We report here to draw attention to an uncommon complication that could arise from routinely performed procedure in pain practice such as percutaneous trigeminal radiofrequency ablation (RFA). We report a case of a 53-year-old female who underwent trigeminal nerve RFA for trigeminal neuralgia. RFA after adequate assessment with sensory and motor stimulation is performed as a routine procedure followed by 0.2 ml 1% lignocaine for dense sensory block at the target, following which the patient developed giddiness, nausea, vomiting, and nystagmus. After 2 h of rest and gaze fixation, her symptoms improved, with a decline in the severity of nystagmus. Symptoms gradually resolved over a period of 3 h. Proximity of the membranous part of the auditory tube to the foramen ovale might lead to such mishaps. Direct administration of 1% lignocaine into the middle ear via the auditory tube might be the most likely reason for her condition.
