Neurotological emergencies: a narrative review.

INTRODUCTION

Vestibular symptoms, including vertigo, dizziness, and gait unsteadiness, are a frequent reason of urgent medical assistance. Their causes are numerous and diverse, including neurological, otorhinolaryngological, and systemic diseases. Therefore, following a systematic approach is essential to differentiate striking but benign conditions from others that can compromise the patient's life. This study is intended to review vestibular disorders from a practical perspective and provide guidance to physicians involved in the emergency care of patients with vestibular symptoms.

MATERIALS AND METHODS

A narrative review was performed, revisiting the main causes of vestibular disorders.

RESULTS

Based on the speed of onset, duration, and history of similar episodes in the past, vestibular disorders can be categorized into three syndromic entities (acute, recurrent, and chronic vestibular syndromes). The most representative conditions pertaining to each group were reviewed (including their diagnosis and treatment) and a practical algorithm was proposed for their correct management in the acute care setting.

CONCLUSIONS

Carrying out a correct categorization of the vestibular disorders is essential to avoid diagnostic pitfalls. This review provides useful tools for clinicians to approach their patients with vestibular symptoms at the emergency room.
