Biometrics ethmoid by Computed Tomography

Abstract

Introduction: The ethmoid is a structure that has become relevant for anatomists, clinicians, neurosurgeons and otolaryngologists due the great development of endoscopic surgical techniques and multiple anatomic variants. Aim: This work was developed with the goal of establishing in our sample studied, depth of ethmoid roof, predominant by gender; frequency with which symmetry in ethmoid roof is presen- ted, and frequency with which supraorbital cells is in sample studied. Finally, the study is aimed to establish percentages by gender, the dimensions of the ethmoid on adult population. Material and methods: The cross-sectional, descriptive observational study in which retrospective review was performed consecutively, tomographic studies of the paranasal sinuses in axial, coronal and sagittal on patients over 20 years old at the Radiology De- partment of the Hospitals, Clinics, IPS, Regional in Luque, Iribas Clinical Institute, and Calvo Radiological Institute. Results: The studies performed revealed that the depth of the ethmoid roof was Keros II in both genders and both nostrils, the symmetry was found in 60%, the supraorbital cells were found in 27.5% of both cases. Conclusions: Measurements by computed tomography in ethmoid bone of patients who participated in this study do not differ from the measurements performed by other authors.
