Exploring therapeutic alternatives: A review on the approach to smell disorders

Abstract

The senses play a crucial role in our connection with the environment and in our social interactions. Among them, smell stands out for its protective function against risks such as gas leaks, fires and spoiled food, in addition to its contribution to the development of memory and interpersonal relationships. Alterations in the sense of smell carry significant physical and psychological repercussions, with inflammatory pathology being the most common cause, although post-viral hyposmia secondary to SARS-CoV-2 has gained relevance during the pandemic.

The availability of effective treatments is crucial to addressing these conditions. In this literature review, we focus on current treatments for hyposmia and anosmia, as well as the evidence supporting them. According to the literature reviewed, the most effective treatment methods include olfactory training, omega-3 supplementation, and the use of nasal corticosteroid washes. Furthermore, the use of platelet-rich plasma emerges as a promising therapy for a specific group of patients.
