Since Yasargil's report, most neurosurgeons operate on middle cerebral artery(MCA)
aneurysms through frontotemporal(pterional) bone flap under large skin incision which
could result avoidable complications of facial nerve damage. temporal muscle atropy,
paresthesia along incision scar and cosmetic bony defect. After careful review of detailed
facial nerve anatomy, the author has developed a less invasive approach involving 8cm
mini skin incision starting from 1.5cm above zygomatic arch, 1.5cm inside the anterior
temporal hair line to upward 4-5cm and then curving forward 3cm length around 9cm
above supraorbital ridge. Then, about f 5cm mini-bone flap centered on pterion is made.
After reflection of round dural flap, dissection of sylvian fissure was proceeded from
just lateral end of limen insula, where middle cerebral artery(MCA) bifurcation or
M2 segment was deeply located. The author has operated on consecutive
18 cases of MCA aneurysms using this minicraniotomy from 1996 to 1998 which
provided sufficient working area enough not only for surgeon's free hand motion
including multiple temporary clippings at one field but also inspection for other anterior
circulation and posterior circulation systems Hunt-Hess Grads for these patients were 17
cases of Grads ¥± and 1 case of Grade ¥°. Mean age of patients was 52.9 years old.
There were 15 males and 3 females. Excellent postoperative neurological conditions were
achieved without any morbidity or mortality. This approach is especially recommendable
for patients wish good neurological status for being less invasive anti more convenient
method.
