Abstract

The sphenopalatine ganglion (SPG) block has been utilized to treat a wide variety of pain disorders. Postganglionic parasympathetic, sympathetic neurons, and the somatic sensory afferents can all be blocked by an SPG block. We examine the SPG anatomy, the techniques of blockade and the vast spectrum of conditions and indications for SPG block for pain relief.

SPG block is an easy, safe and cost-effective method of management of acute, chronic and breakthrough pain which provides immediate relief and minimal side effects. It can be performed in a hospital or surgery center, clinic, office, ER department or at home. It is presently an underutilized and overlooked tool in pain therapy that should be more widely used.
