Role of Cone-Beam Computed Tomography in Diagnosis and Management of Nasopalatine Duct Cyst

Abstract

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.

Peculiarities of organometric parameters of the hard palate in the second and third trimester of the intrauterine development and newborns

“…In the result of organometric measurements of the palatine maxillary process (hard palate) and horizontal lamina of the palatine bone during fetal and early neonatal periods of human ontogenesis it can be suggested that these structures are characterized by the periods of accelerated and relatively slow development. Certain data concerning organometric parameters of the hard palate are presented in the works by Guzik N. M. [11], Sane V. D. et al [14], Tessler A. Y. et al [19]. The length of the palatine maxillary process during the perinatal period was found to be characterized by the two periods of accelerated development (5-7 and 8-10 months), and the period of relatively slow development (7-8 months).…”

Nasopalatine duct cyst: A jigsaw puzzle

“…For the accurate diagnostic assessment, treatment planning and follow-up of patients suspected of having dental and maxillofacial disease, radiology is an essential aspect. 1 Until few years ago, periapical radiographs were the main radiographic investigation used in the endodontic treatment. 2 However, conventional radiography represents two-dimensional (2D) image of three dimensional (3D) objects with significant structure superimposition and unpredictable magnification.…”

Current Information on the Development and Formation of the Structure of Small Bones of the Facial Division of the Skull

“…Тому виникнення складних зубощелепнолицевих деформацій слід розглядати як наслідок порушень процесів росту, характеру й швидкості аппозиційної та енходральної побудови верхньої й нижньої щелеп на вільній поверхні або в місцях шовного з'єднання [18]. Від 10% до 12% щелеп, які розвиваються, мають аномальний розвиток [19][20][21].…”
