study was carried out using 52 clinical cases, with histopatological confirmation for NPDC, radiographs and oral photographs. Data included age and gender of the patient, radiographic findings, etiological factors, treatment, and prognosis of NPDC. Few surgical consideration are discussed. The study results report a NPDCs' incidence of 2.39% and a male predilection with a 2:1.25 ratio. No statistically significant correlation was observed between the size of the lesion and patient's gender. Lesions were usually asymptomatic (73%). All cysts were located in the anterior maxillary midline region. Panoramic X-rays and computed tomography was used to identify the lesion. Surgical treatment was performed under local anesthesia including the dissection and the removal of the cyst, usually adopting a palatine approach with an enveloping flap from 1.4 to 2.4. Relapse occured in 15.4% of the cases. Conclusions. The etiology of NPDC is unclear and a male predilection was observed. The histological analysis of cystic lesions was fundamental for the final diagnosis. Simple surgical resection was recommended, followed by clinical and radiological control to ensure the correct and complete resolution of the case.

“…Sometimes, they can be treated solely by root canal therapy (non-surgical or surgical); Anyhow, the causative teeth need to be treated for healing to occur. Although some authors have advocated the use of computed tomography (CT), cone beam CT for dental use, and magnetic resonance imaging to differentiate between these lesions, 5 12 13 14 there is still an important role for panoramic radiography because of its low radiation exposure 15 low cost, and convenience.…”

Purpose The aims of this study were to create a deep learning model to distinguish between nasopalatine duct cysts (NDCs), radicular cysts, and no-lesions (normal) in the midline region of the anterior maxilla on panoramic radiographs and to compare its performance with that of dental residents. Materials and Methods One hundred patients with a confirmed diagnosis of NDC (53 men, 47 women; average age, 44.6±16.5 years), 100 with radicular cysts (49 men, 51 women; average age, 47.5±16.4 years), and 100 with normal groups (56 men, 44 women; average age, 34.4±14.6 years) were enrolled in this study. Cases were randomly assigned to the training datasets (80%) and the test dataset (20%). Then, 20% of the training data were randomly assigned as validation data. A learning model was created using a customized DetectNet built in Digits version 5.0 (NVIDIA, Santa Clara, USA). The performance of the deep learning system was assessed and compared with that of two dental residents. Results The performance of the deep learning system was superior to that of the dental residents except for the recall of radicular cysts. The areas under the curve (AUCs) for NDCs and radicular cysts in the deep learning system were significantly higher than those of the dental residents. The results for the dental residents revealed a significant difference in AUC between NDCs and normal groups. Conclusion This study showed superior performance in detecting NDCs and radicular cysts and in distinguishing between these lesions and normal groups.
