Figure. Temporal Trends of Surgical IIH Treatments From 2016 to 2020.

Figure

(A) Percentage of shunt, VSS, and ONSF among all surgical IIH procedures over time; p values derived from χ2 analysis. (B) Percentage change of number of procedures from 2016 to 2020; p values derived from comparison number of each procedure as a proportion of total procedures between 2016 and 2020 using the Fisher exact test. IIH = idiopathic intracranial hypertension; ONSF = optic nerve sheath fenestration; VSS = venous sinus stenting.
