Sphenopalatine blocks have been used to treat pain for more than 80 years. Anecdotal support for sphenopalatine ganglion blocks has been very strong in those who believe in the technique, but the research results have been inconclusive. Therefore, a double blind, placebo-controlled study was performed on 61 patients, 42 with fibromyalgia and 19 with myofascial pain syndrome. Pain was measured using visual analogue scales prior to treatment, during treatment, and 28 days after the treatment. Headaches were evaluated in frequency and location prior to and after treatment. Sphenopalatine ganglion blocks were performed under direct vision using 4% lidocaine and sterile water as a placebo. Analysis of the results showed no statistical differences between the lidocaine and the placebo groups.

Background: It is generally accepted that the greater palatine nerve and artery supply the palatal mucosa, gingiva, and glands, but not the bone or tooth adjacent to those tissues. When the bony palate is observed closely, multiple small foramina are seen on the palatal surface of the alveolar process. The authors hypothesized that the greater palatine nerve and artery might supply the maxillary teeth via the foramina on the palatal surface of the alveolar process and the superior alveolar nerve and artery.

Despite advances in procedural techniques and equipment, postdural puncture headache (PDPH) remains a serious complication of labour epidural analgesia after accidental dural puncture (ADP). Often considered a temporary inconvenience, PDPH can be debilitating in the short term. It can also be associated with chronic manifestations and serious complications.

Article Synopsis
- * A case is presented where a patient with severe PDPH after a cesarean section experienced immediate pain relief using a sphenopalatine ganglion block (SPGB), a treatment not often performed by obstetricians.
- * The article suggests that SPGB may be a safe and effective alternative to the traditional epidural blood patch for managing PDPH, offering obstetricians a non-invasive treatment option for their patients.
