Sphenopalatine ganglion block for postdural puncture headache: A review of current evidence

Although EBP remains the preferred treatment for severe PDPH, the SPG block is a viable alternative for mild-to-moderate cases, often allowing patients to postpone or avoid EBP. Comparative studies suggest that SPG block has a quicker onset than EBP, though in some cases, it provides shorter duration relief. Overall, the SPG block is a safe, effective, and readily accessible treatment for PDPH. Its minimally invasive nature and high success rate in providing rapid pain relief make it an excellent first-line alternative to more invasive procedures. Further large-scale, standardized randomized controlled trials are required to optimize protocols and fully integrate the SPG block into mainstream clinical practice.
