C-Shaped Incision for Lateral Suboccipital Approach: Anatomical Study and Clinical Correlation

Abstract

Objectives: The standard incision for lateral suboccipital approaches has been the classic “reverse hockey stick.” Although that incision provides ample exposure, concern has been raised that excessive muscle dissection and skin elevation might lead to accumulation of cerebrospinal fluid (CSF) under the flap with increased risk of CSF leak. Using the C-shape incision for lateral suboccipital approaches can minimize the amount of muscle dissection and still provide optimal exposure and surgical outcomes. Describing the real advantages and safety of this technique and generalizing the use of it can provide the general neurosurgeon with a more familiar incision and less morbid approach for lesions in this area.
