Nasopalatine Duct Cyst

Abstract

The nasopalatine cyst is the most common epithelial and nonodontogenic cyst of the maxilla. The cyst originates from epithelial remnants from the nasopalatine duct. The cells may be activated spontaneously during life or are eventually stimulated by the irritating action of various agents (infection, etc.). It is different from a radicular cyst. The definite diagnosis should be based on clinical, radiological, and histopathological findings. The treatment is enucleation of the cystic tissue, and only in rare cases a marsupialisation needs to be performed. A case of a nasopalatine duct cyst in a 35-year-old male is reviewed. The typical radiologic and histological findings are presented.

Nasopalatine Duct Cyst: A Case Report

“…This cyst is the most common nonodontogenic developmental-evolutionary cyst of oral cavity [3]. It is believed that this cyst is originated from the remains of nasopalatine duct epithelium [3,5]. This cyst includes 10% of the jaw cysts [4] and involves 1% of the total population [3,6].…”

“…The invasive nature of these cysts should not be ignored because they can cause wide destruction [8]. In the differential diagnosis of the lesion we can refer to radicular cyst [4,8,14], keratocyst odontogenic tumour (KOT) [8,12], and central giant cell granuloma (CGCG) [5,9,14]. In terms of histopathology the epithelium of cysts is very diverse [12] and includes a combination of stratified, squamous, non-keratinized epithelium, false stratified columnar epithelium, stratified columnar epithelium, and simple cubic epithelium [8,12].…”

“…This cyst mostly causes divergence of the roots of the central teeth from each other and sometimes root resorption happens [4]. The most common differential diagnosis is a large foramen incisive [4]; in total, other differential diagnosis includes radicular cyst [4,8,14], keratocyst odontogenic tumour (KOT) [8,12], central giant-cell granuloma (CGCG) [5,9,14].…”

Deviated Nasal Septum as a Rare Symptom of Nasopalatine Duct Cysts: Two Case Reports and Review of the Literature

“…One interesting sign of both of the cases was the deviation of nasal septum and to our knowledge only 2 cases have been reported in the literature. 6,7 This sign can be the cause of the difficulty of breathing.…”

“…To our knowledge, only 2 case reports of NPDC associated with nasal septum deviation have been reported in the literature. 6,7 CASE REPORTS CASE 1 A 17-year-old female patient was referred to our hospital complaining of an uncomfortable feeling in the anterior palatal region. The patient mentioned that breathing through the nose was getting more and more difficult during the last couple of months.…”
