Summary
Post-COVID syndrome can affect hearing and balance. This study found common issues like gradual hearing loss, tinnitus, and vertigo in patients recovering from SARS-CoV-2 infection.
Area of Science:
- Otolaryngology
- Infectious Diseases
- Neurology
Background:
- The SARS-CoV-2 virus has been linked to a variety of post-infection complications.
- Audiovestibular symptoms, including hearing loss, tinnitus, and vertigo, have been anecdotally reported following COVID-19.
Purpose of the Study:
- To analyze patients diagnosed with audiovestibular post-COVID syndrome.
- To identify the most characteristic and common audiovestibular findings in these patients.
Main Methods:
- Analysis of 87 patients (aged 20-86) presenting with persistent audiovestibular complaints (>3 months) after SARS-CoV-2 infection.
- Evaluation of hearing loss, tinnitus, and vertigo symptoms.
Main Results:
- High-frequency hearing loss (4-6 kHz) was the most common finding, affecting 52 patients bilaterally.
- Tinnitus was reported by 73 patients (68 unilateral, 5 bilateral), with 61 experiencing new-onset symptoms.
- Vertigo occurred in 9 patients, all new-onset; acute sensorineural hearing loss was noted in 4 patients during infection, with no complete recovery.
Conclusions:
- Audiovestibular post-COVID syndrome is a recognized condition.
- Further research with larger cohorts and longer follow-up is necessary to understand the long-term effects and potential recovery of the audiovestibular system.

01:29The Vestibular System
39.6K
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

01:15Equilibrium and Balance
4.7K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

Post-traumatic stress disorder (PTSD) is a psychiatric condition that arises following exposure to traumatic events such as natural disasters, forced displacement, or severe accidents. It significantly impairs individuals' ability to cope with daily activities and disrupts their emotional and psychological equilibrium.
Symptoms and Behavioral Manifestations
A spectrum of distressing symptoms characterizes PTSD. Recurrent flashbacks, where individuals involuntarily relive traumatic events,...

A thorough health history and physical assessment are essential for identifying cardiovascular disease (CVD) symptoms and distinguishing them from other health issues.
Initial Enquiry
Ask the patient about their primary concern and thoroughly explore all reported symptoms.
Medical History
Investigate past illnesses affecting the cardiovascular system, such as angina, anemia, rheumatic fever, congenital heart disease, stroke, thrombophlebitis, dysrhythmias, varicosities

01:22Pathophysiology of Vomiting
449
Vomiting is a complex physiological response to expel harmful or irritating substances from the body. It's a defensive mechanism triggered by stimuli like poisons, microbial toxins, cytotoxic drugs, and mechanical abdominal distension. The process is centrally coordinated by the vomiting (or emetic) center located in the medulla of the brainstem. This area, rich in muscarinic M1, histamine H1, neurokinin 1 (NK1), and serotonin 5-HT3 receptors, coordinates the act of vomiting through...

Pleural Effusion Overview
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
