A dual-headed surgical instrument, comprising:

• an elongated handle portion extending along a longitudinal axis, the elongated handle portion having opposed first and second ends,
• wherein the first end has a first surgical tool head, said first surgical tool head comprising a flat surface having a semi-sharp peripheral edge and an opposing atraumatic face;
• wherein the second end has a second surgical tool head, said second surgical tool head comprising either a flat surface having a semi-sharp peripheral edge and an opposing atraumatic face or a concave elliptical surface having a semi sharp peripheral edge,
• wherein the first surgical tool head extends along a first tool axis, the first tool axis being angularly displaced from the longitudinal axis by 60°±2° such that the first surgical tool head is configured to reach an anterior cranial fossa of a patient,
• wherein the second surgical tool head extends along a second tool axis, the second tool axis being angularly displaced from the longitudinal axis by 150°±2° such that the second surgical tool head is configured to reach both a middle cranial fossa and a posterior crania fossa of the patient,
• wherein the first end of the elongated handle portion is curved with respect to the longitudinal axis,
• wherein the second end of the elongated handle portion is straight with respect to the longitudinal axis,
• wherein the first surgical tool head is attached the first end of the elongated handle portion that is curved with respect to the longitudinal axis, and
• wherein the second surgical tool head is attached the second end of the elongated handle portion that is straight with respect to the longitudinal axis.
