Anatomical Parameters of Nasolacrimal Duct Evaluated by Computed Tomography in Healthy Children

The importance of anatomical topography in nasolacrimal duct stenosis.

In our previous study the inclination of nasolacrimal canal in relation to Frankfurt horizontal plane has been analysed on 71 anatomically preparated human skulls by introducing the probe through canal. The results of that study showed that the alpha angle in the frontalplane was greater than 91 degrees in 27% of cases, i.e., nasolacrimal canals descend diverging in relation to the median plane...

Human cerebral asymmetries evaluated by computed tomography.

The handedness of seventy-five persons without evidence of neurological disease, was assessed with a standardised test. An analysis of the CT scans of the same persons was performed to determine (1) presence and lateralisation of frontal and occipital "petalia," (2) width of frontal and occipital lobes of each hemisphere, (3) direction of straight sinus deviation. Results suggest that handednes...

Preoperative Computed Tomography Findings for Patients with Nasolacrimal Duct Obstruction or Stenosis

PURPOSE To identify and analyze the role of preoperative computed tomography (CT) in patients with tearing symptoms with nasolacrimal duct obstruction (NLDO). METHODS We retrospectively reviewed the medical records and CT results on 218 patients who complained of tearing symptoms with NLDO between January 2014 and December 2014. All patients were recruited from Kim's Eye Hospital's outpatient...

Evaluation of neurovascular anatomical variations in maxillary anterior region in cone beam computed tomography images

Introduction: Incisive foramen in the maxilla is the oral terminus of the nasopalatine canal. This region is important in implantology, Therefore, the aim of this study was to investigate the  neurovascular anatomical variations in the maxillary anterior region, observed on cone beam computed tomography (CBCT) images. Materials &Methods: In this cross-sectional study, maxillary CBCT ima...
