The effect of transnasal sphenopalatine ganglion blockade on pain, functional capacity, sleep, and depression in patients with fibromyalgia.

OBJECTIVES

The Sphenopalatine Ganglion (SPG) is the target of interventional procedures in musculoskeletal pain, especially headaches, due to its role in the autonomic nervous system. Our study aimed to investigate the effect of transnasal sphenopalatine ganglion blockade (SPGB) on pain, functional capacity, sleep, and depression in fibromyalgia patients.

METHODS

The hospital records of fibromyalgia patients who applied to the Algology outpatient clinic between January and May 2021, unresponsive to standard medical treatments, and underwent six sessions of bilateral transnasal SPGB at 10-day intervals were analyzed retrospectively. Numerical Rating Scale (NRS), functional capacity Fibromyalgia Impact Questionnaire (FIQ), sleep status Pittsburgh Sleep Quality Index (PSQI), and depression severity Beck Depression Inventory (BDI) data were collected during the treatment process.

RESULTS

The mean NRS score of the patients before the treatment was 8.1852±1.71053, compared with 6.2593±2.29703 after the treatment. The mean FIQ score of the patients before the treatment was 73.0359±13.55302, compared with 54.2507±16.1906 after the treatment. After the treatment, the pain score, functional capacity, sleep quality, and depression of the patients were statistically significantly different than pretreatment (p<0.001).

CONCLUSION

SPGB has been found to positively affect pain, functional capacity, sleep disorders, and depression in patients with fibromyalgia.
