OBJECTIVE Surgical approaches to ambient cistern lesions are complex. We investigated the microanatomy of the transtemporal-transchoroidal fissure approach to the ambient cistern with emphasis on exposure of the posterior cerebral artery. METHODS Dissections were performed bilaterally in five silicone-injected cadaveric heads. Critical anatomic distances,(More)
OBJECTIVE To compare the angles of approach and area of exposure to the anterior communicating artery (AComA) complex associated with pterional (PT), orbitopterional (OPT), and orbitozygomatic (OZ) craniotomies before and after gyrus rectus resection. METHODS PT, OPT, and OZ craniotomies were performed on both sides of four heads, and the angles of(More)
OBJECTIVE We explored relevant regional microanatomy as it relates to the challenging anterior interforniceal (AIF) approach for removing hypothalamic hamartomas. METHODS Five silicone-injected cadaveric heads were dissected by use of frameless stereotactic navigation to reveal microanatomy and extent of exposure through the transcallosal AIF approach.(More)
OBJECT The authors quantitatively assessed the working areas and angles of attack associated with retrosigmoid (RS), combined petrosal (CP), and transcochlear (TC) craniotomies. METHODS Four silicone-injected cadaveric heads were bilaterally dissected using three approaches progressing from the least to the most extensive. Working areas were determined(More)
STUDY DESIGN Prospective observational study. PURPOSE To investigate the value of pain distribution in localizing appropriate surgical levels in patients with cervical spondylosis. OVERVIEW OF LITERATURE Previous studies have investigated the value of pain drawings in its correlation with various features in degenerative spine diseases including(More)
