Incisive Canal Cyst in an Intellectually Disabled Patient with First and Second Branchial Arch Syndrome : A Case Report

Evaluation of the snowing-like ultrasonographic features of intraosseous jaw pathologies.

Aim of the study: Ultrasonographic examination of intraosseous jaw pathologies may reveal interesting incidental, mobile hyperechoic particles (“snowflakes”) in anechoic areas. Purpose of this study is to explain and discuss this snowing-like ultrasonographic feature of intraosseous jaw pathologies. Material and methods: This study included 113 patients admitted to our clinic for examination: 43 (38.05%) males and 70 (61.9%) females with a mean age of 34.9 ± 17.2 years (range: 6–72 years). A total of 120 intraosseous lesions were evaluated prior to surgery using ultrasonography; these included non-neoplastic, odontogenic, and non-odontogenic lesions. Results: In total, 5 (4.1%) of the 120 lesions exhibited snowing-like feature on ultrasonography, including 2 (1.6% of total) of 3 incisive canal cysts, 2 (1.6% of total) of 7 dentigerous cysts, and 1 (0.8% of total) of 19 odontogenic keratocysts. Conclusions: Snowflakes evident on ultrasonography of intraosseous jaw lesions may be specific to certain pathologies. Future studies correlating radiologic and pathologic features of intraosseous jaw lesions should focus on ultrasonographic snowing-like appearance in different types of lesions and explore why they occur.

Accuracy for diagnosis of periapical cystic lesions

Clinical differentiation between cystic lesions of endodontic and non-endodontic origin is of importance because correct diagnosis may affect treatment decision making. Most radicular cysts are treated with conservative approaches and, therefore, are not surgically removed. The objective of this study was to determine the accuracy of clinical diagnosis of periapical lesions as compared to the histological findings, and to evaluate various associated factors. All biopsy specimens submitted for histological evaluation from 2002 to 2009 were assessed. Only cases of periapical lesions with complete patient data and clinical diagnosis were included. Sensitivity, specificity and accuracy of the clinical diagnosis were calculated and various patient-related factors were evaluated. Of the 4,908 cases, 183 met inclusion criteria. Histologically, there were 171 lesions of radicular cysts and 12 cases of non-endodontic cysts, including OKC and Incisive Canal Cyst. The diagnostic accuracy for clinical diagnosis for radicular cysts was 91.84% and 91.84% for non-endodontic cysts. There was a high accuracy of clinical differentiation between cystic lesions of endodontic and non-endodontic origin. However, some non-endodontic lesions may be incorrectly diagnosed clinically as lesions of endodontic origin. Histological evaluation may be necessary for the correct diagnosis. Further clinical studies are needed to evaluate clinical examination and histological diagnosis of periapical lesions.

Advocacy of diagnostic criteria for maxillary incisive canal cysts based on alteration of normal maxillary incisive canals according to aging in Japanese populations

BackgroundThe purpose of the present study was to describe the CT imaging findings of normal incisive canals and incisive canal cysts and propose cut-off values to differentiate between them.MethodsA total of 220 normal subjects and 40 patients with incisive canal cysts on multi-detector row computed tomography (MDCT) were retrospectively analyzed. The shapes, sizes, anatomic variations, Hounsfield scale values, and so on of maxillary incisive canals and the sizes and Hounsfield scale values of maxillary incisive canal cysts were analyzed.ResultsA significant difference in sizes of maxillary incisive canals in normal subjects was found between males and females. The sizes of maxillary incisive canals were significantly wider during aging, but shapes, anatomic variations, and Hounsfield scale values in the maxillary incisive canals were not significantly different with aging. A significant difference in sizes but not Hounsfield scale values was found between normal maxillary incisive canals and maxillary incisive canal cysts. Based on a cut-off of over 6 mm in the width of incisive canals, maxillary incisive canal cysts could not be appropriately diagnosed for subjects over 60 years of age. Over 60 years of age, maxillary incisive canal cysts could be appropriately diagnosed based on a cut-off of over 7.1 mm in width of incisive canals. When maxillary incisive canals of the hourglass types were seen on sagittal sections, significantly more patients had maxillary incisive canal cysts than other types.ConclusionIn coincidentally diagnosing asymptomatic incisive canal cysts on imaging, we should apply different cut-offs for the size of the maxillary incisive canal for patients over and under 60 years of age. Specifically, the cut-offs for the long axis of maxillary incisive canal cysts were 7.1 mm for patients over 60 years of age and 6.0 mm for those under 60 years of age. In addition, we should pay attention to wider canals with hourglass shapes as indicative of cystic change of maxillary incisive canals.

EVALUATION OF INCISIVE CANAL CYSTS: 2-D VS 3-D IMAGING. HAVE WE LEARNT ANYTHING NEW?

<h3>Background</h3> Incisive canal cysts, also known as <i>nasopalatine duct cysts</i> (NPDCs), are developmental, nonneoplastic cysts arising from degeneration of nasopalatine ducts. They are considered the most common nonodontogenic cysts. They are usually discovered incidentally; they can occur at any age but are most commonly reported to occur in 4th to 6th decades, have a male predominance, and affect approximately 1% of the population. <h3>Objective(s)</h3> The aim of this study was to compare the radiographic features of nasopalatine duct cysts on 2-D periapical radiographs and cone beam computed tomography (CBCT) scans to understand the value of addition of 3-D imaging in the diagnosis and treatment planning of these cysts. <h3>Study Design</h3> 17 cases of histopathologically confirmed incisive canal cysts were evaluated in this study. Periapical radiographs and CBCT scans of these patients were evaluated by an oral radiology resident and a board certified oral radiologist. <h3>Results</h3> In all cases, incisive canal cysts were seen as a solitary, well-defined, oval or round, unilocular radiolucency located between the central incisors. The size varied but was larger than 0.5 cm in diameter. The 2-D images did not always confirm the diagnosis; at least 12 cases were reported as possible cysts but needed 3-dimensional (3-D) imaging for confirmation. Analyzing the same cases on CBCT scans confirmed the diagnosis. CBCT examination showed that mesiodistal extent and importantly buccolingual expansion could be evaluated. Precise measurements could be calculated to plan for surgery. In 6 cases, root resorption or tooth displacement could be seen as an additional feature on 3-D imaging. The effects of these cysts on adjacent structures, including thinning and perforation of the buccal cortical plates, could be evaluated. <h3>Discussion/Conclusions</h3> The value of adding 3-D imaging compared with 2-D imaging alone was in confirming the radiographic diagnosis, evaluation of the extent of the cysts, especially the buccolingual dimensions, and the effects on adjacent structures.

NASOPALATINE DUCT CYST MIMICKING AS RESIDUAL CYST- AN ENIGMA IN CLINICAL DIAGNOSIS- A CASE REPORT

Incisive canal cyst or nasopalatine duct cysts (NPDCs) are the most common non-odontogenic cysts of the maxilla. These are the common intraosseous developmental cyst occurring in the midline of the maxillary anterior region. They are usually asymptomatic and are discovered incidentally during the routine radiographic examination. They can be described as a well-circumscribed radiolucency between the root apices of the maxillary central incisors. Since these lesions show diagnostic dilemma in clinical and radiological study, a definitive diagnosis is required to be confirmed by histopathology. Surgical approach with enucleation of the cyst is the definitive treatment of NPDC. Hereby, we report an unusual presentation of NPDCs mimicking as residual cyst which was associated with missing upper anterior teeth.

The Role of Cone-Beam Computed Tomography in Diagnostics of Cystic Masses of the Jaw

Research objective. The study aimed to evaluate cone-beam computed tomography (CBCT) capabilities in diagnostics of cystic masses of the jaw.Methods. Over a period of 2015–2016 32 patients age 6 to 67 underwent both panoramic tomography and CBCT (using panoramic tomographic scanner STRATO 2000 and cone-beam computed tomographic scanner i-Cat respectively). 47% (n = 15) of the participants were women, 53% (n = 17) – men. Radiation exposure for a single procedure amounts to 0,05 mSv for panoramic tomography, 0,07 mSv for CBCT (FOV =13 cm), 0,06 mSv for CBCT (FOV =8 cm).Results. Comparative analysis of obtained results demonstrates that CBCT showed 54% (n = 27) more cystic masses of the jaws than panoramic radiography could. CBCT additionally showed the following pathologies: granulomas smaller than4 mm diameter – 85% (n = 23), 83% (n = 23) of said granulomas were found on maxilla, radicular cysts of maxilla – 11% (n = 3), incisive canal cyst – 4% (n = 1). Additionally panoramic tomography analysis misdiagnosed 5 granulomas (80% (n = 4) on mandibular premolar and molar areas) that were not found during CBCT analysis.Conclusion. The low effective dose and high informativity of CBCT enables the method to be used instead of intraoral radiography, panoramic tomography and MSCT as a screening procedure in diagnostics of dento-facial system pathologies, including cystic masses of the jaw.

BÜYÜK BOYUTLU NAZOPALATİN KANAL KİSTİ: OLGU SUNUMU

Nasopalatine duct cysts (NPDC), also known as incisive canal cysts, is the most common developmental, epithelial, non-odontogeniccyst of the maxilla. NPDCs are located in the anterior maxillary midline region. The cyst arises from embryonic epithelial remnants of the nasopalatine duct within incisive canals. Lesions are normally asymptomatic and are usually detected during the routine radiological examination. Diagnosis is most frequently performed in the fourth and sixth decades. NPDCs must be especially distinguished from large incisive foramen and radicular cyst of central incisors. Recurrence is rare following surgical removal. In this case report, a 57 years old male patient’s NPDC is evaluated by panoramic radiography and cone beam volumetric tomography images which is existing in the maxillary midline; between right and left canine’s roots and its treatment presented

Nasopalatine duct cyst: A case report

Incisive canal cyst or nasopalatine duct cysts (NPDCs) are the most common nonodontogenic and developmental cysts of the maxilla. These developmental NPDC are usually asymptomatic and are discovered during routine radiological examination done for some other diagnosis. A cone-beam computed tomography (CBCT) is a valuable tool to localize a cyst within the nasopalatine canal. CBCT enables analysis of the dimension of the NPDC, analysis of the involvement of neighboring anatomical structures and assists in treatment planning. Histopathology shows non-keratinized epithelium with pseudo stratification, ciliation with neuro-vascular bundle in the capsular wall. Surgical approach with enucleation of the cyst is the mainstay in the treatment of NPDC. Since these lesions show diagnostic dilemma in clinical and radiological study, a definitive diagnosis is made by histopathology. Here we report a case of 27-year-old male patient with NPDC along with brief literature review.

CBCT imaging of extensive nasopalatine duct cyst :Case report

The nasopalatine duct cyst (incisive canal cyst) (NPDC) is the most common non-odontogenic cyst in the oral cacity, occuring approximately 1% of the population. It is an uncommon condition that generally occurs in the maxillofacial bones. This lesion may be clinically silent for years without any symptoms. On examination, painless swelling, which was tender and fluctuant, was confirmed in the midline of his anterior hard palate. The overlying mucosa appeared normal in color. We performed CBCT to better identify lesion.This case demonstrates the typical clinical and radiographical features of a NPDC. CBCT can provide high-resolution images, short scanning time, and reduced radiation dose. CBCT therefore provides the opportunity for multiplanar imaging and three-dimensional (3D) information.

Nasopalatine duct cyst

The nasopalatine duct cyst, also known as a nasopalatine cyst or incisive canal cyst, is a developmental, non-neoplastic cyst that is considered to be the most common nonodontogenic cyst. It is one of many pathological processes that may occur within the jawbones. This article reports the case of a

Nasopalatine duct cyst or periapical pathology: An enigma

Nasopalatine duct cyst NPDC also known as nasopalatine canal cyst or incisive canal cyst, is a developmental, non-neoplastic cyst arising from degeneration of nasopalatine ducts. These ducts usually regress in fetal life. The persistence of ductal epithelium leads to formation of cyst. Development of cyst is attributed or triggered by several factors like infection 38%, trauma 16%, minor salivary mucus retention, inflammatory stimulus, spontaneous proliferation of epithelial remnants present in the nasopalatine duct. Radiographically they are seen as a solitary well-defined, oval or round unilocular radiolucency, between central incisors, >0.6 cm in diameter. They may appear heart-shaped if the anterior nasal spine superimposed. In this article a case of NPDC with a history of trauma is described. Its diagnosis was based on clinical, radiographic, and histologic findings. The nasopalatine cyst requires no surgical treatment when it is small and asymptomatic. In rare cases it increases in size and may even destroy bone. In this case report we have described surgical management of the lesion with postoperative follow-up for 1 year.

Transnasal Endoscopic Marsupialization for a Huge Nasopalatine Duct Cyst With Nasal Involvement

Nasopalatine duct cysts (NPDCs), also known as incisive canal cysts, are the most common nonodontogenic cyst of the jaw, with a reported prevalence of between 1% and 11.6% of all jaw cysts. A developmental cyst, the NPDC is believed to arise from epithelial remnants of the nasopalatine duct, the communication between the nasal cavity and anterior maxilla in the developing fetus. Precipitating factors in the development of an NPDC have been reported to be trauma, infection, and spontaneous occurrence.

Nasopalatine Duct Cyst: Report of a Case with Review of Literature

The nasopalatine duct cyst is the most common non-odontogenic developmental cysts. Nasopalatine duct cyst also termed as incisive canal cyst, arises from embryologic remnants of nasopalatine duct. Most of these cysts develop in the midline of anterior maxilla near the incisive foramen. This article reports a case and review of literature with respect to epidemiology, etiology, clinical presentation, radiographic and pathological findings, treatment and recurrence rates.

上顎骨に発生した骨内黄色腫の1例

Xanthoma is a benign tumor consisting of accumulations of lipid-laden histiocytes associated with fibrous connective tissue. The large spherical tumor cells containing lipids are called foam cells. Xanthoma usually arises in the soft tissue including the skin, tendon sheath, and eyelid. However, xanthoma in the jaw bones is rare. We report a case of xanthoma occurring in the maxilla of a 66-year-old woman.The patient consulted a dental clinic because of spontaneous pain in the left side of the nose. Since an X-ray film demonstrated a cystic lesion in the left incisor region of the maxilla, the patient was referred to our hospital. Panoramic tomography and computed tomography also revealed a cystic lesion in the same area. The clinical diagnosis was an incisive canal cyst. Under general anesthesia, the lesion was extirpated. The removed lesion was a yellowish, elastic-soft mass adhering to the periosteum. Histologically, the lesion consisted of accumulations of foam cells without atypia, scattered foreign body giant cells, and fibrous connective tissue. The pathological diagnosis of the lesion was xanthoma. There was no evidence of recurrence 23 months after surgery.

Incisive Canal Cysts Related to Periodontal Osseous Defects: Case Reports

The incisive canal cyst is the most common non-odontogenic cyst of the oral cavity. While the cyst has frequently been described, the relationship between the lesion and adjacent periodontal osseous defects has rarely been reported. This paper describes the occurrence and treatment of incisive canal cysts in two patients with severe adult periodontitis on maxillary incisor teeth.

Intra-osseous squamous cell carcinoma of the maxilla: probably arisen from non-odontogenic epithelium

This paper reports a case of intra-osseous squamous cell carcinoma (IOSC) of the maxilla. The patient was a 52-year-old male with a chief complaint of swelling of his hard palate. The lesion was initially diagnosed as an incisive canal cyst from the clinical and radiographic findings, but histological examination revealed the lesion to be a poorly differentiated squamous cell carcinoma. The review of the literature yielded only a few previous cases of IOSC of the maxilla, which were probably of odontogenic origin. The present maxillary IOSC is thought to be non-odontogenic in origin.

A diagnostic case involving an incisive canal cyst

An incisive canal cyst was misdiagnosed as an endodontic lesion. The patient's chief complaint was pain on mastication with increasing intensity for the last 2 days. The single original periapical radiograph revealed a well-circumscribed radiolucency related to the apex of the maxillary right central incisor. The patient was referred with a request for endodontic therapy. A subsequent angled radiograph revealed an interroot location of the lesion, and pulp testing showed a normal response. The patient was then referred for surgical treatment. Following removal of the lesion, the histopathologic examination confirmed the diagnosis of an incisive canal cyst. One-year follow-up showed complete healing and maintained tooth vitality, and the patient was asymptomatic.
