PRP Therapy in Torrance and El Segundo, CA

Experiencing a loss of smell (anosmia) can profoundly impact your safety, nutrition, and overall quality of life. Whether your sense of smell vanished following a viral infection like COVID-19 or disappeared due to a head injury or concussion, the frustration of feeling disconnected from the world is deeply valid. If traditional treatments like olfactory training or steroid rinses haven’t brought your senses back, platelet-rich plasma (PRP) therapy offers a revolutionary, clinically proven path to recovery. As an advanced, in-office treatment, PRP harnesses your body's own natural healing mechanisms to repair and regenerate the delicate nerves responsible for your sense of smell.

The olfactory nerve is unique—it is the only nerve in the human skull capable of regenerating itself. However, two primary culprits can severely damage this pathway and stall natural recovery:

• Post-Viral Damage: SARS-CoV-2 (COVID-19) and other common cold and flu viruses aggressively attack the supporting "sustentacular" cells surrounding your smell nerves, leaving the neurons starved and dormant
• Traumatic Brain Injuries (TBI): Head trauma can physically pull, stretch, or shear the delicate nerve fibers as they pass through the skull base into the nose

Platelet-Rich Plasma is an autologous (derived from your own body) treatment. By isolating and concentrating the platelets from a small sample of your blood, we create a solution packed with powerful signaling proteins and natural growth factors. When carefully placed into the olfactory cleft (the upper nasal cavity where smell detection occurs), these growth factors act like regenerative signals for your nerves in order to:

• Upregulate healing and reduce deep-seated tissue inflammation
• Stimulate neuroregeneration, prompting dormant or damaged olfactory neurons to grow and reconnect

You don't have to take our word for it; PRP therapy for smell loss is backed by rigorous, gold-standard medical research.

The Landmark Stanford University Study (Post-Infection & COVID-19)

• 12.5 Times Higher Likelihood of Recovery: Patients who received intranasal PRP injections were 12.5 times more likely to show significant improvement in their sense of smell compared to those who received a placebo.
• Long-Term Trajectory: A subsequent follow-up study published by Dr. Patel’s team in early 2025 demonstrated that the therapeutic benefit continues to climb, moving from a 12-fold advantage at 3 months to 15 times higher odds of improvement at 1 year.

Breakthrough Data for Head Trauma Patients

For years, patients who lost their smell from physical injuries had very few medical options. However, a landmark study published by Dr. Jerome R. Lechien in Otolaryngology–Head and Neck Surgery investigated patients suffering from persistent anosmia due to head trauma.

• 67% Success Rate: Even though participants had suffered from traumatic smell loss for an average of nearly 5 years, two-thirds (67%) of patients reported significant improvement after receiving PRP treatment.
• Superior to Smell Training Alone: Patients utilizing PRP achieved clinically meaningful improvements that drastically outperformed olfactory training on its own.
