ABSTRACT
A 31-year-old man is presented and is evaluated by panoramic radiography. As a finding, an extensive lesion with a cystic appearance was detected in the anterior part of the maxilla. Computed tomography shows a lesion corresponding to the characteristics of a cyst. In the histology the combination of two types of epithelium is observed, pseudostratified columnar and stratified squamous, confirming that this was a nasopalatine duct cyst.
Se presenta el caso de un hombre de 31 años, evaluado mediante radiografía panorámica. Como hallazgo se detecta una extensa lesión de aspecto quístico en la parte anterior del maxilar. En la tomografía computada se observa una lesión que corresponde a las carácterísticas de un quiste. La histología muestra una combinación de dos tipos de epitelio, pseudostratificado columnar y estratificado escamoso, confirmando que se trataba de un quiste del canal nasopalatino.

The nasopalatine duct cyst is the most common non-odontogenic developmental cysts, comprising 10% of jaw cysts and occurring in 1 of every 100 persons with a slight male predilection, the mean age being 42.5 years. This article reports an unusual case of nasopalatine duct cyst occurring in an 11year male pediatric patient associated with supernumerary teeth.
ABSTRACT
BACKGROUND: Nasopalatine duct cysts (NPDCs) are considered the most common non odontogenic cysts of the maxilla. Although the recommended treatment is complete removal of the lesion, complications, such as hematoma or fistula, can occur, especially in extensive cases. The aim of the present paper was to introduce transnasal endoscopic marsupialization as an efficient and useful treatment for NPDC. MATERIALS AND METHODS: A retrospective review of 5 patients with extensive NPDCs (>2 cm) protruding into their nasal cavities was performed. All patients underwent endoscopic endonasal marsupialization. In order to survey the long-term, subjective outcomes, telephone interviews were conducted. RESULTS: The mean age of the included patients with NPDC was 32 years and all were male. Most of the patients had facial pain (100%) and nasal obstruction (80%), and somepatients complained of palate swelling (60%). There were no perioperative complications. The mean OPD follow-up duration was 3.7 months and a telephone survey was conducted with 4 patients at a mean of 27.5 postoperative months. Patients complained of some crust formation in the nasal cavity, but no cyst relapse or other significant complications were reported. CONCLUSIONS: A large NPDC protruding into the nasal cavity can be easily and efficiently managed with endoscopic endonasal marsupialization as a substitute for complete enucleation.

Nasopalatine duct cyst is a common cystic lesion of nonodontogenic origin of the maxilla. Diagnosis was made on the basis of physical examination and radiological findings. Generally, the treatment of choice for nasopalatine duct cyst is the enucleation of the cystic tissue. Recently, we performed marsupialization via trans-nasal approach in two cases. Both patients exhibited no evidence of recurrence and showed good results. Thus, we report two cases of nasopalatine duct cysts with a literature review.

OBJECTIVE: To present a case and discuss the clinicopathological characteristics of nasopalatine duct cyst and discuss the etiology, diagnosis, treatment and prognosis, with a review of the literature. DISCUSSION: Nasopalatine duct cyst occurs in approximately 1% of the population. Presentation may be asymptomatic or include swelling, pain, and drainage from the hard palate. Surgical treatment was carried out under local anesthesia and comprised the dissection and removal of the cyst adopting a usually palatine approach.
OBJETIVO: Apresentar um caso e discutir as características clínico-patológicas do cisto de ducto nasopalatino, discutinfo a etiologia, diagnóstico, tratamento e prognóstico, revisando a literatura. DISCUSSÃO: Os cistos naso-palatinos ocorrem em aproximadamente 1% da população. A apresentação pode ser assintomática ou incluir edema, dor e drenagem purulenta do palato duro. O tratamento cirúrgico foi sob anestesia local e constituiu de dissecção e remoção do cisto, via acesso palatino.

Os cistos do ducto nasopalatino são entidades incomuns dos maxilares, mas que podem assemelhar-se clínica e radiograficamente a outras lesões císticas e sólidas da região anterior mediana da maxila. O objetivo deste trabalho foi reportar 4 casos de cisto do ducto nasopalatino buscando discutir suas características microscópicas e de diagnóstico diferencial relevantes na prática clínica odontológica. As informações demográficas, clínicas e imaginológicas foram obtidas a partir dos registros laboratoriais dos pacientes e as lâminas histológicas coradas em hematoxilina e eosina dos 4 casos foram revisadas sob microscopia ótica. Os 4 casos acometeram homens com média de 53 anos de idade e todas as lesões eram assintomáticas. As imagens radiográficas eram radiolúcidas uniloculares, localizadas entre os incisivos centrais superiores e com tamanho médio de 2,0 cm (variando de 1,0 a 4,0 cm). Todos os casos foram tratados através de enucleação cirúrgica e a análise microscópica revelou que 3 dos 4 casos eram revestidos por mais de um tipo de epitélio, sendo o epitélio pavimentoso estratificado não queratinizado o mais comum. Conclui-se que os cistos do ducto nasopalatino acometem usualmente homens adultos, assemelhando-se aos cistos periapicais associados aos incisivos centrais superiores e que devem ser tratados através de procedimentos cirúrgicos conservadores com posterior avaliação microscópica minuciosa do espécime removido.
Nasopalatine duct cysts are uncommon maxillary lesions that can clinically and radiographically resemble other cystic and solid lesions from the maxillary midline area. The aim of this study was to report 4 additional cases of nasopalatine duct cyst focusing on the daily clinical importance of their microscopic and differential diagnosis characteristics. Demographic, clinical and radiographic information was obtained from the patient´s laboratory registries and hematoxilin and eosin stained histological slides from all cases were reviewed under light microscopy. The 4 cases affected males with a mean age of 53 years and all lesions were asymptomatic. Radiographic images were radiolucent and unilocular, between the roots of the upper central incisors measuring a mean of 2,0 cm (ranging from 1,0 to 4,0 cm). All cases were managed through surgical enucleation and microscopic analysis revealed that 3 of the 4 cases were lined by more than one epithelium type, the most common being stratified squamous epithelium. In conclusion, nasopalatine duct cyst usually affect adult males, are similar to periapical cysts associated to upper central incisors, and should be managed by conservative surgical approach followed by careful microscopic evaluation of the surgical specimen.
ABSTRACT
Nasopalatine duct cysts (NPDC) are common cystic lesions of non- odontogenic origin of the maxilla. Patients with NPDC generally undergo surgical enucleation via transoral approach. However, with the recent introduction of sinonasal endoscopy and subsequent advances in surgical techniques, endoscopic management has become possible. This study reviews a case of a 40- year-old man had a one-month history of nasal obstruction and swelling of the hard palate. Nasal endoscopy revealed a cyst in the nasal floor and hard palate. He underwent successful endoscopic marsupialization of NPDC. This simple and less invasive surgical procedure should be considered in the future treatment of NPDC.

The nasopalatine duct cyst, known as the incisive canal cyst, is the most common nonodontogenic cyst in the maxillofacial area. It is believed to arise from epithelial remnants of the embryonic nasopalatine duct. Nasopalatine duct cysts are most often detected in patients between forties and sixties. The trauma, bacterial infection, or mucous retention has been suggested as etiological factors. The cysts often present as asymptomatic swelling of the palate but can present with painful swelling or drainage. Radiologic findings include a well demarcated cystic structure in a round, ovoid or heart shape presenting with a well-defined bone defect in the anterior midline of the palate between and posterior to the central incisors. Most of them are less than 2cm in size. On MRI, the cyst is identified as a high-intensity, well-marginated lesion, which indicates that it contains proteinaceous material. We experienced a case of a 61-year-old female patient who had a 2.3*2.6*1.7cm sized nasopalatine duct cyst. The bony defect after a surgical extirpation was restored with hydroxyapatite. So we report a good results with some reviews of the literatures.
