Filter by:Persistent smell loss that can include diminished or distorted smell function is a common symptom of long COVID syndrome. There are limited treatment options for long COVID-related smell loss. This study aims to determine the efficacy of two at-home treatments, smell training and non-invasive trigeminal nerve stimulation. This study requires participants to conduct daily at-home treatment sessions, attend three in-person study visits at the MUSC Department of Psychiatry and Behavioral Sciences, and complete electronic questionnaires over the 12-week trial, and again at the six-month timepoint. Participants in this trial may benefit directly with an improvement in sense of smell. However, participation may also help society more generally, as this study will provide new information about long COVID-related smell loss and its treatment.
- Causes of olfactory dysfunction can be classified into conductive and sensorineural causes. - Conductive causes are mainly due to structural nasal problem, which can be treated by nasal surgery - Sensorineural causes included post-infection, post-head injury, post Head and Neck irradiation and other central nervous system diseases. - Olfactory Training is well established treatment for sensorineural olfactory dysfunction in foreign countries. - Olfactory Training by neurological chemosensory stimulation using aromatic substances delivered via electronic portable aromatic rehabilitation (EPAR) diffuser was proved to be effective treatment in COVID-19 related olfactory dysfunction in recent Hong Kong study. - However, there is a lack of local study on the effect of Olfactory Training in other non-COVID-19 sensorineural causes of olfactory dysfunction in Hong Kong population.

Omega-3 supplementation has been shown to have neuroprotective and potentially anti-inflammatory properties in both central and peripheral nerve injuries. The investigators are studying to see if omega-3 supplementation will affect olfactory (smell) function in patients with olfactory dysfunction following endoscopic removal of pituitary tumors.
