Abstract

Stereotactic surgery is a technique allowing the operation of an intracranial lesion without the need for craniotomy. Now stereotactic technique is widely used for aspiration of brain abscess or hemorrhage, biopsy of brain tumor and treatment of movement disorder etc. Because of the frame of stereotactic system, that is fixed on the scalp, laryngoscopic endotracheal intubation may be disturbed. So, in this case, we used laryngeal mask airway Proseal (PLMA(TM)) for maintenance of airway during stereotactic biopsy of brain tumor under general anesthesia. It was easily to insert PLMA(TM) using the introducer at once. The ventilation during the operation was not impeded at all time. There were not excessively changes of vital sign during general anesthesia. We think that PLMA(TM) may be a good alternative method for maintenance of airway during stereotactic surgery under general anesthesia.
