Can Stellate Ganglion Block Therapy Cure Allergic Rhinitis?

Allergic rhinitis

Hello Dr.
Hong: I previously read about a treatment called "stellate ganglion block" for allergic rhinitis.
Can this therapy provide a cure? Are there any risks associated with the procedure? Thank you!

Hello, the surgical method you mentioned is not recognized as a standard treatment for allergic rhinitis in Western medicine.
This treatment approach has been primarily advocated by Japanese scholars, and it seems that only Dr.
Jan Liao-Ming-Yi in Taiwan performs this type of surgery.
However, I have not found any formal academic papers on this topic.
I do not have personal experience with this surgery, but I have reviewed the literature, which suggests it may improve immune function and blood circulation, potentially alleviating symptoms of rhinitis.
Nevertheless, allergic rhinitis is caused by the interaction of environmental factors and individual constitution, so it is crucial to focus on avoiding allergens in treatment.
As for the risks associated with this treatment, they include: 1.
Hoarseness; 2.
Local numbness (weakness in the neck and upper limbs); 3.
Convulsions / local anesthetic toxicity; 4.
Total spinal (intrathecal injection); 5.
Pneumothorax; 6.
Swallowing difficulties; 7.
Epidural block / subdural block; 8.
Neck and mediastinal hematoma, airway obstruction leading to death; 9.
Prolonged Horner's syndrome; 10.
Infection.
The estimated incidence of these complications is approximately 1.7 per 1000.

Stellate Ganglion Block (SGB) therapy is an emerging treatment that has garnered attention for its potential benefits in managing various conditions, including allergic rhinitis. However, it is essential to clarify that while SGB may provide symptomatic relief for some patients, it is not considered a definitive cure for allergic rhinitis.

Allergic rhinitis is primarily an immune response to allergens, such as pollen, dust mites, or pet dander. The condition is characterized by symptoms like nasal congestion, sneezing, itching, and runny nose. Traditional treatments include antihistamines, nasal corticosteroids, and allergen avoidance strategies. In some cases, immunotherapy may be recommended to help desensitize the immune system to specific allergens.

The stellate ganglion is a collection of nerves located in the neck that is part of the sympathetic nervous system. The SGB procedure involves the injection of a local anesthetic into the stellate ganglion, which can lead to a temporary blockade of sympathetic nerve activity. This blockade may help reduce inflammation and improve blood flow, potentially alleviating symptoms associated with allergic rhinitis.

Research on the effectiveness of SGB for allergic rhinitis is still limited, and while some studies suggest that patients may experience symptom relief, the results are not universally applicable. The therapy may be more effective for certain individuals, particularly those with coexisting conditions like chronic pain or anxiety, where sympathetic nervous system activity plays a significant role.

Regarding the safety of the procedure, SGB is generally considered safe when performed by an experienced practitioner. However, like any medical intervention, it carries potential risks. These may include:
1. Infection: As with any injection, there is a risk of infection at the injection site.

2. Nerve Injury: Although rare, there is a possibility of damaging surrounding nerves during the procedure.

3. Hematoma: Bleeding can occur at the injection site, leading to a hematoma.

4. Transient Symptoms: Patients may experience temporary side effects such as hoarseness, difficulty swallowing, or a sensation of heaviness in the arm on the side of the injection.

It is crucial for patients considering SGB for allergic rhinitis to have a thorough discussion with their healthcare provider about the potential benefits and risks. Additionally, they should explore all available treatment options for allergic rhinitis, as SGB may not be suitable for everyone.

In conclusion, while Stellate Ganglion Block therapy may offer some symptomatic relief for allergic rhinitis, it is not a cure. Patients should weigh the potential risks and benefits and consider traditional treatment options that have a more established efficacy profile. Consulting with an allergist or an ear, nose, and throat (ENT) specialist can provide further insights into the most appropriate management strategies for allergic rhinitis.
