ALFONSO MUNOZ, Eulalia. Relation between the cranial base and the electro-nystagmography. Rev Cubana Cir [online]. 2011, vol.50, n.4, pp.423-430. ISSN 0034-7493.

Introduction: nowadays, the electro-nystagmography is used for diagnosis; it is the process by which it is possible to register the position and movement of ocular eyeball to identify the changes in the electric field around the eye in modifying its position. Objective: to assess the usefulness of the electro-nystagmography in comparison with the traditional vestibular test for topographic diagnosis of auditory sequelae present in the patients presenting with cranial base fracture. Methods: a cross-sectional, analytical and observational study was conducted in the "Dr. Carlos J. Finlay" Military Hospital from January, 2006 to January, 2008. Universe included 210 patients divided into two groups: a study group with vestibular auditory sequealae after a fracture of cranial base and a control group consisting of healthy subjects. Results: dizziness was the symptom present in the 100 % of patients. From the total of 118 cases with positive electro-nystagmography, 47 (39.8 %) had negative results in the vestibular test. Conclusions: the electro-nystagmography was positive en most of study cases with a high sensitivity demonstrating that cases presenting with labyrinth weakness and directional predominance were not diagnosed by means of traditional vestibular test.
