Abstract
Infection by SARS-CoV2 (the initial name was 2019-nCOV)
causes Coronavirus Disease (COVID-19) which is transmitted through
large droplets generated during coughing and sneezing by either
symptomatic patients or asymptomatic people (Li et al., 2020).
The most commonly affected organ system by COVID-19 is the
pulmonary system (Chen et al., 2020). Extrapulmonary organs are
also affected by corona virus causing extrapulmonary manifestations
including Audio-vestibular symptom: Sensorineural hearing loss
(SNHL) is the most frequent audio-vestibular symptom described,
occurring alone or in association with tinnitus and vertigo. The
etiopathogenesis of the inner ear disorders related to COVID-19
infection is still poorly understood. (Fancello, 2021)
This case control study was conducted to assess audio vestibular
manifestation in COVID-19 patient post-infection at Menoufia
University Hospital and mit-khalaf hospital,
The study included (500) patients who were attending
Audiology Unit with established diagnosis of COVID-19 based on
classic clinical and laboratory features from January 2021 to January
2023.
Subjects included in this study were divided into 3 groups;
Control group: consisted of (500) normal subjects of normal
individual, not complaining of dizziness or hearing loss in the age
range (18-60) years. Study group (COVID-19 cases group): consisted
of 500 subjects in the age range (18-60) years, with exclusion of
patients suffering from chronic disease and smokers. vaccinated group
consisted of 200 subjects in the age range (18-60) years, with no
previous history of COVID-19 infection.
All COVID-19 patients in the study group were subjected to the
following: full history taking : Onset of COVID infection , Method of
diagnosis, Duration of infection , Site of treatment: at home – at
hospital – ICU addmition , Use of chloriqine in treatment protocol and
duration of treatment, Sensation of aural occlusion , Sensation of
hearing loss: sudden or gradual – unilateral or bilateral , Treatment of
hearing loss by corticosteroid , Duration between onset of infection
and hearing loss , Sensation of tinnitus: continuous or intermittent –
unilateral or bilateral , Duration between onset of infection and tinntus
, Dizziness (duration – onset after COVID – falling attake- specific
position), Vaccinated or not>, If vaccinated: type of vaccine- any
audiovestibular manifestation after vaccine.
