While in supratentorial hemispheric stroke, the size of the bone flap has been the subject of many studies and ample debate, no studies have been conducted to determine the optimal size of the bone flap to be removed in SDC.  \nResearch question: To determine the optimal size of SDC in ischemic cerebellar stroke.  \nMethods: This is a multicentric retrospective study of patients undergoing SDC for ischemic cerebellar stroke. SDC size was determined in two perpendicular planes on early postoperative CT scans: (a) maximal lateral extension (L) and (b) maximal craniocaudal extension (CC) in cm. The primary endpoint was functional outcome according to modified Rankin Scale (mRS) at three months. Secondary outcome was mortality at three months, as well as surgical complications.  \nResults: A total of 88 patients were included in the final analysis. The mean L diameter of the SDC analyzed was 7 cm (SD 1.5), whereas the mean CC diameter was 4.4 cm (SD .8). When dichotomizing patients based on a threshold of L ≥ 6.5 cm, favorable outcome was more likely in the group with L ≥ 6.5 cm (OR = 3.23, 95%CI 1.02–10.56, p = .045). No statistically significant differences were observed in mortality at three months (OR =.66, 95%CI .24–1.78, p = .40).  \n* Corresponding author.
