“…If not detected or treated early, this can lead to a fusion with the canal, and may even compromise adjacent anatomical structures, such as perforation of the buccal/palatal alveolar cortex, nasal cavity cortex and maxillary sinus floor. 3,12,13 Enlargement of NPC has been mostly reported to be idiopathic. However, recent evidence suggests an association between anterior maxillary dento-alveolar trauma and increased dimensions of the NPC.…”

“…However, recent evidence suggests an association between anterior maxillary dento-alveolar trauma and increased dimensions of the NPC. 3,14 Clinically, this pathological enlargement of NPC can lead to teeth displacement and destruction of surrounding bone as well as compromising dental implant placement in the esthetic zone. 14 The aim of this CBCT-based study was to assess NPC enlargement resulting from NPC-PRL fusion and its relationship with surrounding anatomical structures in patients with a known history of maxillary anterior dento-alveolar trauma compared to an age-and gender-matched control group.…”

“…They also found that osteolytic lesions with bucco-palatal dimensions of more than 5mm were more prone to fusion. 3 In relation to surgical procedures, such as implant placement or bone grafting in anterior maxilla, an early diagnosis and surgical enucleation of the lesion is required to prevent surgical site infection. The penetration of NPC during implant placement is not an unusual phenomena 31,32 and optimal treatment of such lesions beforehand is essential for a good prognosis.…”

“…1,2 It mainly contains the nasopalatine nerve and terminal branches of the nasopalatine artery surrounded by connective tissue and seromucous glands. 3,4 The application of conventional two-dimensional (2D) imaging techniques, such as intra-oral radiography, to assess the maxillary anterior periapical region provides limited information and can lead to inaccurate interpretation of a periapical radiolucency (PRL) related to the central incisors. [5][6][7][8] Factors influencing periapical assessment include morphologic variations, surrounding bone density, x-ray angulation and radiographic contrast.…”

Background/Aim There is lack of evidence regarding the radiological characteristics of a periapical radiolucency fusion with the nasopalatine canal following dento-alveolar trauma. The aim of this study was to assess the nasopalatine canal (NPC) enlargement resulting from fusion with a periapical radiolucency and its relationship with the surrounding anatomical structures. Material and methods A total of 100 patients were retrospectively recruited and divided into two groups: case group and control group. The case group consisted of 50 cone-beam computed tomography scans of the maxilla of patients (32 males, 18 females; age range: 11-83 years) with a known history of dento-alveolar trauma in the maxillary anterior region and presence of an undiagnosed and/or asymptomatic nasopalatine canal-periapical radiolucency fusion. An age-and gendermatched control group of 50 patients (32 males, 18 females; age range: 11-82 years) without trauma history to the upper anterior teeth, demonstrating normal maxillary scans was recruited. A subjective scoring criterion was established for assessing the characteristics of the fused lesion and its relationship with the buccal/palatal alveolar cortex, nasal cavity cortex, nasopalatine canal cortical border and maxillary sinus floor. Results The fused nasopalatine canal-periapical radiolucency was mainly lobular in appearance (88%) with non-corticated well-defined margins (80%). Male patients showed larger (68%) dimensions compared to female patients (32%). The nasopalatine canal cortical bone was the most commonly perforated structure in relation to fusion (72%), whereas, maxillary sinus cortical bone was the least effected (2%). A statistically significant difference was observed between the nasopalatine canal dimensions in the control and test groups, with fused lesions having larger mesio-lateral, cranio-caudal and bucco-palatal dimensions (p<0.001). Conclusions Periapical radiolucencies should be treated as soon as possible before they fuse with NPC. In case of fusion, surgical enucleation should be considered as the treatment of choice.

“…Etiologie vzniku cysty ductus nasopalatinus je stále nejasná. V současné době se předpokládá, že nejpravděpodobnější příčinou je lokalizovaný úraz nebo infekce v místě epiteliálních zbytků v oblasti nazopalatinálního kanálu [9]. Na základě imunohistochemického profilu epitelu cyst ductus nasopalatinus se zdá, že cysta může být odvozena od Malassezových epiteliálních ostrůvků a může mít spojitost se vznikem apikální periodontitidy [10].…”
