Official title
Intranasal Injection of Platelet-rich Plasma Versus Saline for Treatment of Olfactory Dysfunction
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This randomized clinical trial will evaluate the benefit of platelet-rich plasma (PrP) in the treatment of olfactory dysfunction. PrP can be isolated from a patient's own blood and has been found in previous studies to have anti-inflammatory and pro-regenerative properties. It has been used across multiple specialties, such as Orthopedics, Facial Plastics, Dermatology, Neurology in injected form to treat a wide variety of tissues to encourage the body's inherent regenerative capacity. The investigators have completed a pilot study here evaluating it's use in olfactory loss which demonstrated safety and also suggested efficacy. Therefore, the investigators aim to assess the ability of PrP to improve olfactory function in patients with decreased sense of smell.
