During the course of a parathyroid gland exploration on a 46-year-old woman, we sought in vain the right recurrent laryngeal nerve. The adenoma was easily identified in the left lower parathyroid gland, and the three other glands were found in their usual position. The left recurrent laryngeal nerve lay in the tracheoesophageal groove. The great vessels of the neck all appeared normal.
