Abstract

Objectives: The purpose of this prospective study was to check the value of smell disorders as a prognostic tool for COVID-19.
Background: Viruses that give rise to the common cold are well known to cause post-infectious loss of smell. The severity of post-viral anosmia is variable at its risk and duration of presentation.
Patients and Methods: The study is conducted on 100 patients suffering from CSF rhinorrhea who are admitted to Alexandria Main University Hospital for operative intervention from January 2018 to May 2021.
Results: Four hundred patients with positive PCR testing of COVID-19 but they had smell disorders were randomly included in this study. All patients were divided into two groups according to the severity of manifestations. Patients were scheduled for follow-up visit with smell test and computed topography to the chest. The mean age of studied group was 38.4 ± 11.8 years. 60.5% of studied cases were females and 39.5% of studied cases were males. The patients with mild manifestations were 81.25% and 18.75% of cases were presented with severe chest manifestations. 6.5% presented with anosmia after one month, and only 8.25% of patients presented with parosmia after one month and 341 cases showed improved smell disorders.
Conclusion: Olfactory manifestations for COVID-19 are common and should be added to suspected clinical criteria of COVID-19 particularly if nasal examination was non-significant.
