Filter by:The loss of the sense of smell, anosmia, can have profound effects on the lives of those who suffer from it. In our clinical practice, we have encountered several patients complaining of anosmia after recently undergoing surgery requiring cardiopulmonary bypass. We want to investigate this peculiar observation and determine if such a link exists. Thus far, there have been no similar studies published, and as such, no previous evidence on this matter. This study will help formalise and clarify these observations, empowering clinicians to better inform patients in the future; if cardiopulmonary bypass procedures do carry a risk of anosmia. This study may also give rise to further research into the matter.
The purpose of this study is to determine if a trial of directed high-dose nasal steroids improves residual smell loss in patients with chronic rhinosinusitis following sinus surgery. Other outcomes of this study include: identifying the differences in sinus airflow between patients who improve following nasal steroid treatment and those who do not, and to see if, in patients who improve following surgery, the improvement remains throughout follow-up.
Signal processing in the olfactory neuron could be influenced by inhibition of enzymes like phosphodiesterase. Pentoxifylline is a unspecific phosphodiesterase inhibitor. The hypothesis is that pentoxifylline could lead to increased sensitivity to odors.
