Body
Objective: The nasopalatine duct cyst(NPDC; incisive canal cyst) forms in the nasopalatine
canal and account for about 10% of jaw cysts. Osteoma is a benign tumor, originating from the
periosteum and may occur within the paranasal sinuses. In this report, we showed a case of
incisive canal cyst and osteoma imaged by Cone-beam computarized tomography (CBCT).
Methods: A 38 year-old male patient was referred for periodontal and prosthetic treatment.
Panoramic radiograph of patient revealed extensive alveolar bone loss. After the initial periodontal
treatment, CBCT imaging was performed for implant site assessment. CBCT revealed a
well-circumscribed, circular, radiolucent lesion in the center of the anterior hard palate. On
intraoral examination there was no pain and swelling, and overlying mucosa appeared normal
in colour. An incidental finding of a well-defined, uniform radioopacity in the medial part of
the left orbital region was recognised. The radiopaque mass was occupying a few space in the
frontal sinus and diagnosed as osteoma.
Results: The cyst in the midline of anterior hard palate was excisioned and histopathological
evaluation revealed NPDC. The patient was consulted to an ophtalmologist and an otolaringologist
for the osteoma. The osteoma did not interferes with normal function and not presents
a cosmetic problem so we kept the patient under observation for 6-month intervals.
Conclusion: This case is a good example of the kind of occult pathology found in CBCT datas
for oral and maxilofacial radiologists. CBCT scans must evauate for pathologies in order that
diagnose such occult pathologies.
