“…Abuse of sweets, which causes weight gain, may advocate a state of low immunity, which may increase the incidence of other viral infections resulting in VN. The practice of working from home, frequently with insufficient facilities, leads to postural unhealthy habits that cause cervical pain or may provoke BPPV [ 24 ].…”

Background It has been postulated that COVID-19 has a substantial neuro-otological impact such as vertigo or dizziness that is rarely evaluated. The purpose of this research is to study the occurrence of vertigo (whether as presenting symptom or a sequela) and its etiological characteristics in patients with covid 19 infection and close contact. It is a cross-sectional study (convenient sample) conducted on patients that had a previous history of covid 19 infection and another group of contact individuals who presented with the sensation of vertigo. All the included participants underwent full neurological and otological examination, nasopharyngeal swab PCR to confirm COVID-19 infection and video nystgmograghy (VNG). Results it was included 44 participants, where 7 (15.9%) of the participants were post-COVID-19 patients and 37 (84.1%) were close contacts of COVID patients. It was found that 6(85.7%) of post-COVID-19 patients had vestibular neuritis (VN), and 1(14.3%) patient had Benign Paroxysmal Positional Vertigo (BPPV). 9(23%) of those in close contact had positive PCR for COVID infection, 6(66.7%) of them had VN, and the other 3 (33.3%) had BPPV. Conclusion Vertigo could be a possible complication or a presenting symptom in patients with COVID patients that is mainly attributed to peripheral vestibular dysfunction.

Background: As COVID19 is a pandemic disease with a variety of symptoms. It was a must to study these symptoms focusing on ENT symptoms both during the illness and post recovery.Objective: This study aimed to evaluate the prevalence of otolaryngological manifestations in COVID-19 patients. Methods: A non-random cross sectional observational study included 18 patients had COVID-19. They underwent otorhinolaryngology examination. Subjective methods were used for smell and taste and audiovestibular evaluation. PTA was performed in all frequencies to determine the type and level of hearing impairment.VNG was done to detect vestibular insults if present. Results: The sample collected showed that 14 (77.7%) patients felt dizzy. Regarding smell affection, 11(61.1%) patients had smell affection of varying degrees. Sore throat and dysphagia were reported in 55.5% of patients. Dysphonia was in 6 (33.3%). Also, generalized symptoms were present in 13 (72.3%). Tinnitus only was present in 7 patients (38.9%) with 57.2% of them had normal hearing level, while the rest (42.8%) had hearing loss. As regards PTA findings, hearing impairment was bilateral in 16.66%, unilateral in 22.2% and normal hearing was noted in 61% of cases. VNG revealed central affection in 2 patients (11.1%) only. Conclusion: Audiovestibular system can be affected by SARS-COV-2 resulting in sudden sensorineural hearing loss (SSNHL) and dizziness. No systematic research was done, so the real prevalence of COVID-19 related SSNHL and dizziness around the world is unknown. Further research needs to be done.
