Intranasal Platelet-Rich Plasma With or Without Topical Insulin for Post-Inflammatory Anosmia

This study evaluates whether adding topical insulin to intranasal platelet-rich plasma (PRP) improves smell recovery in adults with post-inflammatory anosmia. Participants will be randomly assigned to receive either intranasal PRP combined with topical insulin or intranasal PRP alone. Changes in olfactory function will be assessed over time to compare the effectiveness and safety of the two treatments.
