Introduction An anatomical study was conducted to test a modified C-shaped flap designed
for patients undergoing a keyhole approach and/or minicraniotomy for retrosigmoid …

Objective To investigate the impact on functional outcome and postoperative pain of a
modified C-shaped skin incision and muscle flaps in patients undergoing mini-craniotomy …

Chronic postoperative neuralgias and headache following retrosigmoid craniotomy can be
uncomfortable for the patient. We aimed to better elucidate the regional nerve anatomy in an …

Background: The retromastoid approach has been effective in exposing the
cerebellopontine angle for resection of a variety of lesions, including vestibular …

Methods: Six sides of three formalin-fixed latex-injected specimens were dissected under
microscopic magnification. A retrosigmoid craniotomy was performed by each of three …

Background The traditional retrosigmoid (RS) approach provides limited exposure of the
inferior compartment of the CPA, while radical skull base approaches are demanding and …

Introduction There are many reported modifications to the retrosigmoid approach including
variations in skin incisions, soft tissue dissection, bone removal/replacement, and closure …

The retrosigmoid approach (RS) approach is the workhorse of the posterolateral
neurosurgical techniques to access various posterior fossa structures and even extends into …

Background: In this video-abstract, we present a one burr-hole craniotomy for the upper
retrosigmoid approach developed in Helsinki Neurosurgery to access the lateral cerebellar …

Background The retrosigmoid approach (RSA) is one of the routes of choice to approach
tumors and vascular lesions of the cerebellopontine angle. Among different types of skin …
