Should anosmia and dysgeusia be a concern for oral and maxillofacial surgeons during the COVID-19 pandemic?

PURPOSE

Dysgeusia and anosmia have been liked to COVID-19 infection. The aim of this study is to study the prevalence of dysgeusia and anosmia in COVID-19 patients treated at the University of Florida Health Center and establish the odds of having an olfactory and gustatory disorder with a confirmed COVID-19 infection.

METHODS

This is a retrospective cross-sectional study utilizing the University of Florida Health Center patients' registry i2b2 platform to search for ICD 10 diagnoses of COVID-19 infection and taste and smell disturbances. We assessed the odds ratio for patients with dysgeusia and anosmia having a laboratory-confirmed COVID-19 infection using a logistic regression model adjusting for gender, race, age, and comorbidity conditions. P < 0.05 was deemed significant.

RESULTS

Out of 889 individuals that tested positive for COVID-19, 12.88% were diagnosed with taste and smell disturbances. The odds ratio for COVID-19 for people with dysgeusia and anosmia was 39.107. After adjusting for sex, age, and race, it was 41.9, 37, and 34.2, respectively.

CONCLUSION

Taste and smell disturbances in COVID-19 are not anecdotal. It is paramount that oral and maxillofacial surgeons include taste and smell disturbances in the history and physical examination as these symptoms are suspicious of active COVID-19 infection. Patients presenting with an olfactory and gustatory disorder should undergo further evaluations for COVID-19 infection and oral and maxillofacial surgeons should enhance the personal protective equipment used when treating these patients to prevent further spread of the infection and protect other healthcare members.
