ABSTRACT
OBJECTIVE:
This study aimed to study methods for protecting the language areas during tumor surgery in Mandarin-Cantonese bilinguals (MCBs). MATERIALS ANDMETHODS:
Eleven MCB patients were positioned for awake surgery with the purpose of preserving both of their language proficiencies. All the exposed cortices were electrically stimulated 1 cm x 1 cm with anelectrode, and all the positive sites of stimulation were recorded for analyses, the tumor resection point was limited by 1cm distant from the language areas identified by electrical stimulation.RESULTS:
All patients had at least one language area identified; a total of 154 points were stimulated, with 22 positive points (14.3%), including five specific language areas, which all resulted in simple anomiain either language when stimulated. Among these, three were specific to Mandarin (1.9%), whereas two were specific to Cantonese (1.3%).CONCLUSIONS:
In proficient MBCs, areas specific to each language exist. Thus, performing intraoperative bilingual tasks to locate these language areas is necessary in order to preserve language function.
