We report the morbidity associated with long-term seizure monitoring in 95 patients implanted with epidural strip electrodes.  Subtemporal epidural strip electrodes were placed through bilateral temporal craniectomies, using the standard approach to the Gasserian ganglion.  The silastic strip electrodes had four to six electrode contacts.  Twelve patients also had additional subdural strips placed.  Mean number of strip electrodes per patient was 5.3 strips (range 4-8).  Mean duration of implantation was 5.1 days (range 2-11).  Complications included epidural hematoma (1.1%), epidural fluid collection (2.1%), and cranial nerve injury (9.5%), for a total morbidity of 12.7%.  Nine patients developed transient cranial nerve injuries (three V, seven VII).  In five patients, cranial nerve injuries were mild and resolved in 2-8 weeks.  Four peripheral VIIth nerve injuries persisted to a mild degree after 3-month follow-up.  Nine complications occurred with the first 41 implantations during the first 5 years of this series; only four complications were associated with the 54 subsequent implantations in the last 4 years.  The morbidity of epidural implantations was low, and no significant permanent morbidity occurred.
