Síntomas y signos de la hipofunción vestibular unilateral y bilateral / Symptoms and signs of unilateral and bilateral vestibular hypofunction

INTRODUCCIÓN Y OBJETIVO: La disfunción vestibular periférica implica a los órganos vestibulares o a los nervios vestibulares, produciendo una gran variedad de síntomas y signos clínicos. MÉTODO: Revisión narrativa. DISCUSIÓN: El otoneurólogo es el encargado de realizar una evaluación exhaustiva para llegar a identificar el trastorno que presenta el paciente que acude con vértigo o desequilibrio. La clave diagnóstica es la anamnesis profunda completada con un cuidadoso examen otoneurológico. Además, las nuevas tecnologías de estudio que han surgido en este campo permiten un cambio en la definición, caracterización y tratamiento de estas patologías. CONCLUSIONES: En la presente revisión narrativa se describirán los dos grandes grupos de deficiencia vestibular periférica: la vestibulopatía unilateral y bilateral

INTRODUCTION AND OBJECTIVE: Peripheral vestibular dysfunction involve the vestibular organs or the vestibular nerve producing a wide variety of symptoms and clinical signs. METHOD: Narrative revision. DISCUSSION: The otoneurologist is responsible for conducting an exhaustive evaluation to identify the pathology presented by the patient who has vertigo or imbalance. The key to the diagnosis is the deep history completed with a careful otoneurological examination. CONCLUSIONS: In the present narrative review, the two large groups of peripheral vestibular deficiency will be described: unilateral and bilateral vestibulopathy

Compensación vestibular / Vestibular compensation

INTRODUCCIÓN Y OBJETIVO: La compensación vestibular es el conjunto de procesos que se ponen en marcha cuando tiene lugar una lesión a nivel vestibular sea cual sea el origen y la magnitud de la misma. a vez establecida la lesión los mecanismos de compensación del daño son variados y se establecen diferentes líneas de actuación. Para conocer cómo mejorar el estado de nuestros pacientes es importante saber cómo funciona la compensación vestibular y a qué niveles podemos actuar para acelerar el proceso de recuperación. CONCLUSIONES: Es importante conocer los mecanismos de compensación vestibular para adecuar la terapia a cada paciente y así mejorar su calidad de vida

INTRODUCTION AND OBJECTIVE: Vestibular compensation is the term used to describe the mechanisms triggered when there is damage in the vestibular system regardless of its origin. When suffering from an injure in vestibular area there are a wide range of compensatory responses that will involve different approaches. In order to improve the quality of life for our patients and to correctly work with them to accelerate the restoration process it is important to become acquainted with how vestibular compensation works. CONCLUSIONS: Vestibular compensation mechanisms are important to adapt the therapy to each patient and thus improve their quality of life

Spontaneous cerebrospinal fluid leaks in the anterior skull base secondary to idiopathic intracranial hypertension.

Spontaneous cerebrospinal fluid (CSF) leaks represent a clinical entity in which CSF rhinorrhea occurs in the absence of any inciting event. Spontaneous CSF leaks are associated with elevated intracranial pressure (ICP) or have underlying idiopathic intracranial hypertension (IIH). We report a cohort of patients who have undergone nasal endoscopic repair for spontaneous CSF leaks. We review our perioperative complications and the effectiveness of the nasal endoscopic approach to repair spontaneous CSF leaks. Also, we examine the evidence correlating spontaneous CSF leaks and IIH and the role of decreasing ICP in the treatment of nasal spontaneous CSF leaks. A retrospective analysis of patients with nasal spontaneous cerebrospinal fluid leaks was performed. Data on the nature of presentation, patient body mass index, defect location and size, ICP, clinical follow-up, and complications were collected. Thirty-five patients had nasal spontaneous cerebrospinal fluid leaks with evidence of IIH's symptoms. The most common sites were the cribriform plate, the ethmoid roof, and sphenoid lateral pterygoid recess. All patients underwent endonasal endoscopic surgery to repair the defect. Postoperatively, all patients underwent lumbar drainage and acetazolamide therapy. Nasal spontaneous cerebrospinal fluid leaks represent a surgical challenge because of their high recurrence rates. The most important factor for obtaining a successful repair in these patients is reducing their intracranial pressure through nutritional, medical, or surgical means.
