Anatomy and morphology of the nasopalatine canal using cone-beam computed tomography
Arpita Rai Thakur,Krishna Burde,Kruthika Guttal,Venkatesh G. Naikmasur 대한영상치의학회 2013 Imaging Science in Dentistry Vol.43 No.4
Purpose: This study was performed to evaluate the general anatomy and morphology of the nasopalatine canal using cone-beam computed tomography (CBCT) and to determine the human anatomic variability of the nasopalatine canal in relation to age and gender. Materials and Methods: The study included 100 subjects aged between 20 and 86 years who were divided into the following 3 groups: 1) 20-34 years old; 2) 35-49 years old; 3) ›50 years old. The subjects were equally distributed between the genders. CBCT was performed using a standard exposure and patient positioning protocol. The data of the CBCT images were sliced in three dimensions. Image planes on the three axes (X, Y, and Z) were sequentially analyzed for the location, morphology and dimensions of the nasopalatine canal by two independent observers. The correlation of age and gender with all the variables was evaluated. Results: The present study did not reveal statistically significant differences in the number of openings at the nasal fossa; diameter of the nasal fossa openings; diameter of the incisive fossa; shape, curvature, and angulation of the canal as viewed in the sagittal sections; antero-posterior dimensions and length of the canal in the sagittal sections; or the level of division of the canal in the coronal plane by age. However, males and females showed significant differences in the length of the canal in the sagittal sections and level of the division of the canal in the coronal plane. Conclusion: The present study highlighted important variability observed in the anatomy and morphology of the nasopalatine canal.

Non-Hodgkin's lymphoma (NHL) constitutes a group of malignancies those arises from cellular components of lymphoid or extranodal tissues. The head and neck is the most common area for the presentation of these lymphoproliferative disorders. Primary involvement of salivary glands is uncommon. This report described a case of a 73-year-old female patient who presented with involvement of both nodal and extranodal sites, with predominant involvement of salivary glands. The tumor staging worked up along with imaging, histopathological, and immunohistochemical findings were discussed. Computed tomographic images showed the involvement of Waldeyer's ring, larynx, orbit, and spleen. This report described imaging and prognostic tumor markers in diagnosing, treatment planning, and prognosis.
