Superior parathyroid gland approach to the recurrent laryngeal nerve

ABSTRACT

Background

The superior parathyroid gland is known to be almost constant in its location under the false thyroid capsule. Could it be a landmark to point to the site of incision of the false thyroid capsule and find the plane of the recurrent laryngeal nerve (RLN) during thyroidectomy?

Methods

The study included 48 patients with benign goiter scheduled for hemithyroidectomy or total thyroidectomy; there were 16 cases of solitary thyroid nodules, 27 cases of multinodular goiter, and 5 cases of toxic goiter.

Results

This study included 80 lobectomies. All patients showed no evidence of postoperative RLN palsy, bleeding, or hypoparathyroidism. The superior parathyroid gland was consistently found within the false capsule in all cases, whereas the inferior parathyroid was found within the same layer in 64 sides (80%).

Conclusion

The described approach can accurately guide dissection between true and false capsules of the thyroid to reach and preserve both the RLN and the superior parathyroid gland. © 2017 Wiley Periodicals, Inc. Head Neck, 2017
