Convulsions Secondary to Hyponatremia Associated With Labyrinthectomy

Arch Otolaryngol Head Neck Surg. 1989;115(3):387-388. doi:10.1001/archotol.1989.01860270129028

• A case of convulsions occurring 48 hours following transcanal labyrinthectomy for Meniere's disease in a 76-year-old woman is described to illustrate the unexpected onset of severe hyponatremia after surgery. This syndrome is believed to be produced by inappropriately increased levels of antidiuretic hormone in healthy women without any associated medical condition. To prevent severe central nervous system damage and death, early recognition and appropriate correction of this cation deficiency is necessary.
