AbstractWe report a case in which a mandibular nerve block using an indwelling catheter was employed for pain management in a terminal case of orofacial cancer. The patient was a 74-year-old female weighing 27 kg. She had a 27-month history of mouth floor and tongue cancer. The cancer recurred and spread to bilateral face and neck. The severest pain mainly originated from the right mandibular region. Two steps of pain relief were performed for the patient. First, pain control using 1% lidocaine or 0.25% bupivacaine administered intermittently or continuously through an indwelling catheter in the mandibular nerve was performed for 1 week to estimate the amount of pain relief thereby obtained. Second, a neurolytic block was applied to the mandibular nerve through the catheter. After the neurolytic block, the total dosage of morphine and diclofenac remained unchanged for 2 months. We conclude from the present case that this technique is an excellent means of obtaining long-term pain control in patients with intractable orofacial cancer pain.
