Sphenocath

At TMJ & Sleep Therapy Centre of San Diego, we utilize the SphenoCath® device for delivering sphenopalatine ganglion (SPG) blocks, an advanced procedure aimed at managing certain types of facial pain, headaches, and chronic migraines. The SPG is a collection of nerves located deep within the nasal cavity, which plays a key role in modulating pain in the head, face, and neck. The SphenoCath® device delivers anesthetic through the nasal cavity, effectively delivering an SPG block for conditions such as trigeminal neuralgia, cluster headaches, and chronic migraines without the use of needles, cotton swabs, or harsh meds. For most, the procedure is comfortable, while others may briefly feel a very slight nasal irritation. This technique is particularly effective for patients who have not responded well to other treatments or prefer a non-surgical approach to pain management. The patient may feel some temporary numbness in the nose or throat and should rest for a short period after the procedure.


The Device

The SphenoCath is composed of a semi-rigid ticothane, and tico-tungsten sheath (gray) with an inner, pliable catheter and hub (purple—shown extended, above).

  • The SphenoCath is a registered FDA Catagory-1 trans nasal drug delivery device.
  • The SphenoCath is specifically designed to facilitate the delivery of local anesthetic to the para-sympathetic, sympathetic, and V2 maxillary division of the head’s principle autonomic nervous system pathways.
  • The SphenoCath allows drug delivery access to the bilateral Sphenopalitine Ganglia (SPG), V2, and associated fibers involved with the entire SPG circuit.

The Procedure CPT 64999

With the patient in supine position, the device is inserted into the nasal cavity until reaching the superior aspect of nasal bone. (catheter not yet extended).

The device is then slightly withdrawn.

The inner catheter is extended, and the local anesthetic is delivered. The procedure is repeated in the other nostril, and the patient remains in place for 7-10 minutes to maximize mucosal absorption.

Benefits of using the SphenoCath® device in an SPG Block Procedure:

  • In-office procedure
  • Majority of patients experience immediate relief
  • Very low risk
  • Very high success rates
  • Safe for adults and children
  • Single use and disposable
  • Pain relief


Safety and Efficacy

Careful tracking of procedural endeavors throughout the US and beyond, demonstrates exceptional patient tolerance, and no reported severe adverse events or reactions.


  • Some patients may notice a metallic or bitter taste from the Lidocaine during the procedure.
  • Some patients may experience slight perceived difficulty swallowing, during the procedure, due to sensory numbness in the throat. (A water bottle with a bendable straw will be provided to reduce this sensation)
  • Some patients may experience mild nasal discomfort and/or mild nosebleeds.
