Trigeminal neuralgia as a complication after anterior temporal lobectomy: A case report

Temporal lobe epilepsy (TLE) is one of the most common forms of focal epilepsy. Anterior temporal lobectomy (ATL) leading to high rate of seizure freedom is a safe and well-established procedure in TLEs. Cranial nerve deficits, especially for oculomotor, trochlear and facial nerve were reported as a complication after ATL. Nonetheless, trigeminal neuralgia due to ATL is a very rare complication documented in the literature. The surgeons performing ATL procedures must be aware of the risk of trigeminal nerve injury, avoid excessive electrocautery use in the medial part of middle fossa and provide clean surgery in there to prevent this rare complication.
