Managing Trigeminal Neuralgia Pain with SPG Blocks

Trigeminal neuralgia is often described as one of the most intense types of facial pain a person can experience. Even simple activities like brushing your teeth, talking, or feeling a light breeze can trigger sudden, electric-shock–like discomfort. For those living with this condition, finding consistent relief can feel overwhelming. At TMJ & Sleep Therapy Centre of San Diego, innovative, non-surgical solutions such as SPG blocks offer new hope for managing trigeminal neuralgia pain safely and effectively.
 

What Is Trigeminal Neuralgia?

Trigeminal neuralgia (TN) is a chronic pain condition that affects the trigeminal nerve - the fifth cranial nerve responsible for sensation in the face. This nerve has three major branches that transmit sensations from the forehead, cheek, and jaw to the brain.

When the trigeminal nerve becomes irritated or compressed, it can misfire, sending sudden bursts of intense pain signals. Episodes may last seconds to minutes and can occur in rapid succession. The pain is often described as stabbing, burning, or shock-like and typically affects one side of the face.
 

What Causes Trigeminal Neuralgia?

There are several possible causes of trigeminal neuralgia, including:

• Blood vessel compression pressing against the trigeminal nerve
• Aging-related changes in nerve structure
• Multiple sclerosis, which can damage nerve insulation (myelin)
• Facial trauma or prior surgery
• Tumors or structural abnormalities, though these are less common

In some cases, no clear cause is identified. Regardless of the origin, the result is the same: a hypersensitive nerve that reacts intensely to even minor stimulation.
 

Traditional Treatment Challenges

Conventional treatments for trigeminal neuralgia often begin with prescription medications designed to calm nerve activity. While medications may reduce symptoms for some individuals, they can also cause unwanted side effects such as drowsiness, dizziness, or cognitive changes.

In more severe cases, surgical interventions may be considered. However, surgery carries risks and may not be appropriate for every patient. Many individuals seek alternatives that are less invasive yet still effective in reducing pain intensity and frequency.
 

A Targeted Approach: SPG Blocks

At TMJ & Sleep Therapy Centre of San Diego, we offer sphenopalatine ganglion (SPG) blocks using the advanced SphenoCath® delivery system. This modern technique focuses on a key nerve center located deep within the nasal passage known as the sphenopalatine ganglion. This cluster of nerves plays an important role in transmitting and regulating pain signals in the face, head, and neck.

By applying a local anesthetic directly to this nerve center through the nasal cavity, an SPG block can help interrupt pain pathways associated with trigeminal neuralgia, cluster headaches, and chronic migraines.
 

How the Procedure Works

The SphenoCath® system allows for precise placement of anesthetic without the need for needles or uncomfortable cotton-tipped applicators. The medication is delivered gently through the nasal passage to reach the targeted nerve cluster.

Most patients find the procedure to be well tolerated. Some may notice mild nasal sensitivity during the process. Temporary numbness in the nose or throat can occur afterward, which is expected and typically short-lived. Patients are advised to relax briefly following the procedure before resuming normal activities.
 

Find Relief from Facial Nerve Pain

Trigeminal neuralgia can be debilitating, but effective, minimally invasive treatment options are available. SPG blocks delivered with advanced technology offer a focused way to calm overactive pain pathways without surgery or heavy reliance on medications. For many patients, this innovative approach provides a renewed sense of control and comfort.
