Background: Trigeminal neuralgia (TN) is a well-known facial pain syndrome characterized by excruciating paroxysmal shock
pain attacks located in somatosensensory distribution of trigeminal nerve. Mandibularaffection is a common presentation of TN.
Objectives: Injection of mandibular nerve with neurolytic solutions in trigeminal neuralgia that was unresponsive to pharmacotherapy.
Determination of patients and Method: This prospective study included 21 patients treated for mandibular neuralgia by percutaneous
injection of absolute alcohol under guidance of CT image. Their ages ranged from 18-60 years and male to female was 3:4; All
patients suffered from moderate to severe TN and did not respond to medical treatment. Entry and trajectory of needle was planned
by CT and after local anesthesia. Alcohol was injected at the exit of mandibular nerve from foramen ovale.
Results: 85.7% of patients improved: 71.4% became pain free, who became 61.9% after two years of follow up.
Conclusion: CT guided mandibular nerve block by neurolytic agent as absolute alcohol and showing its effectiveness as minimal
invasive treatment option for intractable trigeminal neuralgia. CT guidance provided a clear view to secure the safety, accuracy
and selectivity of nerve block.
