title: [Anatomical variations of landmarks in endoscopic surgery of the paranasal sinuses revealed by MRI imaging].
abstract: Continue development of endoscopic techniques of rinosinusal approach involves knowledge about the anatomy of this region, with a three-dimensional orientation before surgery, a therapeutic plan well thought, anticipating the gesture controller, taking into account the particularities of each case. Endoscopic surgical anatomic variants parts at this level can be well identified by imaging methods (CT, MRI). CT study of patients who are candidates for surgery Fess is on top, as the technique of choice. MRI is the imaging method to supply the CT data, providing a study carried out the normal anatomy and standard deviation of the numerous variants, single or in combination. This paper aims a randomized retrospective study of 120 MRI of the head and face region, to investigate and highlight the anatomical variations of structures at this level of impact and those with sinusitis etiopatologia, as well as those with operative risk (bleeding complications, ocular, vital risk) to determine the prevalence in the general population and have to compare the data with the literature. Using all sections (axial, sagittal and coronal) with the aid of different sequences (T1, T2, Flair and diffusion) allowed study of three-dimensional images of whole rhino-sinus-related pathology. Anatomic variations of surgical landmarks have investigated a wide range of expression, which are unique or associated with a complex architecture, with sufficient accuracy and visible on MRI. Their prevalence in the group studied was generally consistent with the literature studied.
