Awake right hemisphere surgery effectively preserves speech and motor functions, particularly for left-handed patients or those with speech impairments. Intraoperative mapping enhances outcomes in these complex brain surgeries.

Area of Science:

  • Neurosurgery
  • Neurology
  • Neuroscience

Background:

  • Awake craniotomies are crucial for preserving eloquent cortex during brain surgery.
  • Right hemispheric lesions can present unique challenges, including crossed aphasia.

Purpose of the Study:

  • To investigate the indications and outcomes of awake right hemispheric brain surgery.
  • To analyze the effectiveness of intraoperative cortical mapping in these procedures.

Main Methods:

  • Retrospective review of 35 patients undergoing awake right hemisphere brain operations.
  • Intraoperative cortical mapping of motor and/or language function in 29 patients.
  • Analysis of preoperative indicators and postoperative functional improvements.

Main Results:

  • Preoperative speech impairment and left-hand dominance were key indicators for awake right-sided craniotomies.
  • 48.3% of patients had eloquent cortex representation identified.
  • Significant improvements were observed in motor function (41.1%), seizure control (68.7%), and headaches (77.7%).
  • All patients with preoperative speech difficulties showed improvement.

Conclusions:

  • Awake right-sided craniotomy is a valuable option for left-handed patients or those with right-sided lesions causing speech impairments.
  • Combining awake surgery with intraoperative cortical mapping effectively preserves speech and motor functions.
