ABSTRACT
Objective. To determine general clinical characteristics and by Magnetic Resonance of patients sent to our service for valuation of paralysis of the facial nerve.Material and method. Retrospective cross sectional study in 30 patients with affection (paralysis) of the facial nerve. A clinical questionnaire was applied, later we took Magnetic Resonance images, which were analyzed by two expert Radiologists who determined the diagnosis.
Results. Of 30 patients, 12 were men and 18 women, the age average was 51,4 years. Evolution time of paretic facial symptomatology varied from a day after initiates the symptoms to five years later, with an average of 511 days. In 15 patients (50%) the central or peripheral origin of the paralysis was not established clinically, six patients (20%) presented central paralysis by clinical data and in nine patients (30%) the paralysis was peripheral; nevertheless, in no of these last ones were established if the affection were suprageniculated, supraestapedial, infraestapedial or infracordal. In 20 patients (66%) it was not possible to diagnose by Magnetic Resonance the origin of the paralysis of the facial nerve, in six patients (20%) the Magnetic Resonance images demonstrated supranuclear origin of the affection and in four patients (13%) peripheral alteration of the facial nerve was demonstrated.
Conclusion. It is difficult to establish clinically the anatomical location and nature of the facial nerve injuries, in atypical patients of facial paralysis, valuation by Magnetic Resonance must be considered to clarify the diagnosis and to improve the opportune handling and prognosis of the patient.
