Clinical otorhinolaryngological presentation of COVID-19 patients in Saudi Arabia: A multicenter study

Assessment of anosmia/hyposmia in post-COVID-19 patients: a cross-sectional study in an eastern province of Saudi Arabia

Background and aim It has been shown that olfactory dysfunction is one of Coronavirus disease-2019 (COVID-19)common and puzzling symptoms that may persist weeks after the infection. This study aimed for the objective assessment of persisting olfactory dysfunction in post-COVID-19 patients. It also investigated the factors associated with the development of such symptoms in the Eastern Province of Saudi Arabia.

METHODS

A cross-sectional study that was conducted in the Department of Physiology, College of Medicine, Imam Abdulrahman bin Faisal University, Khobar, Saudi Arabia. One hundred and forty-seven participants were included in this study, and sixty of them agreed  to participate in the objective testing using the Connecticut Chemosensory Clinical Research Center (CCCRC) olfaction test.

RESULTS

There was a significant correlation between the following factors: (1) Persistence of anosmia/hyposmia and the time of onset of anosmia/hyposmia (P=0.015). (2) Persistence of anosmia/hyposmia and the duration of anosmia/hyposmia (P=0.012). (3) Duration of anosmia/hyposmia and the duration of COVID-19 symptoms (P=0.010). Interestingly, there was a significant association between the subjective participants' claim of anosmia/hyposmia and the score of their objective assessment (P=0.026).

CONCLUSION

The current study demonstrated that post-COVID-19 participants with delayed onset of anosmia/hyposmia and/or longer duration of either anosmia/hyposmia or COVID-19 symptoms were prone to have persistent olfactory dysfunction. Further studies are necessary to uncover the underlying pathophysiology and management of this olfactory dysfunction in COVID-19 patients.

Long-Term Outcomes of COVID-19 Otolaryngology Symptoms in Saudi Arabia

OBJECTIVES

The objectives of the study are to measure the prevalence of the most common symptoms and different long-term otorhinolaryngology manifestations among COVID-19-positive patients in Saudi Arabia.

METHODS

This is a cross-sectional study. Data were collected using a Google form questionnaire sent to the study sample. The data were entered and then analyzed using SPSS version 25.0 (IBM Corp, Armonk, NY).

RESULTS

A total of 13,530 COVID-19-positive adult patients were enrolled in the current study. The most reported initial symptom was fever (53.3%) followed by headache (49.3%), sore throat (48.9%), nasal congestion, rhinorrhea (42.1%), and loss of smell and/or loss of taste (37.8%). Regarding the continuation of the symptoms, vertigo was mentioned by 5852 (43.3%) followed by fever (16.1%) and blocked ear sensation (15.6%).

CONCLUSION

The most commonly reported initial symptom was fever followed by headache. Interestingly, vertigo is a frequent long-term complication after a COVID-19 infection. Other otology-related symptoms include hearing loss and ear blockage, while rhinology and upper airway-related symptoms were less frequent in the long term after the acute phase of the infection.

Ear, nose, and throat manifestations of COVID-19 and its vaccines

Coronavirus disease 2019 (COVID-19) is a highly infectious disease and was designated a pandemic by the World Health Organization (WHO) on March 11, 2020. There are no classical manifestations of the disease. The most prevalent symptoms include fever, cough, dyspnea, myalgia and headache. The main route of transmission of the severe acute respiratory syndrome coronavirus-2 is through the upper respiratory tract. Therefore, it is not strange to find different ear, nose and throat (ENT) symptoms in individuals infected with this virus. Olfactory dysfunction is a common feature of COVID-19; either it is the only presenting symptom or it accompanies other manifestations of the disease. Other otolaryngological features such as sudden sensorineural hearing loss (SSNHL), dysphonia, nasal obstruction, sore throat, etc. are less frequent manifestations of COVID-19. These features, in addition, to being presented early in the disease process, certain long-standing symptoms like parosmia, dysphonia, and persistent deafness, are other characteristics of the disease. Geographical variation in otorhinolaryngological prevalence is another problem with this debilitating disease. Local and systemic adverse effects (local site injection pain, fever, myalgia, headache, and others) of the COVID-19 vaccines are more frequent than otolaryngological side effects (anosmia, hyposmia, Bell's palsy, SSNHL, etc.). We aimed in this review to summarize the early and persistent ENT symptoms of COVID-19 or after the various COVID-19 vaccines.
