Abstract:
The ability to smell is commonly altered by head injuries. However, the nature, prevalence, prognosis and etiology of such alterations are poorly understood. Patients complaining of head-trauma and a related olfactory dysfunction typically have anosmia and rarely regain normal olfactory ability. Parosmia prevalences decreases over time in such patients, and damage to olfaction-related brain structures can be observed in most such patients using an appropriate MRI protocol. In this article, we review the recent knowledge about postraumatic anosmia.
