Clinical Scorecard: Language Evaluation and Feasibility of Awake Craniotomy in Deaf Individuals: A Systematic Review of Communication Techniques and Outcomes

At a Glance

Key Highlights

• Awake craniotomy enables maximal tumor resection while minimizing neurological deficits through real-time functional mapping.
• Hearing impairment poses unique communication challenges intraoperatively, especially for sign language users due to visuomotor language processing.
• Tailored communication strategies including sign language interpreters and alternative technologies can facilitate feasibility of awake craniotomy in deaf patients.

Guideline-Based Recommendations

Diagnosis

• Select candidates with documented hearing impairment and assess communication capacity preoperatively.
• Evaluate language modality (sign language vs oral communication) and potential cortical reorganization related to deafness.

Management

• Implement individualized intraoperative communication strategies involving sign language interpreters or alternative communication technologies.
• Preserve bimanual dexterity and consider patient positioning to accommodate sign language use during mapping.
• Use direct electrical stimulation mapping tailored to distinguish motor from linguistic deficits in sign language users.

Monitoring & Follow-up

• Continuously assess patient’s ability to comprehend and respond during cortical stimulation.
• Monitor for neurological changes that may affect communication or motor function intraoperatively.

Risks

• Potential misinterpretation of motor deficits as language errors in sign language users.
• Communication barriers may increase risk of unrecognized intraoperative discomfort or neurological symptoms.
• Limited evidence base and lack of standardized protocols may affect safety and efficacy assessments.

Patient & Prescribing Data

Hearing-impaired patients undergoing awake craniotomy for brain lesion resection

Case reports suggest technical feasibility with tailored communication support; however, data are sparse and heterogeneous, limiting definitive conclusions.

Clinical Best Practices

• Preoperative planning should include detailed language and communication assessment specific to hearing impairment.
• Intraoperative paradigms must be adapted to the patient’s primary language modality, ensuring reliable bidirectional communication.
• Engage multidisciplinary teams including sign language interpreters and neuropsychologists to optimize mapping accuracy.
• Maintain flexibility in surgical setup to preserve hand function and visual access for sign language communication.
• Recognize and address ethical considerations related to equitable access to awake neurosurgical procedures for hearing-impaired patients.
